new computer problems

i built a new computer and for some reason it will randomly lock up with the hdd led goes contantly red. then i reset it and it asks to select a boot device and will not find my hdd. if i unplug the p/s from the motherboard then plug it back it it will boot up fine. anyone have any idea what would cause this?

motherboard- biostar tf8200 am2
processor- amd phenom
ram- 4gb kingston hyper-x ddr2
hdd- 360gb seagate
500w cheap p/s

1995 Cobra

Hard lock ups can be thermal related. Check CPU cooling and HDD ventilation. Its also possible it could be the power supply dropping in efficiency to the point of causing odd problems. You might also try different combinations of RAM DIMMs (i.e. take out a couple until you can get it stable). If one is bad it could do some weird stuff to. Narrow the problem down by eliminating all of the possible causes.

well lcs display on the front of the computer says its 85F. witch is cool, the sensor is wedged in between the heat sink fins pretty close to the processor. i have all ready switched the ram around. this machine has vista64 home btw. i built one the exact same for my grandma and hers has 0 probs but she wont let me troubleshoot with hers.

Any info in event logs to help ascertain if it is an OS issue? Have you run memory tests? Maybe run a benchmark on your GPU and/or CPU to isolate the issue?

IMO, cheap PSUs is a good way to ask for trouble.
