Windows 7: Mouse lags on Windows 7 x64 when initiating graphics

Windows 7 Ultimate x64
Mouse lags on Windows 7 x64 when initiating graphics

Hello! My configuration is: CPU: AMD FX8350, MB: Asrock 990fx Extreme3, Graphics: MSI HD R7850 Twin Frozr 2GD5/OC; 16 GB DDR3 1600 Corsair; Hyperx 3k 120 gb SSD + WD Caviar Black 1TB HDD; 700W Cooler Master GX 700 Lite PSU.

I have a full HD monitor and a full HD TV, both conected to the PC. Problem is, after Windows 7 Ultimate x64 starts up, if i run a program that requires any form of graphics acceleration... like for example Google Chrome, the mouse will lag for a couple of secs. If i try moving it... it jumps until it reaches de desired position. This happens when i have both monitors connected to the PC and it only happens ONCE per session. After a couple of secs the lag stops and it won't do it again until next time i turn on my PC. I also tryed it with a HD 6670 video card... it behaved exactly the same. I am beggining to think it's related to the refresh rate... i noticed that if i try changing the refresh rate manually... immediatly after i do that, the system and the mouse will lag for a couple of seconds as i described it earlier. I don't understand why it does that, both displays are set to 60hz refresh rate... Any ideeas? It's really annoying ... Thanks!

Are you sure your drivers are proper and up to date? I take it your using HDMI for the TV and DVI for your monitor? Does that issue only happen with programs on your SSD, HDD or both?

All the drivers are up to date... The bios as well. Yes, the monitor is connected through DVI and the TV through HDMI. It makes no difference if the program is installed on HDD or on SSD. It just needs to use any kind of graphics acceleration and it only lags once.
