Trying to get my son's computer working. He had a 2 Gig hard drive installed...and then I installed a faster (24X) CD ROM drive. Everything worked fine for a few days. Then, my son decided he wanted to install every computer game in the house. It froze up, to never boot properly again. The computer refused to detect the HDD after this. I got a replacement maxtor HDD (this one is 8.2 I believe). The BIOS will not autodetect the new drive. I have installed the parameters manually, and it seems to be recognized on the boot up screen, but will not be recognized when I try to format the HDD. The CD ROM drive is detected no problem. The drive is spinning up, and is jumpered as master, although I have tried all the other jumper settings as well. I have tried new IDE cables, tried putting CD ROM on a seperate cable, have tried replacing the motherboard (which didn't boot AT ALL...blank screen was all I could get..but hey, bought it on ebay, so who knows), and have made sure the other jumpers on the board are correct. I have taken out the CMOS battery, and have replaced the CMOS battery, but to no avail. Could there be something really simple I am missing here? PLEASE HELP I HAVE BEEN WORKING ON THIS SINCE JANUARY 2002!! Thanks
