Kingston DDR 400mhz pc3200 512mb
Maxtor 160GB IDE
350W Q-Tec Low noise PSU.
MSI K8T Neo2 Fire S939
When I used an ATI Radeon 9800SE with a ordinary 4-pin molex connector as the one used to supply power to a IDE hardrive I hade an uptime in about 15-20 minutes before the monitor status light starts blinking yellow and screen goes off. The computer is still running when this happends but screen goes off and I must unplug the power cord to the monitor and restart the computer. I have tried an TFT monitor without any result.
But when I changed to a ATI Radeon 9700 Pro which only uses a small type Molex connector, looks like the one used for power supplying floppy drives I got an significant increased uptime. The uptime increased to 1-3 hours.
May this be a problem of the PSU beeing to weak? Or may the AGP slot be broken on the motherboard?
Thanks in advance.
