Windows 10: Sudden Drop in Performance, Massive Spikes in CPU Usage (Lenovo G51)

I have a Lenovo G51 which is hooked up to my home entertainment gear and used primarily to capture video either through a Blackmagic Intensity Shuttle using Blackmagic Media Express, or through a Hauppauge USB Live 2.0 using AmarecTV.

Recently I've started dropping massive numbers of frames every minute or two, including locking up the entire BME program. AmarecTV is nice enough to note usage in the status bar, and the CPU usage hovers around 25% for the most part - it used to do this for an entire three-hour VHS tape capture. However now, it's doing that for a couple of minutes followed by about 30 seconds of percentages well over 100, going as high as 180. And this is for SD tape capture: I used to be able to capture a couple of hours of HD video with no issues. Hard drive usage is in the single digits, so that's not the issue.

Explorer constantly spiking CPU usage for Win 10

Hi. Thank you for your answer. I tried all your suggestions, but nothing helped.

Clean bot seems helped at first but no after some hours spikes came back and now spiking more often with every hour of PC working.

Same happened also without clean boot.

Any other suggestions what to try ?

Just to let you know that I worked with Win 7 before with even more programs installed than now and I did not switched off my PC for weeks and CPU usage was lower in general not to talk about any spikes in CPU, newer noticed anything like that...

Thanks

 

Lag Spikes caused by CPU usage drops and GPU usage spikes after Windows 10 April update

Since the April 10th update for Windows 10, my laptop has been suffering from lag spikes that occur during simple tasks such as browsing the internet.

When looking at the task manager during these spikes, I can see that the CPU usage drops to around 10% while the GPU usage increases to close to 100%. I looked at what programs were using large portions of the GPU which turned out to be the 'Desktop window
manager' and the 'Client server runtime process'.

I've seen that other people have had a similar problem with the recent update, but not much in the way of solutions as of yet. Does anyone know how to fix this?

Thanks,

Jason

 

CPU spikes and performance lag


Hi everyone. During the past few days I have a problem regarding my computer performance.

Problem:
-My computer is getting random performance lags that last 3-5 seconds.
-The cpu usage will jump when it happens; anywhere from 50-100%.
-Large Ethernet spikes as well.
-It's completely random and is very hard to catch but it happens when I'm:
a. browsing the internet ; engaging in miniscule internet activities.
b. opening an application on my computer.
c. watching a video, both on and outside the internet.
d. playing a software intensive game.

symptoms:
-Computer slows but doesn't freeze
-the really bad spikes are up to 100% cpu usage; usually though they are 50-80%.
-Video sound gets distorted and choppy; like if you have an injured CD that still plays right through the scratches but gets all choppy sounding.
-often times the mouse pointer will, all of the sudden, be trailing during the strange slow motion performance lag.

I had the same problem for like a week and it all of a sudden got fixed without me doing anything. However after 3-4 days the problem returned.

Do you have any ideas for a solution. I scanned my computer with Avast Security and it found no viruses on my computer.

My specs:
- Windows 10 build 14393
- Nvidia GeForce GTX 960
- Driver version 375.50
- Intel Core i5-6600 CPU @ 3.50 GHz
