Alright, I just want to say thank you in advance for helping me. So my PC was working fine, I had a 40 gig hard drive in it, and finally had enough spending money to go buy a new 320 gig SATA hard drive. I installed the SATA hard drive, and debated whether to go XP or Vista, and in the end decided Vista because I had enough space to use Vista restore and stuff. So I installed Vista fine, my hard drive worked and everything, and about a month later Vista broke on me (for reasons which do not matter) and I decided to go to XP (Pro w/SP2). So I installed XP, and got to the point where it starts copying system files. And then it copied all the files, and goes to restart itself. (I leave the XP install CD in after it restarts) and when it says "Press any button to boot off CD" I get about 4 little . . . . and then I get little, colored squares on my screen, approximately 6 of them, just randomly placed on the screen. So its a black screen, with "Press any button to boot off CD . . . . . _ " and a purple square here, and a green one there, and a blue one over there, just strange. So I took the CD out, tried to restart it again, and when its supposed to boot off my hard drive, I just get a flashing cursor, I tried and tried, probably 10 times, and finally gave up and installed Ubuntu. About a week later I gave up trying to learn a new OS, and tried to install XP again, still doesnt work, yet I can install Vista perfectly fine. So, my problem is that I cannot install XP, because after it finishes copying files to my HDD and restarts, it wont boot. If anyone could tell me or give me clues as to why it is doing this, or what I can do to fix it, please do, help is appreciated. Thanks!!
