Yeah, I did two rounds of memtest and there were no errors. Honestly, I'm kinda giving up at this point. I don't know how to fix computers well because I lack the skills to find the problem. I just feel like throwing away all my parts and saying goodbye to PCs makes sense. There are too many things that cause trouble and I can't figure them out without testing everything one by one. Even if it's hardware or software, I don't know which part is broken. It's all BS and after spending almost £1400, I should have no more responsibility for this mess.
It's definitely hardware because you already guessed wrong about software by doing that: Now, you've also taken out RAM as the possible problem. So here is what I think based on the info we have: * your CPU is getting way too hot * your power supply unit (PSU) is failing. As i said before, random restarts or shutdowns are usually caused by either high heat from the CPU or a bad PSU because of that. Did you turn up your CPU cooler and case fans to their fullest, just to see if the CPU stops hitting those scary 95C numbers in Cinebench? Or you could try getting a brand new, solid quality power supply, which would rule out any PSU problem straight away. Even if the issue stays after that, at least you upgraded your power source from it. Running a computer badly and ignoring it can cause all sorts of troubles too. And picking bad parts like a poor PSU makes things worse. When it comes to price, i'm pretty neutral about it here. For example, my main PC build (Skylake) cost me €4705.67 total or £4013.47 back then. It has been running smoothly for the past 9 years now, since i take great care of every single one of them PCs in that matter. Think about it this way: if you build a house and cheap out on the foundation, then no matter how fancy the villa or castle you build on top and how much it costs, once the ground starts giving way and everything sinks or tilts, nothing matters. It's the same thing with PCs; when the power supply is weak, it doesn't matter if your whole build cost €/$/£ 500 or €/$/£ 5000. No PC should ever crash because of a bad power supply.
Do you need advice on picking a new power supply unit? It needs to be fully modular and fit within 140mm or less in length. I suppose I'll aim for a 1000-watt model if I'm ready to spend the cash and want to keep things future-proof.
A 1kW unit that fits under 140mm? That's quite a stretch unless you use an SFX PSU instead of ATX. Here are two ATX PSUs I know with that size: Seasonic Focus GX-1000 ATX 3.1 (link provided) and Super Flower Leadex V Pro Gold (link provided). They have very slim specs. There aren't many other options, though some might be out of stock or lack reviews like the Thermaltake unit I saw or the Super Flower Zillion FG series. Both Seasonic and Super Flower are good choices for me personally. One stands out because it's ATX 3.x, while the other is ATX 2.x. If you want more variety, just drop your requirements down on length or power capacity instead.
Honestly, I was almost ready to buy another power supply unit, but my current one gets marked as B+ anyway and even tells me that the performance is good overall. So why are you asking here about potential problems when your own source says it's totally fine for a mid-range PC?
Which list? I linked two reviews and there's no PSU tier list in either of those. TH review conclusion says this: Last i checked, "decent" and "good" mean completely different things. 🙄 To me, "decent" means mediocre, rather than good. And while mediocre quality PSU would suffice for office PC, without dedicated GPU, it wouldn't be enough for any build with dedicated GPU. For dedicated GPU builds, minimum would be good quality PSU, while great quality PSU is preferred (mostly due to high power consumption the PSU sees due to the dedicated GPU). But if you consider that the build, for the most of the times, works fine and PSU powers everything without issues (except the few random shut downs/reboots) - sure, you could call your PSU to be "overall good". Calling PC "midrange" is way too vague. I'd classify your rig, overall, high-end. Sure, CPU is mid-range option regarding Ryzen 7000-series, but GPU is top-end, since it can comfortably push 60+ FPS on 4K. If GPU would be able to push 60+ FPS on 2K but not 4K, then GPU would be high-end. And if GPU can push 60+ FPS on 1080p but not on 2K, then GPU would be mid-range. So, mid-range CPU + top-end GPU = high-end build. Since Gigabyte UD750GM has nice list of good things and also bad things, it's a mediocre quality unit. If there were more bad than good (including price) it would be a bad unit and vice-versa. I, personally, wouldn't use it. While it can be used just fine for an office PC that never sees any high loads and also where the PSU noise isn't that important. But for home use in a gaming PC, where PC longevity and noise are important factors, i'd use and also suggest using better quality and more silent PSU. Different persons have different standards (some have higher standards while others have lower standards) and it's up to every person to decide how good of a build quality components are safe to use in their PC. Since i care a lot about all my PCs, i won't put a mediocre quality unit into my PC that fails to meet ATX PSU standards set in place for all OEMs to follow, so that the PSUs are safe to use and doesn't damage other components. In fact, i've gone above and beyond regarding PSUs in my PCs. Some may call me nuts that i payed €206.80 for a great quality PSU that sits in my Skylake build (Seasonic SSR-650TD) and my latest great quality PSU purchase for Haswell build costed €205.50 (Seasonic SSR-650TR), while i would've been safe with a good quality PSU that costs €80.50 (Seasonic GX-550). While that can be true and i could've saved a lot of money, i feel safe and comfortable that my two main PCs are powered by the best offered by Seasonic. Only for my 3rd PC, old AMD build, i slightly reduced my PSU quality standard and bought a good quality PSU (rather than great quality PSU) that costed €101.50 (Seasonic PX-550). In the end - your call. If you absolutely refuse to entertain the idea that maybe it's your PSU's fault - that's your prerogative. I can not help you if you do not want to be helped. Like it or not, but this much is a fact: unless you test with 2nd, good (or great) quality, known to work PSU - you can not rule out PSU issue.
