I am having a problem where I start my computer it starts it goes to the windows xp loading screen then it restarts at the motherboard screen again. I know it isn't my ram, motherboard or processor because they are all new and it also did this with my last rig. It only gives me this problems on certain occasion. The only two things that it could be is my harddrive or my psu. The harddrive I brought about a year ago so I can't see that being the problem. The only thing it could be is my psu. The psu is a coolmax cx-550B it has two 12v rails 18 amps each 550watts. (I know not a good brand) I only am running one harddrive, one sata dvd burner and the rest of my specs are in my sig. I am just trying to narrow my problem down so tell me what you think is wrong.
EDIT: I went back to stock speeds and it is still giving me a problem.
