The Computers DEAD!!! sometimes

By sam3 ·
A friend bought a new "barebones system" with power supply,128 meg mem,500 mhz. chip, onboard modem and sound,agp video card,keyboard,mouse. No monitor,no harddrive.
I loaded(copied) all her data on to a larger harddrive,tested it for a few days and gave it to her.
First night online, Bam! it goes dead in the middle of sending email. I mean no power, dead, press the power button nothing happens.

When I come over the next day, remove all the cables, take out the cards, plug in the power, fires right up. But now the onboard modem won't work. replace with a isa modem ok.
Couple days later.... late at night sending email Bam dead again. reseat mem, reseat cards.... Ok it works.
Couple days later... dead as a doornail! ( when she goes touse it.
Call tech support. After a bit of back and forth, he says,"send it back, we'll check it here.) I send the box back.
He runs it straight for 10 days even downloading LARGE files (using HER AOL software, and id.)not a problem.
Back it comes, I bring over my surge protector (with tele connectors) connect everything (her old monitor, her old HP Deskjet printer)it runs fine till I leave, BUT you guessed it, DEAD that night in the middle of sending email. and wont go back on.
I tell her to remove all cables in the back (incl power,monitor printer) wait 1 min. and then plug inpower cord only. Its on. I tell her plug in ONLY monitor,keyboard,mouse,power. It goes dead!
Help!!!!!!!

The fact that this machine works everywhere else, points to incoming power from the wall circuit. Install a power conditioner/UPS your problems should go away.

The first place that I would check is the power circuit coming from the wall. Most computers upon running will in the area of 9 to 10 amps. This includes the monitor, everything plugged into the surge protector and the surge protector. If your firend is living in an older house, it may be wired with 14/2/g wire or maybe even aluminum wire. When the circuit heats up from use, the connection is lost. If you KNOW WHAT YOU ARE DOING, kill/tag the breaker to the outlet, remove the cover and outlet and inspect the outlet and incoming leads and make sure that the polarity is correct. If nothing appears to be wrong, plug in a lamp and energize the circuit. CAREFULLY, with rubbergloved hands, twist the outlet and see if the light flickers orgoes out. $10 to a donut, you will find either a broken lead, or the outlet itself is cracked.

If this computer ran for ten days without problems, it is doubtful that the power supply or the m/b is causing the problem.

It sounds like a power supply problem to me. I would try replacing the power supply with one that you know works good, or even buy another one, it would run you about 30 bucks. I assume it's still under warranty, in which case I'd give them a ring and ask for a new power supply. I take care of 250 computers, and I see this problem once in a while, along with computers that seem to have hardware die for no good reason. A power supply is the first thing I try, and 99% of the time it fixes it. Hope this helps.

I agree with the power problem, for under $10 you can get an outlet checker (looks like and oversized extension cord plug). This will give you a lighted indication of reversed power leads or bad grounding, what the lights mean are usually labled onthe side of this tester.
Or try another outlet, they can go bad or have a loose or bad wire connection.

check the motherboard installation if the spacer those 4 plastics or protruding nuts under your motherboard are in place. if they are absent then install them.if they are there then configure very well the jumpers of your mothbrd.particularly the disabled and enabled features of your built in modem and soundcard.

checked MB, all ok

It turns out:
Computechie, Big Ted, CertifiedAplus were on the right track.

How do I go back and give them credit?
