Desktop lag even with new GPU.

[kyleclippers]

So i recently started having trouble with my PC dropping performance drastically after about 30 minutes of use. I can also trigger the bad performance by running a game which will instantly cause my PC to lag until restart. But recently the problem has been getting worse and it does it even on restart.

I eventually narrowed it down to being a faulty GPU through forums etc... I bought a gtx 1060 and to my surprise, the problem still persists. Its almost like everything is in slow motion, especially when dragging windows around. I know that its not an overheating problem as all of the temperatures read fine and I have also reinstalled windows so its surely not a software issue.

I have an I5 3570K OC 4.2GHz with heat sink
8gb Corsair RAM
8gb Patriot RAM
an SSD and HDD 1TB
CX750 PSU
gtx 1060 6gb
ASROCK Z77 Extreme 4 motherboard.

Ive also found that when I use windows basic the lag goes, but it doesn't let me swap back to Aero. This isn't really an option for me as the screen tearing in windows basic is too much to handle.

Any help would be greatly appreciated as this has been going on for weeks and I just cant figure it out.

Update 1 - I took out 8 gbs or my RAM and left in the Corsair. I got 4 hours of use without the PC lagging and i thought it was fixed. It seems that if i move and swap the RAM each time this takes place, it takes longer for the lag to return. Maybe this is just a coincidence but im pretty sure it has something to do with the RAM or the Motherboard.


Update 2 - After leaving my RAM in the same slots, the problem gets worse. The lag happens as soon as my PC restarts and turns back on. However if I change up the sticks and position, i get a little longer before the lag happens.

For testing out RAM, use memtest86,

It may take some time to run it but it's the best software to test out errors in RAM sticks.

Though, i'm getting a feeling that your old CPU might be slowly dying. Components do wear out and perform worse as time passes, until to the point they fail completely.
Since you've overclocked your CPU, underclock your CPU some to see if you get any different result. E.g to 4.0 Ghz, 3.8 Ghz or stock 3.4 Ghz.

If underclocking doesn't help, look the solution to fix the dwm.exe high CPU usage. dwm.exe is the application that is responsible of Windows Aero and it may be the issue for your lags.
Your dwm.exe uses 22% of your CPU while on my Skylake build (with Win7 Pro SP1 64-bit), i have dwm.exe using about 0.15% of my i5-6600K.

I think you've hit the nail in the coffin with the dwm.exe. Im on aero now with no lag and its using 00 CPU. I will update when the lag returns to be sure.
