BSOD mostly while downloading torrents or not using laptop for while

Great. Here i go. But thanks a lot to you all, i am delighted irrespective of if i manage to sort out my issues or not. If you happen to drop by in my place, i owe you all a drink

Cheers!

Hey Guys,
Well i guess, i need to say thank you all. It might be too early but looks like it's sorted. I am downloading a torrent file but no effect thus far. If it would have been yesterday, i might have had a BSOD already. KoolKat, you the man. Thank you brother for all the support. Arch, cmon man just one for the road, forget your oath . And britton with the US flag in your profile , thanks for that advice too.

I did most of the things that Arch and KoolKat had suggested. I am starting up with only security essential, uninstalled everything u have asked and re-installed atheros driver. Installing driver was tricky though because the one i downloaded from your link didn't have the exe. file so i couldn't run the damn thing. But lucky enough someone in this forum had given out the other down link in some other post so that saved my day. I did complete scan with both EOD, security essential and also used Kaspersky to scan rootkit, nothing turned up. Maybe it was the drive caused BSOD and i suspect the atheros. Nonetheless, i can say i am free from BSOD for now (touchwood) and many thanks to you all.

Hey Guys,
Great news. Two days of continuous torrent downloading and no BSOD. Much appreciated. Arc, well don't judge the book by its cover ;-). Britton, Cheers bud!
