Hello,

If I am in the wrong forum, could someone please redirect me?

As I write this my screen is breaking up with increasing numbers of roughly 5cm and 10cm long horizontal lines. This happens after the computer has been on for a few minutes. The screen also blacks out and then comes back to life. If I turn the computer off for a while and reboot I get a few more minutes of a readable screen again, as if cooling down is beneficial.

I have a Dell Dimension 8200, P4, 512MB, 64MB DDR Nvidia Geforce3 Ti500 with TV Out, bought in February 2002.

Does anyone know what is likely wrong? Age of graphics card, hard drive? The computer is making a bit more noise than usual, a sort of deeper whirring sound.

Your help is much appreciated.

Thanks,
Niki

Have you tried checking the monitor settings?
Has your monitor been bumped around lately?
Make sure the video card is fully inserted into it's socket, and the cable from the monitor is fully seated in the socket.
Check the end of the monitor cable and make sure that there are no broken or bent pins.
If you have another monitor, try it, and see if the problem persists, if so, then it's probably the video card.

Try running it in Safe Mode.

If the lines are not present, the problem is probably your video card.
If they are still present, it's probably the monitor.

A louder noise could be one of the fans starting to fail, causing it to overheat. If you can, open the case and try to pinpoint the noise. Have you ever had it apart to clean out all the dust bunnies?

Thanks everyone,

Sorry for leaving it so long to get back to you, was concentrating on getting another system up and running and all my settings, files etc transferred before the s**t hit the fan.

Talking of fans, I ran the computer with its guts exposed and had no lines appearing, closed it up and they came back pretty quickly again. So I had a closer look inside for fans and found that the graphics card's fan was simply choking on so much dust, it looked like fur. I haven't been up and running that long yet but at the moment I have no lines. Will surely let you know if they come back.

Appreciate the support very much,
Niki

Hello,

Back again! Unfortunately, the lines reappear when I close up the back of the computer. If I keep it open, they stay away. I checked the fan and it is working OK as far as I can see, I even removed a PCI card adjacent to the graphics card but it still seems to need the back open in order for enough air to circulate and for the graphics card not to overheat.

So, my question is, is it possible once a graphics card has over heated enough or enough times for the card to spoil in the sense that it needs extra ventilation to keep it cool enough to run normally? Could I have passed some threshold? Or, can there be some other reason the card is overheating? I am making an assumption that this is the problem I have but it just seems that way to me - the times the lines have appeared and finally the screen has blacked out on me, the graphics card was simply boiling hot.

Thanks for any help you can give.

Niki

Is there a heat sink between the fan and the chip, and if so did you clean any dust out from between the blades of the heat sink? Perhaps the thermal contact between the heatsink and the chip has "broken".
The power of accurate observation is commonly called cynicism by those who haven't got it.
