Specs: Windows XP

I have a fujitsu laptop with win xp. I do not know why but when I boot it, I see horizontal bars on the screen which make difficult to see the screen content. I even see those bars after windows gets booted. So, do you know why this might be happening?
I guess it does not have to do with viruses or drivers because it happens even before loading windows xp. Might this be related to a ram memory problem? If that was the case I guess I just would have to replace the ram module which is not difficult. The laptop just has one ram memory module. So how could I make sure that the problem is related to ram without buying a new ram memory module?

Might this be related to a video card problem? Is it easy to replace the video card? How could I make sure it is a video card problem before buying a new video card to replace the broken one in case it weren't really broken?

Are the laptop video cards standard in the sense that I might use an old laptop's video card with this Fujitsu laptop to check whether the videocard is the one causing the problem without having to invest in a new videocard?

First hook up and external monitor. If you get lines there, your adapter is shot. If not it may be the screen itself. Neither is an easy fix.

Regular ram rarely cause this kind of problem.

There is a program I use called CheckIt Suite for trouble shooting because it doesn't use any operating system to do hardware checks, so even if you can't boot into Windows, you can do checks on your system's hardware.

Problem is, you gotta pay for it: http://checkit-diagnostics.software...

Don't get the Amazon Netbook version, as it is not the same, although it may be a good at what it does.

But this part, CheckIt Portable Edition is the thing to you use from a cd/dvd boot device.

Chuck Norris was once asked why he doesn't use an iPhone, he responded, "Same reason I don't use tampons."

You could use a memory check program to verify that RAM isn't the problem. Memtest 86+ will run from a boot disk. Get it at the link below.


I agree with the comments by seawatch above.
