Black screen, no POST, no BIOS

Q: Black screen, no POST, no BIOS

Hi, when I push the power button on my Asus k50ab all I can see
is a black screen and the power light on.
1. Windows doesn't start at all.
2. Even when I tried to start with my RAM removed it's the same, only black screen,
no sound, nothing.
3. I tried to shuffle my RAM around in any possible combination is the same.
4. I also tried to start with my HDD removed, its the same.
5. I tried (quite a lot) to remove the battery, unplug the cable then
press the power button for 60 seconds and then start without the battery,
but sadly no result. Even tried it with my lid in the lowest angle possible.
6. I also tried to plug a monitor to my laptop (I did also press Fn+F8 to change
displays), but still nothing.
If anyone has any idea whats going on I'll be very thankful.

Preferred Solution: Black screen, no POST, no BIOS

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A:New mobo cpu still no post black screen no bios

Its been seated and reseated, it doesn't look like anything is grounding it. It is on metal things that screws go into holding up the mobo, I have as many in as the mobo will allow (I think this is what you mean by stand offs), the old mobo worked fine with the same setup for about 3 years.

When i turn on my computer i heard no post beep and i got just a balck screen. I took out the memory no beep. I disconnected all the power connector except the one to power the mobo and no beep either. Any other suggestions or what you think is the promblem? thankz
 

A:No post beep and no bios just a black screen

"Sounds like a dead BIOS chip..." From the limited description... Power supply or motherboard may be bad. Bios chips fail more from bad attemps of updating or flashing rather than out-of-the-blue

A:emachines new graphics card, now black screen, no POST, no BIOS

Start by resetting the cmos. This will reset the bios to the default settings.

Remove the new card from the machine. Hopefully your computer will now boot up ok, using the onboard graphics.

Is your psu putting out enough power for your new graphics card?

2) Clear the CMOS via the motherboard jumpers to reset to default settings - but not sure what this will do.Click to expand...

You should perform this step, but remove the Radeon PCI card first.

The Clear CMOS jumpers are precisely for this kind of mischief- to return BIOS to a known/working state in case the system can't get to or complete it's POST tests.

Once you've cleared the CMOS, you'll need to immediately go into the BIOS setup screens and redo all your settings, date, time, HD's, etc.etc.

At that point, you may reset video to PCI (disable onboard) and re-insert your Radeon. With any luck, Windows will boot and the drivers will still be intact and working.

As far as the pause you are describing before the BIOS fun.. did you install .NET and Catalyst Control Center version of the ATI drivers? These are very likely the cause of your pause/longer boot time and user switching.

A:odd post/bios screen, plus no keyboard detected @ post

you could try removing the CMOS battery on the motherboard and using the jumper to reset the BIOS to factory defaults.

Always us a known good PS/2 keyboard. USB is OK after you have everything setup but unless you enable Legacy USB support in the BIOS the USB keyboard may not be seen by the BIOS (I've had this exact problem).

If the PS/2 keyboard is not seen when plugged into the keyboard PS/2 port move it to the PS/2 mouse port.

A:Black Screen During WIN 7 POST , Black Screen Even In Safe Mode

What other graphics adapter choices are available in BIOS setup? If you choose Switchable is there software on the Lenovo site for your model that's needed? Are you using the Display adapter software from there?

Have you tested your HD with the maker's HD Diagnostic extended CD scan, followed by a full Disk Check on a single disk partition you create?

Then work through the steps for Overcoming Windows 7 Installation Failures - Windows 7 Help Forums including trying an alternate install method (disk><flash stick) with new media. These steps overcome almost all install failures, so you'll be reasonably sure the problem is hardware or BIOS settings if nothing works. But don't skip any steps.

Try Clean Install Windows 10 Technical Preview to see if there's any difference with a more modern OS install. It's already a very polished OS and worth testing this.

Hi,

I've been working on a dell inspiron 1525 today and cant figure what is causing this problem.

The laptop boots, displays the post screen, and then the screen goes black.
You can boot into BIOS,
You can boot into the Boot menu.

You cannot boot into safe mode, the f8 key does nothing,
when using the boot menu, u can't boot into a windows disc to reload the operating system, it just goes black.
I did however manage to boot into a linux cd i have and run a HDD test (what passed) and a memory test (what also passed).

It does exactly the same on an external monitor aswell so I am lost with this one.

Any ideas would be appreciated

Then it froze, so i restarted it from the button on the tower. Then when i turned it back on again, after the POST screen finished, the windows bar should of came up. but it didnt. A black screen came up. What do i do?

A:Black screen after POST

After POST start hitting the F8 key to get to the Advanced Boot options. Try to get to Safe Mode. Try to run the Virus Scan again and delete the virus file. Then go to Start/Run and type CMD and hit Enter. In the command prompt type chkdks /f/r and hit Enter. Then type a Y and hit enter and reboot the computer. The Check Disk Utility will run at next bootup to try and fix any errors on the Disk.

Well I seem to have found my problem and fixed it. Apparently when my friend installed Win 7 to the HDD it failed to create a master boot sector. That is why the partition of Win 7 was still located on the drive, but it was unable to boot up. I formatted the entire drive and installed a version on XP I had and booted it up within an hour or so. It is such a relief to figure out I did not mess anything up assembling my first PC!

Hi,

when turning on my comp I get the lights flash as usual, but no audible beeps. The monitor is black, and I do not see a thing on it at all (ie no logo, checking RAM, etc)

Have tested the monitor, that is fine. As computer is old it has on-board graphics (so i cant remove the card and replace it!)

The keyboard initially lights up when I hit the power button, but then goes 'dead', ie caps lock and num lock etc dont turn on the relevant lights.

I hope you can prove my suspicion that my motherbaord is 'fried', to be incorrect!

Thanks in advance,

since you haev changed yoru power supply and you say that teh processor fan does move then the power is reaching the board.

if you remove the RAM from the board, and start the pc , do you get the beeps? if you dont then there is apossible problem with the board.

Can you boot to safe mode?
Can you from safe mode run system restore?
If you can operate system restore from safe mode do it back to before you removed programs.
If you cant boot to safe mode your hard drive might have crashed.

does the bios see the harddrive?

if you know the manufacturer of the drive, try running their hd diagnostic utility. You can download it from their website.

Hello I would like to write something better for my first post but I have a big problem with my desktop After a couple of days using the quot sleep quot after screen Black POST function Black screen after POST without shutting off the computer I finally shut it down and when I powered it on again appeared a black screen with a blinking white space in the upper left corner The first thing I tried to do was to use a bootable usb stick my desktop doesn't have a cd dvd to load the windows rescue utility or a bootable OS such as ubuntu The problem is that when I accessed the BIOS it didn't recognize any usb stick This is really awkward since I installed both Windows and Ubuntu through usb I double checked the usb sticks I was using and they definitely work I tried them on a laptop with Windows installed I then tried various steps to solve the problem reset the BIOS through the CMOS jumper on the mobo disconnect every device apart from AC power keyboard and screen disconnect one of the memory sticks change the slot where it was allocated and repeat the operation for the other one disconnect the second HDD Without any result I have installed Windows Ultimate and Ubuntu with GRUB loader The hardware is as follows Motherboard Zotac ION Itx-B HD OCZ Agility SSD Gb HD WD Caviar Green SATA Tb Memory Corsair XMS Mhz x Now I'm absolutely stuck

A:No POST and black screen

Id say you've narrowed it down to the mobo or processor. A local computer shop may be able to test the processor. There is a chance you damaged the die but the mobo will usually give a beep code but not always.

I've been having some issues with my PC. The short version of the problem is that I can turn my computer on, use it for a while, but then if I restart it, I can't get it to even post to the bios screen. I'm assuming it's some type of overheating. How can I tell specifically what the problem is though if I can't even get to the bios screen?

I'm using a different computer right now, and have the other one unplugged and have a feeling it'll turn on again in about 30 minutes.

It's an Athlon 64 3700, Asus K8U-X, and a 550W power supply.

For starters this is not my computer, I'm attempting to fix a friend of mines laptop. I have no idea what he was doing prior to this meltdown but the computer will no longer boot so far as to get to the windows login screen. I have tried booting in safe mode on all different settings but after the bios readout it just goes to a black screen with the pointer (same as reg boot). Anyone know what might be wrong? Is his computer shot?

Thanks in advance for the help!!

you could try the start up repair. If his computer passes POST more than likely hard drive is the issue Did you hear the normal two beeps or are there any beep codes you hear.

Just purchased new refurb PC's for my wife and Black Screen Restart Post on Screen BEFORE I It's all I Black Screen BEFORE Post Screen on Restart could find with Windows still available They are both HP Pavilion p - w bit Desktops running Win Home Premium SP During Windows setup of PC it asked for a restart When the PC powered back up it had a black screen from the start before the Post screen I power cycled it several times with no luck Even switched monitors and video cables The next morning it started normally with perfect video I assumed the Refurb PC had a problem and set it aside for return Been setting up PC for a few days now with lots of restarts All was well until I did a restart just now There was the identical problem Power cycled the unit twice and still had the black screen Then I unplugged the PC and pressed the power button to discharge the capacitors fans ran for a few seconds When I returned power and started the PC again it functioned normally I've done quick restarts since to try and replicate the problem but it only happened that once I love these PC's and I love Win so I hate to give them up But I don't want the video freezing up on me every time I do a restart I assume now that PC is not necessarily defective Since this is occurring before the post screen I wasn't sure if it could be windows related Has anyone run across this If so and suggested solution Thanks very much sorry for the long post

A:Black Screen BEFORE Post Screen on Restart

That does sound quite strange that they both do it
The answer to your question is no, windows has nothing to do with post, power on self test as the name suggests is controlled by the bios and is the motherboard checking hardware etc when the post is complete the bios will start the boot sequence as set in the bios ie 1st boot device then 2nd device then 3rd if necessary until an OS or bootable device is found, I can think of no reason for a machine to not post other than the wrong display output being selected if the machine has more than one ie on board gfx and gfx card installed or multiple display ports present or finally an overheated gfx card that has shut itself of until cooled but having said that if it works it works so I would see how it goes

You can check bios settings for gfx outputs and I would monitor temps as well don't really know what else to suggest

Hi Everyone,

I hope someone can help me with my issue.
I recently built a core 2 extreme machine with a Gigabyte 965P-D23 mobo.

When I turn on the computer, all the fans turn on but nothing appears on the monitor. Nothing beeps either.

My RAM, graphics card, psu, and monitor have all been tested on other systems and confirmed functional. I have swapped out psus and the same problem remains.

I have reset the cmos using the "shorting the pins" method and battery remove method to no avail. Is my only option now to buy a new mobo?

Thanks,

meebee
 

A:No screen, no post, no bios, no hope?

"Is my only option now to buy a new mobo?"...

Check to see that the motherboard is not shorted to the case. If it is not shorted, make sure you have connected the 4 or 8 pin CPU power connector to the motherboard near the CPU... Then replace the motherboard

I just bought a gtx 970 to replace the 9750. I did a new install on a new ssd. I installed all the appropriate mobo drivers and now it's time to install the geforce drivers. I shut off the computer, connected the 6pins to the video card, and made sure the video card is secure seated. Turned on the computer and noticed the post screen, but it lingers for a while then I get a black screen. I'm not able to enter the BIOS.

Could this be a faulty video card?

A:Power on, no post, no beeps, black screen...

If you had a thunderstorm and lightning, it could be more than one component, but the likely suspects are power supply and motherboard.

Here is a way to troubleshoot from member TVeblen:

Strip it down and then add components back, one at a time, to try and isolate the offending component.

The test (power off, power cord unplugged):
• Disconnect everything externally connected except the mouse and keyboard (printers, USB devices). If you are not using a wired mouse and keyboard see if you can borrow one.
• Disconnect the power and data cables from all the drives inside the computer (Hard drives, DVD/CD drives).
• Remove all the cards installed in the PCI slots including the video card. (be careful handling them and place them on a non conductive surface while testing).
• Remove all the RAM sticks (same rules as above).
Now connect the power cord and turn the PC on.
• The motherboard should start beeping. You should get a beep code that tells you there is no memory. This is good, it means the processor is functioning and the motherboard is good so far.
• Now add one stick of memory in Slot A1 and power on. More beeping: "no video card" beep code. This is good.
• Then add the video card and connect it to the monitor. You should get no beeping and you should see the BIOS screens, ending with the message that there is no boot device.
If you get no video then switch the one memory stick installed for another one and test.

Continue adding components one at a time.

If at any point the PC fails the the last component added was the problem one.

If you removed everything and there is only the Motherboard (with integrated video), processor, and power supply to contend with and it does not POST or show anything on the screen, then the problem is one of those three.

If you have tested by using another power supply then you are down to two. CPUs rarely fail, so motherboard is the most likely guess.

Try performing a CLRTC or Clear CMOS as a last ditch effort, and check the 3v battery. Both long shots, but what do you have to lose at this point.

Firstly my front usb's stopped working for a day, no other problems at all b4 this.

Then i was away for a few days (computer off) on return computer would not boot. no beeps. no post, just fans and black screen.

I tested the two ram modules and both have some led lights, i tried taking one out/ then swapping them etc no difference.

I thought then it was the mobo, i replaced it w a (untested) secondhand mobo.
This time fans start for a moment then stop, still no post no/black screen etc.

I tested the power supply in another mobo/old sys and it powered up and there was post sound.

I have now found that the fans work when the 4pin atx12v is not plugged into the board. as this powers the chip i am wondering if the chip is fried or if it may be something else?
 

A:Fans work /no post - black screen

more info:

I have also replaced the power supply with 600w jeantech

also i have since tried to disconnect all power to all but the mobo and 4pin atx 12v - still same problem

i have removed all the pci cards and graphics card - still no joy

So what do i have left to do? disconnect any other drives completely and check for poss shorting of mobo?

The cpu and ram have been reseated when i replaced the original mobo

any help much appreciated

why do fans work when atx 4pin is not connected but not when it is connected?

obviously the system will not post w this disconnected but why do the fans run?

thanks

Good afternoon!

I'm in a strange problem.
My netbook's screen shows black during POST (Bios), and sometimes shows some white lines, like interferences.

If I start Windows 8.1 OS the problem persists.
If I run Ubuntu, I can see everything normally.

I looked over screen connection and touched it in order to check the wire is ok, but is the same.
If I connect an external VGA screen I can see everything right.

Years ago, I changed the screen because It brokes.
During last months, I could see lines in screen mostly during POST.

It could be a problem from screen, wires...?
The screen doesn't support some frecuences now?

Thanks and sorry for my english.

My netbook is a *NB520*.

Hello!

Vista SP1
2gb ram
Asus M50vm

After a normal shutdown my laptop no longer boots. It posts fine, then displays a black screen with a flashing cursor in the upper left of the screen.

So far I have done the following with the Vista Restore Disk:

-Pulled up a command prompt and verified that my files are intact on the HDD

-Run the Vista diagnostic

-Used system restore to rollback to an earlier restore point
None of the above had any noticable effect. I will attempt to reinstall Vista later, but beyond that I am unsure what else to try.

Anyone have any ideas?

Thanks!

From the command prompt type

Code:

See if that helps, also is the BIOS set to boot from the HDD?

Hello, just finished putting another system up. I ran into a problem tough, when I booted the computer for the first time, all I got was a black screen. No bios, no post beep...

The setup:
MSI p6n SLI V2
Core 2 Duo E8200 2.66GHZ 6mb L2, 45nm (not compatible?)
Sparkle 8800GT 512mb
2Gb G.Skill DDR2 800mhz

The PSU didn't have a 8 pin 12v connector which the mobo had, so I didn't connect it. I will roam around the local computers stores for the cable today and see if it helps (hopefully thats the problem).

I fear it was my mistake tough, with the CPU choise. I tought the CPU list on MSIs site was of all the compatible CPUs and didn't notice that it said "in testing" on the side... damn.
 

A:No post beep, black screen on first boot

You absolutely need the correctly configured power supply to work with a motherboard and video graphics card of that quality.
The MSI website and the Core 2 Duo webside will advise you on capatibility between the two.

Hello,
(This is my first time posting here, so sorry if this is the wrong section or anything)

Tachyon-PC is being slow to boot its OS. Ironic, right?

Lately my laptop has been experiencing a problem when I boot it up. After the "Toshiba: Leading Innovation" POST screen, a black screen pops up that lasts for 4 minutes, 20 seconds on average. This black screen has a grey underscore (_) in the top-left corner, like a terminal. Afterwards, the Windows 7 splash and then login screen will appear as normal.

-I went into BIOS and set my boot to Fast Mode; that didn't help
-I was told to see if the on-die or onboard cache has been disabled; however, on my Satellite L875's BIOS, I can't seem to find an option for it.

Any help would be highly appreciated.
Thank you.

A:Computer won't boot - No post, black screen

It sounds like a heat problem to me, and it's possible that the warm air from the hair dryer was cooler than the CPU and cooled it down enough to restart. So, the question is, are you sure the computer is too cold to run? Use the computer with the case open, or try blowing air from a fan into the case and see if the same thing happens - because I think it's getting hot and shutting down.

A:Well, lads, managed to black screen myself, but it it won't POST, either.

 Normally when I have similar conditions, I try booting to Safe Mode first.  If that doesn't work, I boot from a Windows repair disc and do a repair.  If I still have a problem, I boot from a Linux Mint or Ubuntu disc.  I've never used a Hiren's rescue disc because the things I mentioned always worked for me, but if it's a stand-alone disc that doesn't depend on using something from your hard drive, I'd wonder about the graphics card.
 
Good luck.

I was able to get into BIOS and boot from the windows CD. A system restore fixed it. I'm just wondering what you guys think was likely to have caused it. Is it likely that my boot files got corrupted somehow? I ran a diagnostic and from Seagate and it says that my hard drive is fine - but I'm not sure if that's just because I recently restored Windows.

I did recently install a big name game - but it ran fine for three days before this happened. The system restore point I had was from when I installed it, so it's now gone.

What do you guys think could have caused it? I'm just a little concerned that restoring only patched over a problem that will crop up again - or, that I should be afraid to install that game again.

Thanks in advance,

Chris

Have you run a full disk check?Open Windows Explorer (<WINDOWSKEY>+<E>)
Click "Computer" in the left pane
Right-click on your hard disk, then select "Properties"
Click the "Tools" Tab
Under "Error Checking", click "Check Now" (You may need to respond to a UAC Prompt)
Make sure both options under "Check disk options" are checked.
Click "Start"
If the "Windows can't check the disk because it's in use" message comes up, click "Schedule disk check"
Reboot the computer, then allow the disk check to complete (it could take a while, because it will be checking the ENTIRE disk)
I mention the above because inexplicable slowdowns and boot failures are symptoms of a failed or failing hard disk.

Hi There,

I have Dell Optiplex 3010 machine in which the POST bios logo (not windows splash screen) appears some other instead of Dell manufacturer logo. How can i change that back to default so that when POST happens i can see the Dell logo?? I have tried reformatting the machine but still the logo doesn't show the Dell logo . Can anybody help me with this.

Thanks in advance.

A:POST Bios screen logo change

I'm not sure what you are referring to. Post BIOS would be when Windows loads.

Post on the Dell Community forum, that is probably the best chance to get an answer.

My computer is running Windows 7 Home Premium x64 and after POST it goes to an all black screen with a _ in the top left.

This started with a blue screen after waking up from sleep. I have re installed windows 3 times now and it happens again after 2-3 days always the same after waking up. It will boot ant thing else i can think of from UBCD to Linux and the install CD. The install CD however will not run Start-up repair saying it is not the right version of windows even when i installed it 2 days ago with that exact CD. i"m normal very good with computer but this one has me stumped and i don't wish to re-install again as it takes quite some time as it is a rather unique setup.

Thank you for any help you can give

That could be any number of things such as it trying to boot to an Optical drive that has a disc in it but is not bootable, has a USB drive plugged in or a printer with memory stick slots or USB port on it. Basically it's looking for boot files and can't find them, could be the HDD has gone bad.

It's back again First time making a post about it though since before I've always had system restore points to save my sorry ass - but not this time I updated to and POOF there they went Problem Immediately after the windows splash loading circle spinny thing I get a black screen with cursor across all three monitors or one Fight! Post Round 5: Splash Screen, Black monitor if I unplug the other two - doesn't really make a difference If I let the cursor idle for about two seconds it disappears then will reappear if I move the mouse I can wait five or thirty minutes it will stay black As I mentioned before the only way I was able to fix this the other billion times it's happened was to system restore The first time it happened I had to fresh install windows which I definitely know DOES fix it but it's also very impractical Hard rebooting from the black screen solves nothing as it just boots back to it Causing a load failure boot into automatic repair since I can't get into safe mode any other way also how I would get to system restore if you were wondering and entering any of the three safe mode modes does nothing The central monitor gets no input and the other two just say quot safe mode quot in each corner over a black background Keyboard input does nothing The safe mode text flickers rapidly for the first couple of seconds after it loads then disappears and will reappear if I move the mouse the cursor appearance disappearance is the same in safe mode I am running with a x on the most recent drivers I have the integrated gpu disabled in device manager There is no apparent trigger at least that I'm aware of - perhaps background updates which causes these quot blackouts quot For the love of all that is holy can any of you wizards help me with my problem p s I'm willing Post Splash Black Screen, Round 5: Fight! to spend money swapping components out to fix this I'm not especially tech-savvy but I always have suspicions that the iGPU is somehow behind all this Or maybe my motherboard Or SSD Maybe even my windows installation Last time I fresh installed windows I used a CD I burned from back during the upgrade promo but then again I always figured that windows updates - and especially having recently upgraded to windows - made your install source irrelevant UPDATE I left it on the black screen for minutes and it gave me a login screen Not sure what to make of it but I'm not going to shut it off to test it again just in case one of you suggests something that I need the computer on for

My teacher has been experiencing problems with her computer. First she said she could not get it on they bought a new powersupply and I found that it was not the power supply but the Power Cord was blown. Once I got the Computer back together after they took it apart. I plugged it all up and it turned on but the drum light is flashing really fast or it is staying on and it is frozen at the bios screen saying press del to go into bios setup or press tab to go into POST which is Power On Self Test. But I press either key and it just beeps and it does not do nothing. I am not sure what to do about it.

A:Froze at the BIOS screen the one that says press del for setup or tab for post.

Check all the leads are connected firmly from the power supply to the motherboard, drives, etc. and the IDE cables. Then remove the CMOS battery for 20 minutes, replace it and reboot.

Are you getting any POST beep codes, or does it just beep when you use the keyboard?

Unless your controller supports hot swapping, I would NOT do that again.
Have you replaced the sata cable and or tried another sata pw connector?

FWIW just because a disk passes the drive maker's diagnostic, does not mean it is OK. I had a system a few weeks ago that passed ALL tests twice and I zero filled the drive; still problems. Installed a known good seagate drive, all problems stopped.

Was infected with a screen block virus yesterday (ukash) but was able to use safe mode to run AVG and MBAM to clear. Normal mode was accessible again and screen no longer blocked so ran MBAM again but kept sticking. Ran again overnight but now have black screen (no taskbar, no option to ctrl+alt+dlt). Safe mode was running normally until I followed advice to edit the drive names in regedit.exe as a solution. Since Safe Mode is also now a black screen so can run no diagnostic tools. Can ctrl+alt+dlt in safe mode, no other functionality.

I am running Windows 7 on a Sony Vaio laptop less than a year old. Came preinstalled with Windows. I have license key but not discs.

ASUS M5A88-V EVO mobo
AMD FX4130 CPU
W7 Pro 64-bit
AMI BIOS

On boot-up, the AMI POST screen flashes by so fast there's no way to read it.

I have tried various BIOS Quick-Boot, Full Screen Logo, Force BIOS settings, together with mashing the keyboard's Pause/Break key. The 'del' key only takes me into the BIOS itself!

None of these work. I see the red and blue (I think?) AMI boot screen for about 1-second then it's gone followed by a normal W7 boot.

How can I read those start-up POST messages? I know this is a common problem, but has anyone ever solved it? Taking a video of the monitor screen during boot-up doesn't count as a solution!

A:Start-up BIOS/POST Screen Message(s) Too Fast to Read

Is there a newer BIOS update? Try setting to defaults after taking note of SATA settings. Then see if disabling quick boot helps. What other settings choices?

Within the past week, my computer kept randomly rebooting, and eventually stopped turning on at all, so I bought a new PSU, and now it boots, but only to the POST screen, I try to press F2 to load the BIOS, but it does nothing. I also tried changing the jumper to boot into the BIOS setup, but it still stuck on the POST screen, but says "setup loading" instead of "press <F2> to enter BIOS setup" I am completely lost and have swapped out and checked the PSU, RAM, GPU and CPU. I am afraid it is a motherboard or HDD problem. Anyone have any ideas? Thanks for your help!

(Also, there are no beep errors, of course! >_< )
 

A:Computer won't load BIOS! Stuck at POST screen! I am clueless ;(

Most probably, this is a HDD issue....Try this to verify:

- Take out the HDD IDE cable
- Switch on the PC..keep hitting DEL till it takes you the BIOS Stup screen...

If you can reach the BIOS Setup, it most prolly is a HDD issue....
Jyust to verify, you may want to try booting from aCD ROM if the above works

Now it hangs on the BIOS POST screen.

Frankly I hope you have backups!  IMO do not fool around send it back, there a few thing that could be the culprit.  If you get it more screwed you may have a hassle when you send it back.

Hi,
I'm new to the forum and have quite a big problem. So any help is welcome and appreciated.

My Satellite Pro A200 goes black after the BIOS screen and a black screen with a blinking cursor. Also just before the screen goes black a bleep can be heard which shows windows is booting.
I can access the toshiba set-up screen but not the safety mode set-up.

Kind Regards

A:Re: Satellite Pro A200 - Screen goes black after BIOS screen

Hello

You wrote that you can access the BIOS but have you checked if the HDD is recognized properly? Maybe the computer cannot boot because HDD isn?t recognized so you should check this.

If the HDD is recognized I would try a recovery installation from Toshiba recovery disk. It seems that Windows isn?t able to start and if you reinstall the whole system it should help to get rid of this. Just go in boot menu and select CD/DVD drive as boot device.

Check this!!!

A:Black screen after Blue Screen, no BIOS, no display

Can you boot into Safe Mode?
Does the system display the Asus splash screen before going to the black screen?

Have you checked to see if the video card has power (the extra power plugs in most cards these days)? Have you checked to make sure the fan is working, and that the video cooler isn't clogged up?

Have you tried another video card? I'd suspect that the video card or it's drivers are your issue. If the system boots into Safe Mode, then I'd suspect the drivers, if it doesn't boot into Safe Mode (so you can see the display) - then I'd have to assume that it's the video card.

See if you can return the video card. If not, then see if you can borrow one from another computer - or buy one that you can return if it's not needed.

Good luck!

Since you are having a graphics issue in both the BIOS startup screen and while Windows is open, it does sound like a graphics card problem and not a driver problem. Do you have another graphics card to substitute for test purposes?

Sounds like you are hanging at the Bios loading point with the new OS.

Check with the mother board manufacture to see if your Bios is up to date and compatable with Xp Pro. If not, you might want to update the Bios and see if you can at least boot into safe command prompt.

A:Black Screen after BIOS

Try another SATA port.

Check the BIOS boot order to set SSD first, HDD second. If you need to boot a disk or stick use the BIOS Boot menu key at boot.

Did the HD have an OS at one point? It may have boot code remaining that needs to be wiped with Diskpart Clean Command after moving the data off.

I have Vista Ulimate 64-bit and everytime that I reboot I get a black screen before the Microsoft Windows scrolling bar.

This is the sequence.
- I reboot.
- I get my bios information screen.
- I get the white, blinking line in the upper left corner of the screen.
- Then the screen goes black with no hard drive activity.

I then can perform a Complete PC restore from my second partition on the same SATA Hard Drive and I will then be able to boot into Vista with no problem.....until I reboot, then I get the Black screen again. It is a vicious cycle.

I have tried to remove video cards (2 x 8800 GTS), memory (4 GB), sound cards (X-Fi Music), load the default bios settings....nothing works. Only a Complete PC Restore cures it, but only until I need to reboot the PC.

Any help would be welcome.

Just a guess here, but to me it sounds like a boot loader or boot device order issue. How long have you left it on the blinking cursor before giving up?

A:Black screen after BIOS load screen

If you have any USB devices other than keyboard and mouse, disconnect them, and do a hard shutdown by pressing the power switch down until your computer switches off.

Wait half a minute or so and try booting up again.

If that doesn't work, are you able to boot into Safe Mode?

Failing that you could try a repair install.

Hello I am having an unusual problem with Desktop PC Sometimes when I boot the computer it will show the Gigabyte splash and then go black the moment it switches to what would have been the quot starting windows quot screen I am positive that it after BIOS screen Splash Black is not Black screen after BIOS Splash the monitor because I never hear the Black screen after BIOS Splash windows login sounds or music When this happens the only way I am able to fix it temporarily is by re-slotting the memory sticks in the motherboard I did this on a suggestion that it may be a bad stick but based on my experience of switching them out and using them separately this doesn't appear to be the case Any suggestions on how to proceed Thank you for looking Desktop Windows Enterprise GIGABYTE GA- A-UD P AM AMD SATA Gb s USB ATX AMD Motherboard AMD FD FRHKBOX FX- FX-Series -Core Black Edition MSI NVIDIA GeForce GTX OC GB GDDR DVI HDMI DisplayPort PCI-Express Video Card N TF GD OC Corsair Vengeance GB x GB DDR MHz PC Desktop Memory CML GX M A C

A:Black screen after BIOS Splash

I have had similar issues, but sometimes it can be a combination of issues rather than just one.

First I suggest you reset your BIOS, then configure as you need it. Then disconnect all SATA connections except your boot device. Also and even more importantly disconnect ALL your USB connections, including mouse and keyboard.

Boot... see what happens. Boot a few times to make sure you have a consistent response.

All well? try reconnecting SATA devices one at a time booting after each addition. All not well, determine the SATA device causing the problem. Try it on a different SATA port to determine if the port on mother board is the problem.

Repeat with USB devices.

lf on the other hand after removing USB and SATA devices you still get this problem, run memtest. post results.
