white screen

Upon starting up my HP Desktop Vista 64 bit I get a white screen. I can’t do anything, it just sits there…white.

I can get to safe mode command prompt , but I don’t know what to type in the box.

any help appreciated, thanks

It could be the cable, have a look here http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/

Thanks for the info , but this is happening on my desktop computer. Since it happened when I turned it on this morning, I have been able to get to the screen for system restore and restored it back a few days, before this happened to me. Hubby was looking at a joke site and the screen went completely white, no task bar, nothing. I am going to run Malwarebytes to see if anything shows up there.

Once again, thanks ;D
