Default pc randomly restarts

hi, i have a pc and when i first start it up my pc will start, shutdown, start, shutdown, rinse, repeat. It will do this until it finally stays on, and half the time it stays on the screen wont even get any input and will go to hibernate mode. it also will randomly shut down and restart. i need to have this fixed, but computer techs are worse then mechanics when it comes to screwing the unknowing customer, and i built this one on my own so i feel confident that i can repair it. as of now my senses tell me it is the power supply, but i can not be certain. any ideas?

amd athlon 64 3200+
nvidia geforce 6600
1gb kingswton memory
128 hard drive (cant remember brand, ill tear find out if its needed)
dvd-rom dx-dvdr 100 (thats what device manager lists my drive as)
allied atx-500 power supply (the suspect)
lmk if u guyes need anything else... i need to get this finished so i can not worry about it for my online college class over the summer... plus WoW is suffering too

Can you boot to safe mode with no problems?
Change the world. Of one person. Today.

If your equation requires either a complex combination of variables to get the desired result OR you can't seem to get the result regardless of the variables....it ain't your variables, it's your constant.

no, when its going through its little "seizure cycle" it wont even boot to anything, the monitor wont even get a chance to get turned on or have a signel sent to it or w/e it is.

I guarantee it's your power supply.

EDIT: On that notion, check your voltages with this guide if you can. Post back with the results.

Intel Q9400 | Gigabyte EP45-UD3P | G.Skill 2x2GB DDR2 1000 | XFX HD5870
