Help!!! New 2 month mac book pro Running painfully slow.

Firstly i live in New Zealand and i got my Mac book pro about 2 months ago. It is now running painfully slow (for example the circle ball of death when only using finder and basically taking 10x as long to do anything) and i am assuming that it is a hardware fault. But i thought i would ask the forums to see if there is any thing i am missing and any way i could fix it my self.

The model i have is
Hardware Overview:

Model Name: MacBook Pro
Model Identifier: MacBookPro8,2
Processor Name: Intel Core i7
Processor Speed: 2 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 4 GB

Have been looking through the forums at reasons why it could be running slow.

It has enough room left over 300GB.
I have downloaded OnyX and run and run that.
Have looked at the activity monitor and nothing seems to be running out of the ordinary.

Am stumed about what to do any help would be greatly appricated.
Thanks in advance
Josh

I'd try the usual stuff first - SMC reset, reset permissions - how do this all details on Apple website.

Check your Dashboard. I have a feeling your widgets may be consuming a lot of resources. Try closing all your widgets and adding them back one by one and see if you see a performance drop.
