I woke up this morning to find my monitor showing that it had no signal and the computer not responding. I reset it but it would not POST. I reset it several more times and it finally booted up and into Vista only to immediately give me a black screen again. This time I powered down a couple of times and it finally booted up and stayed booted. I left for work and when I got back this afternoon once again my monitor had no signal. I have not recently added any new hardware. I have tried unplugging everything - all my drives, and my memory and the motherboard doesn't even give me a beep code. I have also cleared the CMOS. Please help me. My hardware: AsRock Dual SATAII 939 motherboard w/ AM2 card X2 5600 CPU 2 GB RAM Seagate 300GB Barracuda Geforce 7900GS
Update: After clearing CMOS AGAIN and this time taking the battery out (per AsRock tech support instructions) I still had no luck. For the hell of it I took out my AM2 adapter card and reseated it. The computer POSTed and I logged into Vista. About 30 seconds later the monitor lost signal again and wouldn't come back on. I could still see hard drive activity for a minute or so after that though. I then reset the computer and still got no signal to my monitor. I left it on and a minute later heard the little Windows Vista sounds that play when your computer starts up. So obviously the computer IS POSTing but for some reason my monitor will not hold the signal.
it seems funny but sometimes not just the internal parts are causing problems a damaged ps2 keyboard cable can cause that crashes too take out all the monitor, mouse etc. and just plug the power cord only then try to work it if it does, %80 no serious problems are available for you if the gpu has a problem it won't open anyway just the video card tests will pass and immediate shutdown will seen
by the way to get full performance from your cpu throw the mobo into your office trash can asrock, biostar etc like producers can't make performing cards they are just building the card to be card, nothing more i recommend you epox or asus if you consider changing
