The cpu, ram, hdd, and OS are recent upgrades. Since I upgraded my computer does not boot up fully when I turn the power switch on. The lights and fans come on and I can even hear the noise that windows make at the login page through my speakers, but I get no video.
I then hit the reset button and it boots up fine, no other problems, until I shut it down and try to restart it again. I would think that the problem is the video card, but the video card worked fine until I put in the new cpu, ram, OS and hdd.
thanks for the replies guys. I have already done memtest 86+ with no errors. I dont have another system to try the gpu in. I think I will pull the video card and boot with integrated video and see if that helps.
Pulling the GPU and running off the internal will help and I suspect the reason it will hep is less load on the PSU. I often see this (system unstable on cold boot, runs fine on warm boot) when the PSU is undersized or getting ready to die.
