I have an HP Brio PII 300mhz that is not booting up. When I press the power button, the computer makes a pulsing/clicking sound that continues until the power plug is actually pulled (cannot turn off with the switch). The power light, HDD light blink in sync with the pulsing. Even the fan for the MB "pulses" with each attempt to power up.
I have stripped it down and removed (one at a time and all) cards, drives and memory to try to isolate any devices that may be causing the issue. I have pulled the power supply and checked all connections from the power supply and power switch. Unforunately, despite having a multimeter, I am not terribly sure on how to use it to test the power supply on a PC.
The power supply is 145w. There are 2 HDD's, floppy, CD-ROM, internal winmodem, NIC and sound card in the PC.
Any suggestions for troubleshooting and isolating issue would be great, and if it does turn out to be the power supply like I believe, and reccomendations for where I can get another cheap would be great.
TIA
