No more boot...

[phil1415624]

Hi everyone, I'd need serious help. I just turned my other PC on
(PII 360 MHz) and it was loading normally. I just left for maybe five minutes to play a little guitar then when I came back, the screen had a scrolling white bar... I tried to move the mouse but nothing changed so I pushed the reset button but it stopped loading before the single beep... I get CD drive activity and the fan is working, but nothing else works... Could someone help? http://www.PCGuide.com/ubb/frown.gif

Make sure the memory and video card are both securely inserted, and all connections are secure.
If they're ok, then it's either a bad motherboard, CPU, memory, or video card.
Either swap them out or have them tested to find the culprit.

Hello phil

I'm using diagnostic flow charts.

1. The PC is not dead because you have lights, fan etc.
2. POST did not run and that there were no audible beeps. This is, therefore, a POST problem.
3. I will assume that the power supply voltages are correct.[test if possible]
4. Disconnect all peripherals and system adapter cards except the keyboard and monitor.[After switching off and disconnecting from the power source naturally]
5. Boot the PC and if POST still does not run you have a faulty system board [This is only if your power supply is good](So says the chart but I wonder about the video card).
6. If it does run; re-connect the floppy and run advanced diagnostics if you can and test the system board. If the system board fails the tests then it is faulty. If it passes the tests then:
7. Switch off, re-connect one peripheral or adapter card and reboot. If post does not run then this last item is faulty. If it does boot, test this last item with the diagnostics software. If it fails the test it is faulty.
8. Repeat step 7 until all items are reconnected and tested then re-test the whole system.
If it still does not function send me an Email.

If you can't use diagnostic software you'll have to do without and see if there are signs of problems or things appear to work.

Most modern computers have a wire that runs from the on/off switch to the motherboard, make sure that this wire is still connected to the MB.

Probably you've already done this though.

If you've disconnected everything, HD's, floppy, video and sound cards, and still no lights or fans will come on, then it's your MB - sorry.

Sorry, my post above was meant for another thread. Don't know how it got here.
