PC failed to boot with a dark screen resulted
AMD Athlon64 3000
Asus A8N-VM motherboard with on board vedio card
Gigabyte NX66 256 DDR2 vedio card
The PC failed to start. The CPU fan was turning and so was the HD. The HD LED light continued to glow. I heard the beep sound but nothing displayed on the LCD monitor screen.
This box has another HD running WinXP. I tried it with the same result.
This problem happened recently. Previously I got the screen back by turning off/on the LCD monitor. But this time it did not work.
Please advise where shall I start to check. TIA
