PC Power Problem???
A friend has an old PC running 98SE. It will power up but after 1/2 an
hour to 1 hour it will die and not turn on. If you let it sit for another 1/2 hour it will power up and repeat the process. Power Supply or CPU/Motherboard? All fans are working and I have blown all the dust out of the tower. Thoughts? |

Assuming that you have access to some suitable hardware, I would try to
replace some hardware items one at a time. After trying each item put the original back and try the next in this order 1. Power supply (Most likely) you could also reduce the load on the PS by unplugging CD drives floppies etc just keep the bare essentials i.e Hdd and video 2. try a different Harddrive in the suspect machine. You could also try that Hdd in another machine but be aware if you go that way you my stuff up the installed drivers 3 disconnect one fan at a time and see if system goes down quicker, although if there is overheating you should get some warning beeps. Make sure you have a speaker plugged in to the motherboard most old towers/mbs had one good luck "Gre0145" wrote in message ... A friend has an old PC running 98SE.

If you post a bit more detail, like computer make and complete model number, that may make it easier for someone to make some suggestions. If the fans are working, and the CPU heatsink hasn't fallen off the motherboard, that makes the power supply a more likely culprit. Paul |
