turn on system, hard drive light flickers like booting, but no display whatsoever
Asus P4C800 - 3.0GHZ Intel processor
Not a new build - ran for 5 years fine - gave to my daughter, and they left it running for a year without shutting it down, when they did, it won't boot now. How do I test the motherboard without replacing it?
It is either graphic card or monitor cable or monitor itself. If motherboard has video output try that. Or try a different graphic card. Try monitor on different computer. Try other monitor signal cable...
I've already tried a different Video Card (mobo has no onboard video), two different monitors, and two different cables. Same results. Thanks for verifying I had the right thoughts to begin with ... any other thoughts??
