Needless to say, I'm pretty sure it's my motherboard, since I'm posting on this forum.. Anyway, here's the problem:
Occasionally the performance of my PC would just drop to a point that every open window (the browser, windows explorer, even the task and device managers) completely freezing and taking ages to respond, if ever. Restarting usually helps, but not always...
Here's what does help: turning off my network adapter. The second I turn off the network adapter every frozen window responds and the PC goes back to normal, only, you know, without any internet connection.
First I though it's a virus or just tons of malware, but I scrubbed the PC clean, with every tool I could find suggestions to online - none found any serious problems or threats. Then a friend suggested it might be a problem with the motherboard itself - my original network adapter is an on-board Realtek RTL8168C(P)/8111C(P) (the MB is a Gigabyte EP45-UD3LR, which is 7 years old at this point). But when I got a new net card (Broadcom NetXtreme Gigabit Ethernet), the problem continued. Everything would slow down to a point the entire PC would hang up, until you turned that network adapter off.
Now, this sort of made me question if the motherboard itself is the actual issue, since it's a completely separate net card, connected by PCIE (tried two different ports with the same result)... However, right now I'm connected to the internet through my phone's hotspot, and there are no issues what-so-ever.
Anyway, that riveting story aside, I'm just looking for a confirmation that it is indeed the MB, and not a software issue. My brilliant solution to the problem is to buy a new motherboard (and with it almost an entire new PC worth of hardware), which isn't cheap, and I am planning on keeping my current hard drive... It would really suck if the problem returned on the new (and expensive) PC...
