Continuous BSOD every 20 min

Where are the screenshots ?

instead of screenshot upload the minidump folder. screenshot won't help in case of BSOD.

I used imgur but

Sam: Apologies can u tell me how to do so

check if a minidump folder exist inside the Windows directory. Either zip the minidump folder, upload it to some file sharing site and post the link here or you may use WhoCrashed to analyze the minidump files (it'll do it easily) and check what it shows.

Hey , sam do you know how to retrieve the Dump file/folder if the windows is getting crashed at startup , I.E , right after it Windows7 animation , it displays a BSOD , for a flick of second. Everytime.
Its happening in safe mode too. I am not considering the option to reinstall at the moment , if there is an alternative to it.

check for overheating, bad sectors on HDD and bad memory modules and if possible tell your friend to reinstall a fresh copy ( fromat OS partition and install/restore ) of the OS.

@sam: Ill do it and check get back dude
@topgear: 1. No Overheating
2. & 3. ll check it
4. I installed him fresh copy of Windows, after that it is worse
