    Normally that means that the cpu is overheated. What kind of processor do you have?

Your cpu is probably overheating
turn off the power and unplug the computer and all periferals.
it may be dirty or the cpu fan may be going out. open the case, clean the fan with a can of air and cotton swabs. do not allow the fan blades to rotate freely when blowing them with air by holding them in place (or the bearing may go bad). you may also want to blow out the rest of the case as well and remove each card to clean them with swabs and air.
it will be slow work, but it can save you wear and tear on the entire system by doing so.
put everything back together and try everything to see that they work properly. if the problem persists, you may need to replace the cpu fan or risk damage to the processor.

My Presario 8000T power on then off


Hi there. Seems you already have a clue on what you are doing (good job). Try to test the system with another RAM stick. It may be a bad RAM, bad CPU or most likely, bad motherboard. But, before you change the motherboard itself, do the RAM test. It is the best shot. There is a device that you plug to the PCI port of *********** board but by the time you pay for it you are better off testing the RAM first. Good luck (please, if this helped, leave a comment).

Computer won't start up


sounds like the cpu is dead, if your fan was full of dust theres a high chance it wasnt working properly for a while which would of caused the cpu to fry from lack of proper cooling and also the dust in the vents would have prevented heat from escapeing so its highly probable that the cpu is dead try replaceing it, i cannot gaurentee that anything else internally got fried from the heat tho, i had a similar problem a week ago

Turns on, then shuts down before anything shows on monitor


Is there more than one fan inside the computer? Did you double-check the connection from the fan to the motherboard? Sometimes a computer will shut down if it doesn't sense that the fan is turning on, to prevent the computer from overheating.

Computer shuts down problem


When you take the cover off and start up, are all of the fans spinning? If the CPU fan doesn't spin, the system will shut down soon after starting to prevent over heating the CPU

Optiplex GX260 won't boot


I had the same issue and accidentally discovered a temporary solution. Unplug the power from the back of the machine, open the case and unplug the ATX power connection from the motherboard. With the ATX cable unplugged, plug the power cord back in. When you try to turn the computer back on the power light should turn orange and fans should be spinning, with it powered on plug the ATX connector back in. That should turn the computer off. Turn it back on and it should boot fine. You can even shutdown and restart, but when the power is unplugged you will have to go thru the same process to get it back up. This sounds crazy but it worked on mine. Good Luck!

D530 CMT minttower power problem


Hi, from your description it appears your power supply is ok.

Remove your RAM chips, clean everything with a soft brush or a can of compressede air [from computer store] Reinstall the RAM making sure it is seated firmly.

If this does not solve the problem, Are you using 1 or 2 RAM sticks? if 2 then remove them again and swap them around.

stick one in dimm2 and stick 2 in dimm 1.

If you only have one stick then beg or borrow another stick and try it. If all fails you may have developed a mobo problem.

Turns on, then shuts down before anything shows on monitor


I am an IT Tech of 11 years, I have found this problem and have solved this problem on the Gateway machines. Also works on the Gigabyte, ECS and Biostar motherboards in the same machine/s. It is not the memory, video, hard drive, or processor so rest assured. This is relatively an easy fix for those that are tech friendly. Remove the retarded one plug front panel power plug, remove the pins for the reset button and that does it. How you fix it from this point is up to you totally, but that does fix the problem. It is a common and frequent problem that mass producers have when developing wiring for them.
