Is the BIOS set to the right display output? Sometimes you have to manually switch it to the PCI-e slot for video out.

I see lots of this here with prebuilts.. first you notice that theres upgrade info for the cpu and memory but not for the vid card ???

some models of store bought computers [dell.hp,acer,ect..] may come with a ''locked or fixed'' bios and may not allow you to change certain hardware as a video card.. this is done to protect them from undue warranty claims and refunds .this is not done to hurt you but to protect them. you really need to see if that upgrade has been proven to work in your model first before you invest money in it .. there are a lot of these threads here at toms to look at some models will allow upgrades and some dont.. and a lot of guys here say ya ya ya when is really no no no...it would be sad you spent $200 on a card that wount post after you installed it as most find out. then get told its your psu and you spend more and end up right back where you are now, but its up to you good luck..


you got to know the the boards in these computers are not like the ones we use to do custom builds witch are open to upgrading with in the boards compatibly . the bios is custom made for there design and just for the parts they authorize to be used on there computers there only guaranteed to work as is out of the box as you bought it ,..


just something for you to ponder on this and I do hope you get it worked out

How i can get to BIOS if i cant see anything through my screen. Its just black and says no signal detected

 

[ThomasJ93]

By hookin the screen up to the onboard card. I saw at least a DVI port on the motherboard.

[lauri_forsman]

as I stated above that's between you and hp and there proprietary bios that may not support certain aftermarket cards if any at all
