|I'm not very technical minded, but here's my set up (copy-pasta from Newegg, where I bought them):|
Motherboard: GIGABYTE GA-M57SLI-S4
CPU: AMD Athlon 64 X2 5200+
PSU: ENERMAX Liberty ELT500AWT 500W ATX12V SLI Certified
Graphics card: EVGA 256-P2-N624-AR GeForce 7900GS 256MB x2 (in SLI)
I've had my set up for over 2 years, no problems. The only real change recently was adding another graphics card, which I bought used two months ago. Even then, I gamed a bit for a month and nothing happened. It's only this week that my comp's been booting strangely.
I turn on my computer and the fans spin, but nothing after that, no POST or anything. At first, I thought it was the used graphics card that was doing something, so I removed that, cleared CMOS... after hitting the reset button a few times, it boots through to Windows. I thought the problem was solved, and turned it off for the night.
The next morning, it does the same exact thing: fans turn on but black screen. I notice then that my DVD drive lights were blinking over and over. So I remove all my optical drives, clear CMOS, and after hitting the reset button a few times, it boots through. Turn it off for the night.
Does the same exact thing again today. I'm at wit's end. I have to go through this ritual of clearing CMOS and hitting the reset button a few times to get my comp to boot properly. Sometimes though, the reset button and even the power button fail to respond.
I notice that I can restart my comp but when I turn it off and turn it back on, my problem happens. I also notice that once I boot through, my computer seems to work fine (I'm posting this from my bad comp)... getting it to turn on and boot properly seems like the only problem.
1) Is this problem symptomatic of a bad PSU?
2) Is clearing CMOS as a temp fix indicative of anything else? Am I causing any other problems from repeatedly doing this?
3) If I decide to get a new PSU, what exactly should look for?
Any help would be greatly appreciated...
