Computer Crashing

The PC is fixed. Turned out it was the mother board. Everything seems to be working OK at this stage.

Thanks to everyone who posted with advice and comments. Much appreciated.

Frankencomputer eh? Sounds interesting!!

P4 motherboard from across the road, P4 2.4 256mb ram and case with dead motherboard and power supply from other side of Leichhardt, power supply from a P4 1.5 from same street as P4 2.4. Good week for junk off the street.

The old P4 came with 512mb ram. Pity it was only 133.

This one is my bitsa. The good one is also dead. Medion computer about 2 years old with a suspected mother board. Won't power up and I have replaced the power supply.
The one I'm using is an AMD 750mhz
655 MB ram.
20gig Hdd
cd burner, CD rom
and it now has a working floppy.

Time to switch to Linux ---- we don't have any 'Blue Screens of Death' :) It's a Microsoft thingy:twisted:

Been having similar issues as you - computer will not run more than 20 minutes before crashing - cannot even do a backup bacause the system crashes before it is done.

What was wrong with the board - was a new one required?

Sounds like a heat problem to me. Are all of your fans working?

Try taking the side of the case off and stick a desk fan to blow into the case. Might just keep everything cool enough to back the data up.

HDD
Video card
Power supply
MB

Not in any order. Only way to find out - if it isn't fans - is to substitute parts with a working computer.

1) check none of the capacitors on the motherboard are domed. if they arent flat, you have problems.

2) check the heatsink on the cpu is not full of fluff and crap. clean with small paint brush and vacuum cleaner noozle held nearby to grab the fine dust.

3) check voltage at the molex plugs, anything under 12v or 5v is unacceptable, plenty of pinout charts on the net. low voltage causes heat.

4) if you have multiple case fans make sure they are pushing into the system so the air is being forced out thru the powersupply, can work wonders at times...

Thanks for the info - there is dust in the computer but not enough to cause an issue but cleaned anyway. CPU heatsink and fan clean and working, motherboard fan all OK, video car fan OK, have two sucker fans in the box all ok - they suck out over the CPU - just realised I didn't check the power supply fan - will do.

Mother board/CPU temps are within specs - under 50 even though it is hot weather.

Normal CPU usage (3 ghz twin pretend CPU) normally operates at under 10% usage but does spike up too 100% and the HDD does run more than is reasonable.

I suspect it is a windows stability thing or a RAM issue (dual channel 1 gb in 2 sticks). As most of the work I don't need that amount of ram I will take out a stick at a time and see what happens - other wise it might be off the the fixit man - but they know how to charge just as much as a landy stealer.
