So I just got done replacing the motherboard & power supply on my Dell Dimensions 4600 a few days ago. I replaced them because they had burned up and my computer would not even powerup (a new power supply did not fix the problem). Anways... I have new problems now... So, it booted fine for a few days and worked great after i had replaced the MB and PS. Then today I get a couple "blue screens of death" that made me restart a few times. I also got a few windows errors when I tried to open My Computer. I didnt think they were that big of a deal because i had gotten these errors before with no following consequences. Now, after the 4th blue screen of death and 4th time restarting, it won't restart. It simply goes to a blank screen after the Dell bios splash screen appears. I have 2 maxtor hard drives- 80 gig and 20 gig. I have not made any changes to my computer in the last few days. For RAM I have 3x128meg and 1x256meg. I already took out my harddrives and made sure they were connected correctly- both are set to cable select with the jumpers. I am real close to formating the HD and reinstalling windows.... Any help would be greatly appreciated!
