I recently purchased this pc, and for about a week it was running fine. Just yesterday, though, it began to randomly reboot. No error message or anything. One the of the fans audibly speeds up (I think the PSU fan, because I cracked it open and watched the CPU fan and it didn't seem to change speed. I could be mistaken though) then BAM... reboot. My temperature seems to be fine, I even downloaded a program to regulate the fan speed based on temp. I did a system restore, and uninstalled/rolled back a few new drivers. Nothing I've done has worked so far. I have a feeling its the PSU... either its not powerful enough to run the system or its faulty.

any ideas?

I would like you to download and install the program Speedfan. When you are done installing Speedfan open and look for 3 columns. One should have temperatures, the other should have voltages, and the last one should contain your fan speeds. When you have found this information please post to me in a column such as this: (Example)

Temperatures

Temp1: 30 C
Temp2: 60 C
HD0: 44 C

Voltages (only for desktops)

5V: 5
3.33V: 3.24

Fan Speeds

Speed1: 2480 RPM

(Remember this is just an example, please post your exact information)

If you are running on a Dell Laptop please follow these steps then post your temperatures, voltages, and fan speeds:

• Open Speedfan
• Click Configure on the Main Screen
• Go to the Options Tab
• Check the: "Enable DELL Support (use this function only on DELL notebooks)" check box
• Click Ok then Close Speedfan
• Start Speedfan once again

Then post your temperatures, voltages, and fan speeds.
