Hello, about three months ago I bought a small pc case with an already included 450w PSU with the intention of building a home server in a future. Some days ago I saw a few parts on eBay at a good price and decided to go for it, but I can't make it work properly and I'm already desperated. The build is the next:
Asrock AB350M-Pro4
AMD Athlon 200GE
4GB
Ballistix Sport LT BLS4G4D26BFSE 2666mhz
I'm having a really weird issue that I never had before in any of my computers. The pc boots fine but after X minutes it seems like it's frozen, but I don't think that's the case. I've been trying to install Windows 10 but I only managed to do it twice, but then couldn't manage to get past the welcome screen (loading forever but with the words moving, not frozen), other times I get stuck at the installation process, not any special percentage, that seems random. I tried memtest86, the latest version on their page, it doesn't show any errors but sometimes it gets frozen (this time for real) but it usually pass three times without any errors.
What I tried to fix it:
-Ebay vendor told me to update bios; I did it, no change.
-Changed HDD, SATA cable and port, changed RAM from slot, it didn't solve anything.
Then I decided to use an Ubuntu Live usb, and I realized about something really strange for me. As I said, I don't think the system gets frozen, but after a few minutes (if the pc is turned on after a long time being off, it last longer) I suddenly lose access to the devices. Keyboard stops working (but mouse most times keeps working), no network connection, and GParted can't see the HDD as connected (I can see it at the start before everything goes off); as a side note, my keyboard is wireless and the light on the receiver is on at all times, seems like at least power is still on. However the system is still up, if the mouse is working I can open the settings, Firefox, GParted, app 'store', etc... The clock also keeps working and stays up to date with the current time. One time that I tried to re-boot into Ubuntu again after this happened but without waiting for a few minutes, it wouldn't work and there was a loop of an error message saying 'ubuntu pcie bus error data link layer'.
Where do you think the issue is? I just can't think of what could be the cause of this and I'm already out of ideas to test. I read this motherboard has some issues on some forums, but I don't think it's as bad as mine. The PSU perhaps? It has a 4pin CPU connector, the motherboard has an 8pin, but according to the motherboard manual it doesn't seem like it's an issue, it says to connect the 4pin connector at a certain position and that's all.
Regards.
