Can't uninstall marvell 61xx driver

Hello,

I was updating my Asus P5Q-E and installed the marvell 61xx raid driver (Marvell 6121 SATA Driver V1.2.0.69 for 32/64bit Windows7) , since I have 2 hds in raid 0 (supported by two orange sata in the motherboard).
But now my system boot time is terrible slow and I can't uninstall Marvel 61xx driver in Programs and Features since the uninstaller says "Can't uninstall driver because OS volume is handled by 61xx driver".

Everything was running ok before I installed this driver. Tried Revo but it didn't work as well.


Please help!!
