Computer Shutting Down

My computer is just shutting down whenever the room temperature goes up at all. The hope was that installing a copper heatsink / fan to replace the stock AMD one, and a pair of case fans, bringing them to 3, would help the problem. However, motherboard monitor is showing cup temperatures of 168 egrees F.

The strange thing is that I went back and reinstalled the fan thinking I had screwed it up some how the CPU was cool to the touch. I am using a thermal paste and a huge heatsink/fan. So I have no clue what to do next.

My setup:
Asus NForce2 Deluxe A78NX
Crucial 1G memory (2x512)
AMD Athlon 2.1+

All the setting are stock, no overclocking. I have the loaded the latest Asus bios for my MB. The system ran fine for almost 2 years now it does not want to say on at all. When turned on for the day it will run for 1/2 hour or less then shutoff then it will not even make it through the loading of XP.

Please Help 🙂

Thanks

Based on the article and the instructions for the heatsink I got it should be on fine. In addition, the stock heat sink/fan combo was on the chip for 2 years before this problem developed. Had though maybe the fan was going on it so replaced it with a copper one with a much larger fan. Installed it per directions, didnt work so tried it again 🙂

Still dazed and confused 🙁

If your getting 75 C + temps I doubt the heatsink is on right. 168 degrees F=75.6 degrees C. It should be more like 40C-45C at boot up.
 
1. Did you use a thin coating of thermal compound (Arctic Silver, etc.)?

2. Can you get into the CMOS and stay on? If so, does it show current temps under "Health?"

3. Does your CMOS have temp limit settings? If so, have they changed, or is the temp near the set limit?

If the temp limit is set too low (based on the correct values for your chip), set the limit higher.

If the temp is high, suspect your heatsink is not properly installed.

If the temp is within normal limits, your power supply may be overheating. You can try opening it up and cleaning the fan and heatsink's inside. If that doesn't help, you may need a new power supply.

Hope that helps. Good luck. 🙂
 
Mea Culpa

It was number 1, the guy at the store were I bought the thermal paste/fan said to use it liberally. Thin coat did the trick down to 28deg C 🙂

Thanks All
