Hi guys,

Hopefully I'm posting this in the right place. This is my first time to Bleeping Computer, but I'll try to be clear and to the point with my issue.

My OS is Windows XP Pro



This is the problem I'm having:

Posted Image


I downloaded and installed a screensaver about 3 weeks ago. Everything seemed fine at first, but then a few days after that I started getting these distorted bars of color flickering on my screen. I removed and deleted the screensaver program, but the bars have since remained.

The severity of the distortion on my screen varies from barely noticeable artifacts, to the bars like seen above, to a thick pixelated haze that distorts the entire screen. Sometimes it gets so bad I have to restart the computer because I just can't see what I'm doing anymore.

Here's what I've tried so far to fix the problem:

1. Checked the monitor connection to ensure it wasn't loose

2. Checked the pins on end of monitor cable for any damage

3. Replaced monitor with the working monitor of another computer (distortion remained even on new monitor)

4. Plugged in a second monitor into second monitor port (distortion then showed on BOTH screens)

5. Re-installed display driver

6. Ran a registry repair tool that fixed about 463 things within the registry

7. Changed the Hz for monitor in display settings (this at first actually cleared it up, but the problem returned later - and now doing it tends to just make it worse)


None of these things worked, unfortunately. I honestly don't know what the problem is, but I'm suspecting that screensaver did some damage because it is the only thing I've really installed recently and the problem started almost immediately after. Now the thing is that computer has not had an internet connection for over a year. The antivirus and spyware programs are seriously out of date (AVG and Spybot Search and Destroy). I figured that wouldn't be a problem because normally I just use the machine for working in graphics programs and never install anything "foreign" to it. But stupid me had to spice things up a bit with a flashy new screensaver and, well, things got a bit TOO spicy. In any case, I figured if there was a piece of malware in this screensaver then mr. computer's outdated defenses would probably be wide open for infection. That's one theory anyway...

I did run a scan with both AVG and Spybot just for the hell of it and, of course, neither found anything. But I'm just shooting in the dark now, I really have no idea what's causing the problem. I'm coming here as a last resort to see if we can't get to the bottom of this. I know there's a lot of bright and caring people on these forums and deeply appreciate any help that's given.

I hope I've been clear enough about my issue without rambling too much. To sum it up I just want to know what's causing the screen distortion (i.e. is it malware or something else) and, if possible, how to fix it.

If you have any questions for me just ask and again any of your time is greatly appreciated. I will patiently stand by for a response.
All the best.

Is it malware?
I don't believe so, but as long as you're here let's double-check

:trumpet:
The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware Free version and save it to your desktop.

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.


alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
---------------------------
Be sure to re-enable your AV and malware scan tools if they were disabled

=======================

:flowers:
Please download TFC by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
==================

:thumbsup:
SAS, may take a long time to scan
Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
    First
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Hi garmanma thanks for the response.

What I should have been more clear on with my initial post is that the computer I am having trouble with has NO local internet access. I use it as an offline workstation only. Anything I need off the net (which is rare) is taken from another location and transferred via usb memory stick. The lack of internet connection is the reason why the anti virus and spyware programs are so out of date.

I see in step one of your response that the troubled computer requires internet access to use MBAM. Is there an alternative process that would not require internet updates?

If not I might be able to move the computer to another location temporarily and get it connected. It just might take me a day or two.

Thanks again for your assistance with this.

Hold on, I just re-read your response and caught that there is a way to download and install the updates manually. I'll get right on this :thumbsup:

Also, just another detail I forgot to mention, for what it's worth:

In addition to the bars across the screen a couple times during startup, I would get this black screen with rows of colored characters and symbols (random numbers, letters and arrow symbols) going across horizontally. I would offer a screenshot of this, but it's only happened twice so far and missed the chance to grab it.

I don't know if that helps in your diagnosis or not, but thought you should know about it since it's occurred only during this problem.

I will get back to you after going through the steps.

Also, during one of the reboots, I got the rows of colored symbols again. I hit the Print Screen key to grab a picture, but when I went to paste it into a graphics program there was nothing on the clipboard :flowers: :thumbsup: hmmmm...

Do you have the program POWERREG SCHEDULER installed?

Everything you say is happening leads to a bad video driver or card/chip
You said that you downloaded the driver. From where?
Are you sure it was the correct one? there are 10 of them that I'm looking at
Anyhow:

Update mbam and run a FULL scan
Please post the results

Hi garmanma,


"Do you have the program POWERREG SCHEDULER installed?"

I looked within Add Remove Programs on windows and did not see anything called "POWERREG SCHEDULER" in the list. Checked in the program files folder too and did not see it there either.



The driver being used is "ATI FireGL X1" version 8.163.1.0 - that's what it shows in the device manager. That's the same version I've been using for the last 4 years or so and never had any problem like this til now. I go straight to "ati.com" for any updates.

After the distortion problem had already appeared (but before coming here), I did try to install a newer version from the FireGL X1 list of the website, but the installation failed due to "no compatible drivers found" within the installer. I just looked at the install file name now and it had "FirePro" in the name instead of "FireGL" like my older ones. Perhaps it was the wrong driver. It didn't seem like anything was installed or changed, though. And if I look at the driver being used right now it shows the same old version as always.


Anyway.


Here is my new MBAM report:

Malwarebytes' Anti-Malware 1.44

Malware-wise I believe there is nothing wrong with your computer
I would suggest that you start a new topic in the Internal Hardware forum
