I have a similar problem as you Akrian, save I never get a blue screen, my system just hangs at random points in time mostly during idle though, has happened a few times during games though. One thing different than what I read in your posts (which are kinda hard to go through, no formating in them...) is my usb mouse loses power (only usb device). I know it isn't my video as the card runs perfect in any other system as well as your's, I know it's not my overclock as it hasn't changed since day one and does it at stock settings plus does it with my other 3 chips, I know it's not bios as I replaced both chips in order to fix another problem (some what fix it at least), not the ram nor slots as same problems with no matter what ram or how much/little or slot I put them in, it boils down to me believing my board is dying. Problem is with it dying I have no way to RMA it, so gotta live it locking up until AM3 is released.
