Pixels reduced to 640x480 week ago on 16 colors.
Since then have tried:
Download / install new drivers (NVidia Vanta LT) / Restore to month earlier, then a complete restore to factory settings / Switching monitor and cable / Wiggle and take out and replace video card / BIOS check - (AIDA 32 said over 2 yrs old but compaq has no updates on site). Full virus check (-ve)
Exclamation mark by display adaptor but refuses to be deleted. Is it time to give up and buy a new video card?
Thanks in advance for any help.
Old sore eyes, Caro
