Okay so I am facing some issues with my PC.
From past 2 weeks my PC is giving frequent reboots.. For a fresh start it works fine for 45-1hr. Then suddenly it reboots without warning and then it continues to reboot after 2-3 mins.. I have checked the RAM stick in another PC it's working fine. Same with the air-cooler which I had Installed recently.. I thought that the new air-cooler is not working and maybe it's coz of heating issues that PC is rebooting over and over again, but I installed the old stock cooler and yet the problem is still the same.
Then I formatted the PC with Windows 7 (previously Windows 10) fresh new installed and then I started to download the updates and again it rebooted..
It will be really helpful if you help me with a solution to what exactly is the problem in the hardware.
My rig:
AMD fx 4300 processor
GA 78lmt usb3 mobo
HyperX fury 8gb (4gb each) RAM
Radeon Rx 460 4GB nitro GPU
Corsair vs550 SMPS
WD blue 1TB 7200rpm HDD
CM Hyperx 103 blue LED air-cooler
