Hi all,

First time here, need to try and figure out what is wrong with my PC.

Few weeks back I started getting BSOD's randomly, always a different code and i could never figure out what was causing it. Prior to the BSOD, only sometimes, the applications might flicker, or if I'm playing a game they might reload the game window/freeze/crash it. Disconnecting me from the game.
I first checked all was secure in the PC, it was. Checked and made sure all drivers up to date, they were. I then went on to running Prime95, CPU seemed to be fine. Furmark, GPU handled it perfectly fine, memory diagnostics test...Hardware issue detected. Interesting I thought, so I took a stick of RAM out re-tested just the A channel, fine, moved that stick to B channel and tested and error. Done the same with the other stick of RAM, same message.

Must be fault RAM, bought new RAM, same issue.

Must be a faulty DIMM slot? Bought new MOBO, re-seated everything in computer, started working. Great, glad that was the issue. Fast forward to Wednesday this week, Game window flickers a couple times and then BSOD's. Boot back up, get in game, BSOD. Boot back up get in game, 15 minutes later error on game, BSOD. Here we go again.

Memory diagnostic test, Hardware Fault shows again. Now I've gone for a different new MOBO than the previous one, just to make sure it wasn't a batch issue. now I'm doubting whether it was the MOBO or not. Maybe there's not enough power, New PSU as old one is very old. No Change.

-Time to reinstall windows to see if it s a fresh install fix. Nope.
-Fresh install with no updates to drivers this time....nope.
-Fresh install to just the m.2 in case it's the SSD, nope.
-Fresh install to SSD in case it was m.2, nope.
-Maybe it's the GPU, switched out the NVidia GPU with an old AMD GPU, same issue.

On each one I've made sure the BIOS etc is up to date as well.

I've even gone as far as testing GPU, SSD and PSU in my ancient AMD FX AM4 rig just to make sure they were working fine, which they are, I'm on it right now typing this out. in the hopes that someone on here could help. I've called shops and computer people, they've all said, we wouldn't do anything different to what you've already done. so they can't give me a reason for me to waste my money bringing my pc to them to look at. I'm hoping someone on here might be able to help. I'm just out of idea's on what to do, the only component I haven't changed is the CPU. Would this cause the memory diagnostics software to bring up an error if it's faulty?
I'm at a loss otherwise, any help would be appreciated, apologies if this is in the wrong section, I couldn't see one that was right for this issue. but to me it seems hardware related - might not be though.

I think that's everything, it's been 2-3 days trying to get things to work and moved around and running with the kids about.

Specs of system are:
i7 7700k (never overclocked)
Asus Prime Z270-P Mobo (previously was Asus ROG Strix Z270e Gaming MOBO)
RTX 2070 black edition
Cooler Master Seidon 240v CPU Liquid Cooler
32gb DDR4 3000mhz Corsair Vengeance (Same just different sticks)
Crucial m.2 SSD 1TB
Cruicial 500gb SSD
1000w G3 80+ Modular Gold (Previously Corsair 650w Bronze)

Any feedback would be greatly appreciated. I can attempt to boot it up and run programs on it if people have suggestions for gathering errors, the Drives are now wiped completely though in my attempt to do a fresh install I done a full format hoping it would resolve the issue (this leads me to why I believe it to be hardware related)

Thank you for taking the time to read this and any helpful comments you can provide.

You have done just about all of the troubleshooting possible. The only suggestion I have is that there is a possibility that the memory controller [which is part of the processor on all modern systems] has a problem or has failed. This would explain why you keep getting memory errors even with different ram and a different motherboard. If you have another processor sitting around [even something like an i3] install that and see if you still have the problem.

Unfortunately, that is the only part I do not have a spare of and was the only part I didn't want to have to replace 😞 Thank you for confirmation I hadn't missed anything glaringly obvious and my diagnosis op the situation is potentially correct.

Question is, do I buy another processor and try it, or do I weigh out for a new processor, like a 9th or 10th gen and new mobo?

Any thoughts?

I know another i7 is around £200 used and £300-400 new still, whereas a 10th gen is £530ish I think and a 9th gen not much less.

If it were me, I would opt for a newer motherboard/processor however you do have a lot of intel boards sitting around now.
Since nothing has fixed the problem, you could try the following. Boot into the bios and up the cpu voltage slightly and repeat the memory test. Most asus boards use an offset either + or- and you would use the + Up it the minimum allowed and test. If you get no errors, you know the cpu is now working with more voltage. This is not a fix however it is something to attempt to find the problem.

Good luck. Off for a while

So I upped the voltage slightly and still got the error on the memory diagnostic, but when I enabled the XMP profile and re run the diagnostic, I didn't get any hardware error on the memory diagnostic.

Unsure if that means anything?

Well is it working now or not?
No, I thought it was, come to boot up and play something today as I haven't touched it since my last post and within 3-5 minutes of playing I get a error:

ERROR #132 (0x85100084) Fatal exception!

Followed by a bluescreen, which I believe was the 'attempted to write to readonly memory'

Any thoughts? I mean I've used the Hard Drive in another rig and had no issues and I've had the RAM replaced with brand new sticks as well as the new MOBO.

This was also an error using intel onboard graphics as I removed the GPU from the PC altogether to discount that indefinitely.

As I said, possibly a failing memory controller on the processor. That is about the only thing you have not tested or eliminated by replacing.
