PC Automatically Shuts Down, PS Fan continues to run.?

Check you Motherboard for distended capistors, the laymen translation, look at the barrel shaped things on the mother board, of the ends are buldgeing out or leaking out the top, you have a bad mobo.

Is it near a heating vent or something? The fan continues to run because something is too hot. If it's the cpu fan, it because the cpu is hot, it it's the case fans, it's because the over all temp of the chasis it too hot. Before buying another MB, I'd try running the PC without the side of the case on. You also may try cleaning the whole case, they can get cluttered with dust pretty quickly (especially if you have flat and not round cables) which can hamper air flow. I clean my case out once a month and I've never had temp problems. I did the same thing with my last computer (which still runs fine, give it to my sis with I built a new one) and I had it for five years. If over heating it the problem, then buy a new chasis, not MB.

As for the same model, good luch finding one if the computer is three years old. Furthermore, I think each MB has it's own serial number, so I don't think changing will work without reinstalling XP.

Hope this helps,

Here is a $10 solution. Replace the fan.

It is not doing the job of cooling properly. Probably you hear the fan noise to be louder than usual. The motor bearing has worn out. Also check for hair caught in the spindle. It has picked up the debris from the floor or the carpet and it has tangled in the motor. This is the cause. Replace that first and report back.

its possible ur comp overheats. this happened to my comp when the fan didnt fuunction. try running the comp with the cpu case removed so u can see if the fan is still turning. if not u hav to replace the fan. the comp shuts down or restarts cos the processor is overheating and to stop further damage. a comp doesnt shut down on its own for no reason, there is something seriously wrong. i think u shud just try once to see if fan is working and if it just shuts down again..dont switch it on again..go get it repaired.

also u can download some software on download.com to check ur hard-disk temperature. type hard disk temperature and search there..u will find a free software. if u get a blue screen of death u definitely shudnt switch ur comp on again.

replace the power supply
