Program lag & thumbnail issues, potential faulty/dying hard drive?

Okay, so I'm not at all good at this sort of thing, and I never seem to be able to find quite what I'm looking for on Google, so it may be an obvious answer for most of y'all, but please bear with me and confirm or deny.

I have a custom-made PC tower, it's been pretty solid for the couple've years I've had it, but I've noticed an annoying trend over the past month. I'm an artist, so I do a lot of visual work with Photoshop and Clip Studio Paint and the like, so I have tons of image files on hand that I regularly access. Recently, all my thumbnails apparently deleted themselves, and have been an unusually laggy and slow pain to repopulate (it was a pretty fast and smooth process previously). And just when I thought I'd finally gotten them all taken care of and we were back to normal, a couple weeks later they've all deleted themselves again and now I'm having to go through the process all over. That green bar in the top of the window sits there forever, and the files will sit there forever and ever as they try to chug along and create new thumbs a bit at a time.

I regularly dust out my tower, run disk fragmentation, check my antivirus software, clear out temp files, run little programs like ccleaner, et cetera. I've checked various settings in relation to image thumbnails, and nothing seems to be amiss there. It's worth restating that this is something that just recently started, and wasn't an issue at all over the past few years on this computer. Literally nothing I do or change or update has done anything to improve matters.

But I've noticed other little things, too. Certain programs occasionally don't boot up as quickly as they used to. There'll be little lag spikes when I open up an image file, or long, briefly-freezy lag spikes when i go to browse for an image file to post on a social media site, or load a song into a music player/game program. Sometimes it feels like when I restart my computer, it takes a little longer to boot up and fully load in than usual. It's all very subtle and spread out, but noticable. The thumbnails are the biggest annoyance, but I feel like there's a slow but steady build-up of other issues coming to light that may point at something.

Specifically, I suspect it's one of my Hard Drives. I have three; D:/ and E:/, which were respectively pulled from an older computer and purchased as an extra backup drive, and my main C:/ drive, which came new with my custom built tower. Last night I installed HD Tune, and ran a check on all three drives. D:/ and E:/ looked very normal to me, as far as I personally can tell; here's one for example:

But this is what I got with my main C:/ drive:

I'm not very good at reading this sort of thing, but I definitely feel like this is Not Good and something's up. Would I be correct in assuming from all these issues I've been having and the HD Tune test that, despite it being the newest of the three, my C:/ drive has either become very faulty or is even in the early stages of the process of dying, and needs to be replaced? Or is there some other completely different problem going on and I'm barking up the wrong tree?

TL;DR: Is my C:/ drive busted and in need of replacement?

    By 'those ones' you mean D:/ and E:/, right? Really? From what I saw with the HD Tune test and just general observation, they seem fine, while all my suspicions and the issues I'm having point towards it being C:/ having trouble. Like, the test results I got for C:/ seem like they're pretty weird and Not Great, unless I'm just completely misreading them. Am I really looking in the wrong direction?
  3. check all 3 of them with short and long test even new part could be defective .
  4. are there really no other answers or suggestions for this?
  5. Actually, I'm going to go ahead and call this resolved. After days of thinking and deep digging, it occured to me that my antivirus software had relatively recently been updated to a new version. I uninstalled it, and hey presto, my computer starts up quicker and my thumbnails all load normally again. Despite my carefully chosen settings it looks like the latest Ad-Aware update got pretty aggressive with how it handles things, even if you don't have it set up to launch with your computer.

    so it is bloatware parts in the antivirus that made all this .
