Windows 7: High CPU usage when doing nothing

High CPU usage when doing nothing

Task Manager shows CPU usage constantly above 50% while doing nothing.
Looking at processes, all I see is chrome.exe using 60,000 - 140,000K memory (it continually varies) and between 02 - 12 CPU usage.

Currently, while I write this post Task Manager shows this information:
CPU Usage: 55 - 85%
Physical Memory: 42%

Physical Memory (MB)
Total 4061
Cached 1721
Available 2337
Free 677

I ran a Kaspersky scan and also a Malwarebytes one and nothing showed up.

I followed few recommendations from the web, but nothing worked.

Please help,
Dual Trace

You have a 1.3 GHz cpu, surprised it even runs Windows 7

It runs fine, reformatted once three years ago and installed an SSD drive one year ago. It starts in less than 20 sec.
I don't do anything fancy and can't quite complain about anything, but I just noticed the high usage.
At work I also have Windows 7 running on a 2GB machine and idle usage stays under 5%.

Here is the summary:
Laptop: Asus UL50VT
Windows 7 Home Premium 64-bit
CPU: Intel U7300 @1.3GHz
RAM: 4GB
Graphics Card(s): Nvidia GeForceG210M
Hard Drive: CT250BX100SSD1 (that is 250GB)

Look at task manager which process is eating most CPU. high usage could be due to anything, but knowing which background program is doing it will help significantly. Tick the "show processes from all users" option and sort by CPU % to highlight the offenders.

A blind bet: Windows update set to automatically download usually makes svchost.exe go crazy

Make a snip of task manger with all windows closed and post.

Example.

My Windows updates are disabled.
Here are the screen shots. The yellow arrow marks the moment when I shut down google chrome.

Hi,
svchost.exe is eating your resources leaving little for Chrome to eat so it feeds off the rest leaving you with none = slow system.
Windows Update will not update and I've tried multiple fixes

OK, here are all the svchost I can see. I'm 61, it took me a while to figure out how to find them all.
The one currently showing CPU 18 and 1,741,840k memory most of the time stays at CPU 50, but the screen shot got it at 18.

I ended that particular svchost process by clicking on the End Process button and restarted the computer. For maybe 2 minutes or so things were pretty quiet, but then that process slowly increased its memory usage to over 1,300,000 and CPU also up to around 50.
How can I disable that svchost and make it stay disabled?

Stuttering and high CPU usage while downloading at high speeds

Very high CPU usage, causing very high laptop CPU temps (90c idle)
This problem began yesterday. I noticed my CPU was at 90C constantly with very high CPU usage (>50%). I had no major programs running. I rebooted several times and the program persisted. 1. I went into safe mode and everything was normal. So this rules out hardware issues. 2. I reformatted and...
