Hi all, well.... I had a few problems when putting my system together (thread here), but after replacing the cpu on Friday all was running well.
This afternoon, I was playing TOC Race Driver, when I went downstairs to make a cuppa. When I came back up, the PC had shut itself down. When I try to restart it, there is about 0.1 second of life, ie. for that fraction the system appears to be about to boot (the fan twitches slightly!) but nothing else. Nowt. Bugger all.
The PC has been running fine since I finished putting it together on Friday, and it had a good workout yesterday, during which the processor temperature never rose above 44.5C. I've tried removing the power cable and resetting the CMOS, with zero results. I've also tried removing the battery while removing the power cable while resetting the CMOS - still no luck. Also tried all this with the atx plug off the mobo.
I'm confused, because the system - like I say - has been fine, and had only been on for about an hour today. It's running with the sides off the case, and when I went downstairs all fans (cpu/northbridge/gfx card/case blower) were all working fine. All has been running stably until I went for my brew and came back to a blank screen. I've also just tried another PSU, and got the same result. :cry:


Anyone have any ideas what could have caused this? And, more importantly - any ideas how to fix it?

AthlonXP2400+ (with stock cooler rated to 3.2Ghz)
(using CoolerMaster Premium thermal compound)
Abit KD7A
256MB PC2700 Infineon DDR
40GB Seagate
40GB Maxtor
Relisys DVD Rom
Liteon 12101B CDRW
Inno3D Geforce3 ti200
350w Eagle PSU
MultiTech MT5600ZDXe 56k external modem (COM1)

did you have it on a surge protector? maybe there was a power surge and something shorted out.

[jayroller]

No, no surge protector . I'm guessing something is dead, but i'm not sure what. I'm wondering if the way there's momentary power to the board is an indicator of what has actually died..... looks like it's gonna be a long night.

EDIT - 19:05 21.12.03

Quick update - I took the mobo out of the case and tried firing it up on top of its box with nothing but the cpu/memory/cpu fan plugged in - still no dice. Changed the cpu for an older Athlon (known to be working) - still nothing. Luckily enough I have an asus mobo here as well, and that fires up from the psu with the athlonxp and memory in it. I'm gonna connect everything up and see what happens.
So, it looks like the motherboard has died - anyone tell me why that would happen? Or is it just one of those chance-in-a-million type things, and I've hit the jackpot?

I had the exact same problem before. Turned out to be the mainboard in the end
good luck.

Hi Jayroller,

I too had that problem one day. I was using my software just fine and the computer turned off. I tried everything to turn it back. All it would do is turn on for a second and then turn off. Almost like a "blip" of power but nothin.

So I changed out my Powersupply with my other computer and it brought it back to life.


Hope that helps

[I too dont like the sides, they get in the way. Maybe thats why my computer has so many problems though...]

A cigar for that man....
Took the mobo back to the supplier, put the replacement in, and we're back in business Ah, festive gaming is back on the menu - for a while I had the awful feeling I'd have to spend Christmas talking the family....
Thanks to all who responded - much appreciated, guys.
