    Yesterday my dads computer - an old Packard Bell - wouldn't show anything on the monitor (a message saying 'no video output' was displayed). All I get is a blank screen, not even the BIOS splash screen shows up. This is when I have the DVI cable connected. If I switch to VGA, the monitor will show vertical green/blue lines flickering all over the screen.

    The monitor itself is working (I've tested it with my laptop), hard drive is functional (swapped it in an external case I had), and I assume the PSU and CPU works as the computer does power up and passes the POST (giving the normal one short beep). Sometimes it'll reboot itself within a minute or two, which I guess is due to BSODs when getting into Windows.

    I've tried resetting the BIOS by clearing CMOS/moving jumpers and taking out the RAM sticks and booting with one at a time in different slots. Didn't seem to work.

    So I've narrowed it down to the graphics card (as the motherboard does not have integrated graphics). Unfortunately I don't have any spare cards I could swap it out with.

    Before I go out and get a cheap low-profile card, is there anything else I should try or check? Does my conclusion seem reasonable given the symptoms described?

    Thanks in advance.

    It does point to the video card
