PC : 1.5gig AMD Athlon, 256 RAM, 32MB SiS 300/305, 35gig HD. I am trying to install this new graphics card ive bought nvidia geforce MX 4000 but i have a big problem. Firstly even though in the manual it says it is compatible with AGP2x/4x/8x slots it wont fit into my AGP4x SLOT! (after i remove my previous card). Infact it only fits into the PCI slots that i have. Ok after i uninstall old drivers, put it into PCI slot and screw it in.. i turn my computer on the monitor do not receives any signal from video card. Infact the red light (signalling hard drive access) doesnt even come up meaning that nothing has started (not even BIOS).The only light i see is the green one signalling power to the PC. THen i remove it and install my old card and everything is OK! Why is this happening to me P.S-maybe i need to download drivers for PCI based cards?

my MS-DOS is fked up.. and i keep getting the same message when trying to install some old games (half life): Quote: C:\Windows\System32\Autoexec.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application. there is a solution to the problem here but when i go through the resolution steps and do everything, i still have the same error msg come up (ive done the steps about 5 times over and still nothing). can anybody help me?
