Yesterday my son's machine refused to boot. Case fans will spin for a few seconds, then nothing. CPU fan does not start. Power Supply seemed to check out ok, although PS tester had no light on the -5 volt. (All others steady green)
Removed HD 7870 video card and connected to onboard DVI port. Still no luck. Any suggestions? Hate like heck to replace mobo or cpu, cost is definitely an issue. Thanks in advance.
