Screen flickers, has stripes and wild colors - help

After repairs, this Toshiba Satellite Pro 6100 worked fine for months. I took it on a trip in my carry-on luggage and the video display has gone bonkers. The resolution is stuck on 640x480, but worse than that is the flickering and the stripes.

The OS is XP Pro SP-2.

I have searched the web for troubleshooting ideas or possible solutions. One possibility was that the video card connection is loose.

The control panel says the video card is operating normally.

Can you point me in the right direction?

Thank you.

When I see that I....

I reach for my Ubuntu LiveCD so I can boot that (we're not installing it) and test if the machine seems ok with a LiveCD.

What I do next depends on the test results.

Ubuntu w/XP Pro?

Can I use an Ubuntu disk w/XP Pro? If so, is a Live CD downloadable?

What is that?

Please explain what "an Ubuntu disk w/XP Pro?" is.

Yes you can download Ubuntu for free. I think you would google that.

Ubuntu w/XP pro

Sorry for the short hand ... what i meant to ask is this. The operating system on my computer is Windows XP Pro. Can I use the Ubuntu disk you suggested on the operating system on my computer? Ubuntu is Linux. That is why I am asking.

Thank you for your quick response. I apologize again for the shorthand.

Remember this is a LiveCD

It doesn't care what OS is on the hard disk. LiveCDs run on their own and this is why it's such a powerful test tool. We can test the machine without touching one data bit on the hard disk.

Hope this clears that up.

As to Linux, we don't have to know it's Linux. Read
That was 5 years ago and today, it's even better.

Ubuntu LiveCD -

The Ubuntu LiveCD is very cool and good to know, but it does not really help (at least not yet).

My sick computer boots with Windows XP. The screen now has very classy vertical pin stripes! I checked nvidia and toshiba's websites for upgraded drivers (my current one is the newest) and will continue searching for a solution - its too old to spend more money on at the repair shop. I want to try it myself, but need a little help on where to start.

Then we are off to the service shop.

The Linux LiveCD is our DIAGNOSTIC to see if the video card or rather motherboard is good or bad.

You've passed up my best diagnostic and headed right to a service counter.

Good luck, I hope they don't charge you too much.

Are you a little slow...

...on the uptake? The idea is to use the ubuntu cd to boot to, bypassing Windows completely. I know zilch about computers, but my guess is to determine whether it is an OS issue, or a hardware issue.

You ask for help, an expert like Bob responds, and you just blow off his advice.

Some people's kids...
