BSOD before & after clean install of W7 "DRIVER_IRQL_NOT_LESS_OR_EQUAL

Had intermittent BSOD for past two years while using Vista. Just re-formatted the hdd and clean installed Windows 7 Pro N 64-bit. Still getting the same BSOD that typically occurs if the computer is left on for a few hours.

Dell Studio 1535
4GB Ram
Intel Core 2 Duo

SF Zip file attached.

I appreciate your help resolving my problem.

Hopefully there's not much to do here.

STOP 0x000000D1: DRIVER_IRQL_NOT_LESS_OR_EQUAL
Usual causes: Device driver

First look for a update on your BIOS version, current ones are of 2008. (must)

Code:

BIOS Version/Date	Dell Inc. A05, 7/30/2008

Thank you for your help. Just tried to update the BIOS to A06 version but ran into the following error "The BIOS update could not be performed because a valid ROM image file could not be found"

Any ideas why this is?

Can you give me the link to your BIOS?

Don't know how to do that. Can you tell me how?

Check for an update for your VGA, you'll probably get it from windows update - optional list / or the manufacturers website.

Look for an update on your sound device drivers too..

Run disk check to make sure your hard drive is good:
Disk Check

Run the system file checker to repair any damaged windows files:
SFC /SCANNOW Command - System File Checker

Run a full scan with your MSE antivirus & run a additional malware scan with Malware bytes free:
Malwarebytes : Malwarebytes Anti-Malware removes malware including viruses, spyware, worms and trojans, plus it protects your computer

Let us know the results and further crashes if any :)

Check Disk, System File Checker and Virus Scan came back with no bad results.

Version A06 is available but I can't update via windows 7, says it can't find the rom file. I have tried to create a bootable USB drive to update via dos but I can't download the bios forum.com file since it seems to no longer be hosted.

3 years old. I will clear dust if any.
