Fixing Hard Drive Issue for P4, RAM, Mobo & Power Supply

[PremO]

Ok here's the deal:

I received a p4 3.0 gig, 1 gig corsair ram, a new mobo, and a new power supply. I took my video card out of my old comp, along with my cd-drive and harddrive. I plugged everything in correctly, but, once my computer boots from the harddrive, a black screen comes up, then a few seconds later, a blue error screen flashes for a split second, then the computer restarts. I personally think that it is too much new hardware to use the same harddrive, without reformating it.

If anyone knows why this is happening, or if I indeed do need to reformat before i can use the harddrive, please let me know. Thanks :)

You don't have to reformat your hard drive, but you do need to reinstall windows. Whenever I reinstall an OS, I always format, but that is up to you.
