Having problems with your Dell Dimension 4700 PC Desktop ?

At Start up, beeps several times, won't boot.

\015 PC beeps several times, Fan gets louder and faster and PC never boots. The monitor would stay black (not even blue). Its intermittent, and occasionally starts like there was never a problem. Other times, just beeps and beeps until I turn it off (with the fan screaming along).\015

Answers :

This could be an overheating processor problem,dependant on the motherboard and what the beeps mean.\015\012\015\012The fan speeds up to cool it down, there may be dust collected in the heatsink on top of the processor, check it and gently brush off dust.\015\012\015\012Check that the vents on the side are atleast 6 inches clear of anything for good circulation.\015\012\015\012To see if it is an overheating thing, remove both sides of pc and run it in an open space to see if the same thing happens.\015\012\015\012While you have the side off just check your memory and other peripheral cards are all seated correctly and not loose.
I had the exact same problem with my wife's computer. I used my air compressor to blow it out and it works good as new. I must say I am surprised at what a low tolerance this Dell computer has to dust.
At first I did not think it would work for me because there was so little dust in the machine and hardly any on the heat sink, just a light coating. But after I blew it out it solved the problem.
