My wife has a 2.5 year old Dell laptop purchased from Costco. It has always run well. About 2 weeks ago it began to perform poorly and even had a random shut down. I made sure her AV was up to date and did a system scan and then also ran the Dell Diagnostic tool and all the hardware checked out.

So we backed up her files and did a full System Recovery to restore factory settings.

Restore was successful, Updates were successful, McAffee was uninstalled and Avast installed, etc.

But the system remains slow.

I checked the BIOS and everything seems in order. Ran the various Dell diagnostic checks (both the Windows one as well as the F12 low level tool) and everything checked out OK.

So what should my next step be?

Setup:
i5-450M 2.4GHz (2 cores, 4 thread model)
6GB memory
Windows 7 Pro

The system does not appear to be getting too hot. There seems to be adequate airflow but I will check the fan when I get home tonight.

Did you run the full Dell diags HD scan? A bad spot on the HD can slow things down.

The other possibility is that you have a rootkit.

I ran a full Dell Diagnostic and it passed everything. Avast and Malwarebyte have not turned up anything but I will look for a root kit specific app and do another check of the HDD specifically as I think that may be the issue.

Try something like OCCT that will give you CPU frequency. Maybe the system is throttling the CPU?

If so update the BIOS and Re-apply thermal paste on the heatsink.
