Dear Listers,

I have built myself a computer with forllowing specs:
- ASROCK i845GL mainboard (C-Media sound, Intel Extrem Graphics and Realtek
NIC on board)
- 2x128MB DDRAM sticks
- Intel Celeron 2GHz (socket 478)
- 300W power supply
- 1 40GB WD ATA-100 HDD
- 1 SONY CRX-140 CD-writer (4x8x32 speed)
- 1 AVer TV Go TV-card
Quite a basic system for the least money.  This syetm is protected by a UPS.

I have thsi system up and running for about 2 months.  But in the last 2
weeks it started to reboot itself irregularly, ie. after 1 hour, 2 hour or
10 minutes etc.  Sometime it stayed up to 10 hours continuously.  No
indication on when it restart.

It restart under W2K, WinXP, WinXP SP1, what ever I tried on it.  Having all
sort of security like F-Prot Antivirus, ZoneAlarm, all updated.
The only thing I could suspect was the voltage as provided in the following
report, which show the -5V and -12V a little bit too low for the standards.
My question is that what causes this low voltages?  Is that a problem of the
on-board voltage stabilizers or the power supply unit ( which I just
replaced by a new one 3 day before).  I really need to find out what is
faulty so that I could get it replaced under warranty.


Thanks a lot.
Phuong
