Replacing faulty grfx card with same model freezes/locks up machine
Hi,
My Dell Vostro 430 (Win7 x64) has an nVidia G310 card but the fan is faulty (very noisy - sounds like a small chainsaw). I had a replacement part (same nVidia G310) sent to me by Dell.
However, when I install the new the grfx card into the machine, Win 7 starts to boot, gets to the splash screen (just before you can select the user) and then locks up/freezes.
Reinstalling the old card back in the machine, Win 7 will boot successfully.
Dell tell me that the card they sent me is the same model as the one in my machine. Does anyone know what could be the cause of this freeze/crash/lock up?
If they cards are exactly the same, then the same device drivers would you expect this problem with the card?
Any suggestions on how to diagnose?
I know the replacement card works (kinda) as I can boot the self installed Linux system on this Dell computer and graphics display is fine - machine just locks up when booting Win 7 so I suspect drivers or something similar.
Any help appreciated.
thanks
