can someone please help me with this?

"you know what happens" nope I dont, you dont describe the issue well anuf to be solved textually. And I use 3DsMax.

Whats your system setup ... it looks as you have a serious bottlekneck issue somewhere!

If your problem is rendering and nothing else I might suggest its the software to your graphics card thats gone corrupt, uninstall any previously installed software before, contact your vender and get the optimal drivers and reinstall the software. Remember to have completly removed any odl drivers to your Graphic Card, that serious damage may be done both to your MB and GC!

Sometimes a MB conflict with a given Graphics Card, so check both vendors for possible issues. 

Ever tryid to take all the hardware out and install each part again manually and also on a boot-per-hardware-installed-basis!
