Hi, i'm trying to help my friend put a computer together. i got all of the parts (except HD) from my brother, so thats an Antec case with a P4 2.4 ghz, 1.5gb RAM, antec 430w PSU, an ASUS vid card, sound card, i think a sony dvd-rw, all on an ASUS P4S8X-X mobo, and then she bought a 160gb Maxtor Basics ATA/100 HD. i tried putting it in and booting up, and installing windows. windows runs fine thru installation until it's finished copying the files and rebooting. upon rebooting, the mobo makes a few beeps, the screen turns on and off, and when i can finally get it to stay on, it appears to be resetting over and over, showing the "Press any key to boot from disc....." message. I can reset the computer and if i press a key to boot from disc, it goes thru the setup process again and i run into the same problem. anyone have any idea why this might be happening? i wasnt sure about the HD because i wasn't there to buy it with her, so i dont know for sure that its compatible, but i have built a couple computers before and this problem seems very strange to me. any help is greatly appreciated! thanks..
