Background information: System components only about 8 months old.
Motherboard: Aopen AK77 Pro
RAM: PC2100 Micron 128MB, and generic 256MB
HD: Maxtor 7200, 40GB
PS: 300 W
CDROM: Liteon 52X
CDRW: Acer (old one but works)
Video Card: ATI Radeon 8500 LE/128 MB DDR RAM
OS: Windows XP Pro
Now here's is the problem - System boots and POSTs just fine after system has been off for about two or three days. At the beginning it will POST everytime I restart or power down and reboot. After a day or so it will not POST anymore. In this not POSTing state I removed the video card, RAM, disconnected all the drives just to see if it would produce a error beep to no avail. I have run with either stick of RAM at different times but got same result. When I measured all the voltages at the end of the connector on the MB (when everything was running) all voltages measured properly. Could this be a PS or CPU problem? This is the thired MB with the exact same problems (doubtfull that 3 MB could be flakey in same manner). Any suggestions? Sorry about the long post but I figured it would be better lay out the whole picture at one time.
