Truthfully, I would like to convert my NAS to SSDs as well.

Get SSD/nvme They are now priced cheap, especially now on black Friday is fine deals too. Don’t need to be 4tb! Just 1 or 2 is fine (often 2tb are the same prices as 1tb or just a few buck difference)

HDD turns on like 5min, not to mention if the WIN decidyto do some background stuff… pc becomes unusable for all that time and nothing will help, you will just sit and wait half an hour till it does stuff! So yeah - get an upgrade and save your time ^^

You need to get your main windows on a SSD. Even an ancient CPU like a 4790k will feel snappier with a SSD than a fast CPU without one.

there is your problem. SSD prices are at the cheapest right now.

I said it’d be expensive to convert my entire 60TB NAS to SSD.

A 1-2TB SSD to run your OS on is a perfectly reasonable expense, and will make a huge difference to your experience running the system.

Hard disk drives are many orders of magnitude slower than solid state drives.

Back in the day, before we had SSDs, this is how a lot of things worked. We would wait a long time for programs to open, and the operating system would sometimes hang (long enough that it appeared to be crashing) when switching between workloads. It was a slow and painful experience.

If you’re doing the majority if you work off the HDD, it’s going to be very, very slow. You can use the HDD for data storage, like backing up pictures, movies, music, etc. and you can even use it for some older games, but you should absolutely be running any modern version of Windows off an SSD at this point.

There could be something else wrong, but I feel pretty confident that you’re simply underestimating how slow HDDs are.

From what you’ve said elsewhere it likely is your HDD but it’s still good to take a look at your thermals. In HWInfo click the ‘Sensors’ button. It’ll bring up a fairly long list of different readings covering power usage, utilization, temperatures, and more. Scroll down until you see your CPU and Core temperatures. The 12th gen Intel CPUs have a max temperature rating of 100C and will cut power and clock speeds if that ceiling is being hit. If you see any cores bouncing off that number (or close to it) when under load you have a cooling problem. It should usually be much lower than that though. Depending on your ambient temperature, case, and cooling solution it could range anywhere from 25C to 50C at idle. With any minimally decent cooling setup and while under heavy load 80-90C can be considered normal but a good cooler will usually keep you under 80C, sometimes significantly.

1000gb ssd is 40-50€? Im from Finland

While running Windows on an HDD will certainly make everything very slow and it’s a fact, it will not introduce freezes(at least long ones) and crashes. Sounds like your Windows installation might be borked or your hardware is not stable.

If I were you, I would start with a clean Windows install, including the complete wipe of your system drive.

SSD with a lot of space expensive? What do you see as a lot of space? Like 1 TB goes a long way and that cost 40 € which for pc parts is not expensive at all.

A 500gb ssd is like $25 USD. You can keep the hard drive for general storage, but don’t put the os or commonly used programs on it.

Cherche pas plus loin, faut pas faire tourner Windows sur ton hdd, ça pue la merde.

Un ssd de 500gb c’est à peine 30 balles par contre, pourquoi tu dis que c’est cher ?

500gb c’est largement suffisant pour Windows, tes fichiers tu les stockes sur le hdd.

Get SSD ditch hdd, have u set ur ram to 3200mhz from bios? Its prolly running 2400mhz out of the box u need to set thr speed

I’d look at your memory first.

Buy a cheap 500GB or 1TB SSD for your OS and games, Windows on an HDD in 2023 is really stupid and gaming will also not be a very fun experience.
