High baseline CPU usage (~50%)
Hello, I have a Vostro 200, upgraded to Win 7 Professional almost a year ago. Recently, I've noticed the baseline CPU usage has been really high, to a point where it's boggling down the system. It says the usage is about 50% when there's nothing running other than the start up programs
I've also used Real Temp to test the CPU temperature, which idles at roughly 52C. I have absolutely nothing running on the background
The only antivirus I have is the MSE and that's it. I kept this computer to bare minimal mostly because it's mainly my HTPC. But it's starting to affect the video streaming with the high idle CPU usage. Any suggestion will be much appreciated. Thank you very much in advance.

Under normal operating conditions, on a nonstackable switch, the CPU is busy at least 5 percent of the time. If the switch is stacked, the CPU is busy at a minimum of 7 or 8 percent utilization. In a switch stack, CPU utilization is measured only on the master switch. The number of members in the stack affects the overall CPU utilization. CPU utilization increases when a system process requires more time or when more network packets are sent and received.

Andy,
If you click the CPU column, you will see which process is using your CPU cycles. Your startup list, however, is pretty short. Aside from stupid Adobe having two completely unnecessary startup items, there is nothing there that needs to be changed.

Thank you, osprey4. I'll disable the Adobe ones and see, though it looks doubtful that those 2 are the culprit because I have had them since the very beginning and I just recently noticed the high CPU usage. In any case, if it's useless, might as well not starting them at the startup.
I've also checked under the CPU column. When it was idle, it says "System" using/fluctuating between high 40's to low 50% CPU usage, everything else is 1, or mostly 0%. I am confused. I did a thorough scan with MSE and it caught nothing....
Now I am considering my last resort to reinstall Windows and start anew.

Try this:
1. Open Task Manager
2. Click the CPU column
3. Task manager will list items by CPU consumption, from the highest down.
4. If you don't see this, click the CPU column again.
The top item should be system idle processes, and this will generally use over 90% at idle. If yours says 40-50%, there should be something else immediately below it that's using a significant amount of CPU power.
