Power Problems

Post by mharrris » Fri Aug 01, 2003 2:18 am

My PC will not power up after it has been shut using the OS (Win98se) or with the power button. If I just do a restart, no problem. It will only power up the hard drive and CD-ROM drive and I never get any video. I have to remove the CMOS battery for about 5 minutes before it will repsond to the power buton again and boot up with a video screen, so I have to stop it and reset all the bios settings, it reboots and all is well until I shut it down. What could be the problem?
:cry:

8O I replaced the CMOS battery, but there was no change in the problem. It still will not completely bootup after being shut down. Are you talking about the capacitors on the motherboard?

In most cases the leaking capacitors can be identified simply by looking at them (lots of photos can be found here.)

Hi there, I found a good article on how to Replace the blown capacitors on your motherboard yourself looks pretty easy if you have some replacement caps.
