My computer is laggy and tries to crash

Go: Start - Run - type Msconfig and check boot settings and disable anything you don't need. Secondly check for any programs you aren't using and remove them. In my opinion run CC cleaner ( I find it the best not complicated and easy to remove once done with ) and clean your pc from a lot of junk files ( not everybody recommends using these types of software ). Finally scan your pc for viruses ( make sure you update before )... If you still have the problem I would suggest you format.

This could be a problem due to your hardware specs a dual-core processors clocked @ 2.20ghz should run windows 7 and browsing flawless... What is the amount of ram you have ? ... I saw that somebody suggested an ssd, it's a great choice but in my opinion it's costly ( to get a 240gb one ) and if your pc doesn't support sata 3 it would be kind of a waste of money because from 500mb/s it gets limited to around 250mb/s whilst an normal mechanical hdd is 150mb/s but that is up to you.

Hope this has been of help
