so recently been playing minecraft and other low end mods after i heard they updated the villages and brought use to the vindicator outside of the woodland mansion.Any ways i played the game with google /youtube playing some stories and after loading a new world my monitor became black and the story suddenly stopped and my pc booted. this is the same with doing a gpu stress test and i remembered my gp is quite damage and so i decided to swap it with my lower end but fully functional gpu but to no avail then i ran a hardware temperature and power monitor and my cpu is 80c-60c on ideal and 110 on gaming or sometimes when i just run google but this is the same with back then it ran perfetly with still 100c
my specs are
gigabyte motherboard
gt 730 old gtx 1050-damaged (the 1050 is functional but it is lightly damaged so i thought if i used it more it could break)
amd a10 7700k
8gb of ram(100% usable and not damaged)
1tb hhd
generic heatsink
250-350watt psu
note:even if i just play minecraft and my cpu temp in the monitor says 60c-100c it still crashes and reboots but not when i just watch in my pc also note sorry for formatting im new and i posted a similar post too but managed to fix it
