Model (or part number) of this "really good" PSU is?

If the problem lies with software, a clean OS installation is the quickest and simplest solution. It won’t cost anything. You can format the OS drive and start fresh with a new Windows setup.
Yes. Among many other software options, system freezes often occur because of networking drivers, GPU drivers, or third-party programs—essentially everything running inside the OS.
Heck, during my Win7 experience, I frequently faced freezes caused by Corsair iCUE software (which manages my peripherals).
Thanks for your reply. I received the MSI MPG A850G 850W 80 Plus Gold. Recently, the game crashed repeatedly, freezing for a few seconds before stopping completely. Music continued playing, but no buttons responded except for a hard reset. After resetting, the computer failed to launch properly since the bootmgr was missing. It showed an error when trying to access the SSD drive with the system installed. This is really confusing—I need to wipe this machine clean.
This isn't a particularly strong PSU. If it were, it would appear in this list. The article I found doesn't provide reliable information about the PSU, lacking important details such as precise ripple measurements per rail and focusing only on the overall unit. Additionally, key tests are absent—like transient response, hold-up time, inrush current, timing accuracy, 5VSB efficiency, vampire power, protection features, fan noise and speed. These aspects are typically covered in thorough reviews. Based on this limited review, I would consider the MPG A850G to be of mediocre quality. It's especially concerning since crucial data is missing. Unless a reputable source confirms its performance, it shouldn't be considered good. Regardless of what MSI or others say about it. For instance, it has a high +12V rail load regulation of 1.24%, which is significantly better than the MSI MEG A850GL's 0.51%. A solid review can help compare these differences clearly.
Missing bootmgr could lead to OS corruption or SSD failure. Also, please mention your SSD model—its specifications aren't listed. Similarly, your motherboard model isn't specified.
Just noting that the Gigabyte B660M you mentioned doesn't provide much insight.
Counting the available "Gigabyte B660M" models shows a variety of options.
If your MSI A850G PSU hasn't been proven reliable, it's reasonable to suspect a problem. Since the PSU powers all components, it's crucial. A poor PSU can cause hardware issues. If the problem persists, check if the SSD is present in BIOS; try connecting it to another SATA or M.2 slot. If it still doesn't appear, the SSD may be damaged.
Consider upgrading with reputable options like Samsung 870 Evo (SATA) or Samsung 970 Evo Plus (PCI-E 3.0 M.2 NVMe). Both are well-reviewed and reliable.
Personally, I wouldn't have purchased the MSI MPG A850G without solid reviews. Instead, I'd opt for a PSU backed by trustworthy testing. The Corsair RMx 750W is only slightly more expensive than your MSI unit.
