Contrast issues, grey crash screen with the Intel gma4500mhd

Hopefully this is the right place to post this, if need please move it as needed. I have an Intel gma4500mhd graphics controller. For a long time now, the computer has done this wierd thing where when the computer loads, the display comes in and the colors are all a bit off - mostly having to do with contrast. All the icons are a little too bright, and on some websites, greys are not shown. I was always able to fix this by going into the graphics control panel, changing a setting, applying it, and then changing it back (it was like it reset the colors) and everything would go back to the right colors. I recently upgraded to windows 7 - and this one issue I had both before and after the upgrade. Now that I've upgraded, I'm having a secondary issue where whenever I'm away from my computer for a period of time and it goes into sleep or hibernation mode, I come back to use the computer and upon waking up, I get a grey crash screen. I know the functionality of the computer is still working as I hear the dings and beeps like when an email comes in, but the screen is completely grey and I have to do a forced restart.

I have the current drive set for Windows 7, 64 bit installed -

The problem has been getting worse and I'm having to restart my computer multiple times a day so I'm trying to figure out what could be wrong. Any ideas??

Thank you!
