Okay. First my computer works fine today. next, i get another which has an amd athlon processor, and the comp i had had a pentium 3. Now i wanted to beef up my computer, so i took out the hard drive, video card, and sound card out of the computer i had, and put them into the one i just got.(current comp. runs 2000, new one runs 98). Now the 'new' computer worked fine without putting the things in. when i stuck the hard drive in the new one, it would not start up with both in, only when the hard drive for the 'new' computer is in ONLY. So then i decided to get the driver for the motherboard for the 'new' computer, and put it on a floppy. Next, i hooked up my original computer with all that it had before. Now the big current problem is that after it loads the screen with the 'F1' options, it goes to a black screen, with a blinking cursor in the upper left corner. That is all that happens. We cannot even get into safe mode. How do i fix this problem?
