computer slow on startup and browsing

My computer is extremely slow on startup and while browsing the internet. I ran defrag, cleaned out temp files, scanned computer for spyware. Nothing has worked, extremely frustrating when trying to do anything. I use firefox for a browser. It is not the latest edition, but afrai to upgrade for fear of losing bookmarks.

Thanks

Please, post some computer info:
- processor type, amount of RAM (hold Windows logo key, hit Pause/Break key)
- hard drive size/free space (open "My Computer", right click on hard drive letter, click "Properties")
- security programs in use (antivirus, firewall)

Hello and welcome to Bleepingcomputer.

Computer slow downs happen to most any computer over time and there are many reasons for why this happens unfortunately.

Some reasons have to do with what is on the hard drive.

It may have to do with programs demanding more memory and processing time

Anti-virus programs that run in the background to protect the computer from tainted programs and web sites.

Some browser related active-X programs have to run to help display certain content found on various web sites.

Then there is the various programs that decide to start up before the operating system has time to load properly.

Some have to do with the aging of the computer.

Hardware does ware out over time and slows the system down.

Electronic components on the motherboard start braking down, specially those electrolytic capacitors.

So there are a lot of factors that play the roll in a computer slowing down.

Including having too many programs installed, the more space those programs consume, the slower the system gets as it reaches out to the wider bands of the hard drive.

You do not lose bookmarks when updating Firefox versions. It keeps all settings.

Use ccleaner to clean system and remove startup programs not related to anti virus or firewall.
