Pc Keeps Crashing

[MyaMatchak]

I upgraded my pc motherboard, cpu and ram. Before everything was fine and there was no crashing. Now I have crashes at random and there no special screen that shows just everything not responsive. I check the ram to see if it was that, stills crashes, I re-install windows 8.1, still crashes. I mess with power options, change thermal paste because there was too much, still crashes. I don't know whats wrong but if anyone can help solve this issue I will be grateful. Thank you for reading this message.

SPECS
fx 4100
8gb (2x4gb) ram
r7 240 4gb
msi am3+ motherboard ( I forgot the model #)
1tb harddrive
430 watt power supply

You upgraded your CPU/Mobo and RAM...... did you reinstall your OS?

If you didn't, and just moved the HDD with OS over, what system did it come from?

Also, which "430W PSU"??

You can move your mouse and the apps give a Not Responding? Or just everything freezes after a while?

Logisys power supply and it came came from a q9400 system which I currently dont have anymore.

I can't even move my mouse when it freezes. And it freezes randomly. It could freeze after 2 mins of use or 2 hours of use.

The OS, clean or from the old build?

Logisys could part of the issue too. 430W would be lucky to be >200W.....and your rig should be right around 200W.

I just reinstall the os so a fresh install I guess. Also power supply was fine with the other system.
