My computer only shows a blue screen with writting all over it

You are getting a blue screen of death - if there is white scripting ( writting ) with the blue screen your operating system is corrupt reload your XP Pro.

I have a blue screen but no information. How do I get it back to showing my calls waiting. Yes, I have call waiting. Tony

Try doing a operating system Repair kind of like installing windows again but without erasing all your data. THis should bring it back to its original settings.

The blue screen of death usually means that there is missing files that prevent windows from starting up. Re-installing windows will probably fix the problem.

Try tapping F1 or F2 right after power on. This should bring up the BIOS screen. If it does, look for an item called "restore factory defaults" and select this. The info stored in CMOS may have gotten lost and without it, the system doesn't know what to do after initial hardware tests.
Check back and let us know what this brought (if anything.)

keep on preveiw mode and connect

try switching the plug ins ( the colour wires9red,white,red)

I do not have this particular model, but I am sure the fix is the same.

Go into the setup (press the screen when a map is showing)
Press the Blue Wrench (this is "change preferences")
Use the right arrow tro scroll to the screen with the flags icon. You can change your language there. As you can see, there is a lips icon which changes the voice; that is why you can have the voice and text in different languages.

1) unplug power cord for 10 minutes
Then when booting
2)Try setting your BIOS back to default
3) Remove all fittings on M/board except foot Video and memory. Including hard drive DVD CD etc and see if computer boots if it does try fitting others one at a time (with computer off of course )rebooting each time
These are only some suggestions to define if M/board is OK

i suspect the cpu and or fan is defective
