striped screen - monitor or video card or motherboard

by 3ring.circus / October 30, 2007 2:07 AM PDT

my lcd screen is fine upon start up and stays good for about 10 minutes, and then multi-colored vertical stripes form over about 20 seconds and remain. I restart, but the problem doesn't go away until the computer sits for several hours.

It's a P4 running XP and the LCD is about 6 years old, off-brand "SYS"

Is this something to do with heat build up that's affecting one of the components?

It's probably the monitor

It's probably the monitor, since that sounds a lot like pretty classic LCD failure. Usually it's a horizontal stripe that occurs, but if it's an older monitor, they might have laid the LCD strips out vertically.

That sounds like magnets.

It sounds like what happens if you run a magnet across a screen. Are there any type of magnets or devices containing magnets that are sitting fairly close to the monitor? I'd start by checking around and removing those, if there are any. I don't know if magnets would affect an LCD monitor like they do with CRT, but it's a possibility.

Another possibility is the monitor, being 6 years old, may just be wearing out and this might be a sign that it's time to invest in a new one. It doesn't usually matter what brand a monitor is as long as it works.

apparently not the monitor; how do I check the video card?
by 3ring.circus / October 30, 2007 1:46 PM PDT

I hooked the monitor up to my laptop and have no problems, so the monitor is apparently still good. Is it likely to be the video card - and is there an easy way to check it - or should I just replace it for the $60 or so for a basic video card?

Thanks in advance.

It couldn't hurt.

If you have a different good monitor you could plug that one in to see what happens. Most likely it's the video card or its drivers. Have you checked to make sure you have the latest drivers for your video card? If that doesn't work, try rolling them back. If still no luck, it's probably best to change the card.

Am I correct to assume the video card is also 6 years old, like the monitor? It might not be a bad idea to open the computer up and make sure there is no dust build-up inside, especially around where the video card is plugged in. Canned compressed air will get into crevices you can't.

Let us know how it's going.

It does sound like a video card problem ...

and from your description it might just be heat related.

The heat sink and/possibly the fan if so equipt may be dirty and a cleaning might suffice.

You might check to see if it is heat by opening the case and directing a floor fan into the case - if the problem goes away you know it was heat and can either get a new fan for the card, clean things up, replace the card (or just keep the floor fan running Happy ).
