Boot up and System failure.

Hi, I am having a major problem with my PC. On boot up, the screen displays a dotted grid all over the screen. As the boot up continues vertical lines replace the grid. When Windows XP loads the screen can go blank for a time, and the whole system slows down. Also when I scrool with the arrows or the mouse the screen sometimes becomes garbled. I have fixed the MBR and done a system restore but the problem persists. Any ideas.?

 

Hi, and welcome to the BBS

I would suspect that you have a Video (Display) problem.
Are you using onboard VGA or a Video card.
If you are using a card try re-seating the card or if possible try another card, sometimes updating drivers might help as well.

 

Thank you for your reply. I have a NVIDIA GeForce FX 5700LE Card. I will do as you suggest.

 

I hope that you will see a positive result, if not I am sure that you will receive, more support in trying to solve your problem here.

 

The only other things I can think of is to clean the gold connectors on the card with a soft pencil eraser. Check that the card is seated squarely and bolted in tightly. If the card has a fan, check it is spinning freely when the system is running.

No luck, try removing any added hardware (eg, PCI cards).

Look at getting it stable at startup first.

Thanks, that seems to have solved the problem.

 

Thanks for your reply, it was a video card problem, and it is sorted now.

 

Ahh good. Thanks for letting us know.

 

great to hear that you are back on track.

That's what happened to my laptop as the nvidia chip ******* up. Guess it has happened to many others due to an overheating problem revealed in nvidia chips.

 

Thanks for your reply. A few other members pointed out the problem, the video card. That was the problem, however the problem still exists although it is intermittent, I am not sure if the problem lies with my motherboard or my video card.

 

Adrianv: Do a search on the web about this. Read this and other reports. The problem effects computers that get hot. Many are not listed by HP:

My pc did exactly as you describe. Eventually, the reheating of the chip gets worse and then "ka putt! "

 

Thanks for your reply. When you say the chip, is it the video card chip you are referring to, and if so replacing the video card would sort out the problem for good.? Adrian.

 

I wish I knew. I was under the impression that the Nvidia chip was in my laptop somewhere and not on a "video card" somewhere. Let me do a search...
maybe you can find an answer here:
