I have and asus a8v deluxe with athlon64 3200+ and 2x512 ram installed. I tried to add an additional 1gig stick, but after the computer wouldn't boot "due to cpu overclocking" i realized my mobo doesnt support the configuration i tried (2x512 + 1gig). I pulled it out and the computer booted fine, but now 2-3 seconds into windows the whole thing freezes and/or the whole screen goes to those plaid-patterny artifacts. I can only boot into safe now. I have no idea where the "overclocking" came from; I have never attempted to overclock the cpu. I didn't do ANYTHING except pop the new ram in, boot unsuccesfully, and pull it out again. I very confused and pissed off because i want to get back to playing bioshock and i hate spending money, so please help!
