Question Please help me with GPU error

[Jeromekrimmer]

I just built a PC with a

650w psu,
i5 2400 optiplex 990 motherboard
some full tower case (idk what one)
pcie riser cable and an
RX 570 8 gb phantom oc

When I first set up the gpu and installed drivers it worked fine and came up in pcie x and device manager. I reset my PC and plugged my monitor into my gpu and it booted fine and it said it was ok in device manager. But when I launched a game my PC crashed. I turned it on again it said there was an error with the gpu in device manager and windows had disabled it.

I reset my PC and I haven't had any signal from my gpu since, if I plug my monitor directly into my motherboard output and launch it says that there is a gpu detected and I need to plug my monitor directly into my gpu and then restarts but when I plug into my gpu it still turn on and I get fans and the lights on my keyboard work but I don't get a signal.

Can someone please help me resolve this?

Connect card directly (without pcie raiser cable) and try again.
If still no luck, then try a different graphics card.

might be a PCIe riser problem

which power supply are you using? brand and exact model please

all power connectors plugged into motherboard and GPU?

Update:
I got it to launch with the gpu connected and with the monitor connected to the motherboard output and it says the gpu is working but I still get no output though the actual gpu and I can't actually use it without the output going through the actual gpu

cant connect without the riser because the gpu is too big and won't fit over the 24 pin connector

I also don't have another graphics card as I blew all my money on this one

get a different PCIe riser, maybe this one is faulty

Ime pretty sure the risers fine because the gpu comes up in the Radeon adreneline and stuff now but I still don't get an output its probably the gpu outputs or something

reset the BIOS by jumper

still could be the riser
