PC Will not Power Up

[crmayer]

I have been reading some other threads here and have some similar problems, but it seems that all have just built, or upgraded, or changed some PC setting. I have a pc here at work that when the user hits the power button in the morning, the pc's fan and drives start doing their thing for about 4-5 seconds and then it stops, nothing on the screen or no noise. After a breif pause, if you hit the power button nothing happens, you have to hold it in for 5 seconds, which tells me that the pc is on, but hung somewhere. If the user attempts to do this, the computer will eventually start and runs fine all day. Yesterday I had the user pull all power from the pc, wait, re-attach all power and then start it and it started, today she had to go through the start/stop process 3 times before it started. I have read alot of threads that point to mobo, cable connections, power supply, POST, bios, etc... The thing here is that nothing has changed, so I am leaning towards a hardware failure, but not sure what hardware and/or how to test it to see what is causing it.
Any help would be very usefull. Thanks

Suspect the power supply is getting cranky in its old age. Generally it is a sign of a crowbar shutdown because the P/S thinks it is having to supply excess current.

But this symptom could also be of a wakeup switch that is shorting, or not opening as it should when released. (ATX isn't it?)

Any advice I give is my best judgement based on my interpretation of the facts you supply. Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

To be 100% honest with you, I am not sure. The computer is at a remote location and I was looking for possible solutions before I go there to fix it. I found a thread very similar to this and it seems everybody says to start with the power supply. The computer was purchased from a local office supply store. I believe it is a corsair box, if that tells you anything about what is in it.

SoOunds like the power supply is dying a slow death. Replace it.
