General BSOD After Reformat, Error 0.0000000a?

At first, I had a failing processor, and I managed to replace it, then Ireformatted my system.But then, I was receiving multiple BSODs after that, brought it to a computer store downtown, and they determined the problem as a corrupt install of Windows 7, and proceeded to reformat it themselves. I assume they also updated all the drivers, but I'm not sure. And just now, my computer won't wake up after sleeping, I've received a BSOD in the middle of playing TF2, started up the computer again, another BSOD while starting TF2, start up again, about to google a few things, and another BSOD.Windows 7 64 bit, originally Windows 7 64bit as well, this is the 2nd reformat.The hardware itself is about 1.5 years old, except a replacement processor, which is about 1 or 2 months old.
