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 (This link will automatically start a download of Reimage that you can save to your computer.)

The H77 chipset does not allow you to alter CPU voltages. That can only be done on a Z77 motherboard/chipset.

Hi, could someone tell me what the differences are between these two boards please? Also is the Gigabyte equivalent worth considering over either of these two? (What actually is the Gigabyte equivalent?).


A:ASRock H77 Pro4/MVP vs Asus P8H77-V

They are both the same chipset, but from different manufacturers.

I have Corsair XMS2 DDR2-800 memory - I overvolted from 1.8 to 1.9 volts thinking that it would make it more stable when I overclock them to 1066. Wrong. When I saved the change, my computer shut off, and when I turn it on, it gets no display or no POST. Can .1 volts really fry something?

i had 4gb or ram but then i added another 4 to make 8gb or ram, but i am getting bsod. how do i change the voltage to match the ram?

A:bios voltage change

Are the RAM sticks the same make and model? Are they the same voltage. Mismatched RAM sticks will always cause BSOD's. It's very important to get matching memory.

I recently purchased a new PC with a ASUS P4800 SE mobo. Am having a problem however. Whenever I play any games after about 10 mis or so I get a warning that my 3.3V is too low (drops to about 2.9v). Once I exit the game (even alt-tab) the voltage goes back to normal. If I keep playing I get a corrupted display (lots of lines and gibbrish).

Any help on what this is - and why it is happening would be helpful.

For reference my specs are:

P4 3.0E Mhz
512 MB RAM
ASUS P4800 SE Motherboard
ATI Radeon 9800 Pro 128 MB Videocard
Generic case with 350w PS.

Temps during idle are about 40 C for CPU and 35 C for Motherboard, rising to 55 C for CPU and 45 for motherboard during gaming.

Help please?

most generic power supply's are over rated power than what they actly tell you with a sticker slapped to the outside of the case,Most run at 200 to 250 max,the vid card you are running needs lots of juice,If you are running the proper driver on this card and you still have the same problem replace your power supply with a good quality 350 watt.

I have changed the FSB to 200 and overclocked my 2500+ Barton. It is running quite nice at 2.195 GHz with an idle temp of 40C, increasing an additional 5-7C with a load.

The voltage setting in the bios of my A7N8X Deluxe 2.0 is currently set at 1.65v. MBM5 and Asus Probe readings both show voltages fluctuating between 1.71v and 1.73v. Is this normal for the voltages to be that different from the bios setting?

Thanks, Al

Yup thats normal on the pretty much the entire ASUS A7N8X series of motherboards. The actual voltages are closer to the voltages reported in the BIOS then what is reported by the monitors and it can flucuate as long as it isn't by very much.

Your BIOS will automatically detect the increased demand for voltage and adjust accordingly. Don't mess with RAM voltages yourself as you can mess your motherboard and RAM up, speaking from experience here.

Hello, I just recently got a new ASUS P8Z77-V LK motherboard along with my i5-3570K. I'll get right to the chase: The motherboard is showing some wacky readings in the temperature and voltage department. I installed ASUS AI Suite and every once in a while ill get a warning about some voltage reading like "Warning! X.XXV Vcore" and in software used to measure the temps they are really weird.

Here is a screenshot:

Notice the negitive readings in there... A little odd. How do I fix it?

Also I can assure you the system is very stable, I have run multiple benchmarks with no crashes.

Here is a speccy screenshot:

Thank you for all he help!

A:ASUS P8Z77-V LK Wacky Temperature and Voltage Readings

First thing I would do is try other monitoring software to see if they show the same results, try Asus PC Probe rather than the full AI suite. Wildly anomalous readings with no instability or problems would indicate to me that the monitoring software isn't reporting correctly or the sensors aren't outputting correctly, just a thought.

A:How do i change the voltage to DDR

Should be an option in your BIOS to increase voltages. Don't go mad with increasing it though or you'll just blow the RAM. Just do a single increment at a time.

How many sticks of RAM/how much RAM do you have? You could try removing some sticks so you only have 2GB in.

Hi everybody,
i have just started over clocking and so far i have done my video card, and a bit of my cpu. however, i cant seem to get the fsb to 200 which i should. everytime i change it to 200 in the bios and i restart, the computer turns on, but the monitor turns off. i am assuming this is due the insufficent voltage. so my question to you is, how can i change the voltage if there is no setting in bios, and is there a program that supports amds that i can download to tweak the voltage. thanks.

A:How do i change the voltage of my cpu???

In the bios there should be a setting for cpu voltage, usually called "vcore" or "vcpu." Don't increase it too much, and watch your cpu temperatures.

I currently just got new ram from Crucial and I am not sure how to change the voltage setting on the ram. Here is what they said to me in the email:

"The replacement modules you will be receiving incorporate a new chip build,
which operates at a lower voltage than the modules you are returning. The
original Ballistix modules operated at 2.2 volts, while the newer build only
requires 2.0 volts. Please make sure this adjustment is made in your system BIOS
prior to using the new modules. The latency timings have not changed."

How do I change the settings to incorporate the new ram voltage needed?

I have a Gigabyte AM2 motherboard (ga-ma69g-s3h)
I used to have an option to change the cpu voltage with my old dual core 5000+ cpu.
with this cpu, that BIOS option is gone!
furthermore, I can change the voltage through gigabytes windows utility (easytune 5), but then when I also try to change the multiplier in windows it doesn't change anything and the speed of the cpu remains the same.
I'm stuck at stock voltage and 3.3GHz overclock (which is not bad but since it can get to 3.7ghz I'm missing out).

My computer suddenly started to crash alot almost a week ago and now it crashes sometimes before windows starts loading. After almost a week of testing and reading my theory is that the power supply to the RAM memory has went crazy. However the problem is that the BIOS gives me no option to change RAM voltage (guess it's a warranty thing). So how should I fix this? Is it possible to reset these things or make the computer search the right vaues again?

Because what's strange with my "theory" is how the RAM voltage settings suddenly changed. Can it also be so that the hardware is destroyed? What should I replace then?

My motherboard is a Fujitsu Siemens MS-7450VP.

Hi, my computer (IDell Dimension 5150) was having problems booting, it would lag at the last bar of the BIOS loading screen. After a while, it wouldn't turn on, a flashing amber light which meant that there was a power source but wasn;t reaching it internally, and the suggestion from the manual was to check voltage. I reallly regret it now but I was in a hurry and i was playing around with the voltage switch and changed it from 230 to 115 and I heard a pop noise and now the Green LED light isn't on anymore and computer won't boot. I don't smell anything funny so I hope it's ok. I really need the computer so if you guys could help out, Thanks heaps.

I'm moving to England from America soon, and I'd like to take my computer with me. It's a Dell Inspiron One19, an all-in-one type PC. It doesn't have a voltage switch on the back. However, in the documentation for it on Dell's website, it says "voltage 100-240" ( Does that mean my computer will handle any voltage between 100 and 240 without needing it switched, and that it'll be fine as it is since England's voltage is 230? I've used my laptop in England before without any kind of switch, but I've heard that's only because power supplies for laptops do the switching automatically. Thanks for any help.

Tim mate have you checked out the PSU yet and temps as well see this for checking the PSU

Using HW Info PSU

Download HW Info and pick the right bit version - HWiNFO, HWiNFO32/64 -Download -(copy and paste thissite into the search bar) If you do not need the running information in thesmaller right hand panel close it. In the left hand window click on the + forthe individual device groupings and they will open out to the variouscomponents.

Go on opening out further until you get to the device itself. click on it andit will highlight. In the right hand window there will be a very detaileddescription of that device as in brand, speeds model number etc etc These arevery detailed and are just what is needed for searching for drivers etc.

See my pic for an example - in this I have shown my power but it is a laptopand a desktop will show more details if you scroll down that listing. You will come to a section which lists the rails and for a reference for them see this Power Supply 101: A Reference Of Specifications - Power Supplies Page 2 also gives a good idea of how the Power_Good signak works at pin 8 (grey cable 24 pin socket)
Another way to check the volts is this PSU - Test DC Output Voltage but please do not use an analogue meter as it injects volts - typically 9v into a circuit to test it and doing that to a 5v rail doesn't take a rocket scientist to work out what would happen because all the rails have to be within +/- 5% of the stated value.

How to undo damage??

A:bios change, now can't view monitor to change back

If you remove the battery on the mothernoard
for a minute or two, the BIOS loses it's
current settings and goes back to the defaults
that will work on any system. You'll have to
let it auto-detect hard drives and everything.

My SSD firmware updater needs to do it in DOS. To be recognized in DOS, my HD has to be interfaced temporary in IDE.

I went through all menus and submenus, but I didn't find way to do it in BIOS. Any clue?

A:Asus P5N-MX; how to change from SATA to IDE

[QUOTE=Saintor;1925869] To be recognized in DOS, my HD has to be interfaced temporary in IDE.

It does? I that hard to believe. Where did you get that information?

You can't update the firmware while the drive is running the OS. So you need to run the executable from outside the OS.

One way you can do this by booting from your W7 installation DVD and performing the operations to access the System Recovery Options and then choosing the option to open a DOS prompt (Command Prompt). Then you navigate to the EXE (on the USB stick, I assume) using DOS commands.

System Recovery Options
See if that works for you.

Seriously, Asus has got to have one of the most useless bioses know to man.

Now I'm interested in changing my FAST WRITE AGP speed and my AGP APERTURE speed so i can get the 7800gs 256mb video card running. I heard this bios setting has helped MOST users who are having trouble with this video card!

Now i know ASUS cannot enable fastwrite options or aperture (cuz i researched on google for like 5 hours). I was wondering if it's possible to maybe flash the bios and give it some new settings, using a program like NiBiToR to save the settings.

If anyone has ANY clue on how to fix the BIOS problem i have with AGP settings, i'm all ears .


EDIT: CTRL+F1 does not open hidden settings unfortunatley ...

Dividebyzero found (hell, maybe he wrote it) a story at stating that Asus is making some of their high end 890 motherboards Bulldozer compatible with a bios flash. So I looked up bios revisions for my Formula IV Crosshair, and there she is. You have to hand it to AMD on this one. Unless the Bulldozer is a flop, this is very consumer friendly.

Here is the story DBZ posted:

I am trying to update the BIOS on my ASUS M5A78L-M USB3 Motherboard.

I downloaded the latest updater program from the ASUS website for my motherboard.

When I run the updater, I have to choose an OS. I choose Win8 64bit.

A pop-up informs me that the program will not run on my system & to contact the OS manufacturer!!

How & where do I contact Microsoft about this?

I have tried everything but the onboard BIOS updater will not recognize a USB port with new BIOS as instructed.

It will not recognize the CD/DVD drive either. It recognizes other drives but cannot use there drives for updating the BIOS!

Ok I've had some serious issues with running itunes & my iphone, syncing, writing errors etc.

The guys on the apple forum said to try and update my bios.

So I went to asus' website, found the drivers etc under my particular mobo.

Now I was given two .zip files, I've attached them because once I open the rar/zip files I dont know what to use to then run them with so I can update the mobo?

The first one is listed on their website under the category:


and the other is listed under


I assume I should install both of these since they both deal with the bios?

A:Help with updating Asus Bios

It's been a while since I used Asus products, but as I recall the file beginning with AFUD is a utility used to update the BIOS.

The other would be the BIOS file itself.

You can open both of those zip files with 7-zip, Winzip, or any similar program.

You should look around on the Asus site for instructions on flashing and for the AFUD file specifically.

The BIOS can often be upgraded in several ways--within Windows, outside of Windows, etc.

General advise: BIOS updating is not to be taken lightly. If you have a failure, you will not boot, and will probably have to replace a chip on your motherboard or buy a new board.

So, I wouldn't do it unless you had very good reason to believe it will solve your problems--look around on the Asus site to see if that is true.

I just put together my computer yesterday and for some reason whenever I boot up, I get a message in the POST screen saying that there are no IDE drives attached to my Fastrack controller, and that my BIOS is not installed. I can still run XP, but the flash utility doesn't work when I try to use it. I have a P4C800E-Deluxe motherboard from Asus and running Pentium 4, 3.2ghz cpu. Thank you in advance.

A:Asus BIOS problem

The Fastrack issue is not a problem. Your motherboard has multiple IDE and SATA controllers. These have their own BIOS and thats what you are seeing. Its saying that you have no drives connected to this particular IDE controller which is most likely true. You may be able to disable the Fastrack COntroller altogether if you really want to in the BIOS or on the motherbaord with a jumper, or maybe not you'll need to refer to the motherboard manual.

As for the Flash Utility, what happens with it? Have you tried instaling the latest one from the ASUS website?

Why not consider a fanless MB HS? In combination with a quiet P/S, and perhaps a slower running 120mm case fan, it should be very quiet. Of course, you can also just stick the machine in another room since it's networked.

One of the reasons that I have not flashed the bios is because, no matter how many times I read it, their instructions never seem clear to me. I may be making a mountain out of a mole hill, but I want to be confident that I know what I'm doing. The confusion is on some fairly minor points...They go into detail about creating a floppy and placing the afudos.exe, which is the bios utility, on the floppy, but they never say that the same should be done for the bios itself. Therefore, I don't know whether to put both on the same floppy, or on separate floppies. The instructions also speak of using EZflash, lower on the page, put it isn't clear if this is part of afudos or something else. Here is their instructions, if someone will decipher it for me:

i'm trying to figure which bios i should be using from the asus website. the laptop is asus k52n running windows10 x64 pro. the current bios reads v2.13, dated 08/21/2010.

the asus website has nothing listed for windows 10. there is a choice between "windows 7 32/64" and "others". the listing for windows 7 x64 is described as v2.30.3 which would seem to be a newer version, however it is dated as 07/14/2010 which is older than my current version. the "others" listing is described as v3.12 and dated 11/24/2010, which is definitely more recent than my current version.

i'd appreciate some advice on which to choose. i've been having some bs(od) issues for some time and i'd like to see if a bios change would help. here's a link to the asus driver webpage:

A:Asus A8N-SLI bios update

while not a hard process... it can be dangerous to flash you BIOS version and you run the risk of turning your computer into a nice paperweight.

first off... what is the biggest reason you are looking to update your BIOS version? any problems can probably be solved by other means unless you have proof that you need to flash the cmos. the safest way to flash to a new BIOS version is to use a utility such as awdflash.exe (Award Flash) in command prompt before the computer boots windows. there are ways to flash the BIOS within windows, but it's typically more reliable to perform the operation in command prompt.

for the actual process... you will need the BIOS file (usually a .bin file), and flash utility like awdflash, and a bootable CDROM, USB drive or floppy disk if you have that. i like using FLASHCD to make bootable disks in which both the BIOS file(s) and tools are copied to. basically, you boot from the CDROM and run the flash utility from the prompt. from there you should just need to input the file you want to flash to the CMOS (and if you are using a flash drive or floppy you can make a backup of the original just in case). if all goes well after the file is flashed, remove the media and restart the computer. done.

you should be able to find a more in-depth guide by searching around for A8N-specific stuff... if you need it. good luck...

your question is a bit vague

when installing a new driver it is often the case that you need the original windows 95 or 98 or 98se or millenium disk to fully install the driver
if it asks for the windows disc just insert in cd rom

SO with 1gig Corsair PC3700 DDR Memory in the Asus a7n8x deluxe Mobo, Athlon XP 2400 CPU, with a great thermalright 800 heatsink- I currently have:
CPU Ext Freq: 166Mhz
CPU Freq Multiplier: 13x
Memory Freq: 100%
CPU Interface: Optimal
Resulting Freq: 166Mhz
CPU VCore: 1.750V
this produces 36C/96F temp..
I am new to BIOS/overclocking but I heard that I can take advantage the awesome 1gig memory that I have. Could anyone help me tweak my system.

A:Asus a7n8x BIOS settings PLEASE!!

Take a look at this thread before doing anything else.

Explaining step-by-step how to overclock would easily take a few hours to type without even going extremely indepth of the subject.

Luckily for you, there are hundreds of overclocking resources available for you to read on the web. Do a search from google, or even take a look at TechSpot's own overclocking guide.

A:Asus mobo bios problem

Hello and welcome to Techspot.

I seem to remember some Asus mobo`s were faked, although I can`t remember when this was or what models were affected. whether this is the source of your problem I don`t know.

Run the free Everest programme from HERE and see what details it gives you for your mobo. Then, check the results with the Asus site.

The only other thing I can suggest is you RMA the board.

Regards Howard :wave: :wave:

I finally got my intel i5 4670k and asus z87-a board installed. The current bios is at 1007 and the latest is 1405 should I just run like it is or, would it be of benefit to update? I've done it quite a few times on my other boards with no problems but, I wanted to get some more educated input. Thanks!

A:Bios on asus z87-A update question

I normally would say if it's running OK to leave the BIOS alone. In Haswell's case, it is still having growing pains so an update is recommended. I have used the BIOS Flashback feature to do it. Check your manual for instructions.

I have an ASUS P5E mobo. When I set it all up, I flashed the bios from 0203 to 0502 and a few programs that came with the board ceased to function anymore. The AI suite in particular and also Smart Doctor. I was planning to use AI to O/C but one thing that 0502 had that 0203 didn't was all the increments for uping all the params. Does anybody know if 0501 has those settings, and if AI and SD work in this bios version or should I just go back to 0203.

I recently updated my mobo's bios and with the update I now see this "press F4 to use ACC". I have an AMD Phenom II X4 940 BE CPU. Is there any benefit to using this new function that ASUS is offering with my quad core.

A:Asus mobo bios update

It looks like ACC is a utility for unlocking AMD CPU hidden cores for 'overclocking'.

So if you are into that kind of thing it may be a useful tool.

has anyone with the Asus A8N SLI deluxe updated their bios to the latest version (last i checked it was v1.015)? is it any good?

A:Asus A8N SLI Deluxe Bios Updates

Hello pkroks.

I can`t answer you question, but would like to offer you some advice.

If you system is running ok, I don`t advise you to update your bios.

The updating of a bios should not be done, unless there is a very good reason to do so.

A:RAID and ASUS HDD not recognised in Win XP, but is on bios. please help

Boot up windows and go to Control Panel -> Administrative Tools -> Computer Management and find the Disk management tab on the lower left. Click it and the HDD should be there. The reason it hasn't been recognised by windows is that it hasn't been formatted. Use this tab to format the drive (might take awhile).

I was poking round the bios earlier and I came across two entries
in Advanced -> Chipset these are System Acceleration Mode
enabled/disabled currently disabled and also VideoMemoryMode
UC/USWC currently UC can anyone shed any light on what these do? System Accelration mode sounds kinda groovy! as always any help is appreciated.

A:Asus A7A266-E bios settings?

The system acceleration mode in your mainboard is probably an option to enable certain aggressive settings for memory timings, etc...

Try enabling it seeing if your system is still stable. I have an ASUS A7V266-E & there's an option called Performance level ( Normal / Optimal ). If I select Optimal, RAM Timings are set to CAS2, etc...

If you start having random lock ups, I suggest setting it back to default.

Is there anything mentionned in your BIOS manual about it ? I don't have an A7A266 so i'm only guessing here.

As for the VideoMemoryMode, it's common to ASUS mainboards. I'm not sure if they're the only ones to have it. Could anyone confirm if they have this option with a non ASUS mainboard ?

Here's a little explanation I found on the subject.

Video Memory Cache Mode (ASUS mainboards)

By definition, video memory is excluded from being cacheable since otherwise the large data chunks would fill up the L2 chache of the CPU immediately. When the CPU calculates 3D, that is, floating point operations, every data point needs to be written to the local frame buffer (on board graphics memory). Unfortunately, the CPU can either write or calculate, therefore each write cycle interrupts the floating point operations, in simple terms, the FPU unit can only work at half speed. Intel were the first to incorporate 8, so called, write combine buffers on the Pentium II, which was one of the reasons why the PII had a superior 3D performance compared to the original K6, at least at low resolutions. The reason is simple, instead of single bit writes, the data are temporarily stored in write combine buffers and released in burst mode. Therefore, depending on the size of the WC-buffers, FPU calculations are interrupted much less frequently, in other words, the graphics performance of the CPU is almost doubled.

Graphics data inherently feature high locality, therefore there is no problem pipelining these data. With the CXT revision of the K6-2 and the K6-III, AMD added two write combine buffers and, as we were the first to post, proper addressing of these buffers via software would boost graphics performance by as much as 30% within the identical hardware configuration. The Athlon family has four aggressively programmed 64 bit WC buffers buffers that can be placed over the local frame buffers for both data and hardware acceleration. Compared to the PII / III WC buffers, the novelty is being capable of executing out of order writes in ascending and descending order and thus taking write combining to a new level. This way the efficacy of the 3D floating point operations can almost be doubled. Available settings in the ASUS A7V BIOS are either uncached (UC) or uncached speculative write combining (USWC). Needless to say that USWC needs to be supported by both graphics adapter hardware and drivers but if it works, it is one sweet feature.

Hey guys,

I recently just built my first pc with a Asus Sabertooth x58 motherboard. When I checked the Bios it was version 0702; however, I cannot find that version anywhere on the web. Not even Asus's website. Any idea why that is? Also should I upgrade to their new BIOS v0802?

Should you upgrade? If you aren't having any problems with the BIOS now, I would not bother. You may if you wish but there is some risk involved.

In one topic I asked how to Overclock. I learned it , and know more about it.
But now my problems is my BIOS. I dont know how to use it. That isnt classic....
I dont have to edit time or HDD slave, not to do anything harder !

My BIOS is same as

My motherboard is ASUS P8H61-M LX2 and it have latest ASUS BIOS (EFI BIOS Utility- EZ mode , I attached one link here to see).

My questions are :
1. Can I back normal BIOS like one old ?
2. How to use that ? Is there any tutorial for this ?

That is all for now.
Thanks in advance.

I have an "old" Asus Cusl2-c MB with the latest Bios available from Asus. I put my brand new 200 GB WD drive in as a master on the Primary IDE bus and auto-detect it in the bios & it comes up as 8,455 MB. With my slightly older ABit MB, it at least comes up as 138GB, which I'd expect with the Asus. Is there any way around this - can I manually insert the HD parameters. If I have to get a PCI HD controller as suggested by WD, will the Read/write times be as fast as if directly connected. The board supports DMA mode5. Any Help highly welcome.

Asus X401u Laptop Auto Repair Loop - HELP
My grandson Asus laptop screen was not working. So I changed it. I can see that it works great. Now here is my problem.
His Asus Laptop with Windows 8 running on it. Now every time it starts up it displays the windows logo and a minutes later it displays Asus logo with the message "Preparing automatic repair" and a boot diagnostic, followed by a black screen, then it starts all over again.
I can use the escape key at startup and the F2 (delete key does the same as F2) but honestly I have no I idea what to do next.
There is no CD drive and I asked if he has a copy/backup of Windows 8 in a SD card for flash drive, in which I don't have one.
Someone please help me on this.

A:Asus X401u in a bios loop

You say your grandson's ASUS X401u laptop wasn't working, so you changed it.
What exactly do you mean when you say you "changed it"?

You say that ASUS X401u laptop is running Windows 8.
According to its support site, it comes with one of these Windows versions:
Windows 7 Ultimate
Windows 7 Professional
Windows 7 Home Premium
Windows 7 Home Basic


I personally have never used Windows 8, so someone else who has will need to address any issues with it.

You also might want to make use of its support site and FAQ section.
