Hello,
today i recieved my gtx 650
and i started it, worked fine until i installed driver and restarted it then on login it crashed restarted again again this way.
i started safe mode it worked fine there. and uninstalled driver worked fine but driver install it crashes at login

i have c2d e7400 2.80 ghz, 2 gb ram ddr2 and odyssey 450w.
i checked odyssey sticker and it is 12v on 10a
now i wanted at least 400w psu with 12v on 20a under 1000 rs.
i saw zebraonics and vip was very low on price.
which would be able to run my card or any other cheap good psu




edit: is this really psu problem or driver problem
