I have a Compaq laptop. And I've been using it 2 years now. Then this day, it suddenly became very slow. It almost took 5 minutes from turning on to the log on screen. I click my username and it took 3 minutes to show the desktop. I click on my computer then properties to see if it is still showing 2 Ghz for the Core 2 duo processor. And 2gb for the memory. It took 10 minutes for all the information to show up. And its still 2gb and 2Ghz. So I may conclude that this is not a problem in memory or CPU. Its still running perfectly last night. And I have not seen signs of it failing.
Things I already tried:
Shutdown then turn on again
So how do I determine what causes this problem? How do I fix it?
