Title says it. 5 Year old system freezes for 2-5 seconds around every 5 minutes. Whenever it freezes, the CPU spikes to around 50% and GPU to around 15%(RTX 2070 RTX super, GTX 970). Doesn't really matter how much I have open. I do a lot of architectural design with 3d apps (Revit, rendering software, etc.) but the freezes occur whether I have modeling software, photos, and pdf's open, or literally just surfing the web (chrome). Anything I can check? Memory stays pretty constant but could that cause anything? Again, the whole system is 5 years old, but the slight freeze and spike in resources makes me think the CPU. Any advice would be greatly appreciated.
