Computer Shuts Down Randomly

The last few days my computer has been shutting down randomly, sometimes within a few minutes of turning it on, sometimes after several hours of use.  My computer is only about a month old, the system is as follows:

DualCore AMD Athlon 64 X2 3800+
Asus A8N32-SLI Deluxe Motherboard
OCZ 1GB PC3200 Gold Edition 2-2-2-5 Dual Channel DDR
OCZ 520W PowerStream SLI Ready Power Supply
Seagate 160MB Barracude 7200.8 Serial ATA Hard Drive
nVidia GeFroce 7800 GT (x1)
Windows XP Home Edition

I have performed scans with Windows Defender, Spybot, Adaware, www.spywareguide.com, housecall.trendmicro.com and www.bitdefender.com.  No viruses and no spyware can be found.

I checked my BIOS, my CPU is running at a temperature of 48 degrees C (118 degrees F) and my MB is running at a temperature of 36 degrees C (96.5 degrees F) so I am pretty sure this isn't a temperature problem.

I just got Everest Home Edition and ran a Report and everything looks good, you can check the report at:

I cleared my Event Viewer.  Since I have had three shut downs and the Event View shows nothing under Applications or System.

Windows XP management is set to only turn off the monitor after 5 hours.

I have removed the option to automatically restart in Startup and Recovery but the problem is still happening and I still get no error messages.

Any suggestions?

Thanks.

Boot it up with a Knoppix CD http://www.knoppix.org/, this will let you know if it is a driver issue or a hardware issue.

You may also want to check your hard driver connectors and your power on switch.

Hey brother, Callandor is right, check the power supply connectors.

Generally computer shuts randomly due to overheat and so it goes off just to protect your CPU and the other is the lack of power suplly, there might be a corrupted cable that is not transmitin propery the power it needs. It's just a system problem.

you can also diagnose it by starting with the minimum connected :
mobo, cpu,+1 ram stick, video card 1 harddisk, keyb and mouse.
if still reboots, it is one of the above, if not, add hardware  and test.
BTW - did you test with another power supply? they can cause it too.

...and did you run a disk scan for errors yet ? that may give some info too.

The computer started shutting down so frequently I couldn't get back on to check for postings.  I knew it had to be a hardware issue.  When checking inside the computer I noticed that the hard drive was pushing the power connector on the motherboard and that a small touch would cause me to lose power to the motherboard.  I have moved the hard drive to a different location and haven't had problems since.  Thanks.
