Blank screen before OS select screen

[thegauraw]

more than 15 sec of blank screen appears before the OS select screen loads in my computer.....
Please help me remove this blank screen.
It was fine some 15 days ago..... as soon as... the power was turned ON, the OS select screen appeared.

If something was fine and now it isn't we usually look for changes. Did you install any software or change anything?

Can you check the Windows update history to see if any updates were done around the time the problem started.

It might be that W7 is looking for a display in that time..

Try doing a system restore to a point in time before you had this problem... if that doesnt work, do a repair install... Hope this works.
