A good 130W PSU is worth much more than the cheapo 350W PSUs found in a typical budget PC (eg the type where the case with PSU cost less than £10). So 130W is probably OK if everything has been properly calculated. But it's one of the first (and easiest) things to rule out when problems occur. I've seen functional but unreliable PCs become rock-solid when replacing a cheap 500W PSU with a good 350W model. (Much the same effect you get when replacing an expensive proprietary OS with a free OSS alternative, come to think of it).
The use of memtest86 (as suggested elsewhere) coupled with testing with a decent replacement PSU narrows down a surprising number of faults. In fact, faults which don't show themselves from one of these two, and persist past an OS reinstall, are often more trouble to fix than they're worth. IME anyway.
