Graphic card problem?

Question

hi there, i recently installed nvidia geforce 8400gs on my desktop. my desktop has core2duo 2.2 ghz processor, 1 gb ram and has on board video card of128 mb memory. before i installed the graphic card my 3d modelling software ran smoothle unless the drawing file became too big. but after i hav installed the graphic card even the small files also feel terribly sluggish on my system.

reason i brought the graphic card was to improve real time on screen graphics display. but the installation has just resulted in the opppsite. my mother baord is asus x series. p5gc-mx . please help!!

i use google's sketchup for my 3d modelling needs which used to run fine on on bboard graphic capability till i installed this card. pls help. thanks

Answer 1

Hopefully u entered the bios and Disabled the onboard graphics.

and ure new card has the latest drivers.

also u may want to go to Nvidia's website and see what the min specs for the psu are for that card.

if it says that card needs 22amps and ure psu's +12v rail is only kicking out 18 then its low on power that it wants

Answer 2

I guess you uninstalled the drivers for your old graphics before you installed your 8400 and then installed the new cards drivers after you booted back up, right?
