Hi everyone!! My pc had been running really slow and I had heard that by having too much RAM (2GB) could do this, I can't see how!! But anyway I changed the RAM back to 1GB,, but it was still was running slow... Knowing this I then put it back to 2gb... But now when I boot it up it sounds like all the fans are going but it says 'NO SIGNAL' to the monitor... :_( Any ideas please.. Many Thanks,,
