Extremely high end PC began running slow overnight?

[Redzero999]

Hello everyone. I have a build of a GTX 980 Superclocked and Intel Core I5 2500k. Everything was completely fine until I went to sleep. I went to sleep and left the computer on. In the morning, I used the PC and it's been running horribly slow ever since. To open any program, load a web page or do anything it can take up to 5 minutes for basic processes. I never downloaded anything or changed any program settings. I used HW Monitor to check my temperatures on my computer and my processor is running at 20-30 degrees while idle and my GPU is around 20-30 degrees idle. I don't have any clue what is going on other then possibly a virus which I don't understand how I got at all. I've been running Malwarebytes Anti Malware full scan so hopefully it might solve the problem. Does anyone have any idea what is possibly going on? I did a reset and even that did not help my computer. It booted horribly slow and shut down horribly slow as well while the restart was going. I've had this computer for nearly 2 years and never any problems like this until now.

Does it persist after rebooting the PC? I would check task manager and see if any specific process is using up a lot of your CPU/memory. Did any automatic updates install overnight? Something else you could check is event viewer, look in windows logs > system and windows logs > application and see if any events show up from the night that this occurred

Thanks for the response. I did do a reset earlier and it did persist after resetting. My PC also reset incredibly slow when shutting down to reset and when booting back up. I checked CPU Usage % in task manager and it's around 1-5% total CPU Usage. My RAM meanwhile seems to be completely fine as well and is hardly being used too. Last thing left for me to do it seems is check the windows logs. I also noticed when I went to start Google Chrome it doesn't load at all. Nothing pops up and I checked in task manager and absolutely nothing. Right now I'm typing from my Laptop.

Update: So I went to start menu searched for event viewer and found it. I opened it and the loading on my computer is literally so slow that even after 2-3 minutes I still haven't seen event viewer appear yet.

I would try chkdsk:

Go to computer, right click on your main drive (probably C: drive), right click > click properties, click the Tools tab, and under Error-Checking click Check Now and make sure "Automatically fix errors" is checked. You'll probably have to "schedule a disk check" and reboot

So now after trying everything including Chkdsk and not seeing any reports of errors or viruses I did a full shut down of my PC. I turned it back on and everything seems fine. *Shrugs* I guess the problem was I opted for a reset instead of full shut down. This was a really weird problem either way.

Update: It went back to being unbearably slow. I am so frustrated at this point I don't know what to do anymore. Also, I went into safe mode and everything runs buttery smooth in there. There's zero lag and everything is normal in safe mode. If I go back to non safe mode it goes back to the horrible lagging when trying to do anything. Chkdsk told me my hard drive volume was clean so I don't think my hard drive is failing.

The next couple things I would try:

Try creating a new administrative user, log on as that user, if it runs fine just migrate all files/shortcuts/bookmarks/etc to the new user (i.e. go to C:\Users\(user)\Desktop, C:\Users\(user)\Favorites, etc, and copy files to the new user)

Or, before you do that, open msconfig, go to the startup tab, uncheck all unnecessary items so that they don't launch at startup. Or you can uncheck a couple of the most likely culprits each time and if it runs fine after rebooting you've narrowed it down to one of those items. I know you said you have malwarebytes, but do you have any other sort of antivirus running? Like norton of AVG? If you get a chance list the stuff that checked in the startup tab of msconfig.

On the bright side, since everything is fine in safe mode that usually means it's a software problem and not any of your nice hardware

If it runs ok in safe mode, it probably means it's an infection or bad drivers.. Run a full virus scan, and if nothing is found and still having the issue, update your drivers... Windows from Vista onwards, can be very fussy when running on outdated drivers... so install the latest drivers from the motherboard manufacturer's product page > Support > Downloads.

Did you ever solve this? I too have the exact same issue and mine seems to have coincided with installing HWMonitor which you have mentioned. Boot time has been bogged down considerably and applications taking longer to open. Looking at resource monitor it seems that directly after boot a combination of the anti malware and steam client/games are reading/writing to the disk causing the 100 disk spike... Ive no idea what is going on but it's very frustrating

Try disabling BITS it tends to lag my computer so that everything i try to open takes like 5 mins to even appear on the screen and chrome lags like hell too. and BITS needs to be disabled always the computer is rebooted/restarted

I have the exact same problem did you ever fix the issue?
