I suspect this may be a power supply unit problem, but I doubt very much that it relates to wattage. 350W should be fine unless there are heaps of drives and other components installed.
The problem will most likely be that it's a cheap, generic power unit, which doesn't provide reliable and stable voltage and wattage levels.
More expensive power supply units from reputable manufacturers such as Antec, Thermaltake, OCZ, Zalman and the like are far, far better to use, and a worthwhile investment. Remember, if a 'cheap' power unit blows, it can take thinks like motherboard, processor, video card and others down along with it!
This could also be a RAM problem. With 1536Mb of RAM installed, there's obviously 2 or more modules installed. If they are different brands and mosels, there could be a conflict between them, especially if any of it is again 'cheap, generic' stuff. Try different RAM configurations:
If you have 3x512Mb, and two of them are identical, try using only those two.
If all are different, try using only one at a time.
etc..
Isolate the problem if it exists. You do not NEED that much RAM for games!
It could also be a software problem. The only real way to establish that the problem exists in hardware is to format, reinstall using the latest device drivers, and load the games again. Give them a good workout on a clean and fresh system. If the problem persists it is definitely a hardware matter.
