Normally 3 beeps (might be one long and two short) means it's the video card, try another slot if possible.

If no other slot is available, then clean the contacts off the graphics card with a #2 pencil eraser, taking care not to touch the contacts afterward, and then re-insert the card.

if still nothing, try another video card.

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

04 Jeep liberty can only feel air conditoner when jeep is moving the other day the jeep beeped thee times and the overheated engine light was on now its off


Sounds like a fan issue. The engine and A/C are only being cooled when the vehicle is moving and air is flowing across the radiator and condenser. I would start car with hood up and check that fans cycle on as the engine gets warmer and a/c is turned on. Don't let it get too hot, and keep clear of fans and moving parts.

How to repair start-up on my computer


How long is shortly? If it runs and brings up the Windows Desktop and you are allowed to work for 10 minutes or longer then it shuts down, most likely the laptop is overheating. One way to tell if it is overheating is to immediately try to turn it back on after it shuts off. If it will not boot back up, it's overheating. If you let it sit and cool off for a while, then try to boot it back up and it does it successfully, it's overheating.Causes of Overheating:1) Dust all inside the computer. Fans clogged with dust, dust around the vents.2) Fan not working 3) The Thermal Past around the CPU has dried up or is too thin the keep the unit cool.When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

So I have a Emachine t2984 model... It was working perfectly till out of nowhere I heard two beeping sounds coming out the computer then CPU shut completely off. So I went to tried to turn it back on but...


you have done the right thing by cleaning the dust from your computers fans you should continue cleaning the dust from your computer as dust will cause static which can cause a computer lots of unforseen problems
the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.
make sure that your RAM is securely seated
test or replace all the leads that attach to your hard drive make sure the connections are secure including electrical extensions + IDE,SATA the ones that attach from your
((motherboard to hard drive))
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps keep up the good work

On the IBM Thinkpad 3 long beeps should mean "critical thermal" After it cools down will it start again?

Is the fan still working blowing air out the back or side?

My Thinkpad G41 does not boot up, nothing comes up


Hello

Have you tried swapping out ram modules? This would probably be the cheapest. And, a faulty ram module gives a beep code. Try it, and let me know.

Kind regards

Deep freeze computer inresponsive


it sounds like your computer power supply went bad.
go to your local computer store and buy a power supply, install it and you should be up and running.

that is if you didn't fry everything from running it without the proper cooling.

make sure that you have proper cooling fans in your computer, a fan outside will not do it.
It sounds like your power supply fan stopped working and it just got to hot and died
