I am going to stop trolling for a few minutes. This only happens like once a week so listen up
You can really have some good times with your computer. You seriously should learn to fix it yourself. Nobody cares about how it runs but you. If you take it to some jackhole and tell him to fix it, it's not going to get done right. Even if you have a father/brother/boyfriend/whatever that you LIVE with who is a Lunix tard and fixes computers for a living, he can't fix it like you can. Even if you're mediocre at best dealing with hardware. Only you use it enough to make a true diagnosis of your computer's health.
Start troubleshooting. Rule everything you can out, then make an educated guess about the source. You know where all the components came from (or have at least a good guess). You know that hard disk failure is probably not the culprit because it's new. Did you install Windows from scratch on it, or did you use some utility to move it from your old disk (like MaxBlast/dd/etc.)? Can you consistantly get your disk to register in the BIOS? Can you make it consistantly fail? If either is true, you found the cause. Try replacing the IDE cable. If that fixes it, you found the cause. Try removing one stick of RAM and see if the problem happens still. If so, take it out and try the other. If still, try one stick in the other DDR channel or another slot. If that still doesn't fix it, you ruled out a RAM error too. Remove all PCI cards but the graphics. Remove all other disk drives. If this doesn't fix it, you've ruled out the possibility of a power drought (not enough power from the power supply causes brownouts that show this kind of behaviour).
Try anything else reasonable you can think of. If all else fails, you have a bad IDE channel on the motherboard. In that case, you need a new motherboard.
