keystrokes and mouse clicks lag after PC has been on all night.

I'm having a frustrating problem that just cropped up a few weeks ago and I don't know how to go about diagnosing it. I leave my PC on all night to take care of iDrive and Synology backups. I've had this routine since September 2023 with no problems. I only ever restart my PC for updates or hardware and software changes, etc. Never because the performance goes bad.

Every morning when I come to my PC, I start my writing project for the day in MS Word. My keystrokes are laggy. My keystrokes freeze and then a second later everything I typed during the freeze shows up. When I'm editing a photo in Lightroom, my mouseclicks and scroll wheel freeze and then it's like they rush to make up for the freeze. I do macrophotography and I have to scroll in to see detail and it's frustrating because the scroll will take a half second to get there. With Lightroom, there is a standard preview where when you scroll in, it shows the detail better. It usually takes tenths of a second. Now it takes a whole second.

I check my task manager and everything is normal. There isn't anything taking up a disproportionate amount of resources. My RAM is only using 8 GB and my CPU is about 10%. Nothing is ever going up to 100%. My Malwarebytes is not running a scan. There is no heavy ethernet activity.
My cooling is fine. I run a large air cooler and I don't OC my CPU. My cooler ramps up during heavy activity and ramps back down like normal. My GPU fans ramp up during games or heavy editing and ramp back down fine. There's not a lot of dust in it. I dusted it this spring.

I don't have a lot of startup programs other than lightweight stuff.

I included a tasklist that I copied and pasted from CMD. "tasklist /FO csv"

One thing I thought it was, was maybe a Battlefield 2042 problem. I played Battlefield 2042 yesterday and this happened today. I'd have to test that out over a week though, playing it one day, not playing it the next, and seeing if the problem changes. Some people said 2042 has a memory leak issue, but I'm not educated enough in that to know if that's it.

I don't even know how to go about diagnosing this issue. One time, with a different issue, someone asked if my RAM is compatible with my motherboard. I've had the same RAM for 3 years. I bought it right after covid prices went back down. It's been fine. I even tested it with memtest and there were no problems. I don't know what an incompatibility would bne in the first place. I got it from Newegg and it's normal consumer RAM, not server RAM.



Any ideas on how I can diagnose this would be greatly appreciated. Thanks all.

Try clean boot state.

I turn my PC off at Night, and my TV.

Overheating can also cause this problem.

Install all Windows updates.

See installing the newest or oldest version of graphic card driver helps.

Scan for malware infections with MalwareBytes.

Could it be the CPU is thermal throttling due to high temps because the thermal paste has dried out? What does the temperature and utilization for the CPU look like?

In HWMonitor, all the temps for CPU readings have a MAX under 70C. And just now I finished a 30 minute game of Battlefield
