I logged in last evening and my screen was fragmented and unusable.

I am using Phoenix Firestorm Viewer.    After relogging several times with no improvement, I did a clean reinstall.   The problem remained.   I tried 4 times to reinstall but still have the fragged viewer. 

What is wrong?

Thanks for that.  I tried it but it didn't work.   I have cleaned out everything and downloaded the viewer again but it is still the same.   I have downloaded the SL Viewer and that is working fine.  However, I would still like to be able to use the Phoenix viewer as well.   Is there anything else I can do to get a clean version?

 Thanks for answering my query but I'm afraid I have no idea how to do that.   

 

Thanks Lindal.  I did everything you said and there was an update which I downloaded.   It didn't solve the problem abd I daren't change the graphics card in case I **bleep** it up.  My computer is new so I'll wait till my friend visits next week and get him to do it.   Meanwhile I'll use the SL viewer.

1- Please make sure that you have the last version installed (updated)

2- Clean your cache

3- Restart your viewer 

4- Reinstall you viewer

5- Check if your graffics are compatible with Second Life Game

6- Contact second life support -  https://support.secondlife.com/history

That looks like your graphics card is either suffering from a GPU overheat or that you may have allowed an automatic video driver update to occur and your GC didn't like it very much. [Your GC may be working OK for standard color management chores but once you start SL, it needs to allow the GPUs to really do their thing]

Try rolling back the video driver to an earlier version.

If this is still happening when entering SL then try cleaning the Graphics Card cooling fins of dust and make sure that the fans are all working correctly.

Here is how to update your graphics card drivers.

First, see what graphics card you have!  The easiest way to do this is to open your viewer.  At the login screen, go to Help/About Second Life (if you use the Firestorm viewer, it will say Help/About Firestorm.)  When you click this, you will get a screen with a lot of information about your system.  It will include some information about what graphics card you are using.

The two most likely results will be either Nvidia GeForce GTX, or AMD/ATI Radeon.  You might also see Intel HD Graphics XXXX.  Depending on which one you have, go to one of these websites.

Nvidia: http://www.geforce.com/drivers

Radeon: http://support.amd.com/en-us/download

Intel: https://downloadcenter.intel.com/

NOTE:  Given the large amount of pink in the image you posted, my guess is that you have a Radeon card.  The latest drivers for these cards do not work well with Second Life.  Search the download site to find earlier drivers.  You want to install the version 14.4 drivers, which are known to work well with SL.

Be sure to also follow the advice about opening your computer case and checking for dust, and making sure all fans are running.  The best way to deal with dust is to use a can of compressed air to blow it out.  

You can also check the health of your graphics card with a free utility, GPU-Z.  Download it here: http://www.techpowerup.com/gpuz/
