Hello, So my i7 7700k and z270 system started giving me problem since the last 3-4 months. The cpu is not giving display, but the system boots to desktop. Changed the motherboard, worked fine for some days, but again same problem occured. So the cpu is the culprit I guess, its damaging something on the motherboard. Although I don't overclock. Anyways, So for the time being I ordered a Asus b460m and i3 10100 combo, fairly equal to the 7700k in performance. I am waiting for intel to launch 11th gen to see if they do bring pcie 4.0 otherwise I'll go with ryzen 4000 series. I only game on my PC so intel seems more apt for my usage. But the main question is, since I'll be changing the cpu mobo, do I need to reinstall windows..??? Will it not work properly if I dont reinstall windows. I am avoiding to reinstall windows since its a tedious job to do.
