Error 0xc0000005 is being reported by Windows as an error in main memory. Have you run memtest86 recently? Is your RAM overclocked? Is it overheating?

Unfortunately it can also be caused by other things, including errors in a current version of the drivers, as you've already concluded.

did chkdsk and found some bad files to do with AMD it looked like stuff ran by rather fast and I didnt think to use pause so I could read it all but there was many files. No PC nore memory ever been OC everything is at defualt in bios, never had much luck OCing a AMD for some reason and the PC cranks out some nice work units when it works right. Think I will reinstall Win 7 see what happens. And no heat issues the pc runs much cooler then its Intel/nVida counterpart

[frsaylor]

Thx Bruce for narrowing the search, it was a stick of ram gone bad memtest found it right off, Thx. Now running on the good stick and all is ok so far. First stick of Corsair ram I EVER had a problem with. RMA approved ")

Now that we do know what it is, I'll change the topic title.
