Today i was using my pc and my pc just froze i restarted it and it worked fine. I ordered some parts a week ago and they arrived today. I put everything together and it works fine but my pc froze again. I bought new motherboard, cpu, ram and power supply. I used old hdd, ssd and my old case. What could be the problem. PC works fine after the reboot. Also when i was using my pc some buttons on my keyboard didn't work, but when i reboot my pc it works. Maybe that's connected with freezing. I think it's not hardware but something with software. My ssd is three months old and hard drive is like 10 years old but my windows is on ssd.
