Just got this graphics card NVIDIA geforce 8400 gs 512mb ddr3

1) 8400 is a fossil, and was underpowered and crappy even when it was new
2) 8400 needs power through the ATX power connector; if you're using a 20-pin instead of a 24-pin, it won't get enough power.
3) many 8400s were low-profile, with the VGA port connected to the card by a ribbon cable. This meant you could use a single full-height bracket, or a double low-profile bracket. If you've got a half-height card, make sure the VGA port is properly plugged into it.

In general, a working video card should get you to the BIOS setup screen, regardless of any driver or OS you have. If it can't do that, it might be broken.

Thank you for the reply
1, I'm a poorfag
2, No idea the difference between the two
3 I did have to remove the steel peice to fit it in, and the cable is properly connected
The pc will load up properly, I can here the "dun dun! dundundun" thing it does on startup, just no display no matter what I do

>2, No idea the difference between the two
One has 24 pins and one has 20 pins.

However, Google tells me your computer has neither, because Compaq put their own weird power supply in it.

Thats why I was confused by that then...
So what does that mean exactly?
That I can't use this card?

>>250151
Where did you get it from anyway?
Did it ever work?

Haven't seen it working myself though
