Q: UxStyle Black Flashing Post-Windows Update Black Screen

Hello So on my computer something strange happens when I uninstall UxStyle It Black Post-Windows Flashing Black Screen Update UxStyle has broken my Windows install once and it has done it again The UxStyle Black Flashing Post-Windows Update Black Screen first time I kept on doing system restores to see what was the problem that made that black screen After trial and error I narrowed it down to UxStyle So I deleted Windows and installed Windows which is what I wanted in the first place Now I decided to triple-boot Windows with Vista and and it has succeeded I reinstalled UxStyle thinking it was just a problem with my old Windows install and then uninstalled it after a few days since I felt like the regular look was better I rebooted Windows and the same effect happened So I would like to know if I can get and replace those three patched DLLs with unpatched DLLs for Windows Could I just change the broken ones to have old next to them and then place the ones I get here there Also would sfc scannow work

Preferred Solution: UxStyle Black Flashing Post-Windows Update Black Screen

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.)

Hello lct01a, and welcome to Eight Forums.

A sfc /scannow will attempt to repair any modified or corrupted system files, so that would be a good first step.

I have an Acer aspire 5733-6607 with Intel Core i3 CPU 2.40GHz.

My mom was on it playing a game on the internet and stepped away to wash dishes when she came back it was on the black screen with the blinking cursor in the top left corner. I tried system repair disc, the recovery disc that it had me make when I first got the laptop and windows defeender offline nothing worked. I tried F8 and it goes to the black screen with acer and where I can press F2 or F12 and then back to screen with blinking cursor. I tried restoring default settings in the F2 menu also.

I was wondering if there was something someone knew that maybe I overlooked any help will be really appreciated thanks..

A:Windows 7 64 bit black screen with flashing cursor?

Unplug all USB devices from your laptop. Restart and see whether the blank screen problem remains.

It is possible that Windows refuses to boot with a USB device such as an external hard drive or a flash drive connected to your computer.

Hello! I recently got a windows 10 ASUS laptop, and I tried to install this theme on it. After installing it, I went to personalization, and clicked on the theme. The screen started flashing black and light gray, I tried rebooting, but to no avail. It starts off with the normal loading screen, and after that a flickering black and grey screen, I am still able to move the mouse around but it doesn't help. If anyone has any information on how to fix this problem I would be very grateful.

Here is a video of my screen:

I have Windows 7 Ultimate 32 bit. So, these are my problems described in the title. I cannot change desktop from black, only can set a picture as a background.

When I am in pictures folder for example, I see blank or black thumbnails.
When I right click and go to personalize, I can see black themes instead of actual pictures.

I tried almost everything.
- reinstalling video driver
- clearing thumbnail from disk cleanup
- resetting dwm.exe
- going into safemode and then restaring into normal windows
- I tried fixing shell by using "fixshell"
- clearing & repairing registry errors
- ran an error checker
- ran a file checker

I have Microsoft Office 2010 - I heard that it could be the issue, but maybe I am not right, anyway...

I attached a print screen photo.

And, I am hopeless, any help please? Thanks

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.

Hopefully I posted this in the right forum? Sorry, I'm kinda new to this...

So the log in page on my computer is not loading at all. There is no icon, no password, nothing, just the log in background screen. The screen also flashes a black screen really fast... When I put my computer to safe mode the same problem is there except the flashing occurs once every ~1 minute. Because of this problem I can't use my computer at all and I don't know what I should do next..

I have a HP Envy that I got about a year ago, recently (yesterday) it has been not booting up. What happens is when I press the power button it loads up and goes past the hp loading screen, but when it gets the the first windows loading screen, it kinda flickers from that to a black screen, also the on screen keyboard will pop up and go down all the time. Really not sure why it is doing this, can't even get on my computer. One last thing, if I wait long enough it will pop up with an error saying "LogonUI.exe - Application Error. The exception Breakpoint. A breakpoint has been reached. (0x80000003) occurred in the application at location 0x00007FFD23A5C753. Click ok the terminate the program" if I click ok it just start flickering again or just goes to a black screen.

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*.

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

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.

Behavior:

Boot is fine, once OS loads and Login screen is displayed Screen flashes to black at ~1hz. Each flash resets mouse position to center-screen. This is an intermittent problem, seemed to be fixed then reoccurs, have run Avast boot and full scans, spybot search and destroy, and comodo premium scans, does not seem to be viral (although i have heard similar reports of these symptoms from other members of OMGPOP.com). Have no symptoms if running in safe-mode. Often symptoms dissipate after if spy-bot fixes all problems found while in safe-mode. I have not recently added any programs to my recollection, nor has there been any major updates that I can recall.

Current action:
checking history of all recent program updates, and or any seemingly unusual reports in system logs.

I have recently run into a problem with certain games giving me a black flickering screen. The game is playable but it keeps flickering black every few seconds. It doesnt happen on all my games. I have an NVIDA Gforce 32MB card and 256mb RAM. I have Directx 8.1 installed (i've heard 9.0 has issues) The games that this is happening to are not graphically intense. For example it happens on Grand Theft Auto 1 and the game also runs slow. Also happens on Shogun:total war. But I can play games like return to castle wolfenstien without a problem. It doesnt appear to be an issue with the monitor b/c I can connect remotely and have the same problem. Any suggestions on how I can resolve this problem?

Thanx

Ok,
Well then I can reccommend a few things.
Check all your video card settings. Use guide here for help http://www.techspot.com/guides-hardware.shtml
Use a program such as NVMax to setup your video cards setting properly. Its a simple little program that allows you to change many settings easily. The tweak guide I mentioned explains what all the options do.
Theres always the chance its a problem with another program. It could be caused by a conflict with another program running. Go here for a useful program to copy a log of your StartUp: http://www.tomcoyote.org/hjt/
Posting that log here might prove useful.
Also, you mentioned RtCW runs fine, your probably using OpenGL for it. Maybe OpenGL is running fine, but Direct3d isn't.
Go to RUN and type 'dxdiag' to bring up DirectX. Run the test and see if all is well.

Test the hard drive. It is best to use the hard drive manufacturer's own diagnostic utility, but Seagate's tool will work OK on most brands. The diagnostic tool is run from a bootable CD (Windows does not need to be working. The first two steps are done on a working computer, while the third step is to boot the ailing computer with the CD that you create in the first two steps.) Please download SeaTools for DOS (CD) from Seagate's SeaTools for DOS web page or use the following direct download link to download the latest version of SeaTools for DOS:Download SeaTools for DOS ISO ImageThe downloaded file name is SeaToolsDOS223ALL.ISO[/list] Burn the downloaded .ISO image to a CD using the appropriate burning software.If you do not already have a suitable burning program for writing .ISO images to disc ...

Under Source, click on the Browse button: Navigate to and select the .ISO file that you wish to burn.Place a check-mark in the box beside Verify.Click

When the CD has been burned and verified as successful, it will be bootable. Boot from the CD.(You may need to access the BIOS Setup Menu or the Boot Menu and change the boot order to enable booting from CD before hard drive.)
From Basic tests on the Main Menu, run the Short test and then the Long test.

The results will be shown as either a PASS or FAIL.

I am seeing a similar black flashing screen problem on a Lenovo Thinkpad X1 3rd gen 20BSCT01WW.

This seems to have started after the Win 10 Threshold 2 update. My problem is so far limited to my primary (only) external monitor flashing to a black screen and returning a few seconds later. This only happens intermittently.
The Asus VX238H Display is connected via DVI out from a Lenovo OneLink Pro dock to the HDMI in of the monitor with a DVI to HDMI cable. I haven't experimented looking for the problem on the laptop screen itself since 99% of my use case is connected via dock to external monitors.

Below possibly worth investigating though the problem description is different. I definitely got a recent Synaptics driver update.

blackscreen after windows10 pro build 1511 update - Lenovo Community
...
I was able to isolate the cause of our black screen issues as the Synaptics driver for the touchpad. Uninstalling the Synaptics software instantly corrects our issue. Reinstalling it brings it back. I've tried the latest drivers from Lenovo (19.0.17.22) and the latest from Synaptics (19.0.19.1) and all produced the black screen.

Hi ShanShan,

First of all I am No Expert (disclaimer) but may be I can be of some help.

If the laptop was working fine for years and then out of nowhere went berserk ... that is kind of odd ... but I suppose it can happen ... I am assuming you left the laptop "On" while you were gone ... if it was showing a Black Screen when you came back ... now you might have gotten a power surge of some sort ...

Or may be a Bios glitch which I read somewhere awhile ago ... so do the following ...

1) Remove the battery and disconnect the power cord from the Laptop.
2) Press the power button for a few Second (While Battery Out and Cord Off from the Laptop).
3) Connect the power cord First. Press the power button to start and THEN dock the battery.

Did this fix your problem ... if so, you are good to go ... if not then ...

1) Try to reboot into "Safe Mode" ... on my laptop when I restart it I Tap repeatedly on F8 key till the Safe Screen pops up ... then choose "Fix My PC" or "Repair My PC" the minimum option and let it do it's thing ...

If you got a Normal Start-up ... then you are good so far ...

So, do a Normal Restart ... and see if your laptop comes up Normal ... if so, you are out of Hot water ... if not repeat Step 1 till you get to Normal Windows ... then

2) Go to System Restore ... and see when was your Automatic System Restore Point ... Tick "SHOW Older Ones" too and see which one you want to Revert back to that date ...

Do a restart normal again, if fixed then you are good.

I added couple of Disk Check links below since your brother suspects a Hard Drive Issue ... run those to make sure your HD is OK ...

How to Check Your Hard Drive for Errors in Windows Vista - For Dummies

Check your hard disk for errors

The How-To Geek Guide to Using Check Disk in Windows 7 or Vista

If none of these Solve your problem then probably you have to do a Clean "Recovery Startup" basically it will Clean wipe your laptop to Original Factory Setup ... I assume HP has a Recovery Partition ... like Partition D ... like in my Gateway ... it reinstalls Fresh from there ...

Post back your results.

G!

When power resumed, powered my machines back up. 2 out of 3 did OK. The third goes immediately to a black screen with a flashing cursor in the upper corner.
Have already:
1 removed and reseated the power and data cables from the hard drive
2 removed and reseated the RAM modules
3 tried pressing every F key on the keyboard
4 Cntl-Alt-Delete doesn't work either

A:black screen with flashing cursor

Hi michelletaylor, welcome to SevenForums !
This might seem silly but I have exactly the same problem with my laptop. I'm stuck at the page right after the manufacturer logo, the white line blinking page. One thing you can try is see if everything is alright in the BIOS settings by pressing F2 in the first page. You can also try pressing F12 or the key to access the boot options. Try to run a diagnostic scan. If it asks for an extended scan, say yes, it should take about 1h to complete and this might find problems. You can also try pressing F8 to access different options to boot your computer (like safe mode), but for me, it doesn't work. I would like to help you more but I have the same problem. Hope you'll be able to make it work and have a nice day. MrDub

My xp pro compuer is turing off and going to a black screen with a flashing underscore. I am able to manually turn it off and back on again. This started two days ago and has down this four times total now. It seems to be happening sooner and sooner. we use this computer as a media server for extenders around the house. any ideas what is wrong? while on, I check the temperatures and the s.m.a.r.t. on the harddrives and everything is checking out ok. the cpu temp is a little high (50-60 C). But this cpu has always ran this hot.

McAfee was saying that it had gotten rid of a trojan and that I had to restart. I restarted, but when my computer booted up again, I just got a black screen with the flashing underscore. I turn on the tower, then the monitor comes on. At that point I'm on the Dell logo screen where it has those F2 and F12 options. After a few seconds it just goes to that black screen. I've even tried doing that F8 thing for safe mode. Nothing happened. Is there any way to fix this? Any way to prevent it from happening again?

Hi Leminhh! Insert your Windows 7 Disk and see if you get an option to boot from CD/DVD. If not go into BIOS (F12 at Acer screen) and look for Boot Order and put Optical Drive or CD Drive first. Then SAVE and reboot.

When you can boot into the Windows 7 DVD, follow these instructions to do a Startup Repair. Startup Repair

If it doesn't work first time, try it three times. If it still doesn't work, please post back with what happens.

So far I have done a restore point, tried to reinstall windows from a recovery disk, I've used command prompt to Fix the boot record. Diagnostics says my hard drive is fine and I can see the newly installed windows 7 on my hard drive via the recovery disk boot. But when I try to boot from hard drive it still goes black.

Hello.
As you can probably tell I'm facing a somewhat common problem in the world of Windows computers; when I turn my computer on, it goes to a black screen with a flashing underscore/cursor. At first I thought myq problem was that I accidentally left my external hard drive plugged in, so I immediately unplugged it and rebooted my computer, however the problem persisted. I have a Dell 530S running Windows Vista Home Basic. I've read about putting in your boot disks but unfortunately, I do not have one. Any ideas of how I can fix my problem? Any feedback would be much appreciated.

If you can, get into the computers bios and check the boot devices order. Make sure that the internal hard drive is the first boot device. Also make sure that the bios detects the internal hard drive. If you don't see it, the boot drive could be dying or corrupt

Which Windows repair disc did you use and what option did you select?

Start the PC and press F8 as soon as you see something on the screen, keep pressing F8 once per second until you see an alternate boot menu which should have the option to "Repair..."

Launch the Repair PC option and see if restoring a recovery point or performing startup repair will fix the issue.

A:Flashing underscore on black screen at startup

I would first hit esc when your computer starts up and make sure that your boot order is correct.

That is that it is still trying to boot from your hard drive. If it is and you're getting that then I would pop in the Windows XP disk and see if it will start from there.

A:Black screen with flashing cursor on boot

Hi, KayChase1.
Your problem sounds very unusual, but possibly related to your BIOS settings.
Have you tried entering the BIOS menu on boot, and checking that the first priority boot device is your main Hard-Drive, rather than a CD-ROM, etc...
It sounds to me like the computer is trying to boot from a location other than the disc where your OS is installed.

I'm sorry for the lack of any technical terms used to describe this but I'm a complete novice with computers.

I was watching a video when some warning messages popped up saying something like harmful stuffs trying to access your computer, then it restarted. Now it starts up, goes to the motherboard thing, goes past that then hits a black screen with a little white line flashing in the top left corner.

I've tried to use F8 to enter the safe mode start up but when I press F8 it comes up with

'PLEASE SELECT BOOT DEVICE

SATA:3M-STM3250318AS
CDROM:3S-TSSTcorp CDDVDW SH-S22'

I tried the SATA option twice, first time the white line vanished so it was just a black screen and then it restarted. Second time it just went back to the screen with the white flashing line.

Any help in sorting this out would be greatly appreciated.

Nothing but Black screen (fan, leds work) after flashing the latest bios...

Is there anything I can do, or just new bios/motherboard can help? (I tried resting the battery, F8 key..) Thanks in advance

A:Black Screen after flashing the latest BIOS

I presume BIOS is screwed up. What you need is professional help with this so contact nearest service provider and ask for help.

By the way: check this forum using advanced search option. In the past I saw several interesting threads about BIOS recovering. I?m pretty sceptic about it but maybe you will be lucky and find solution.

Hi I have an older HP d SFF flashing after hdd cursor upgrade? Black screen with running WinXP I wanted to upgrade from the current Gb HDD to a new Black screen with flashing cursor after hdd upgrade?

I have a HP Envy Dv6. It was having problems overheating so i opened it up to clean the fan and air intake. I put it all back together and now I have a black screen. I can hear the hard drive spin but the fan only comes on sometimes. If i blow in the intake when the fans not running it starts to spin. The caps lock led is flashing constanly at a rate of 1 second, no pause, just 1 second intervals. Did i kill the fan or is the flashing telling something else. Any help is appreciated. Thanks

A:[SOLVED] Black Screen With Flashing Cursor

Welcome kitten831.

You tried reinstalling Windows 7 but the problem persists?

If you have the disc (which by the sounds of it you do), I suggest you boot to that disc again and go to Recovery Options, once in there, choose Command Prompt. Enter chkdsk c: /r

Might take a while...

If so, and that does not work then I recommend that you contact Tech Support and discuss the issue with them.   They may be able to resolve it relatively quickly for you.

A:RE: I'm stumped -- Getting Sometimes A Flashing Black/Static Screen??

I've seen this before, but it was after the machine had logged in and fully booted up at seemingly random times.

In my case, it was the graphics driver crashing because the graphics card stopped responding because the driver stopped responding (or so Windows thought).

There could be three things wrong here (in no particular order, and it could be a combination)

1. Graphics card is failing.
2. Graphics card is not getting enough CLEAN power from the power supply because of #3... (I don't see your PSU in your spec list you provided. What is it?)
3. Power Supply is failing.

Question: Does it do it in safe mode?

It shows the logo but then doesn't boot. It is stuck at the black screen with the blinking cursor. I have tried repairing it with my windows 7 disk by checking start up and everything else available on the cd. All the tests say it should be fine.

I have a Dell desktop computer with Vista installed. I bought it 2/2009. In July 2010, I went to get on the computer, and apparently it restarted for some reason but all I had was a black screen with a flashing cursor. I called Dell and they had me turn off the computer, unplug all external hardware plus the ether net cord. Then I unplugged the power cord from the back and pressed the power button for 10 seconds. Then I plugged the cord back in, powered it up, and it worked. The only problem is that every time it reboots, that is exactly what I have to do. Is there any way to fix this permanently???

A:After restart, black screen and flashing cursor...

holding the button down with no power is to discharge the energy on the main board and power supply, don't think it does anything else, is your system well grounded? if so then it could be a hardware problem, but Dell techs would know best

If you are brave and want to take a shot in the dark you could try a factory reset. On startup screen with the Dell logo , hold down Ctrl key, and at the same time tap F11 over and over. If you are quick then next screen will be a blue screen which will prompt you and ask if you wish to continue with factory reset. Click yes and continue ...

Hey everyone, I recently started having the black screen with the flashing cursor come up sometimes when I start my PC. I have narrowed it down as being my 3rd HDD (2TB WD) as the culprit, which I only use as media storage. It is not set as a boot device since windows is on my SSD and when I unplug the drive from my mobo, windows always starts up without any issue.

Basically my question is, is this just a case of a hard drive going bad? I ran chkdsk on all 3 drives and none of them had any issues and it is not fragmented or anything that I can tell, so I don't know. I have had this setup for a while now and about a month ago it started doing this. The screen doesn't always come up however, so I have no clue what the issue is.

Any help would be great, thanks.

Hello Hayman19,

Well, it seems you found the problem; however, the why may be a bit more difficult. So you can start off by running some additional diagnostics on that particular hard drive, check the smart data to see if there are any spin up timeouts, and possibly swap the SATA cables (with a known good cable), and if none of those work, you could try moving the HD to a different SATA port if available. Good luck.

I have an HP Pavillion dv6000, running with Windows Vista Home Premium.

When I turn on the computer, the HP intro screen turns on but then immediately goes Black with a white flashing dash in the top left screen. I can not access F8, safe mode, etc. I can only access the basic set up menu.

I never received a restore, or a Windows XP disc. Ive come to terms with the fact that I will most likely would lose my files and am willing to do a restore, but I can not get onto the log on screen. Do i need to see a tech? Please be advised I am not tech savvy and just want to get back on to my computer

Any help/links/disc downloads would be appreciated.

Thanks in advance!

Welcome to Windows Seven Forums.

What you are experiencing can be hard to fix, but it could well be the hard drive has gone to the big computer in the sky.

Hi, new to the forum.

I'm working on a dell inspiron 1525 for a friend. It came with vista but it was loaded with virus's. I formatted the hard drive and am now trying to install windows 7. The problem is that Everything that I am trying in just going straight to a black screen with a blinking cursor at the top left corner. I have done some research on this problem but none of the comments were from new installs. Vista was working fine except for being slow so i'm not thinking anything hardware related.

I've tried booting from cd, flash drive....and its all doing the exact same thing.

Any help would be great. Thanks

A:Black screen with flashing cursor when booting W7

First run the Dell Diagnostics from boot to test the hardware: Dell Diagnostics Utility - How to Run the . If they run then I would try to keep the Dell OEM Diagnostics partition - at Step 7 of Clean Install Windows 7 delete all partitions but it. Recovery will no longer run after reinstall so delete it too.

Use the installer provided in Step 1 of Clean Reinstall - Factory OEM Windows 7 burned to DVD or written to flash stick using tool in Step 2. Unplug all other HD's and peripherals, Boot the installer by tapping the F12 key at boot to choose boot device. If you get a flashing cursor it is not booting the device.

If problem persists Boot into BIOS setup, reset to defaults, save changes. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

When I turn on my computer all I get is a black screen with the flashing cursor up in the left corner of the screen. Any ideas as to how to correct this? I have a Dell from he'll computer-- inspiron E1505 about 8 years old and just had windows 7 home edition installed on it

A:Black screen with flashing cursor in upper left corner of screen

Hey I just went through something very similar. I found that my SATA cable connecting the hard drive to the motherboard had failed. I replaced it with a new SATA cable, and it booted right up. Try the cable first if you have one lying around, plus its a cheap solution. If you replace the cable and it still won't boot up, it might be your hard drive. Seeing as how your machine is that old, it could fail at any time.

Do you get anything on the screen when you turn it on?

Hello and welcome to the forum!

Do you still have the old Nvidia card to plug back in and see if it works. If it does, then try to remove and uninstall the drivers, power down, then put the AMD card back in and see if it works.

Hello Everyone,

My computer has a problem and when I turn it on, it loads to a black screen and then goes to a flashing underscore. I have tried using the F keys to boot in safe mode, but not even that works. The only thing it gives me is "Select from boot drives" and gives me three options. Floppy, Disc and HD. But still nothing works. Same flashing underscore.

System I have is: Win XP Pro, SP3, 32 Bit.

Thanks in advance for any help.

Hard to diagnose from a single minidump but it appears to be an attempt by your vga driver to write to read only memory ( a no-no). I would reinstall both your video driver and dcheck to see if there is a newer BIOS to flash.

Got a HP Probook 450 G0 here, which is powering up with no screen display. No BIOS, no nothing. It isn't the backlight. You can hear fans spinning up, the Caps Lock key starts flashing, but nothing else happens. I've removed RTC/BIOS battery, nothing. Removed and swapped RAM, nothing. Plugged into TV with HDMI, nothing.  I'm starting to suspect it's something more complex - a motherboard problem, a BIOS problem, or a CPU problem. I seem to remember older HPs having Caps Lock blink codes for reporting issues, but I can't see any info about that for the ProBooks. Any ideas?

Work through these Troubleshooting Steps for Windows 7 which will uncover most problems. Report back results as there may be other steps indicated.

Why did you install all of these other drivers? Did you already have performance problems or just create them?

Do you have a System Restore point still available before this problem began?

I didnt read what the blue sreen error was and restarted my computer.Now everytime I power it on it ask for boot device. I dont what to do, please help.

A:Computer crashed and has black screen w/ flashing underscore

You might try System Restore to a point prior. If that doesn't work open an elevated command prompt by typing cmd in search then right-click and
 
Run As Administrator and type sfc /scannow ( note space between 'c' and / ) and press enter. This will attempt to repair files if it can.
 
When it is done it will create a CBS log file. Then copy and paste: findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt
 
This will create a sfcdetails.txt to desktop which will show any files it could not repair.
 
From there open an elevated command prompt again and type chkdsk /f and enter. Then run chkdsk /r and let it run.
