Current specs: AMD Phenom 9850, Geforce GTX 460v2, 1 stick 2gb DDR2 crucial ram, 2tb seagate HDD, 120gb verbatim SSD, ASUS M3A78-CM. I've had BSOD problems before, but found it was due to a fault stick of ram. I hope it's not this other stick of ram, then I would have to buy more ram now. My computer is always running cool and never overheats. I clean it regularly too. Also it boots up normally when I let it cool down.
