Random restarts

[point4life]

Since I've added my Hitachi HD (see below), I've been getting random restarts while the computer is idle in Windows. I suspect the power supply, but the voltage readings from Asus Probe seem fine (+12V@12.403; +5V@5.107; +3.3V@3.36; 1.616 Vcore). The temps are fine too (34C CPU, 34C System), and I'm running the latest mobo BIOS. Any ideas?

Well, if it's the power supply, the voltages wouldn't necessarily drop. When a PSU causes a PC to reboot it's because it has been overloaded. Try running prime95 and accessing hard drives at the same time, or running 3DMark. The idea is to use as much power as possible at once. If it restarts, you probably need a better PSU. Now, if it's really "random" as you say, then it could be something else, but I have a feeling it's when you're using up more power than idle.
