Welcome
Unisntall the printer and see if the problem still occurs. If it does the reports show variious drivers as the cause. You graphics driver came up quite a few times, update. Your network driver came up, update that too
If none of that works, I would try a driver verfifier to rule out hardware. If the verifier is negative its hardware and we shall go from there.

Driver Verifier

I'd suggest that you firstbackup your data and then make sure you've got access to another computer soyou can contact us if problems arise. Then make a System Restore point (so youcan restore the system using the Vista/Windows 7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....AllPrograms...Maintenance...Create a System Repair Disc - with Windows Vistayou'll have to use your installation disk or the "Repair your computer"option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click"Next"
- Select "Select individual settings from a full list" and click"Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click"Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to useyour system normally, and if you know what causes the crash, do thatrepeatedly. The objective here is to get the system to crash because Driver Verifier isstressing the drivers out. If it doesn't crash for you, then let it run for atleast 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from yourinstallation DVD to set the system back to the previous restore point that youcreated.

DriverVerifier - Enable and Disable

You are very welcome. If you have questions or new problems, you are always welcome.

See if you can do it in safe mode.

Download and run ccleaner. Then boot then try to remove. This will remove remnants of programs that are blocking the path. If that does not work
go to search and type device manager in manger try to uninstall from there.
Finally try Driver Sweeper
