2. Memory-could be faulty, could just be not making the full connection-take out the stick (s) and re-seat. If you have 2 or more and re-seating doesn't fix it, take them out and try then one at a time on their own. If one of them causes the problem, there is your answer.
3-PSU-Personally, I think this may well be 'it', but try the others first. Try and get your hands on a new (or at least different-known good) PSU (preferrably of a higher wattage than you currently have). Depending on what you've got in your PC, you could be running it close to it's limits and if you've installed something new-that could be the catalyst for sending your current psu over the edge, or it could have developed a non- fatal flaw .
4-CPU-It could be that your PSU has developed a fault-hard to really test. You aren't overclocking are you?If so, drop it back to it's correct level. If you are running an Athlon XP processor, try going into the BIOS and bring the frequency the cpu works on down (i.e. if it's supposed to run on 166Mhz, drop to 133) .
I've currently got an issue with my PC which does exactly what you are describing-I know the fault is in my psu, but 'underclocking' does the trick until I can land a good psu at the right money.
could be other things too-like some dry joint somewhere which isn't making the connection from cold, but once it's started and re-started a few times, it heats up and expands far enough to make contact to keep you running.
hope this helps
please let me know how you get on and i can help you further
