Windows 7: Corrupted BIOS and BSOD

Sirke25 · 17 Nov 2012

Hi everyone. I have a problem with my laptop (HP Pavilion dv6-2110sm). Recently my laptop freezed and caps lock and num lock started blinking two times... This never happend before so I googled it. It seems that my BIOS is corrupted. I don't know much about computers so I searched what does "corrupted BIOS" mean. There were a lot of solutions and I tried most of them but none of them worked.

I tried the trick with holding the windows key and B and then power button but nothing happens. It restarts automatically and nothing happens. I tried pulling out RAM slots and returning them back but that didn't work either... So I'm out of options. Also I forgot to say that I can't work on my laptop because after I reboot, it freezes and I can't do anything. Caps and num lock just blink and I have to force shut down.

Another thing, sometimes blue screen of death appears and it looks like this:

A problem has been detected and Windows has been shut down to prevent damage to your computer.

BAD_POOL_HEADER

Error 0x00000019

That's all, please reply soon. Thank you in advance!

Could you please upload a .NFO file:

Start

> Type: msinfo32 > File, Save

It will provide lots of useful information about your hardware and software configurations, and also will allow me to point you to the correct drivers which need updating.

How often do you get this corrupted BIOS message? You may need to get a new motherboard.

Test your RAM - Test with Memtest86+ for 5-6 passes. Test sticks and slots following tutorial.

Try resetting CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS.
Take note of the SATA controller setting first.

Check your PC Support Downloads webpage for a BIOS update. If none you may need to reflash your BIOS chip with the latest if the problem isn't resolved working with Harry on the suspect drivers or by the memtest. You should wait for our help to do this however.

Thanks for the prompt replies. EDIT: Nevermind, I've found the drivers, will install them now.

I can't seem to upload the .nfo file because it has a size limit of 500kb and the file is ~1.2MB. I can't find the DAMN NFO viewer file in regedit for some reason. Can't find the HKEY_CURRENT_USERSoftwareDAMNDAMN NFO ViewerMaxFileSizeKb to 0.

I didn't get the BIOS message until today, it just started happening. The computer freezes after some time, and caps/num lock start to blink slowly. Sometimes it would happen as I started Firefox. Thanks for your help!

I can't extract the zip with the drivers in C, it says access denied. It's my brother's laptop and I don't know what's the thing with administrator privileges on it, but his account is administrator. It's all messed up, it froze again after maybe 20 minutes after last reboot.

Why are going into registry? DO NOT change any settings or delete any keys within the registry, as it will only cause further problems and can result in a unbootable computer.

Use:

http://www.sevenforums.com/crashes-d...tructions.html

Use the "Grab All" button, you can delete the dump files from the folder it creates as you have already uploaded them to the thread.

Where are you downloading the drivers from? Are you sure you downloading the correct driver for your OS and for the model of the required hardware component?

Upload your .NFO file, as explained above, and then we can look at providing you with other instructions.

Because, as I've said, the nfo viewer has a 500kb limit and I can't upload the file (1.2MB) without removing the limit in the registry. It says invalid file on the forums as I try to attach it. The line is at the end of this page:

DAMN NFO Viewer

And this is where I found the drivers:

Drivers for Atheros AR9285 and Windows 7

I'm supposed to extract them in C but it says "access denied" for some reason. There's no .exe file for them, they're self extracting I guess.

I'm downloading the SF Diagnostic Tool now btw. Thanks.

Go to Control Panel>User Accounts and set up a new Admin-level User account to see if you can perform these functions. If so your User Account is corrupted. One way to resolve this is to move everything over to the new Account and delete the old one.

Otherwise try running SFC -SCANNOW Command

If problems persist run a Repair Install as a last resort before running Factory Recovery, or better yet get a Clean Reinstall - Factory OEM Windows 7 which is what most tech enthusiasts do to avoid the HP preinstalled crapware that throttles and corrupts Windows 7.

If you have it, uninstall Avast and replace with Microsoft Security Essentials,
run a full scan.

Here it is.

**x BlueRobot** · 18 Nov 2012

Uninstall Avast:

Code:

Start Menu\Programs\avast! Free Antivirus

You can install Microsoft Security Essentials and TDSSKiller:

I see that you have Malwarebytes already installed; run full scans with both these programs, however not at the same time.

Uninstall RegCure Pro:

Code:

Start Menu\Programs\ParetoLogic\RegCure Pro

These third-party programs usually cause problems for your system, and many are usually hidden malware or spyware programs.

Uninstall IObit Malware Fighter:

Code:

Start Menu\Programs\IObit Malware Fighter

This provides real-time protection like Avast, and therefore having both running will cause conflicts and produce problems in your system.

What is this program?

Code:

Start Menu\Programs\TELL ME MORE SI PLUS

There is many entries for this program within your .NFO file, are you aware of this program? What does it do?

Have you followed Greg's suggestion, and please post back your results.

The driver link is not working for some reason, have you installed all the Important and Optional updates for Windows 7?

I don't think you have installed Service Pack 1, why is this?

Code:

OS Name:                   Microsoft Windows 7 Home Premium 
OS Version:                6.1.7600 N/A Build 7600

Update Atheros AR9285 802.11b/g/n WiFi Adapter:

Code:
