Hello, a week or so ago, the whole monitor's display went pink. Then it was ok, now it's completely pink again. Everything else seems to be running ok, e-mail, Internet. It's pink as soon as it starts booting up. Any ideas?

Thankyou.

See if it is any different in Safe Mode.

Try booting into Safe Mode:

After the power-on and BIOS POST or your Logo screen repeatedly tap the F8 key or hold the Ctrl key before Windows starts.

Thanks Jephree but Safe mode is exactly the same problem.
