PSU problem?

[Raz]

Hey

Just started having a new problem with my pc, even though nothings been changed with hardware or software - pc just goes into standby mode, with the monitor turning off. Happens when I usually run a program, even if it's boinc. Once or twice it's happened when I'm just browsing the net.

Any ideas? CPU temp shows 45+c, PSU is an enermax about 3 years old.

Thanks for any help
