Gentlemen,
My 2005-vintage Inspiron 9300 Laptop started exhibiting high CPU (100%) usage around 2 months ago.. Following many suggestions in forums, the last step was to do a Clean Install of Windows 7 Pro, wiping the HDD completely.
The day after, the problem returned. The fan speeds up to maximum, and it does not matter what parameters are adjusted, and it happens when no applications are running. The CPU speed idles sometimes at 20 to 45 %, and then cranks up to 100% all by itself. At times, the performance gauge displays a continuous flat line at 100%.
Is there a fix at all?
I sent the machine to an after-market shop and they performed a fraction of the work I already did, and the problem never went away.
Is there a Dell-Authorized Service Center who might actually be able to fix this, please?
Thank you for your learned opinions.
