BSOD!!!

I'm getting the BSOD fairly often (5x today - it's killing me, I've lost alot of work so far). Please let me know if yall need more information. Thanks a ton in advance for your help.

I'm on about a 1 year old Lenovo Ideapad U330 that has been back and forth to lenovo for a couple of hardware issues (keyboard, bluetooth adapter, etc.) I'm running windows 7 ultimate 32-bit. I recently formatted my drive and installed windows vista first, then upgraded to windows 7 with my upgrade cd, although I did choose the "complete install" option, so it may technically not be an "upgrade". Hopefully this is enough info, I've never had the BSOD before. Thanks again

Complete your system specs and take a look at this tutorial..

then get back to us.

I wonder if AVG is the cause. Please remove it with this tool:http://download.avg.com/filedir/util...avgremover.exe

Replace it with Microsoft Security Essentials: http://www.microsoft.com/security_essentials

Also, please enable driver verifier: Using Driver Verifier to identify issues with Drivers
