I receive Aero Lag when opening and closing windows in Windows 7

What PC specs?

If it's irritating, turn off aero or turn down some features

-Intel Core I5 cpu 2.80GHZ 2.79 GHZ

-Corsair RAM DDR3 8GB (2x4)Kit 2133MHz Dominator Platinum

-Gigabyte Motherboard GA-P55A-UD4


-OCZ Vertex 3 Series 120GB SSD (2.5", Sata 6Gb/s, VTX3-25SAT3-120G)

-Amd Rhadeon HD 5850 1GB GDDR5

I would check drivers, or as stated, turn it off!

All the drivers all updated but problem not solved ..
