The monitor for no reason that I can think of shows up with numerous vertical coloured lines. When I re-boot it clears and will work as normal. But it again get filled with these linesand I have to re-boot. This has happened about five times.Once I clicked on a short cut to a web site, and immediately I heard a grating noise in the computer and the monitor went on the blink Is the problem with the monitor or the video card? The monitor is a View Sonic 20" LCD 2 years old My mother board is Gigabyte model 8SIMLH-P and is 5 years old. The video card is Onboard. Brand sis651. I realise that if I have to replace the video card I need to get an AGP card Is there a program I can run to check out all my hard ware Would appreciate help

Have you connected the monitor to another system or connected another monitor to the system you're having trouble with? "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

No I have not done as you asked. By the way, when I first got set up a long time ago I never turned it off had it running 24/7.I never had any trouble. But then I decided to save power I shut it down after use. Since posting this message, i have not turned the computer off, and so far the monitor has been OK.
