Hi all, got a bit of a situation here.

So today I got a new PSU (500W Corsair) which works fine and everything runs as normal. The reason I got this was so I could put an R9 270X in my PC as I've previously (still am) stuck with intel integrated graphics. After a bit of a struggle the card and PSU both now power up.

However, despite being in the slot and the fans spinning on the graphics card if I plug in my monitor to it there is no display at all (but the system boots up as normal). But if I plug my monitor into the onboard graphics it works fine and the computer is completely normal.

Also, if I go into the display adapters thing via device manager there is only the Intel HD graphics. When I was looking at the quick install leaflet that came with the graphics card it says I should uninstall onboard graphics before installing the card but from other threads/posts this seems to result badly.

Should I uninstall/disable the on board graphics? I don't want to make my PC unuseable or anything and I'm a little scared to try this so o thought I'd ask here first about my whose situation.

Sorry this message is a little... Badly explained but I've been struggling with thus for hours now.

A few suggestions:

- reseat ur gpu in the pci express slot (make sure it's in all the way)
- make sure you connected a power cable to the gpu
- go into bios and see if theres an option to disable onboard graphics or enable your dedicated gpu
- if possible, try using the gpu in another pc

Yeah this is a brand new card; before I only had integrated/on board. Well, still do.

Just checking now for BIOS updates...

EDIT: Doesn't look like it.. It was a prebuilt PC so its a little confusing. I checked my system summary as it says "American Megatrends Inc. 0216, 10/04/2013"

So I guess that means its a little over a year old?

Cheers, just downloaded it but all the zip file contained was an image... opened it and it just said the model number and stuff. As far as I can tell nothing has changed from the BIOS. Should I try reinstall the GPU now or?

Yeah that's correct; sorry for being so vague. It is the CX500M.
