Windows 7: Random BSOD - ntoskrnl.exe+80640

10 Dec 2013   #1

Windows 7 Ultimate x64
Random BSOD - ntoskrnl.exe+80640

I have received countless bsods...I have tried changing the HDD and the ram, and the issue still occurs. All drivers should be up to date, as well as bios.

I have run memtest86 for several passes for each stick of ram, along with both at the same time. I have tried placing them in different slots, to still no avail.

The bsods are extremely random:
-On start up
-On shutdown
-When opening a browser
-When clicking start
-After running (while being used) for hours straight
-After idling for hours straight

I have never had such issues with any machine, and while I have fixed several computers, it's clearly time to ask the professionals. Any help is appreciated!

My only theory left is the bios default settings are OC or under clocking the ram or CPU, but I haven't a clue at this point.

The BIOS is up to date.
Version 5001 dated 2010/04/14 is the latest, and it is installed.

But not the drivers. Display and network are failing that is vissible, so checked for these two ......

Update your ATI/AMD display driver to the latest WHQL.
You can get it from the link in our forum, Latest AMD Catalyst Video Driver for Windows 7, or you may go to AMD Graphics Driver and Software and opt for Automatically Detect and Install the appropriate driver for your card.

During installation, you may opt for advanced installation, and install the display driver only, not the Catalyst Control Center.

Update the network driver from Realtek .... get the Win7 and WinServer 2008 R2 Auto Installation Program dated 2013/11/26.

Are you overclocking? As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings.

Check if the Power Supply Unit (PSU) supplying adequate power to the computer or not.
eXtreme Power Supply Calculator
Also let us know the wattage of the PSU.

Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy. Alternatively, you can publish a Speccy snapshot too: Speccy - Publish Snapshot of your System Specs .

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Let us know the results.
