hey, I have an Acer Aspire TC 105 EB 11 desktop. It has on board video which is integrated radeon hd 8670d solution.
I just bought a diamond radeon hd 7770 graphics card with 1GB GDDR5.
I just want to know if this card is compatible with my Acer desktop.
By the way, I seperately intsalled a 600w power supply with 2 PCI express power connectors. So that should not be a problem.

The thing is I already tried installing the Diamond Radeon hd 7770 and my motherboard didn't recognise the new hardware. I tried everything I could, turning safe boot mode off, disable on board video, etc. I'm thinking of replacing this GPU with a new one which is Sapphire radeon R7 250. See this link,

can you tell me a solution to my Radeon hd 7770 not working and can you check if the new GPU is compatible with Acer?
Would really appreciate it!

Any GPU should be compatible with your computer as long as the motherboard supports the 16X PCI slot. You shouldn't get the R7 250 either, it's basically a re-branded step down from the 7770.

You may have to go into your settings and uninstall the drviers for your integrated graphics, and install the 7770 and install AMD's drivers.

I think I may have to go into BIOS and go to init graphics, and choose PCI internal.
I may also have to disable safe boot mode off.
Do you think that will work?
