This is getting expensive and complicated for me. Complicated I can understand, because I'm trying to save money building my own system, something I've always done before. Expensive because this is the second time I've run into this problem and Newegg has refused to refund my first RMA.
Details now: I built the following system. With a new monitor, I was able to get Win7 loaded up and the system worked fine for all of one day. The next morning, it was seemingly dead, although nothing had changed. Further examination showed that
1) The Windows music still played and the front panel lights blinked.
2) But the output from the graphics card output-1 was producing no signal with neither the new Acer monitor nor with my Panasonic TV.
3) The output from the onboard IGP graphics VGA port was equally producing no signal.
The full system that I built is detailed below. Jiggering things around by extracting one piece at a time, replacing all cables, resetting the CMOS, etc., got me nowhere. Still no signal. I regret, though, that I never tried the second graphics card monitor output port.
I RMAed the motherboard to Newegg for a refund and ordered an exact replacement so I could pick it up and rebuild things as quickly as possible. I put everything back together, exactly the same as before. It booted up fine, I got monitor signal the first time, and everything was fine and dandy. For almost a week...
And then the same exact thing happened. I woke up yesterday, turned on the system, and got the No Signal message on the monitor. Switching to the IGP got me the same. Windows music still played. Leaving the system on for a few hours so it could warm up and then trying again didn't help. I haven't tried it on my TV set and haven't pulled any parts, but I strongly, strongly suspect that I'm encountering the same problem and that it's not the motherboard itself, although the motherboard might have been fried by whatever is causing the problem.
Dicking around with the cables, though, I discovered that I COULD get signal from the second monitor port on the graphics card. This got me back into the system last night. Going to the Win7 Screen Resolution got me a screen that I think is different from the one I used to get. When I click Detect, it shows the monitor on port 1 just fine, but a text message saying "Another Display Was Not Detected." That's true -- there's not another display hooked up -- but that message doesn't seem familiar.
Here's a provisional list of possible problems I've considered. I need your feedback on this before I start hassling Newegg:
1. The Power Supply may be flaky.
2. The monitor may be flaky.
3. The motherboard may have a basic design flaw making bother motherboards flake out the same way (seems unlikely but possible).
4. The graphics card is flaky and is, in its own time, frying the circuitry on the motherboard associated with conveying graphic signals.
I'm leaning towards #4, that there's something flaky but intermittent about the graphics card that is damaging the motherboard. It would explain why a new, identical motherboard worked for a while but experienced the same problem. If it was just isolated to the graphics card, if that was all I had to replace, then why would the onboard IGP monitor port not work anymore, even when the card is yanked?
My plan right now, and it's an ugly one, is to disassemble everything and RMA it back to Newegg.
To complicate matters... The first motherboard that I RMAed (identical to this one) had the refund REFUSED because, as they claimed, the CPU socket pins were bent. Well, it's not impossible I bent some pins removing the CPU chip, but a badly installed CPU (correct me if I'm wrong) with bent pins would not have worked at all. And the CPU worked fine in this motherboard for a week, before it croaked the same way. I would have to be spectacularly clumsy in installing the CPU both times to be experiencing the same problem, therefore I don't believe this is what is causing this problem. And I'm going to fight Newegg on this.
