My Asus x550ld xx82d working like a snail [ i7 4500u , 8gb ddr3, nvdia gt820m,1tb ]

[RaviYadav007]

Hi TomsHardware Experts , I bought the Asus xx550ld xx82d laptop, and for a few weeks it worked as bloodhound, and then it started lagging . Games like gta 4,and Battlefield 4 are lagging too much, and even low grafic requiring games like Call of Duty 4 are too laggy , they lag every 6th second (approxx).
Get me out of this situation ,its like Hell , and I don't want to format my Hard drive. I tried CCleaner and System mechanic to clean the junk files and defragment my Drive and to optimeze my PC, but of no use..
Please help me out of this .......
Thanks in Advance !!!!!

Uninstall the Nvidia drivers, reboot and reinstall the most recent GT820M drivers. It might be a good idea to download the drivers before uninstalling the old ones. You can find the drivers here:

Also, go into the BIOS and make sure the Intel HD GPU is disabled and PCI graphics are enabled. It could be running of the integrated graphics instead of the NVidia card.
