A lot of this post comes from another thread I mistakenly posted to after finding it on Google. It was suggested that I start a new thread describing my own problems. I was asked to specify more data.

PSU: RS-650-ACAA-A1 made by Cooler Master
Regular output is 650 watts but it can go up to 780

+12V Voltage - 12.03V
+5V - 4.73V
+3.3V - 3.28V

DDR2 Voltage - 1.92V
DDR2 Termination Voltage - 0.96V
CPU Core Voltage - 1.32V
CPU-NB HT Voltage - 1.36V

NB 2.5V Voltage - 2.57V
NB Core Voltage - 1.20V
SB Core Voltage - 1.58V
SB PLL Voltage - 1.56V
SiL3132 ESATA Voltage - 1.82V
Marvell LAN PHY Voltage - 1.74V

All these settings are the default set on an Asus Crosshair. Temperature with Windows XP loaded is usually around 40-42 degrees. I remember it being about 35 degrees earlier this week. After an entire night of being off, it was coming up at 30 degrees, but quickly rising to 35 degrees. I still have Arctic Silver on my X2. It is now at 42 degrees according to SpeedFan 4.32.

Here are parts of my post from the previous thread:
Asus Crosshair with 0802 BIOS Version.
AMD Athlon 64 X2 5000+ operating at 2.6 GHz.
2 GBs of Mushkin DIMMs in my system.
e-GeForce 7300 GT - 512MB

I originally did have other problems with this motherboard. After about six months of usage, the system does not boot. It will turn on, it just will not boot into an OS. I take it down to a computer store and it appears that I need to reapply the thermal paste. In the beginning, I had no thermal paste on there at all. I went with whatever AMD put on their CPU fan/heatsink combination by default. Read on the Internet, theories saying that it will be good forever. I got the impression it would be good for life. Well that life only lasts for about six months. I buy some Arctic Silver and the CPU and motherboard are working great together...until a new problem surfaces. If I command the CPU to do any task that is very CPU intensive, the system will immediately do a reboot. The monitor goes black and than different things have occurred on different forced reboots. On one occasion the PC speaker makes a long beep, followed by two quick beeps. I turn it off for about five minutes and when I turn on the power again, it boots just fine. The other occurrence is the system quickly booting back into Windows XP as if nothing was ever wrong.

I do not do any overclocking. I did use the NVIDIA GPU Ex but whether I enable it or disable it, my system still randomly reboots when the CPU workload becomes too intensive. I frequently have many auto-save features implementing its primary feature. That is the only software feature saving my work for those applications that support it.

Are there any suggestions for how I can personally find the defective hardware or what I should do to stop my system from randomly rebooting whenever CPU workload becomes too intensive? I have already tried resetting all BIOS functions to their defaults.
