Well for the past few weeks (probably 3-4) I've been using my new computer every day. Last night I was on for about 1 1/2 hours then I shut it down and went to bed. Today, after returning home from school, I go to start my computer and then I fetch myself a drink. I watched a little news, return and my monitor is "idle." (Orange light, not green) I smack around the mouse a bit. No response. I poke some keyboard buttons. Nothing. I notice the keyboard lights aren't on, and pushing Numlock does nothing. The optical mouse is lit, and moving it around causes the mouse to turn bright red as in normal operating conditions.

I tried rebooting, it reboots, but no response from my keyboard/monitor. I then cut off the power supply and the monitor. I unplug the monitor from the computer, and replug it in very securely. I then turned the surge protector off/then back on. Then I turned my monitor on, the power supply back on, and turned the computer on. Keyboard lights blink, but now I have no monitor, no keyboard response (numlock/capslock/scrollock won't come on), and no mouse (the mouse won't light up). The network switch has my computer's lights shown as on, so the network card is working, and I opened the computer up and put a different monitor on it (only thing connected). All the fans (video card/CPU/northbridge/case) all come on, the motherboard light comes on, the power light on the case comes on, and the HDD light comes on at first. CD-Rom's both spin when the computer is started. I'm very stumped and disapointed.

The CPU is a AMD XP 1900+. The video card is a GeForce3 Ti-200, and the motherboard is an AK31A Revision 3 Shuttle motherboard with VIA chipset. Please somebody help.

Is my motherboard fried? What should I do?

Hello BrokenAthlonXP, not another one! At this point I would say if a clear CMOS doesn't fix it, it's time to replace the CPU/Motherboard. Still under warranty?

Thanks E.S. I guess the clear CMOS wouldn't hurt anybody at the point. It's already beyond help it seems. And I'm the same BrokenAthlonXP as before. :-) The CPU's dandy I think. I got the old one RMAed. Oh what a lovely process that is, I might have to RMA this motherboard too. I have a feeling that previous CPU problem may be the cause of this. Oh well, thanks for the suggestion, and it couldn't hurt, so I'll try.

Silly post preview kept me from posting, so now I don't have to double post. I cleared the CMOS like the mobo manual described. No luck. Your probably lucky though E.S. Because had that worked, I would've had to marry you. A BIOS reflash disc is another option, unless there's no sense in that. I dunno, it's just being gay.

Well, If the Bios boot block is still functional, a bios flash wouldn't hurt a dead board as it stands. My wife probably wouldn't condone me getting married to someone else anyway! LOL.

Well unfortnuately a friend suggested that my CPU could be to blame. He hinted that I check the heatsink, which is installed very snuggly. I doubt that's my problem. Well, I HOPE that's not my problem. A 78 dollar motherboard is one thing, a 260 dollar CPU is quite another matter.

I wanted to truely narrow my problem down, so I removed everything. And I mean everything, all that was left was my motherboard/CPU. I plugged in my optical mouse to see if it would light up on bootup. Nothing. Fans spun like they should, the motherboard light lit up, but the mouse remained dead.

That eliminates the possibility of a fried video card/add-on card/drive. But that still leaves the CPU as a possibility. :-\ And I don't have a known good processor to throw in there to test if my board is bad either. Joy joy. I tried a boot disk, and nothing again. I'm at a dead-end. I was just gunna buy a new board, but with the possibility of a dead processor, I don't know what to do.

Thanks for your help E.S. I'll let you know what-ever becomes of this BrokenAthlonXP

Another broken Athlon is a possibility but unlikely as I think the CPU would give the no fan spin on power up as last time the CPU was bad. Sounds more like a Voltage regulator on the board has gone kaput as there is no indication of I/O with the keyboard or Optical mouse lighting up.
