russellskanne: Yes. And other tabs like "System" etc.
Administrative Ereignisse (Administrative Events?) has a lot of red. Mostly Service Control Manager, some Winlogon, Security-SPP, few DistributedCOM.
Anwendung (Application?) has some red, Security-SPP, WMI, Winlogon.
Installation - nothing, it seems.
System - few red Service Control Manager.
Nothing in ACEEventLog, Hardware-Ereignisse, Internet Explorer, Key Management Service or Windows PowerShell.
I haven't done anything that requires "crawling under the desk and unplugging shit and rebooting" yet... I'm tired. :< I really appreciate your help though and I will do these things when my brain feels less like mashed potatoes.
russellskanne: Don't be afraid.
That's like telling a bunny to not be fluffy.
Aw... crap. Now I'm confused as to what to do next.
I DID make a lot of changes (at least it feels like I did) and when I do anything there's always a chance that I screw something up.
But.
First: No USB hubs, though I tried different USB ports for my mouse and a PS/2 mouse at one point.
Also, I did change my power plan, specifically the things you mentioned (CPU, USB, PCI - seems your problem was really similar to mine as I got these suggestions from searching for solutions).
WinU isn't allowed to update my drivers, I do that manually with drivers from vendors' sites. (AMD, Realtek/ASUS)
I regularly run Malwarebytes scans, full and quick. As for TDSSKiller - I'll check that out, although the description confuses me a little, what with renaming and commands. Could I just... I dunno, download and run the thing?
Start-up programs: I only disabled ones where I knew what they are, mainly things I had installed myself. The advantage to my limited knowledge of computers is that I tend to not touch things that I don't quite understand. Same goes for disabling things in the device manager - if I don't know what it is, I leave it alone. (So what I disabled were greyed out duplicates of my mouse and tablet, a printer that isn't connected any longer, those kinds of things. Nothing that made me go "What the hell is that?")
Memory and CPU: Assuming All CPU Meter is just about accurate, so long as I'm not playing games my CPU usage idles around 2-5% with my browser open but not used. Most CPU usage when I actually do stuff comes from flashplayer (when watching youtube videos) and SeaMonkey (my browser) itself. Highest memory usage by smss.exe, svchost.exe and seamonkey.exe.
...alright, what I'm getting at is, I don't know about that system restore thing. I'm not sure which point to restore. I don't know if some of the things I did were actually good. So far it seems none of them were particularly bad, at least.
Not sure how obvious it is but I can't think all that well right now so I don't think I'll be doing anything today. My inability to process thoughts aside though, thanks for your elaborate reply.
