PC experiences various BSODs?
PC experiences various BSODs?
The dumps for the older (250GB) system also look very much like RAM issues. There are no third-party drivers involved in any of these BSODs either. Three of these dumps fail when the kernel is allocating memory (RAM). The fourth fails in the amdkmdag.sys driver (the AMD graphics driver). Although the version of this driver is getting old (it's dated March 2023) I rather suspect that this may be down to a RAM issue too.
However, the AMD Crash Defender driver amdfendr.sys is also involved in this amdkmdag.sys BSOD (unsurprisingly). I have seen a couple of other users with BSODs that seemed to have been caused by the AMD Crash Defender service, uninstalling it stopped the BSODs. This service is essentially an AMD version of the Windows TDR feature so you can do without it, at least as a test - assuming it's installed on your current system as well. There is no evidence in the other dumps that amdfendr.sys is involved but you never know.
That you are having these BSODs on two different systems installed on two different drives means one of two things....
There is a hardware problem on the PC
You have reinstalled the problem (a bad driver) on both systems
Is it stable when you
start Windows in Safe Mode
?
In Safe Mode a stripped-down Windows system is loaded, with only critical services and drivers loaded. Typically no third-party drivers are loaded. This does mean that you won't be able to do any useful work in Safe Mode, or play games, and many of your devices may not work properly (or at all) because their drivers have not been loaded. Your display will be low resolution for example, because you'll be using only the Windows basic display driver.
The usefulness of Safe Mode is that because it's a stripped-down system consisting only of Microsoft services and drivers it's very stable, so if you get BSODs or crashes in Safe Mode you almost certainly have a hardware problem. On the other hand, if it's stable in Safe Mode then your problem is with a third-party driver or service that wasn't loaded in Safe Mode.
I haven't tried booting Windows in safe mode yet, I'll check it out sometime later. And the single stick thing seems no bueno as well, I wasn't in the room to witness the BSOD personally but the PC did restart with a crash log this morning. I'll wait a bit more then swap to the other stick, but this is also not looking like the problem.
As for the AMD Crash Defender thing, I haven't noticed anything like that even installed on either of the systems but I'll look into that as well later.
.............But here's something else. Can you check out
this thread
that I stumbled upon? The resemblance to my issue from the 2 most commonly occurring BSODs to the exact same
CPU AND RAM combination
the user has is way too close for comfort (
this is mine
). The user claims they eventually swapped PSUs but the issue was persisting, just more rarely (so is mine right now but I haven't swapped anything yet). HOWEVER, another user in the thread claims they had the same issue but fixed it by manually overvolting their CPU settings. I don't see their specs, but the OP is almost exactly the same as me, and with a different MB, which also makes me believe my problem isn't the MB either. It looks like it might be some CPU + RAM combination that might be conflicting? Which is weird that it lasted for a year without BSODs, although I did have that occasional freezing issue since almost the start... I won't do any tests on this yet, since frankly I'm scared of doing any sort of OC on PC, but it's definitely something to keep in mind for later, do you think?
