Processor seems stuck....

Hello,

I have noticed that my laptop (Inpiron 1520) has suddenly became incredibly slow. After hours of investigation, I noticed that CPU-z is showing that my processor is not running at max. Please see the following screenshot

As you can see, the multiplier is always stuck at 3.0X, I have checked and my laptop is running at "high Performance". I also checked my BIOS, which is updated to the latest revision, and Speedstep is enabled. What is interesting is that when I turn off speedstep, which means that the laptop runs at lowest performance, CPU-z shows that the laptop is running at 1 Ghz at different multipliers > 4, which is still not my maximum speed.
I do have the latest chipset drivers and I tried many things with no avail. I would highly appreciate any help...

Thank you in advance.

Below are my computer specs:

 

I think your lappy is throttling due to overheating and the CPU speed is slowed down because of it. See the throttling thread in XPS section.

 

CPU-Z isn't accurate when clock modulation is being used to throttle these laptops. Give ThrottleStop a try for a better look at what's really going on inside your CPU. It might come in handy too if you want to give it a shot of adrenalin.

Since ur cpu is throttling it might be bcoz or high temps inside or maybe power shortage.chk ur ac adapter and if its all right do the following :
1.chk temps inside using a software like everest.
2.chk whether ur fan is working or not.
3.get ur heatsink cleaned and place a new strip of thermal paste(this will bring down the temps inside ur system)

Your problems should be solved till now but if its still not solved then its better to contact dell.
