System hanges why?

[Roofi_120]

I have a very very serious and important problem to my PC.
1. when i want to install some hardware to my PC for that purpose i usually open my PC and make the changes which is needed for installation, After that when i restart my PC and continue my activity browsing, gaming, listening etc my system stops, hangs, and then i press the shutdown button and restart my PC but again that problem repeats.

2. Some time i insert USB to my PC my system hangs and mouse/keyboard freezes.

3. some time the system hangs and a blue screen comes and the message come that "Continue Physical memory dump"

Please someone help me i have very serious problems

When it BSODs, you should provide the error from the event viewer as that would help determine the issue. You should also provide a comprehensive list of components (PSU, motherboard, memory, GPU, etc.)

make sure you have the updated drivers for your mb and devices. sometime it as simple as missing mb chipset drivers.
i would start with memtest and open hardware monitor and check the cpu and gpu temps.

How old is this PC? Has it ever not had these problems?

my pc used to randomly freeze while i was using it and i'd have to restart it, the problem was as simple as opening it up and cleaning the dust from the ram ports and the actual stick, worth a try

If your RAM isn't pushed in hard, that could be the cause, yes.
