No screen at boot(bios), but turned on during windows 7

I have a 5 year old HP DV5-1021tx and I have a screen problem. This problem became permanent since last year but it only has occasional occurrence before.
When I turn on my laptop, the screen will not turn on until Windows is full loaded to the Welcome screen.
I have notice that since the problem became permanent I have lost brightness control in Windows 7 (brightness slider is gone in Windows Mobility Center or power options) as will as viewing dual screen mode (only the connected screen will display).
I have also notice that hibernation is missing and every time I put my Windows 7 to sleep, when it wakes up, the resolution is changed to 800x600 with black bar on the right and blurred task bar. The display returns to normal when I changed the resolution back to 1280x800.
Can someone help??
