As I said HELP! Popped out for 2 mins this afternoon, came back to find that PC display wasn't working. Re-started, and NO DISPLAY. Took out Graphics Card, booted fine with built in graphics chip. Cleaned out the slot, tryed again - still not working. Took another PCI=E card from 2nd PC, and tryed with that - still not working. (But 2nd card is working on 2nd PC). Did a BIOS flash update. PCI-E still not working! So before I purchase a new motherboard, is there anything else I could possible do? Specs:- AMD 5200 (Duel Core) 3 GB Ram AS Rock Alive NF7G-HD720p R5.0 - Motherboard HD 4850 G/Card - Was working fine up till this afternoon!
