Any ideas or tips?
My thoughts:
* could be dodgy power supply - the card that came with it is not externally powered. The new card is.
Hmm…I'm always reluctant to blame hardware until the software angles are chased down, and the last change was deleting software. Presumably fans are spinning and lights are on showing power or AlphaBravo would have said that everything was dead.
If the motherboard graphics port shows nothing at all on boot (no POST, or hit a key for BIOS) then I guess a dud power supply is likely, these things will show before any software loads.
If it is only when launching Windows that the display blanks, then reboot in safe mode and choose generic display drivers as a starting point.
+1 on the power supply. Would be the first thing to check.
Randomly I upgraded my PC to a 960 a few years back and when I installed it my PC booted and then shut down. Thought it was a dodgey power supply so replaced that however it ended up being my motherboard. Not sure what killed it because I still have the card and its fine. I had a no-name sort of power supply so I'm still guessing that killed everything.
Do you know what the old card is that is working with it? For the record the RX580 Max TDP is 185W higher than similar ranged GeForce cards that are around the 120 mark.
Thanks - well apparently part of the issue is the fact I must have knocked the ram. I am back to square 1 - the graphics card that came with the PC is working, but the Radeon card still doesn't.
For the record - the Power to the graphic card is via an adapter - 2x 6 pin outlets leading to a 1 x8 pin connector to the graphics card.
Look at each point of potential failure, why would it be the psu ? Especially when it still works with the old video card. The only issue could be is that the psu doesnt provide enough power, for the new video card. Especially since older systems cpu/mobo are much more power hungry than todays lower nm offerings. So overall power usage will be much higher overall.
Second is the cabling from the power supply to the video card, these rarely fail, but its not like it never happens, try different cables.
The 3rd thing is software, did you uninstall the old drivers, clean the system of any possible remnants of the old drivers, then reinstall the correct new drivers ?
The 4th thing is bios, make sure its being detected in bios, if not then you have a hardware fault.
If you are getting no signal at all, you can also check the cable from the video card to your monitor, just cause it works with your old video card, doesnt mean it will work with the new one, whenever i get a new video card i usually get the latest cable as well.
What outputs did your old card have? According to specs the Radeon has HDMI and DisplayPort. Maybe the screen is on the other output? Is there some setting on the BIOS to select the primary output?
Is the Radeon in the same slot as the old card? If not do you know that the slot is good? Is there some setting the BIOS to enable the slot?
For that matter what kind of PC and monitor have you got?
Could be:
….best bet is to take apart everything, and put parts in one-by-one and diagnose what is functioning.
Then try to update everything (BIOS, gBIOS, Windows 10 clean install etc etc).
Now everything should be working, or you will have a better idea of why it isn't.
If its working congrats, if not working, take it to a PC Shop.
(While you're at it, check if any of the parts still has a valid warranty. I remember some guy that got a good deal on two Core i7-4790K's off CraigsList, but he was scammed as they both ended up being burnt/non-functional. Lucky enough the guy noticed both chips were covered under warranty so Intel replaced them for Brand New ones for free, so he ended up getting a phenomenal deal at the time.)
It's an i7. The graphics card that came with it and the new graphics card are both in the same slot, but the card that came with it doesn't use any external power. The compuer itself now runs perfectly with the old card, but won't boot up with the new card - or at least i think it won't boot because there is no output - not even the BIOS screen. Both cards have been tested using VGA and HDMI output. VGA to a nold monitor and HDMI to a new monitor and the TV. Same result for all of them. The 2x6pin -> 8pin power adaptor works in the other PC.
then the new card is faulty.
Unless the mobo has onboard video, the fact that the BIOS didn't beep with the Radeon suggests that it's detected but doesn't generate video. You say the Radeon has worked with another mobo, so I think that leaves its power supply in doubt.
What's the wattage of the PSU?
Is it a proprietary PC like a HP or Dell?
Have you tried to ensure that the new card is inserted into the PCIE slot firmly?
Swap slots if have another?
Cheers
Nah not psu. High watts mode won't be turned on then. What do the fans do on GPU do? Spin fast and then slow ? Are the hd'd lights working?
Does the 2nd hand PC have built in graphics? Assuming it's an Intel system it should. Try connecting the monitor to the built in HDMI outputs.
a very likely scenario
Age of the motherboard's BIOS has not much to do with GPU compatibility. What is more likely the PSU was on the verge of failling, and putting your power-hungry RX580 graphics card into the system probably caused the old PSU to kick the bucket.
