Experienced help needed!
That sounds like a video problem (i.e. hardware), not a malware (software) problem.
Sounds like a computer or monitor problem to me. But then, I know jack nothing.
You don't have a magnet up there, do you?
I can not offer you any advice in this matter, however if anybody has set up a repeater to work with a uVerse router let me know.
Could be a ribbon problem.
Try windows offline defender tool.http://www.thewindowsclub.com/windows-defender-offline-download . It will boot to the CD. That way if you are still having the problem when you boot to it, it is probably hardware or your video driver is corrupt.
Get Malwarebyte.
It’s the best and lightest there is for new dirt.
I have one that is experiencing video and LCD screen problems. I have investigated and found that this model and others have problems like this after a few years. For now, mine goes away when it warms up.
In your case, to definitely determine hardware or malware problem, take an image of your hard drive and store it on an external USB drive. Then format the drive and do a reinstall of WinXP....or simply install a copy of a Linux distro. If the problem persists, it's hardware. Get it fixed and then re-image your hard drive with the image you put on the external USB drive.
Macrium Reflect is free imaging software and easy to use.
Multiple possible answers, depending on whether this is a consistent problem, or varies with time.
If this is happening essentially immediately after boot-up (from a cold machine), then it wouldn’t be a heat problem.
If the color changes are limited to certain portions of windows, then I would indeed suspect some sort of malware, but even that isn’t necessarily the case, as it could involve an issue with certain operations of the video card.
If the changing colors are over the entire display - to one degree or another, then it would tend to point to the video itself... and unfortunately that means you may as well go shopping... though Black Friday is just around the corner!
If this is the Latitude C640 model, then I’d say you’d gotten your money’s worth!
Try this: get someone to steal the laptop, then use the insurance proceeds to buy a new one. That will work better than dealing with Dell customer service. :)
Looks like your VGA card is a problem. First try to re-install graphic driver, if problem remain same, replace card.
Or you can test, reduce acceleration and see whether that change display.
I use Spybot and follow up with Malware. that tends to clear all things.
Last week Spybot 6 and malware got 3.
The week before, running malware first it got 2 and spybot got 2.
Keep it up weekly, it needs to be done regularly and don’t forget to update your programs, there’s new stuff coming out daily to disrupt/crash your computer
Any possibility of taking a screenshot and then posting it here on FR? You can upload image to Flickr (or similar) or Jing and post the image or link here if you know how. You will get a much more accurate answer from the geeks here on FR.
Rainbow graphics? Your computer has come out of the closet and is now proudly proclaiming to be gay. Attempting to reprogram it to a straight OS is a hate crime and the ACLU will have you in court. Get rid of it before it insists that you pay to have the gender of it’s ports changed.
Graphics card failure. I had the same failure on a D series Dell Latitude.
Hook the laptop up to a monitor and see if the display is OK. I am betting hardware issue.
