Computer Freezes on bootup/sometimes doesn't post help!
I basically built this computer about 3 months ago. after couple of months I start to notice after I start the computer my tower comes on but no display. I restart the computer and it post but then I get an overclocking failed error. I tried installing vista twice and now I'm using window 7. Its starting to freeze up after the post and when you get the glowing windows flag. But mostly when I first turn it on I get no display but tower fans and all that good stuff is on. I'm tried to reset cmos multi times. My comp is not overclock its on stock clock. I just can't figure out whats the problem, what I do notice also is if my computer is on and loaded I'll restart about 2-3 times to see what it does and on the third restart that when it give me the overclock failed/or doesn't post. I'm sorry if I sound confusing I'm doing my best to explain. My setup is below also windows is fulled updated and bios is most current.
