hey guys, i have an old P4 that i cleaned out inside the case the other day, in doing so i think i broke the graphics card, so i got another cheap one.
the problem is that i still have no video when i turn on the computer.
i turn on the computer and everything seems to be working fine (no beeping from the motherboard, fans spinning, everything operational) but nothing comes up on the monitor.
the motherboard is a gigabyte P4titan 667 w' dual bios

I have disconnected everything and then made sure it was all back together but still the same problem, it was working fine before i cleaned it out.

can anybody think of what could be wrong?

thanks, luke
