I was on my the computer a minute ago and then suddenly the win98 shutdown screen came on and the computer turned off. I was in middle of ripping an audio cd and browsing CAA.
The problem is, the damn computer won't power up now anymore. No response, nothing, with the power button is pressed.
I'm absolutely bewildered, because I can't imagine what went wrong. I wasn't doing anything different. The computer is an AMD XP2400 with MSI KT2 Combo motherboard, Xsonic power supply, all other components pretty ordinary. I put this computer together myself, but all has been working well for the last 3 weeks, until now it decided to turn itself off.
Since there's no response to the 'on' button, it could be a power supply problem. But then, why did the win98 shutdown screen come on? Or perhaps a motherboard issue? Thermal shutdown?
I really need to get this computer up and running again, I'm on a spare computer that doesn't have anything loaded on it. Any ideas anyone?

Have you unplugged the power from the power supply and then plugged it back in? Sometimes this resets freaked out power supplys... otherwise looks like the poewr supply has let go...

Thanks for the quick reply. Yeah, unplugged and replugged. Even swapped the lead. But if the power supply gave up the ghost, why would the win98 shutdown screen come on?

Did your CPU fan stop working? Some motherboards have a high temp shut down to try and save your CPU. When this happens, it shuts down windows instead of just switching off. But this probably wont tell us why it doesn't turn on again. Have a look at the CPU to see if it is burnt/melted/smells. Since the 2400+ is one of the hottest CPU around, and because it is summer, it is easy to overheat your CPU.
Hope this helps

OK rip off the ATX cable (from the mb)... locate the green wire in the loom and short this out to any black wire in the loom (use a paper clip or something) if the power supply fan doesn't start spinning the power supply is shagged

Bugger me, the fan does start spinning. Motherboard problem then?

Yeah it looks that way hey - try clearing the CMOS on it and trying again.... not looking good though...

How do I clear the CMOS, especially since the computer won't even switch on?

There's a jumper on the board (somewhere LOL) or jemmy out the watch battery looking device for a few minutes and then put it back in.

Try taking the CPU out of the socket, waiting 5 minutes and re-seating it. AMD's can be a bit queer and need that from time to time.

Ok, I read the manual and used the jumper to clear the CMOS. The computer actually started to power up, but because I only had the power cable plugged in, I turned it off again and then started plugging in the monitor etc.
While doing this the computer powered up (by itself) then powered down. Now it won't respond to the power button anymore . I tried clearing the CMOS again but it doesn't work anymore. No response, nothing.

If I did that would I need to replace/get a new thermal pad for the heatsink?

This may suggest something is tripping out your supply - try unplugging everything (disk drive wise etc) and plug things back in one at a time till it refuses to start again...

You should use thermal interface paste. Thermal mats arent very efficient.
But yes you will.

I am bewildered now... Tried the computer later tonight, and it just booted up, all working fine. I don't understand at all, I didn't change anything
Overheating problem perhaps? But then I did try it later when it was cool, and it didn't work.
Lucky I didn't rush out to the shop for a warranty claim, they charge $25 to test if it turns out the component was fine. I'd hate if this is an intermittent motherboard problem...
