I have a great Sony Vaio laptop running Windows 7 Pro - no problems until today. I had a screen freeze, after reboot Windows looks strangely white! I cannot see graphics in Powerpoint or Excel or shade cells. However I can view the presentation and the graphics are there. Also no graphics or background colours in IE. AN occasional inconsistent error box "Failed to create an IPC port" appears - note I am not running any copde, so this must be Windows code.
This appeares to be profile based. When I create a new account and login to that, all is well - it's just my own accoubnt which may in some way be corrupt. ANy way of fixing it, please? Should I reinstall WIndows?
