you cleaned this computer? I mean, opening the case and cleaning out all the dust from the fans, air vents, and around the circuit boards?
Have a look at the video here to see what I mean;
Whilst you're looking inside, look out for leaking and blown capacitors;
Also, what do you use to secure against hackers, viruses and other malware?
I have a dell dimision 8400, running XP. Bought around 2005. After start-up, the machine will freeze-up. Nothing works, I have to shut it down by during off the master electrical switch. The start button has a yellow or amber light, if that light stays yellow, the machine will run and the fan will begin to become very loud. I have to turn it off at the master switch, nothing else will work, it is very difficult to get it to start up again, the start button will change from green to yellow (load fan) nothing on the screen, this has been going on the the past week. It is getting more difficult to get it started, and it does not last very long before it freezes-up. Any help or insight would be appreciated. I have not installed any software lately, I think the last software was turbo-tax back in Nov 09. Thanks for your help.
