Win7 x64 Pro freezes randomly

memtest finished two passes, no problems. BIOS settings haven't been touched for linux, plus I updated the BIOS and set everything to reccomended settings hoping it would fix the freezing but nothing.
Had read on a few places that updating ATI drivers fixed freezes for some people but about 20 minutes after updating (and restarting) to the newest ATI driver it happened again

Anyone still effected by the freezing problems please reply or click the button on the first post on the official microsoft forums, hopefully if theres enough replys we should get somewhere with fixing it
