No, I have a dell stock motherboard
. You see, i had a studio xps 435mt. I changed the PSU to a 750, the GPU to a 460 gtx oc'ed, and hard drive to (1) 1.5 TB and (2) 500 GB. I also changed the case to an antec 900. However, the two things I havent upgraded yet are the motherboard and the heatsink (i dont plan on upgrading the processor for a long time). Ive never had a problem like this before. Thanks for your replies. Any other suggestions?
