After increasing my vga memory my pc wont work why?
Several things I will have to assume. You have onboard graphics, possibly not enough memory, are attempting to watch high resolution videos, are using a desktop and are running Windows 7 and are watching videos from a DVD.
The fist thing to check is how much memory you have. Any less that 8MiB and your system will struggle. Also give the system a spring clean.
OnBoard graphics has many restrictions because it relies on available resources. To increase it's performance you should shut down every other app that is running, except essential like anti virus and sound of course. if you are capable you could set up a second user that has the minimum running and log onto that for video.
If you are an avid video watcher then an investment in a separate graphics card with its own memory would increase your enjoyment 1000%. The cost can vary so get the best your budget will allow. Even a low end card will make a difference.
The ins and outs on how to do all these things are beyond the scope of this site as it would require many pages and graphics.
As a summary you should.
1. Increase physical memory to 8GiB or more if you are running Vista or above.
2. Minimize resource sharing by closing non necessary apps (including email, browsers, instant messengers)
3. Upgrade to a separate graphics card
4. Download and run CCleaner. It is free and will clean out your system safely.
5. Reverse what you did in the BIOS settings
The other point is if you are watching downloaded videos make sure you choose a Standard Definition copy. eg MP4 or Divx
As far as your CD Drive is concerned it could be a number of things from a damage drive to lack of power source.
