Hi, please help me with this, A friend of mine got a used system that was operating just fine, it is an older system heres the specs... intel P4 (socket 423) 1.3 GHz PcChips m920 board 512 Mb pc133 sdram 300 watt power supply 40 GB maxtor HD Geforce 4 MX440 agp 4x card ok heres the problem, he wanted to upgrade th evideo card, so we took the one out of anothe rputer he has, the card is a chaintech geforce fx 5200 256 mb agp card. Once it was installed, and we made sure it was seated properly and checked everything else, we tried to boot.....nothing, no beep codes or anything. The fans came on, the drives started up, but screen stayed black and no boot. So, just to double check we put the mx card in, and it booted. I know there is the AGP comp driving settings in BIOS, and it was set at auto. Do we maybe need to adjust that? And if so, to what? thanks in advance.
