BSOD after computer has been up for some time

[eaflores]

Currently:
Windows 7 Ultimate x64
Not the original OS of the system
Full Retail
Age of the computer is about 8 months
Age of current installation (at the time of posting) is about 7 hours.


Hello there I have been getting BSOD for about 5 days or so.
I had Windows 7 x64 professional on the computer.

Today I did a "ultra clean install" to Windows 7 x64 Ultimate
I did a DISKPART -> clean all then installed this version of windows hoping that my problem would have been fixed. I have receice about 3 or 4 BSOD's since this installation.

All my drivers seem to be up to date (manually checked all drivers from device manager).

All help is greatly appreciated.
Thank You.

I hope I successfully attached the zip file as instructed by the site.

I have also received numerous "has stopped working messages" including windows explorer before and after installing the current OS.

New info:

The computer has been on for about 1 hour since I made this post and now the message Windows Explorer ahs stopped working comes up when I try to search for programs and files or by trying to click on Windows Update among other things.

Another BSOD after Windows Explorer stopped working.

You have AVG installed, is that correct? At least to test, uninstall it and install MSE (Microsoft Security Essentials) instead.
Microsoft Security Essentials - Free Antivirus for Windows
