I recently was given a PC that I was going to turn into a storage and music server for me and my roommates. But when ever I turn it on the lights come on and after a few seconds it starts to sound an alarm, with a high than low beep over and over again but the screen never turns on. If I move the CMOS jumper from Normal to Reset and leave it there, the machine will turn on and the screen will come up saying:
Main Memory Clock is 100 MHz
CMOS check sum error - Defaults loaded
Warning! CPU has been changed
Please enter CPU speed in CMOS setup and save before exit!
The Main memory clock should be 133MHz but I guess it defaults to 100 when the CMOS is in reset mode. I enter the CMOS settings and put everything how it should be, save than exit. Then put the jumper back to normal and restart, but nothing happens. Some times I get the alarm error, sometimes it just sits there.
If I put the CMOS jumper in the reset position and tell it to continue after getting the checksum error it will boot all the way up and work. But only with the jumper in the Reset position.
Every so often the it will turn off and not come back on unless I plug in the power supply and wait until I hear something discharging than plug it back in and then it will turn on.
I think this problem either has to do with the RAM I have, or the mother board is bad. But I don't have another machine to test either of those with.
mobo: Epox EP-3SPA3L
processor: Pentium III 933/256/133
video card: In AGP slot, only markings say: Radeon RV100 SD32
I have 3 sticks of PC 133 RAM to try:
Kingston KCT-EN 133/256
Kingston KVR 133Q/256R SDRAM
Infineon 128 MB SYNC 133MHz SDRAM
I have tried all different combinations of RAM, but no consistency of if the machine will start, or do nothing.
Any one have any ideas or suggestions? Any help would be great.
