new power supply - Drives won't power up

By oltclan4 ·
A friend of mine called me today to tell me her Win XP PC sudddenly stopped working. She had DLed a Windows update last night, restarted it, and it shut down after 10 min. It did this twice and broght her to the "do you want to start in safe mode" screen. she said no after the first time it shut down. The second time it shut down it would do nothing.
Initially, I thought it was the power supply, since none of the drive lights would light up, HD would not spin, CD drives would not open. I replaced the power supply, and the same thing happened. I took out one of the CD drives and connected it to her other pc (w/o IDE cables attached) and it operated fine (opened, light came on).
I reconnected it to the 1st PC, w/o the ide cables attached and it worked fine. Re-connected IDE cables - back to square one!! I reset memory, and all IDE cables to no avail.
She said she had not been experiencing any problems before this situation.

Any thoughts? Motherboard??

Thanks,
Paul

Connect the CD drives to the other pc, power and IDE cables, if it it works fine that eleminates the CD drive.
Take the known good cd drive from the second pc and connect it to the first PC that is having the problem.
Also try swapping IDE cables around.

I am guessing thhe issue is a controller(s) on the system board.

How does her machine respond without the CD attached? Nothing? Does it boot normally Can it go into Safe Mode?

I will try to go over there tomorrow, and try disconnecting and/or switching IDE cables for everything but the HD and see what happens. I hadn't tried starting it w/o CDs attached. I'll get back to you.

Thank you, answers 1 & 2, for your thoughts/suggestions.

Is it a generic PC or a brand-name?

Have you re-connected all of the power supply connectors to the motherboard? P4 power connector (if a P4 board)?

Video card and memory seated firmly?
Not kowing specifically what you're working with, it's just a guessing game.

It is a Systemax machine, P4 I believe. I reseated other items mentioned; I did not reseat the video card. I will try that as well, but would that affect the powering up of the IDE drives?

If it's a P4 computer you'll most likely need to Flash the BIOS to something newer than what is currently in it.

The older P4's didn't like some of the Windows Updates and the newer Dual Core ones don't get recognized properly on a M'Board without the latest BIOS installed.
