I was wondering if someone could help me. I have a p.c with the following, amd athlon fx55, 2ghz ram, 120 gb harddrive, 256 mb radeon x600pro, lan party nf4 ultra-d. I resently just bought all these parts and build my p.c, i switched it on and it all worked fine. Then i move the tower to where i wanted it and then went to switch it on and it switched on but there was no picture. I checked everything cables monitor and making the card was in properly, it didnt switch back on. I left the p.c and came back to it the next day and it switched on and i had a picture. Then i switched of and left it for an hour came back and switched it on and it powered up but again there was no picture. Is there someone that could give me a few ideas what could be the problem.
