Hi experts, For the last 2 months I've been experiencing a very regular BSOD on my PC. BSODs occur only on the wake-up or on the start or shortly (up to 5 minutes) after both start/wake-up; sometimes I have to reboot 15-20 times to get the system work.

I even have tried to keep my computer always on for 3 days and it never failled. The BSOD started on my Windows Vista Home Edition; I have installed the genuine Windows 7 professional (French version) but the problem continues. Thank you for your help.
