Question R7 240 BSOD - amdkmdag.sys VIDEO TDR ERROR

[Guilherme Varella]

R7240 Black/blue screen, can't solve
I got a r7 240 2gb GDDR5 in January, since the day i got it, i'm having a black screen issue, the sceen goes black but the sound keeps on, sometimes it crashes entirely and i always need to do a hard reboot. I've tried everything i saw in forums, Tdrdelay, old and new drivers, disabling onboard graphics, always using DDU, nothing can solve this, i tried yesterday formatting and installing windows 7 for a try, and it keeps happening, i never got a crash dump file in windows 10, in w7 i got one everytime:

On Sun 04/04/2021 12:44:34 your computer crashed or a problem was reported
crash dump file: C:\Windows\Minidump\040421-8642-01.dmp
This was probably caused by the following module: amdkmdag.sys (0xFFFFF8800F0C8850)
Bugcheck code: 0x116 (0xFFFFFA800BAC52E0, 0xFFFFF8800F0C8850, 0x0, 0x2)

someone could help me? should i try warranty already? 4 months and i can't solve this black/blue screen issue, the memory, MOBO and graphics card were bought in January and it all works perfectly without the GPU, running at onboard. If it can work for 16 hours it must not be some incompability, right?

The same system has runned a GT730 for almost 2 years, the PSU is working finely, so all the other parts...

Welcome to the forums, newcomer!

Version of BIOS for your motherboard? What is the make and model of your PSU and it's age? Is the installer for Windows 10, sourced using Windows Media Creation Tools? Does the R7 240 work in a donor system without the issues you've faced? Did you source your drivers from here?

Same problem when you connect monitor to the motherboard?

Why keep using W7? It isn't supported anymore.

BIOS was updated to the newest version at a technical assistance;

PSU is Thermaltake 430w 80+ white, i'm using it for almost 2 years, i was using a GT730 for almost a year and changed it for r7240;

Windows 10 i installed one time using bootable pen drive created with rufus, the second time was at the technical assistance, i believe using a windows CD;

i could not test myself in other system, they tested it in other system but no major differences, also, they tested a Nvidia GTX (can't remember the exact version, but i guess it was GTX 750) and it run normally without issues, even in benchmark/stress test;

Yes, all the drivers i tested were downloaded from AMD site, i'm currently tring the Recommended version 20.11.2.

It all works perfectly without the GPU, using onboard graphics.
I tried Windows 7 to see if something changes, well, at windows 10 i never got a crash dump file or blue screen, so i could not see where the problem was, at windows 7 at least i got a error code and dump file, but if i find a solution i will update to windows 10 again.
