Hi guys,
Got the following rig set up:
I recently purchased an Asus R9 280 DirectCU II graphics card to replace my old Asus GeForce GTX 550Ti.
However, upon installing the R9 280 and turning on my PC it appeared to POST and then boot - i.e. the sounds coming from the PC, the HDD activity, etc were consistent to how it sounds when it POSTs and boots normally - but there was no signal coming from the graphics card at all throughout. Blank screen during POST, boot, etc.
The monitor is connected via HDMI. Checked and ensured that both PCI-E power connectors were connected properly and that the LEDs on the graphics card itself were showing green rather than red.
What complicates things is that no matter how hard I try I can't find any threads online mentioning my motherboard. There are plenty of people with M5A78L-M/USB3 motherboards but none who have a M5A78L/USB3. I find the suggestion that the R9 280 could be incompatible with the M5A78L/USB3 doubtful as it shares the same chipset as the M5A78L-M/USB3?
I will be clearing the BIOS tonight and also putting the old graphics card back in to try and see if there is any settings in the BIOS I can change in order to make this work but does anybody here have any ideas what could be wrong?
Thank you all very much in advance!
