Question Graphic Card sometimes work perfectly and sometimes dont


May 10, 2014
My specs

Motherboard - Gigabyte GA-B250M-D3H
Graphic Card - ZOTAC 1050 OC Edition
PSU - Corsair VS Series VS450 - 450 Watt

So, It's been 3 years since I am using my system without any problem, but since December of 2019 I am facing this weird issue with my graphics card, when I turn on my PC sometimes it works but after restarting or again turning on, graphic card doesn't work at all (fans also don't spin) no matter how much I restart, but after 1 or 2 or even 3 days it again starts and sometimes works perfectly for single-use (means when I turn off my PC and turn on it doesn't work) and sometimes it works continuously for 3-4 or 5 days but then again it stops working, btw - when graphic card works no matter how much longer I game or use my PC there is no problem display is clear, I tried cleaning, checking cables, I tried everything, but the problem is still there, please help me.
