My computer will not post. Twice over the last few months, it has booted and given me a message saying my BIOS were corrupt, but after eltting it sit this error went away. It also began freezing a couple of months ago. Now, when i turn it on nothing happens, the fans, harddrives, cd drives and everything power up, but i get no beep and no POST. I have tried swapping out every part except the cpu and mobo, to no avail. It started up and booted once, but once i shut it off it died again. I havn't done any overclocking and the board is not very old, what could be possible causes of this? there is also a very faint white "cloud" ont he bottom of the board surrounding the north and south bridge, and over heating had been an issue. Is this a case of my mothboard just... dieing? after 6 months and no abuse?could it be my cpu? AMD 64 x2 4200 asus m2v 2 512mb super talent hyper type-r 550w psu xfx 7600 gt I assume the motherboard just died but i cant really afford a newone right now, especially if the cpu is shot. any advice would be rgeatly appreciated.
