Based on your description the issue is either with your display(s) + cables, or your motherboard, unless in the unlikely event you ended up with 2 damaged GPUs.
I'm not sure what steps you've taken to troubleshoot the issue and you didn't indicate whether or not this happens on both displays you have listed. If it happens on both, you might want to verify that the card(s) are seated properly in the motherboard and all PSU cables are hooked up.
Have you tested the displays on your old computer (with the same cables if possible)? I would do so to rule out the displays; if they are working (with the same cables), it'll most likely be an issue with your new system.
Sorry i wasn't real clear. I have tested the displays, they work fine.
I've reseated the cards. On the rx580 i made sure the power cables (4 pin + 2 pin) were connected properly. The x1650 doesnt have any power connectors, guessing it gets it's power through the pcie?
I have an old Dell in the garage but i think its got an agp board. I could probably find someone to let me pop the x1650 in their pc to test it.
If it works in a different pc then the problem is likely my mobo or psu? Is it possible there is a cable loose somewhere?
Is there any tests i can perform on the mobo?
Should i pull my multimeter out and test the psu?
I don't want to send you on a wild goose chase; eliminate the problem pieces on your system, systematically. If that old ATI card works on another newer system you might want to test the PSU and the motherboard if it has any access points like the Asus Crosshair motherboard do.
After the BIOS update, did you try to run the BIOS on default settings? ie no changes to OC's or other power settings? I don't think it's a bus interface compatibility issue (PCI-e 1 vs PCI-e 3) as it should(TM) be backwards compatible, besides you already had this issue with your RX 580. It could be bad power phases/regulators on the mobo or something as simple as a BIOS misconfiguration. Either way, I would probably contact your system's manufacturer or whoever built the system for service/warranty options at this point.
I updated the bios to 2.40 then 2.50 last night.
I made no changes to bios so its still at default settings i.e. voltages set to auto.
Im not sure what test points are, cant find any info on it for my board. Im going to try testing the gpu on a different system later when i have time.
I really appreciate your help. Im going to open up the wire compartment and make sure everything's connected properly (again). If i still have problems when my new RX 580 gets here I'll probably have to just send the whole system back. Spent too much money to get a defective pc. At least i have a 3 year warranty..
This is uncanny, and it can't be coincidence. I am having the same problem. Like, the lines I see look exactly the same. I bought a system off eBay with the following specs:
ASRock AB350 Pro4 AM4 ATX mobo
AMD Ryzen 5 1500x 3.5GHz
MSI Radeon RX 580 8GB OC edition
16GB (2×8GB) GSKILL DDR4-3000 Trident Z
ATNG 600W 80 plus PSU
WD Blue 1TB HDD 7200RPM
Corsair H60 liquid cooling system
Windows 10 Home Edition
Acer x193w / AOC G2460pf 1920x1080 144Hz monitor with Freesync.
When it arrived, I hooked it up to my monitor, an Acer x193w that maxes out at 1440x900 on DVI. I noticed the lines right away, but I figured it was probably a combination of the outdated monitor and the graphics drivers not being installed. At the time I was more concerned about how Windows was not properly installed on the system as advertised and having to go through the hassle of fixing that. I packed up the thing, wrapped it, and put it under the tree as my Christmas present from myself (and my wife). Meanwhile, I went and picked up a new monitor (AOC G2460pf) knowing I would need it to use my new GPU to its full potential.
So Christmas day comes and I finally hook up my new desktop to my new monitor (which has been working fine with my old PC) for the first time. To my suprise, I get absolutely no signal using DisplayPort or HDMI cables between the RX 580 and the new AOC monitor. I finally tried DVI, and that worked, but with very similar funky lines as had shown up on the old Acer monitor. "No big deal," I thought, "I'll just install the graphics drivers and that will solve everything."
Needless to say, it didn't. In the middle of the driver install, the screen goes black. Not only that, but the system froze. "How do you know without a working display?" you ask? Because it doesn't shut down without pressing and holding the power button. I could get DVI signal in BIOS, still with funky lines, but lost any video signal after Windows startup. No DisplayPort, no HDMI, no nothing. I had to do a Windows 10 reset just to undo the failed install of the graphics driver, because, as you know, Ryzen 5 does not support onboard graphics.
Everything you described, I'm also experiencing, the Microsoft basic display adapter thing included. I haven't picked up a different GPU to test yet, but I get the impression it would produce similar results.
I have no convenient way to test the RX 580 apart from my new PC, as it's not compatible with the PCI-E 2.0 slot on my old PC. Reading this post gives me the impression it's not simply a faulty GPU, though. I updated the mobo bios to the latest version (3.30), but that had no effect. I confirmed it is a UEFI bios and not the legacy mode bios the RX 580 is incompatible with. I may try fiddling with the CMOS or the power cables next, but otherwise I'm at a loss for what to try. I really want to figure out a way to get a working display off the RX 580 before I port over my SSD from my old PC.
Besides the fact we're both using a combination of RX580, Ryzen 5, and ASRock mobo, what's the common denominator?
To follow up, I tried fiddling around with the power cables with no effect, and eventually gave up and sent the RX 580 in to MSI for an RMA. I got a new RX 580 card in the mail earlier this week, and it's working perfectly. I guess it was indeed just a bad card.
