Hi if somebody can help me
My pc just reboots on random times and sometimes it just wont turn on all the fans start spinning but there is no beep. Other times the pc just reboots fine. This has been happening for the past two months it just started happening while my pc is turned on it will just randomly reboots. When running games it reboots more frequently. I have removed the gpu tested and the pc still reboots. It also isnt a hdd issue because i tried to install windows on a different hdd and the pc wouldnt boot up to windows installation sometimes. I also turned on the setting that the pc will give a blue screen when an error occurs but no blue screen appears the pc just shuts off instantly and restarts. Im thinking that it is a motherboard or psu issue. There is no bulged capasitors on the motherboard i checked and i also pushed on different places on the mobo to check if there might be a fracture but nothing. How can i find the cause of the problem? I dont have a extra psu to test if it is the psu. Sry for my bad english
