Processing slows down when the system is under stress.
Processing slows down when the system is under stress.
Hey there, I’m trying to figure this out. Lately I’ve been using my old PC again for some casual gaming, but I kept getting frustrated because the frames per second were dropping. I thought upgrading would help reach at least 60 FPS. I swapped the GPU and added more RAM, but even with those changes, performance stayed pretty low. I spent some time looking and found that the CPU was stuck around 1.2 GHz on average, even under stress. It never hit 2 GHz, but when I tried to boost it in BIOS, it only reached 3 GHz during idle. However, during a stress test it dropped again. I’m worried about the temperatures too—CPU reports 70°C on idle, which is high, and each core hits 95°C. I don’t know what to do next.
How long has this been happening? Verify the CPU cooler is correctly positioned and has sufficient thermal paste applied. Ensure the fan connects to the CPU fan header—not a case fan header—and operates at full speed when temperatures are high. For stock Intel coolers, noticeable performance should appear at maximum speed; if not, the fan may be faulty. Inspect for dust obstructing the fins and clear it. Repeat the same for any aftermarket cooler as well. Confirm the case is effectively expelling heat or the exhaust fan is malfunctioning. Based on the cooler model, idle temperatures should stay below 50°C during summer.
