Chances are it is just the fan in the power supply that is going bad. It either has dust in it, or the bearing is just wearing out. Either way, you could open it up and replace the fan with a similarly sized fan if you are careful. Power supplies contain large capacitors that can cause injury. If your case has adequate ventilation, a dead power supply fan may not cause any overheating, but it may decrease the life of the power supply.

Very Constant Noisy Fan


If this is a recent change in PC behavior, then it may be over-heating.

When was the last time you blew the dust out of the case ? This must be done 1 or 2 times a year, (more if you live in a dusty environment -- desert.)

Get a can of compressed-air, disconnect all cords, take the side off, take the tower outside, (you do NOT want to do this indoors -- trust me,) and blow it out. If there is a 'shield' on the heatsink, remove it so you can blow out between the fins there. Don't forget to blow out the Power Supply.

Tip : When the can gets cold, then the air will begin to freeze at the nozzle and it will become less effective....so STOP using it when it's cold -- you are just wasting the propellant. It is best to use TWO cans, one at a time....switching when one of them gets cold.

Cpu fan noisy in scaleo p


You can order and replace the noisy fan.
It is not difficult to do and requires minimum tools.
Just be sure any dust or debris is removed from heat sink fins, power supply and air vents in the case. Check clearance and dimensions before purchasing the new fan. Just like Goldie locks you want it Just right. Not to big and not too small.
If you blowing the Power supply out with compressed air. (always a dust magnet) Be sure to hold the power supply fan with a wooden dowel or anything to prevent blades from spinning. Be sure to do all this with the power off and unplugged. Compressed air can over rev the power supply fan and damage the bearings. (you'll have another noisy fan within a short time if you don't.)
Good luck hope this helps!

I turned on my Dell Dimension 4700 computer,but the amber light started to blink . I held the start up button for 5 seconds and the light went out. I tried to start it up again and got the same thing,...


Vaughn it sounds like the power supply is going bad, try another known good working power supply. If that doesn't work then the motherboard would need to be replaced. If the power supply isn't giving the correct voltages that could cause the computer not to turn on. If the motheboard isn't able to convert the voltages properly then the motherboard could be faulty.

Dimension 4700 series does not power up??


make sure the power cord is plug in tight, or try another power cord.
make sure the fan at the power supply comes on. if it still doesn't power up, then you need to check the power supply with a voltmeter at the output pins.

No display and wont boot


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Power supply is easier and cheaper to replace.

Any fan that is making noise you would need to replace. There is also never a need to use alcohol to clean a fan. Some computer air or a light wipe down will do just fine.
If you have any other questions let me know.
Thanks,

Dell dimension 4700 video card upgrade problem


Be careful with this computer. The cooling system works by blowing air INTO the machine over the cpu then the heat slowly comes out of the holes on the side panel (on the left side of the machine). One reason the text may be blurry is because the video card is heating up too much. This problem is specific to this machine. Most computers have the cooling fan blowing the heat out of the case and not sucking air into the case. On the plus side at least this PC is near silent right? I would know since I own this machine. Amazingly silent it is.
