Hi. My PC sometimes POST's and boots and other times it doesn't. And when it does get to desktop the computer freezes. The PC is a new build (3 weeks old) and for the past 2 weeks, the computer has only worked when restarted quite a few times. And it's gotten worse over the past week where sometimes it POSTS and sometimes it doesn't and after lots of restarts it reaches the desktop and then freezes. I also sometimes get the BSOD which says "A clock interrupt was not received on a secondary processor within the allocated time interval", and having googled this it really hasn't enlightened any further to what I already think it might be. Please help. Thanks. Here are my computer specs: CPU: i7 920 @ stock speed Motherboard: XFX X58i GPU: XFX ATI 4890 Memory: some generic Micron, 3x1gb, here it is: MT8JTF12864AZ-1G1 PSU: Corsair 650w
