I am using P4, 2.8 Ghz, 40gb, 512 mb, MSI Turbo cache VGA card (PCI Slot).
It has been working fine since a year and a half but yesterday when i plugged new monitor in with my pc, it said NO SIGNAL. I replaced the monitor with old one (which was previously working fine) it also said NO SIGNAL. Please note that i was connecting the monitor signal cable to the usual motherboard slot for Video. Later i tried with connecting the signal cable to the slot provided in VGA card, the monitor started working fine.
Additionally, when i removed the VGA card, monitor started showing something but didnt fully load the Windows and was taking long long time so i had to shut it off.
I am writing this question from the same system but i am little confused. Why the usual motherboard slot for video is not working. I think there is something wrong in the PC that can cause harm in future. Please help me!
