While running a couple of different apps today my computer (AMD Athlon 1.4ghz, Windows ME) locked up. I pushed the reset button and the comp turned off but wouldn't boot back up, when you turn it on the green light comes on and stays on and the red hard drive light comes on for about 3 seconds and you can hear the hard drive run for a second, both cd-roms flash their green lights while initially checking for cd's and then nothing, no more hard drive activity, no post, no display on the monitor at all.

Is my processor fried?, I tried removing my video card, unplugging the cdroms and floppy drive, reseating the ram and all connections and then restarting but still nothing.

What else can I do to try and diagnose the problem? Please give me some advise.

Thanks,

Chris

Fried?

Can you find another PowerSupply to hook up to the MOBO and drives? If nothing at all is showing up, that would be my guess.

If his PSU was dead, nothing would turn on at all, but as he explains his drives start up, everything powers on, but nothing happens, which is the exact same problem I'm having with my Abit TH7-RAID mobo.

is it that rough to hook up a PS?

Not all power supplys die hard. I have seen this before, and we all know this is a trouble shooting business. So, how tough is it to hook up a known good Ps and eliminate that?

if there is a possibility the power supply is bad, check the machine with a different power supply.

most problems with powering up are directly related to the power supply.

and it is true that not all power supply units die altogether, some can lose only a single branch.

I've also seen how some power supplies may appear fine upon DC analysis, but may have spawned an AC voltage that's fowling up the whole system. Check it with a voltmeter with the computer running. You should get no more than a tenth of a volt AC. One full volt AC or more will definately prevent a computer from working. If you find AC, just put in another ps.

Other possibilities:

Bad mobo (this dead, it will do what you're talking about. I changed a mobo out of an IBM that was doing the same thing a year ago.:D

Bad RAM (this dead, your PC won't have anywhere to put its scratch figuring, making it useless)

Bad processor (this gone, same as your brain made into tofu :dead: , fortunately fixing that isn't brain sergury.:tongue2: ).

The syntoms of all four problems are the same.

Many thanx to all, it was the power supply, just switched it today and the computer came to life, saves me from buying a cpu or motherboard and then finding out it was just the power supply.
