TLDR: pc is exploding into overheat doing basic things like opening file search or webrowser and steam. Worked perfectly fine prior to july 7th. Need help as need pc to work, and not just gaming. Confused as replace thermal pads and paste. Starting to think maybe intel chip or a setting/software is the culprit. Thank you all again for the help, still no solution.

EDIT:pictures of pc case and pictures showing the temperture differences from just opening a program or continuing the malaware scan.

Edit2: Ok info people have wanted in in the above link. My room is starting to heat up cause pc. I just did random letters for pictures cause using my screenshot was getting into the red and freaking me out. I have to turn off pc, it goes down to low temps in seconds so I am starting to think it is some software issue, but I cant keep using it atm.

Thank you all who check out this thread, I am a bit freaked out as I need my pc to work from home. If this isn't fixed by monday I am in trouble. I already am penny pinching as it is and I built this pc from scratch into an old pc case. Everything is replaced, I dont know what else to provide.

Thanks for your time!

Edit3: pc is on the floor just as I figure out what is wrong. Neck and Back began to hurt during disassembly.

Edit4: No virus found after a 1hr and 30min scan spanned 4hrs from me pausing serveral times.

The mind Bender

This began wedesday july 7th 2026 after downloading a mod for the The long dark to enable save editing.(Look I beat the game already and wanted more fun to derp around). (Also mod has a good reputation and has been around since 2019)I played the game my pc stayed at a good temp of 118f to 121f. After the session was done, I quit the game and then left my pc idling in discord vc, to take a nap. When I awoke my pc was overheating at 212f so I promptly turned it off. Since then my pc overheats just from bringing up the default google or morzilla pages. Hell I cant even open steam without it getting hot.

To remedy this I went ahead and bought these products:

ARCTIC TP-3: Premium Performance Thermal Pad, 120 x 20 x 1.0 mm (Stackable to 2.0 mm Without Performance Loss), 4 Pieces - High Performance, Particularly Soft, Ideal Gap Filler, Bridging Gaps x2

ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC, PS4, Xbox), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive, Non-capacitive

and replaced the old thermal pads and paste in my gpu, thermal pad for my ssd, and paste for my cpu. Despite doing this, my pc still is getting hot from basic tasks such as doing a malaware scan or opening the file folders.

I have been slowly doing a virus scan of my pc, pausing every so often in case its a virus doing this. I have meticulously blown out my pc with an electric air blower every 3 months for 4 years so there was hardly any dust to blow out. My room has been at a steady 78f despite the heatwaves.

My pc is next to a wall yet even when I pulled the location. It did not help this over heating issue and in the past in the same spot it would idle fl studio and scrivener , steam, video software etc with no issue and 108f to 118f.

all other drives at 0% as not in use.

Current office room temp is 79f

Id also like to ad cpu temps return to 120f when pausing virus scan or quitting any and all applications.

I appreciate any help in understanding what is going on.

118f=47c 121f =49c 212f = 100c 79f = 26c
