crazy blinking lights!

[thegibb20]

I'm working on my neighbor's old HP, and it's acting really weird. When i try to start it up, the floppy, HDD, and power lights blink rapidly at the same time, and the comp. won't start up. No fans or anything. Any thoughts? My guess is a busted power supply, but it could be the mobo...your help would be appreciated 🙂

Comp is an HP from '98, 333MHz with a little 200W power supply.

power supply most likely but thats an old board too.

The easiest way to check it would be use a different psu with the board in question and to also try the psu in question with another motherboard.

I have a Compaq PSU from a Presario K6-2 350 system you can have for the price of actual shipping $5-8$ if it comes to that 🙂 I would reseat everything, check all connections, and pop the battery and replace it before doing anything else though.

Probably not a power supply, but it is some defective unit... memory module, something in a pci slot, defective USR winmodems will cause this, bad cpu's, bath motherboard, defective cable... defective CPU fan, defective IDE cable... Lots of dumb hardware issues will affect old HP's even Office 97 Professional will cause it. HP Power supplies are so fragile they just blow, rather than causing problems. First thing I would do is change out all the memory modules and start with a 32 MB PC100 or if old enough, a PC-66. PC-66 memory did this kind of crazy ruination all the time not too many years ago.

What is the HP name of the Motherboard? Look for names like Cognac, etc, around the edge of the board. Give us the BOM and SWOM, ID, etc off the back of the computer to I can look it up in the shop manual for troubleshooting HP's.
