Hello. For a while my pc (running win10 64b) has being doing strange things. The first one, months ago, was not recognizing the network card at startup. If I go to the device manager right after boot either no network controller was detected, or the one detected was a slightly different model from the actual one (intel 82579-LM was shown instead of 82579-V, with a yellow exclamation point next to it). In both cases, right click "check hardware changes" (in italian it's something like that, i don't know the exact translation) would solve the problem, after like 30 - 60 seconds. While in the beginning it was occasional, with time it started doing it more and more, now it does this every time i boot. I wanna note that at the time i tried a number of different things, like formatting, changing from win10 to win7 and to win10 back again, lots of different drivers, didn't work, so i believe it is some kind of hardware problem.
The second problem that appeared was this: every time the pc went on standby, and i woke it up, it would freeze, sometimes completely black, sometimes with the login screen already, for a minute or more, than start working again like nothing happened, before that i cant access the disk, and desktop icons of the links to that drive appear blank. This happens consistently, and every time the network card "disconnects" like i explained before.
The third problem was a loud noise coming from the secondary HDD, which i only use for music, movies etc., this noise manifests together with the previous problem, and ends exactly when I manually "detect" the network card.
The fourth and last major problem is pretty recent. Now sometimes even the cpu fan becomes noisy at startup, and i get a "CPU fan error" black screen, that prompts me to the bios with the f1 key. From there i just boot from the SSD where win10 is and all works normally.
It may be useful to note that once or twice when i couldn't access the hdd, i tried accessing a usb stick, and i couldn't access that either.
I'm am not an expert, but the variery of problems made me think of a motherboard problem. Since i don't have a lot of money though, I'd like to be sure that's where the problem is. I hope some of you will be kind enough to help me. Thank you.
