I recently purchased and installed an ASUS M5A99FX PRO R2.0 and a new CPU cooler (specs below). I installed a fresh copy of Windows 7 (same hard drive it was on previously).
My computer will now randomly crash to a blue screen from windows.
There is no discernible pattern to the crashes. The computer will crash both when it is idling and when it is under a load. The computer will sometimes crash a few seconds after I log into the desktop and sometimes I can use it for about ten or fifteen minutes before it crashes.
None of the fans spin up prior to a crash (so I don't think its getting too hot).
I have installed the chipset drivers from the motherboard cd and the latest Radeon drivers from AMD's website.
I fiddled with the BIOS settings (meaning I turned off pretty much all the extra features on the board) after finding the instability but to no avail.
I have not as yet adjusted any of the CPU settings.
I am really at a loss folks, any ideas and/or pieces of advice are most welcome!
