I have a p4-1.7ghz on an Intel D850MV mobo. Ever since i got this PC, I have never been able to run this on a UPS (uninterrupted power supply). This is the strangest thing I have ever encountered with a PC in all my life. My UPS is a 500va system and worked absolutely fine with my older p3. But this thing doesnt work at all with the new p4. I thought that the P4 may need a larger UPS with higher battery capacity so I have tested this with a larger UPS with capacities of 1kva and 1.5kva. But this thing jsut doesnt work.
On power failure this PC reboots...where as if I connect another PC to the same UPS and simulate a power failure they dont reboot. This situation is so bad, that even in case of a power fluctatuation, my UPS boots only THIS PARTICULAR PC...the others keep running the way they are supposed to...I am wondering where I should start looking for problem in this PC? I have 2 baracuda 40gb drives in this system and I tried to use UPS with one REMOVED/disabled...to chk if it works with the UPS...no luck.. I have tried everything I can think of short of re-installing the OS...which is WInXP professional.
The PSU on my cabinet is a standard one that comes with a p4 setup.
Any advice would be highly appreciated.
