zach   234 #2 Posted September 23, 2018 Things just break. I wish I'd got a quid for every time I've heard "It was ok yesterday"  What I would do is double check the BIOS to make sure your 7770 is set to primary. Also look in device manager to see if it's there, and the drivers are working.  It could be settings/drivers/power. Or it might have just packed in.

Ghozer   112 #3 Posted September 23, 2018 Since you can use the onboard, I would suggest using that to boot up, then use Driver Sweeper, ( https://www.guru3d.com/content-page/guru3d-driver-sweeper.html ) to remove all AMD Radeon Drivers, and also download then install the latest and see if that helps...  Otherwise, the card may be faulty... but it may also be recoverable, depending on the issue..  there is also a small chance it could be your power supply, if it's not supplying enough voltage to the card, or the PCIe power cable could be damaged/faulty etc...

Â That is going to be a collosal waste of time, being as you can't even get to BIOS with the card installed. Â What happens if you stick the card in, but connect to the onboard graphics for the monitor output? Â ---------- Post added 23-09-2018 at 22:15 ---------- Â If you can get to BIOS with the card installed, but monitor connected to the onboard, have a gander around to see if the default card options have somehow been toggled. May also be worth clearing the CMOS and trying again. Share this post Link to post Share on other sites Share this content via...

May also be worth clearing the CMOS and trying again.  May be, but it's eliminating things..  I have known it before NOT work in BIOS, but work fine in windows (had to be plugged into onboard to use BIOS) - this is an easy fix/change, but have to check if the card is working at all first... hence the suggestion!

Guest   #7 Posted September 24, 2018 Also it's regarded as Legacy by AMD now, so make sure you download Legacy drivers if theyre available. Share this post Link to post Share on other sites Share this content via...

Climbing   10 #11 Posted September 26, 2018 So I had this exact problem last week. Only solved by replacing the motherboard. Despite flashing the BIOS and everything else under the sun.  Just one of those things I suppose Share this post Link to post Share on other sites Share this content via...
