Failure to Boot - White Screen when powered on

[rnikula]

My machine has developed an issue. When I power it on, all I get is a white screen. A few times, it would would start up but now its always white screen...

The basic functions work, but not graphics or sound. I checked the various connections for something loose and didn't run across anything. It also is not showing any error codes.

Any suggestions on what where to check?

My guess would be loose connections but it sounds like you have already checked that. Hopefully someone will be along soon with more ideas.
