Start Up - Booting problems

If replacing power supply doesn't work or if you want to test for culprit:

Disconnect power leads from all drives (HDD, FDD, and Optical drives).

Remove any cards not needed for basic boot. Essentially everything but video card.

Try to boot up with minimal configuration. If successful, sequence components back starting with HDD, then Optical, then FDD, and finally add in cards.

You quite possibly have an intermittent short or ground caused by power connectors, bad drive, or faulty card (most likely modem).

Loads of luck.

You may have a bad expansion card, typically a defective modem, or other card. Pull each card out one at a time, then re-power up.

I have seen this alot when internal modems are hit by an electrical storm. Normally, removing the defective modem, the machine will boot up normally. If this is the culprit, you can pick up a replacment modem really cheap!

Good luck!

Hi,

Also check your mobo for dead electrolytic capacitors. These are little cans sitting up on the board, usually near the CPU. If any show signs of bulging, on top or the sides, they are shot.
Unfortunately they are very difficult to replace, requiring sophisticated unsoldering equipment. Normal equipment usually results in damage to the mobo. As a last ditch effort you can try to physically chop them away until just the leads stick out of the board and solder new ones to these leads.

Good luck.
