phoenix miner won't start after installing nvidia nforce drivers

[micc]

Accidentally removed nvidia important drivers because i switched to ATI Radeon HD 5770. After re-installed nvidia nforce drivers my phoenix miner won't start at all, it just appear for a second then poof disappeared, it was working before the re-installation. Can anyone diagnose the problem here? thanks alot.

my phoenix commands are C:\Users\Gateway\Desktop\phoenix-1.6.2\phoenix.exe -u http://xxx:xxx@btcguild.com:8332/ -K PHATK VECTORS BFI_INT AGGRESSION=12 WORKSIZE=256 DEVICE=0  FASTLOOP=FALSE

ps: the phoenix error was something like this

One possibly silly question:
Why have you reinstalled NVidia drivers?
I have a motherboard with a built-in NVidia, and as soon I have inserted my 5770, it stopped working.
I'd love to have it back as main adapter so I could use it for my ubuntu desktop, freeing my ATI exclusively for mining.

You must install pyOpenCL
