Windows 7 SP-1 is running very slow ..........

Thanks for reply sir , Don Bradman cricket is now working well at 1024*768 screen resolutions and Suggest me some tweet to speed up my system and increase my windows experience index value without buying external hardware for the time being.
In my company we are going have a game shows where I need to play Need for speed most wanted along Don Beadman cricket, Don Bradman is now fixed but Need for speed still lags it is already running in small resolution and other problem it lags too much and takes in time for processing when I go for LAN play particularly. NFS carbon goes with my system but this old version NFS doesn't

Hi, have a look at the bellow website:

system requirements for your games:
Don Bradman Cricket 14 system requirements | Can I Run Don Bradman Cricket 14
GPU comparison:
PassMark - Video Card Performance Comparison[]=2&cmp[]=1279&cmp[]=1425

I think you have Intel HD 4000 graphics which is about the same as Geforce GT 520 (minimum required for cricket game) but it is also 40% less of what is required for NFS (Geforce 8800GT)

Unfortunately the problems you have are not software related they are graphics card related. The one you have is not powerful enough
