When I started my computer today the desktop was pixelated and partialy garbled. When I open system windows it is better. Some windows like this one using IE at Geeks to Go! is OK. If it were a graphics card I would think it would be pixelated and garbled no matter where I was, desktop, IE, My Computer window, etc.

I tried refresh, changing desktop background .jpg. When changing the desktop background .jpg it cleaned it up somewhat but deteriorated again.

I am losted and need help. Please, any help with this problem will be greatly appreciated. Thank you.

Start the System Restore tool at a command prompt

1. Restart your computer, and keep tapping F8 during the initial start-up until you get options, select Safe Mode with a Command Prompt then press enter.

2. Log on to your computer with an administrator account or with an account that has administrator credentials.

3. Type the following command at a command prompt, and then press ENTER:

%systemroot%\system32\restore\rstrui.exe

4. Follow the instructions that appear on the screen to restore your computer to an earlier state.

Look for the most recent system checkpoint created before the errors to restore from

Keith,

When I try to restart the computer in safe mode with command prompt, I cannot enter %systemroot%\system32\restore\rstrui.exe or move the mouse. The computer freezes. When I shut it off and try again, the pixelization and garble worsens. So, I start the computer, change the desktop .jpg, use a program called 'cleanup' (it was recommended by Geeks to Go!), then the computer asks to log off/on I select yes. This cleans up the desktop (not entirely) and mouse pointer. The desktop gets worse with use.

I tried to restore the computer using, start, all programs, accessories, system tools, system restore. It reports there are no restore points, etc. I know I have manually set system restore points but they are gone.

HELP!

This is more or less everything you can do, this side of a repair install

Items in blue which are underlined are clickable to give more information about the process

Click start then run, type prefetch then press enter, click edit then select all, right click any file then click delete, confirm delete

Click start, all programmes, accessories, system tools to run disc clean up, then from system tools, run disc defragmenter.

Click start then run, type sfc /scannow then press enter, you need the XP CD and Windows File Protection will show a blue onscreen progress bar, when the bar goes, reboot

If you do not have an XP CD you can borrow a same version as was originally installed XP CD, if you downloaded SP2 then you need an SP1 XP CD

Click start then run, type chkdsk /f /r then press enter, type Y to confirm for next boot, press enter then reboot.

Windows will appear to load normally then either the monitor will show progress or the screen will go blank, do not disturb this.

This will take an hour or so before it gets to the desktop.

Download and install Tune Up 2006 Trial

Run Tune Up Disc Clean Up

Run Tune Up Registry Clean Up

Click Optimize and Improve to run Reg Defrag, which will take a few minutes and need a reboot. You should disable the antivirus programme to run this and check it is running after the reboot

After the reboot, click optimize then system optimizer to optimize the computer, select computer with an internet connection from the drop down menu, this also requires a reboot

After the reboot, click optimize then system optimizer to accelerate downloads, select the speed just above your actual connection speed, this requires a reboot

After the reboot, click optimize then system optimizer to run system advisor

Keith,

I will do what you have suggested.

I did get to a 'safe mode command prompt' and entered what you suggested, there are no restore points. Any ideas why the restore points are disappearing?

While in and getting to the safe mode and also restarting in safe mode my monitor is really crazy with pixelization, garbled screen, etc. When it gets to the desktop it is pixelated but you can make out the desktop. By right clicking and changing the desktop picture, it cleans up but the mouse pointer is like fuzzy and dragging icon text. To clean it up I run 'cleanup' then log off/on. I think it is the log off/on process that cleans up the mouse pointer.

I hate repairs, any idea what I can do to eliminate things before I repair?

Thank you.

If you get the initial screen then it goes nuts then you get XP logo then it goes nuts then it gets to the desktop, it can be monitor out of range, caused by:

The monitor resolution being too high

The video adapter drivers not working and making the monitor resolution which would ordinarily work, out of range

If you right click the desktop, click properties, click settings and set the screen resolution to 800 by 600 and click apply, the problem should go away

The restore points will hopefully be more amenable after you run the system file check

Keith,

I set the resolution to 1280 x 960 earlier with no results. I changed monitors Dell FP 19" to Dell FP 15", still has the problem. After hooking the Dell FP 19" back up and doing some other stuff (Cleanup, log off/on) the system is OK. It went click then it cleared up. So, I restarted the computer, changed resolution to 800 x 600, reset resolution to 1280 x 1024, rebooted and all is fine. I think maybe graphics card problems are in the future. Or maybe swapping out monitors chased the gremlins away.

There was no set pattern of what was pixelated and fuzzy. Sometimes the bios bar would look a little pixelated, but the windows welcome screen would be OK. When it was done booting and painting the desktop, the desktop would be pixelated, not lined up, fuzzy. The next boot would be different, but always finishing with a bad desktop. At first if you opened a window i.e. MS Word it would be fine, but I discovered over time it would begin to deteriorate.

Thank you for guiding me through this nightmare (I have no confidence in my computer reliability now). But, as Arnold would say if things go south again, 'I'll be Back".

Thank You for letting me know
