have you tried changing your desktop picture too? simple but it might be that cos i dont think problems with the monitor would show up on print screen like veggie said

Are those lines random? (Show up different places?) If you Lock the PC (Windows Key + L) do they still show up?

When do they start showing? (during post, during boot, at logon blah blah)

Could the peple giving monitor related advice please not. A screenshot will show what gets sent to the monitor, and if the problem is at the monitor, it will not show in a screenshot, because the screenshot is taken before the information reaches the monitor.
