Why is my whole computer system suddenly extremely slow? This is a pattern that has been going on for several months: All of a sudden everything works in slow-motion on my HP Compaq nx7300 Business laptop (processor: Intel Celeron M). I'm almost certain it's no virus. Internet, opening folders, opening programs: everything goes very slowly and is so frustrating, can't do anything. Tried to restart both laptop and internet connection but nothing helps.
My laptop is several years old so I think there is hardware problems: I had HP Service Center in Hong Kong to do a quick vacuum cleaning inside it and afterwards it worked much better. But that was about two months ago, and now it's back to that sluggish state again, sometimes works perfect, sometimes is very sluggish.
Is there any emergency solution to this (I need my laptop to work on, translate for customers) until I've bought a new laptop? Such as optimizing everything that is possible to optimize?
I have Windows XP Pro SP3, 32-bit. I always use Mozilla Firefox and not IE.
