My computer had been working fine of late, but a few times in the past 6 months I have turned it on and the monitor will show a message: 'No Signal'. Eventually, after many tries it would usually connect once more to the monitor. When I tried to restart my computer the other day I could not get the monitor to come on except for "no signal". I took out the RAM and replace it as sugested in a prvious message but this didn't work. I have a custom built computer with an Intel D865PERL motherboard and a pentium 4 processor (~ 3.0G)and 1.5 G of RAM. The computer was built in 2004 and supposedly had state of the art equipment.
Is ther anything I can do or do I have to buy a new computer?
