So last week I bought a 5450 to install into my hp a6120n so that I could run three monitors for my business.

So it finally gets here and now I'm pulling my hair out tryin to get it to work. Here's my progression:

First, I followed the ati directions: unistalled existing drivers( intel on board graphics), powered down machine, took case off, installed card, put it back together, powered it on.

Results: power button lights up, fans spin but no boot.

Check card seating three times, everytime same result power button lights up, fans spin but no boot.

Take card out, machine boots perfectly. On board drivers reinstall just like it was before.

So I'm thinking now that it's probably my underpowered power supply. So I go get an overkill PSU from compusa, unistalled existing drivers( intel on board graphics), powered down machine, took case off, installed card, put it back together, powered it on. Same Results: power button lights up, fans spin but no boot.

So now I pull the card out and check the bios screen to see if I can set the primary video adapter to pci-e... There is no option in bios to enable PCI-E only onboard or pci. I go to ASus website to see if there's a bios update(board model number:p 5lp-le) they don't support it since it was made for HP. Go check HP website and there's only one newer bios update but I can't install it. I get an error saying "incorrect bios for your system(253)".

So what do I do next? I really don't want to buy a new motherboard... I feel like there should be a way to make this one work. Please help!

Definitely not a Power Supply issue. The card only uses 25 watts under load (laughably low power requirements). Source: http://guru3d.com/article/radeon-5450-review/6

EDIT: CT might have a point. Do PCI-E 2.1 cards have issues with PCI-E 1.0 slots?

Double Edit: Just ignore me, XD

that's what i figured. return it for a 2.0 card.

FYI, to get the 3rd monitor to run you will an active display port and they go for around $100 on newegg. ATI tends not to tell you that.

The board slot is PCI- express x16, so I guess that makes it 1.0. Would that be the issue?

yes but its a hit or miss since some BIOS updates let 2.1 run on 1.o slots and some don't.

Dang, I bought the ATI approved display port to VGA adapter already. Any thoughts on a workaround?


If not, any card suggestions that will allow me three monitors?
