Graphics Card not recognized / only 1 resolution available

by HelloImBob / May 27, 2013 5:48 AM PDT

Hi, I have some weird problems with my display.
The weirdest part is where it worked fine for years and suddenly it doesn't work at all.
My HDD just failed, so I had to get a new one and installed Windows XP, SP3 on it.
Suddenly nothing seems to work anymore.
Everything besides the HDD is the same, yet my graphics card is no longer recognized properly.
It is an Nvidia GeForce 9400 GT (100% sure), but for whatever reason the
driver installs it and Windows recognizes it as an Nvidia GeForce 6150
SE (briefly Windows tried to auto-install it as 9400 but failed).
I tried everything, installing from my original driver disc, installing
the Nvidia automatic driver detector, downloading and installing the
9400 GT driver directly.
Still, All I can ever get is the 6150 SE.

And another, possibly related thing is that I only have 800 x 480 or 1024 x 600 or some other very low resolution available.
Windows display shows all those fancy settings but setting it to
1600x900 or 1920x1080 or anything else does nothing whatsoever, the
resolution stays absurdly low.
I tried re-installing my monitor driver, but it's already installed and I
cannot get a new version because apparently Samsung discontinued
support for it (S24A300BL).

I'd REALLY appreciate some help because this is really weird and confusing and causes me quite some problems.

The 6150 SE is integrated on the motherboard, most likely. So that's present. But something is wrong with the 9400 GT. I'd check if it's still powered and correctly in the slot. And I'd check if maybe there is a BIOS setting like "only use integrated graphics".
If all looks fine and still isn't, I'd try another video card.

Indeed, that little switch in the BIOS, no idea how it got set to only use integrated graphics, but now I just installed my graphics card driver again and everything works perfectly!
