Windows 10: Computer constantly crashes despite EVERY test coming back green

TL;DR: After getting rid of malware, my already barely running G5 5587 is now crashing when playing Fortnite. I have tried everything and am beyond done with this. I dont know what computer info needs to be provided, but i have my most recent DUMP file, DxDiag info, and is currently running Driver Verifier. It has not found any faults i think.From the Beginning:I have no idea where to start with this stupid computer because its 5 years of torment. I have almost done all i can and i cant take it anymore. Id set it on fire if it wasnt my only heavy lifting computer thats how beyond i am with all

Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
