I know this is more of a general hardware question but as there is no general hardware suborum I put this here. My problem is as follows: I sent my desktop pc via UPS abroad to my new home and despite working generally without making beeps at the start, I had some blue screens at the beginning and the computer was really slow. After removing some dust from the CPU fan, cleaning temporal data, registry and updating both drivers and my antivirus program, it works quite good so far for basics like office programs and stuff. But games, in my case e.g. FIFA 17, are running really slow and lagging which was not the case before the transport. So I fear that during the transport, there occured some hardware damages. Unfortunately, I don't know which hardware part(s) is/are damaged. Most assumably the graphics card, RAM and/or CPU, but I don't know how to test it. Is there any software to detect hardware issues? Or do I have to take a look onto the hardware itself? In case of the latter, what do I have to look for to detect damages? Thank you in advance!
