PC just loses power

  carmichy 16:20 16 Jul 2008

I now live in the Philippines and have just came across an unusual situation with this particular PC. It loses power, switches off for no obvious reason. My other PC's will keep running but this one just closes down for no reason at all that I can see.

When it boots up is goes through the diagnostic checks and it says there is no channel 0 IDE 80 cable connected but it will still but up and run for a time and then power down. Windows XP Professional.

When it comes to Computers the Philippines is not so backward. I just need pointed in the right direction

the cpu might be getting too hot and the auto safety on the chip is cutting it off. see if the fan is clogged with dust stopping it working properly. only other thing I can think of is a faulty psu, this can cause all sorts of problems.

That looks like the answer I have not thought of yet. My repair shop is next door to a Construction Supply Company and the dust from there would cause that. The fact that it only happened with one PC confused me.

It is now bedtime here so I will try at your 02:00
and update you on the the answer for your interest. Salamat Citadel

If you can't fix the problem you should have a look at UPS's.

Certainly sounds like a overheat or dying PSU problem.

I have blown all the dust from that PC but have not had the time to let it run for any length of time to see if solved the problem.


We have to use UPS's here as a must. Brownouts happen here quite frequently. Also all PC's are connected through AVR's

80 wire cable is for the Hard Drive a Flat Ribbon cable, looks like its connected with only a 40 wire. Get a new 80 wire one and try it. and as above check the cpu heatsink is clear of muck

Thank you for all the replies to my problem. I followed Citadels advice and used a blow gun on the aforementioned PC. This also related to the advice discussed in your links Fruit Bat/\0/\. I also bought a new 80 wire IDE ribbon following your advice woodchip and the problem no longer exists.

All the PC's I build here are from parts bought individually and as those of you who build their own PC's will know if you create them then they become part of your family and like members of a family they only come back to you when they have problems.

Your advice is well appreciated and I hope I do not need to avail of that advice too often but it is good to know that it is there when needed.
