HP a867c tower won't turn on

[ Edited ]

I had a power outtage in my place the other day and wasn't home to unplug my appliances.  I came back and tried to turn on my computer and it wouldn't start.  I noticed the green light in the back blinking and I could hear it ticking as well.  I unplugged the tower and let it sit for 30 minutes or so.  Still not working.  I opened the side panel and unplugged the ATX cable from the motherboard and waited for 3 minutes.  I plugged the power cord back in without reattaching the ATX cord.  The green light in the back stopped blinking and stayed solid.  None of the fans turned on, but I plugged the ATX cord back into the motherboard only to find that the solid green light was blinking and ticking once more.  I unplugged the ATX cord again and the light turned solid.  The tower still wouldn't turn on and none of the fans turned on.  I took a closer look at the components and found that I have two capacitors that are bulging slightly.  I am at a loss of what to do.  How will i know if there is something wrong with the motherboard or the power supply?  Will two bad capacitors effect the entire system like that?  I have important files on the tower and haven't gotten the chance to buy an external back up system and am currently low on funds.  Anyone know what I can do?

What model PC are you using?  Bulging capacitors are a bad sign. You probably will need a montherboard replacement. However, read over this article. Trouble Shooting Power Supply Issues. Your PC is probably over 5 years old si it might not make sense to have the PC repaired but your local PC repair shop can give you a quote.


You might want to contact HP support. HP's support number is 800-474-6836 or 800-HPINVENT


Your files can always be extracted from the hard drive if the hard drive is not defective.

Re: HP a867c tower won't turn on

the blinking green LED on the power supply can sometimes indicate  that the power supply and the motherboard have both failed.  For what it would cost to replace both of those components you could almost purchase a new system.
