Have you run any stability tests on the CPU and memory? I would try lowering the CPU clock speed and the memory speed, just to rule out either of those as the cause of the issue.
I would then recommend a system clean up and a fresh installation of 16.7.3, to see if it resolves the issue.
1. Run the Windows self check tool to check scan and automatically repair any corrupt files found in Windows. There is a guide on how to do it here. What you need to do is run an elevated command prompt (elevated means run it as administrator) and type SFC /SCANNOW. This will generate a statement indicating if errors were found the Operating system and if they were fixable.
3. Update Windows. Install all available critical, recommended and optional updates. Often Netframework and Visual C are included in the recommended or optional updates Windows provides. Windows should always be fully up to date before installing our drivers!
4. Use DDU to sweep the system of AMD drivers in safe mode.
5. Install the latest Crimson 16.7.3 drivers once the above is completed and check to see if the issue is resolved.
First I would like to thank you for your quick response. I have ran the
Intel CPU Diagnostics utility and my CPU passed. I have also ran several
memory tests with memtest86+ all of which were clean. I even ran the mem
test directly after a restart/failure and it came out clean. I have tried
two different PSU's. I might try my separate PSU again just in case, (Its a
750 watt). I have tried a new motherboard (returned asrock mobo and
purchased MSI). I have tried one stick of ram at a time. I installed my
spare nVidia card last night and it has been running fine so far.
The first time it crashed on the (NEW MSI BOARD that i replaced in order to
try and fix the problem) i did notice that the radeon drivers would not
successfully uninstall. Through several restarts and uninstalls/reinstalls,
I was finally able to uninstall the drivers and ran the AMD CLEAN UNINSTALL
utility. I then reinstalled the drivers with errors. Control center would
not start. So i repeated the uninstall process with the AMD clean
uninstaller and was able to get the drivers reinstalled and working. I will
try this DDU utility next. I ran the SFC Scanow and it said it found and
fixed corrupted files. What does this mean?
It means there were some corrupted files found on your system.
Hey I'm going to do you one better. I am going to run the ddu cleaner and
then after i will uninstall My current PSU(850w thermaltake bronze cert)
has one 12v rail, delivering 840w. I will install that spare PSU i was
talking about (750 zephyr) which has 720W of power on 4 separate rails. I
will use separate rails to power each card. Wish me luck. And by the way i
have already done this on the old ASROCK motherboard with no success.
Same issue here :
Problem: Computer randomly restarts. No BSOD. A very generic error is supplied. Kernel 41. Loss of power, unexpected shutdown.
I precise that i acquired the card (RX480 Nitro + OC) 3 days ago and the problems start from here.
2 years now i had a 780TI and i never had a single problem with my PC. So the problem come from the RX480 for sure, hopefully software and not Hardware.
By the way, of course i have the same others problem than the other like blackscreens and 100% GPU Usage at IDLE.
Please fix thaht, id'ont want to regret to have bought a AMD card.
Ok buddy I feel your pain. The Black Screen Of Death I was experiencing was due to a power supply issue. Now i am not sure what out of two issues it could be.
1- Power supply faulty not supplying even power and causing cards to lose power and restart PC
2- Power supply is too good and has a security feature that shuts the PSU off if something overdraws the PSU (which the RX480's are doing, read about the power issue fixed in one of the early drivers) They shifted the power overdraw from the PCI slot to the PSU.
Overview- I say this because the problem PSU runs my Nvidia GTX 660ti OC with no problems whatsoever. It's a thermaltake 850PSU bronze. The PSU that works is my backup zephyre 750 that i pulled out of an old PC case that was laying around work.
As for the BLACK SCREEN problem. This is still evident. For example whenever i get home from work after using teamviewer to remote into work, my PC monitor will awake from sleep but screen will stay black. Also when watching videos on youtube or internet browsers my screen will sometimes go black.
This is different than the power loss i was experiencing. The screen goes black but i can still activate the capslock light which means the PC is still running in the background and am forced to windows key+r and manually type CMD then shutdown -r in order to avoid hard cutting power.
I assume the random black screens are due to driver issues.
On a second note. I dont know if you play overwatch but if so please let me know if you are experiencing video stuttering lag. For example at the start of a game all the sudden the video is freezing for sometimes 20 seconds and then starts moving again. I'm wondering if i should revert to an older driver because this is a new problem.
sorry for spelling. Wrote this fast.
RMA'd my cards. Everything works fine now.
Hey everyone. Heads up! My kernel 41 power error has resurfaced after a month of working fine. I went straight out and bought a 3rd PSU in case the first two were bad and also got a new surge protector + UPS. No luck. Computer BSOD with no screen and auto restarted about 10 minutes in. I replaced the CPU and Ram, took the psu and UPS back to best buy as they did not fix the problem. I am 100% after 3 psu's that's not my problem. I have replaced everything in my pc except the graphics cards and hard drives. My main in an SSD. My PC has not restarted with the new CPU and ram installed "yet". But lets give it some time as the problem has a mind of it's own and appears/disappears at random. Overwatch has been unplayable for the past two driver updates. Consistant 30 second freezing in the menue screens and booted from matches due to inactivity before the screen even moves. Complete FPS drop/freeze for 30 seconds - 1 min at a time with the pc running fine in background. PULLING MY HAIR OUT!!!!!!
I've had the same kernel 41 error, and constant crashes without bsod, with my new rx480 in a new computer. I think it's clear from all the threads that this is a driver issue, unless AMD is producing so many faulty hardware units (which I doubt). You may want to try the latest driver, as that's what was just recommended to me. I haven't yet tried it, but you can follow my thread - Frequent random reboots when display driver is enabled
I feel like there should be a sticky for this and an acknowledgment from AMD that there's an issue with the driver.
Hopefully the new driver will resolve it (but I don't have a lot of hope).
Hey buddy i replied to your post. Gave you everything i have went through..
It's pretty extensive. Excited to see how bad 16.9.2 is.........
