System restart without error

[Guest]

Hi all,

I am bit worried about a problem I have encountered lately with my PC. All
of a sudden the system restarts with no reason. I know that this is not a
windows software error because I have disabled the "automatic restart in case
of an error" option. So I assume this is a hardware problem/conflict. Also I
know for sure that it is not temperature related problem either, since
whenever a restart occured my PC was in idle state, and anyway it have not so
far experienced a restart while I am playing games where the temperature
increases significantly then. Could it be a PSU problem? (I have a CHIEFTECH
350WATT PSU installed 5 months old). Maybe a motherboard problem? (The
mometherboard is an ASUS P5GD2 DELUXE bought brand new two months ago -
However all the mobo voltages (12,5,3,Vcore) values seem correct to me).
Please also note that my system restart is somehow rare (occurs once every
3-4 weeks). I have also tested the memory (using memtest86), as also the two
HD Drives and found no problems. My machine has the following specs:

INTEL P4 3.4GHz L2 CACHE 2MB
TRANSCEND 512MB DDR2
MSI NVIDIA 6600GT 128MB
LG internal DVD ROM
Plextor internal SCSI CD ROM
Adaptec SCSI PCI adapter
Two Western Digital HD Drives (one IDE, the other SATA)
External USB maxtor HD
External ZOOM USB modem

Many thanks for your help.

Have you checked your Event Viewer for any error messages? How's about any
of the myriad log files that Windows creates - just search for anything
created around the time of the restart.

350 watts is awfully little to power your system, I'd say that you need at
least 450 to 500 watts for what you've got. Here's a link to a power supply
calculator that may help you estimate your needs:

First of all let me thank you for your time to reply. Now...

There is nothing created on the event viewer (I forgot to mention that).
Since the problem must be hardware (there is no BSOD) I don't think windows
would register this problem in the event viewer. It is difficult to check for
log files since I cannot really recal the time of the reboot accurately.

Don't you think 450WATT PSU might be a little bit of an overkill for my
case? I don't think that I have such an overloaded with devices PC that I
would possibly need more than 350WATT. Again I might be wrong. The system
restart that happens on my machine is simillar in response to pressing the
reset button located on the ATX chasis. What I mean is that my PC does not
shutdown completely and suddendly boots up again. The reset is instant. Is
that the PSU you think?

Thanks once more.

You appear to have a handle on checking the obvious culprits for this type
of behavior. It is possible, since the problem is so periodic and random,
that it's a problem with the power going to your computer. You might want
to get that checked out.

Thanks for the reply. I am thinking of buying a UPS and see if the problem
happens then. Two more things that I would like to ask you.

1) Do you know any good application for testing the motherboard?
2) When windows xp shuts down abnormally shouldn't windows check the HD
drives for any errors on restart? This doesn't happen in my case. I can
recall such an action being taken by windows in the past.

Thank you in advance.
