Hi. I'm hoping someone can help me. I have an ASUS P4S8X MOBO, with 1.5GB of DDR, and an ATI Radeon 9600 Pro AGP8X 256MB video card. There was a power outage here that seemed to kill my HD (80GB WD). I came home and found the system in a continual loop of rebooting itself, i.e. it would go through the steps to boot, find an issue with one of the booting files, and restart again. I pulled the HD and found the boot record was messed up and the partition was screwed. So, I recovered as many files as I could on my other computer and put the HD back into the case. Now, I try to power on, and nothing happens. No fans, no hard drive motion, no nothing except to led's Here's the details on my problem. This MOBO has two LEDS, one green to indicate power to the board and one red that indicates when an incompatible video card (3.3V vs 1.5V) is in the AGP slot. Both the green and red led's are lit, and the manual says with the red led on, the MOBO won't power up. I haven't changed video cards since the power outage, and the board was powering up before I pulled the HD since it couldn't have been trying to reboot without power. Does anyone have any thoughts or suggestions? I'd especially like to know if I can reset the red led. I switched the video card out to one that worked before, a Radeon 9000 Pro, and the red led was still lit. My next thought was to change the jumper setting on the mobo to the onboard video card to try to clear the red led, try to power up, then reset the jumper to AGP, and try again. Any help would be most appreciated.
My guess is that the power supply got wasted, and you're looking at a need to replace it. I'm not sure if the power supply took anything else with it, but you'll need to have another PSU in there to troubleshoot.
oooohhhh do I know how you :swear: feel!!! http://www.hardwareforums.com/showthread.php?t=5840 This is my post up there..... my generic PSU fried and took my mobo with it. Thankfully nothing else. Could be waht's wrong with your system. Good luck, I hope the PSU and mobo is all that was damaged. Keep it cool! The forum is behind you.....
Well, I bought a PSU tester. As soon as I disconnected all the plugs from the MOBO and plugged in the 20pin connector to the tester, the PSU fan turned on and the tester indicated it was ok. I reconnected to the MOBO, and the little red LED light up again indicating the wrong voltage video card was installed, even though before the power failure it worked fine. BTW, the PSU fan won't turn on when the littel red LED is on lit. My next thought is to reset the CMOS and try again. Any other thoughts before I do that?
All testers can be wrong at times. They sense for voltages, currrents, frequencies.etc.. under no load conditions and say it's ok. Best bet is to try using another known-good PSU. jUst my two-cents worth.
It could work, but I'm thinking that some components of the system got fried and probably it has gone a little hay-wire...
