Hove the system appears not to see my display adapter which I suspect is the cause of a very sluggish display - especially noticeable in scrolling through a large worksheet.
Display adapter does not show up under device manager. Add new hardware scans for display adapters but does not give any way of installing one.
How do I get the system to see it again?
(I was infected with a few things but have run all the stuff under 'if you suspect malware' - and some other scanners - and the system is now clean.
thanks in advance
