I have a Windows 7 system along with media center. I use it as a default option for my media files. I have attached a widescreen TV to the system so that I can view the same on higher screen. Now the issue is that it had stopped working suddenly. I rebooted the system and when I relaunched it was very laggy. There were certain Windows update in the background which were running. I need some option by which I can improve its performance. Will it be better if I re-install Windows back again. As it came with the operating system, I find no way to re-install it. Now the issue is that when I run some movies it takes quiet long time to show on the screen.
The second monitor simply turns to black. The cpu usage has increased to some extent. It is becoming slow day by day and I am not able to get the right way to make it work. Also when I press alt+tab to switch my existing window the desktop appears up very slowy. I am using a Core 2 Duo system along with 2GB ram. I have a 500GB drive in which almost 450GB is consumed by the video files. I need help to fix this as fast as I can. Thanks.
