Hello, I'm not sure if this is software or hardware related (I'm guessing it's the latter) so I hope it doesn't matter too much if it turns out to be in the wrong sub-forum.

Three weeks ago my PC started lagging when I switched between tasks and taking longer time starting up new ones. It's most noticeable when I alt-tab from games, which makes the game lagg badly in the background and when I tab back the game laggs for 5-10 seconds (sometimes it outright freezes) before it resumes, but even outside games it's evident that there is some underperformance going on. When I have several tasks open and start a twitch clip for example, the clip often laggs a bit before it resumes.

I thought it was because of issues with my old graphic card (Radeon HD7970) and/or its drivers, or my old RAM (corsair 2x 4gb), and since I've considered replacing them for quite a while, I went ahead and did so this week.

But the issues persisted, and even outside the obvious alt-tab lag, my PC is underperforming.

Any help with pinpointing what could cause this background lagg would be greatly appreciated. I'll attach a dxdiag log, but if you need any more information just ask.

Thanks!

Hello Wisshard,

Can you post the brand and model name or number of your PSU for us.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.
 
Hi Wisshard.

Lets make sure there is no corruption in the file system.

Click Start< type Command Prompt in the Start search box, right click on Command Prompt and click on Run as administrator. After the Command Prompt window opens, type chkdsk C: /r and hit enter. Type Y to confirm that you want to schedule a Check Disk to run on the next restart. After the Check Disk has been scheduled, close the Command Prompt window and reboot the computer to allow Check Disk to run.

Then lets see what is starting up with your machine.

Please download Autoruns. After you download the zipped folder on your desktop, right click the zipped folder and click Extract All. After the folder has been extracted open the regular folder. Run the autoruns.exe program by right clicking on it and selecting Run as administrator. When you open the program, click the Logon Tab and then post a screenshot of all the startup entries on the Logon Tab in your next reply.
 
Thanks for the replies.

I did the Check Disk and it Scanned & Repaired the disk, but I didn't get any information I can relay from it. It just finished and then windows was started up as normal.

I attached a screenshot of my Autoruns Logon.

Do you have a link to your particular model of PSU, we need to see how old the PSU could potentially be + how it it should perform.

Couple of things I`m seeing in Speccy that you should check as a starting point, your RAM is only working in single channel mode instead of dual channel, what slots in the MB do you have the two sticks, it should be slots A1 and B1 which are the first and third slots away from the processor.

You have multiple keyboard drivers installed, uninstall all of the redundant drivers for keyboards no longer used, once we have had an update we will take a look at your voltages.
 
In Autoruns on the Logon Tab uncheck the following items:

Adobe Updater
Logitech Gaming Framework
XFast LAN
Razer Synapse
USB 3.0 Monitor
Battle.net Launcher
GPUBoost
OneDrive
Skype
Spotify Web Helper
Google Chrome
Windows Mail (both entries)
The Microsoft Windows entry highlighted in yellow

After unchecking those items, reboot the computer and see if there is any improvement.

I bought it 4-5 years ago I believe.

My RAM was in slot 3 & 4. I didn't think it mattered much, but I changed it as you adviced now.

I looked for it now, and noticed 3 generic keyboards in the Device Manager (which is weird, because since I re-installed Windows 10 a year ago I've only used this one logitech keyboard) and I uninstalled them. Is that sufficient, or should I do something more?

When I did that the lag I described was gone :).

I started up & re-enabled Skype, Razer, Logitech and Battle.net and that lagg is still completely gone, even with multiple games, twitch, youtube open and switching between them. Not as smoothly as I would've liked or hoped for but many parts of my PC is old so will probably have to update more of it to get to that point.

Thank you! I appreciate you taking your time to help me with this.
