i have a 7yrs old desktop which my dad uses for his official works. it was great for his works till 3-4days back. now its just hanging and hanging too much. today i have noticed one thing. i was about to print a document from this pc. and whenever i was clicking the print option or print preview option in office 2007 pc was hanging. also when i was opening nvidias driver download page pc was hanging. now i disabled my graphics card but the monitor is connected to card,s vga port. but display was comming and all was smooth. no hang on office 2007 or nvidia driver download page. now i updated the driver and enabled the card but its again hanging on doing those things. again disabled and now not hanging. whats should i do now. i apparantly think my card is gone. is it correct???
