Locked

Boot Problem

By mbpjc ·
I have a Compag computer with Win ME installed that will lock up after being on for a while. This is not caused by heat as the cpu is cool with a good fan. Also when trying to boot Especially after a freeze, the post won't do anything. The power comes on, fans start, HD spins then nothing. Monitor stays amber. After much plugging and re-plugging or after a long rest period (as in days), It reboots perfectly, but freezes again after a while. Any suggestions?

Check capacitors on motherboard for signs of bulging or leakage. Tops should be flat. First sign of impending cap failure is usually a slight bulging of the top.

If caps are going bad, mobo must be replaced.

Check the ram, if it is EDO may have one that goes out of tolerance from its mate after the PC warms up. This will cause strange intermittant problems/lockups.

SDRAM, If you have more than one stick in it try each individually if one works and the other does not you have found the bad one.

Won't post, so memory is not checked. I tried different memory and it did not work either.

Check the actual CPU and memory voltages. The BIOS will probably report these for you, or you can use one of many windows utils like Sandra.

It does sound like a power supply problem but is more likely to be PSU related than MB in my opinion.

Have you upgraded the processor or added drives? If yes I'd look long and hard at the PSU.

Just a FYI, don't be opening the PSU to check the capacitors in there unless you are a qualified electrical engineer.

A different power supply helped, but I replaced the motherboard anyway. Thanks for the response.
