Desktop not fluid after kernel3.3.8/nvidia295.71 update

Hi,
I just updated my PC (Mageia 2, ASUS P5VD2-VM Motherboard, Intel Core2 6600@2.4GHz, 3GB RAM, Nvidia GeForce 7300 GS) with the latest updates [kernel (3.3.8) and Nvidia drivers (295.71), besides gimp and ls-detect] and now the grahics are not fluid, everything in the desktop (moving windows, effects, typing...) seems to "halt" every few seconds (very noticeable in 'glxgears' also). And it also happens playing videos (with two different players), music (with amarok),... Nothing is fluid. It did not happen with the previous kernel. Anyone else is affected?
I also updated my laptop (Dell Latitude E6400, Core2 Duo T9400@2.53Hz, 4GB RAM, Intel Graphics) and this does not happen, everything is fine.
I was stupid enough to uninstall the previous kernel (and nvidia drivers), so could you help me solving this issue, or reverting to the previous kernel?
Thanks a lot
Pablo
