Desktop PC Performance Running Very Slow and High CPU Usage

Hi,

 

PC details:

HP Pavilion Elite m9292d

Windows Vista upgraded to Windows 7 Ultimate

 

My desktop pc is facing problem before (Vista - 1st time) and after (W7 - 2nd time).

1. PC is very slow when Windows logo starting

2. Desktop performance is very slow

3. CPU usage is very high as 100%.

 

I have tried many solutions from the forum, but it was still unable to solve my PC.

1. Hardware Diagnostic Tool - All test PASSED

2. Troubleshooter - but no error

3. Msconfig - uncheck unimportant startup

4. Defragment, Scan Disk Error, Disk Cleanup - completed

5. Register Booster, Avira, Avast anti virus - no virus or error

6. Format and reinstall Windows - same problem occured

 

Could you please help and provide any suggestion ? Could it be the HDD issue?

 

 

Thanks

JM

Hi,

 

Please use Task Manager to find out which service consumes CPU. We can work out from there

Hi BH,

 

The CPU usage (between 1 - 30) is very unstable as below items name.

 

svhost.exe

taskmgr.exe

explore.exe

System

dwm.exe

Isass.exe

Run it in safe mode and try Vipre antivirus trial, it saved me from getting a lot of slimy crap

Re: Desktop PC Performance Running Very Slow and High CPU Usage

Hello there,

I recently encountered same problem. i had to perform System recovery, because my Windows woudln´t start up, and since then my CPU is between 40-100% of it´s usage, google chrome is lagging, stops responding and working with it becomes very unpleasant.  Looking at task manager doesn´t really help, except chrome there´s nothing consuming memory, really, and anyway, bedore it didn´t matter. Woudln´t anybody know what is the problem? I scanned my computer for viruses, scanned with Advanced System care as well, and it doesn´t find any negative issues.

Hi,

 

Checking the processes on your system indicates Windows is indexing. That process will slow the system somewhat until complete.

 

Windows desktop management is also running and error reporting is active.

 

Give the system some time to stabilize.

 

Any clanking sounds from system?  You ran all tests and they have passed so the HD should be OK. However unusual clanking and constant disk activity could indicate an impending problem with the disk. Again, see what happens after indexing is complete.

 

BTW, I had the same problem with an HP factory drive (Hitachi). Replaced the drive (Seagate) and the symptoms wre corrected. The Hitachi drive became noisy and exhibited constant disk reads and unusual memory activity for no apparent reason.
