I've had this problem for a while now. I have absolutely no idea what's causing it. At first it was occasional, then it increased in frequency, and now it's all it does. I'm at a point where I can't even use my home computer.
When I start my pc, everything sounds like it's working fine. All fans run, video card fires up, no strange noises. But nothing ever comes up on my monitor.
It stays black with a sign in the upper left corner that flashes between Analog and Digital. It does that for a few seconds, then it goes completely black and the power button flashes, like it's in sleep mode.
I recently replaced my motherboard with a new one (same board, just new), also replaced my processor last night. Still the same issue.
Here's my list of hardware, running Windows Vista 32-bit
Motherboard - Asus M2A-VM AM2 (new)
Processor - AMD Athlon 64 x2 (new)
Video Card - nVidia GeForce 9800 GX2
Memory - 2x G Skill 240 Pin DDR2 2gb (4gb total)
Monitor - Samsung 22' monitor
Any help on this issue would be much appreciated. I've been struggling with it for months, it would be nice to not think about it anymore lol
