Then I restart it and it works fine. I only get the blue screen on cold starts and always works the second time. I ran the memtest so ram seems to be fine, I'm suspecting the graphics cards. I've updated the drivers but still nothing. And when I run the driver verifier it seems to narrow it down to 0x000000c4. The only problem with this is that it doesn't allow me to run safe mode and so I'm forced to a system restore.
I think those who can help would want to know whether you built this yourself, and what beeps you hear, among other things (read),
Though you tested RAM, i would try taking all the modules out, and then trying one at a time to see if it will boot. Also, remove everything you can and try to boot. And make sure all is securely seated in any case.
