The bearings in the fan or internal mechanism may have burned out. If the fan does not generate a cool enough environment, you run the risk of frying the processor and other motherboard components that are temperture sensitive.


Replace, don't attempt to repair.

Keep me posted.

Dell Dimension with E187242 stops running after variable times from 5 mins to 30 mins Running Win 7


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

I have a dell 1545, I open up the computer and turn it on and the on/off light comes on I hear the fan start up, dvd drive starts and stops.....the screen is black and now the only thing on is the on/off...


1. if you have a new hardware recently added ,remove that hardware to make sure it is not the cause of your issue. If after removing the new hardware your computer works it's likely the computer is either not compatible with the new hardware or a system setting needs to be changed to work with the new hardware device.
2. Make sure all fans are running in the computer. If a fan has failed (especially the heat sink fan for the CPU) your computer could be overheating or detecting the fan failure causing the computer not to boot.
3.check all the connections.

Hello
Sounds like you need a new cooling fan.You may be able to save yours with some electrical contact cleaner spray.
Remove fan and spray.
The cpu will heat up quick and shut down everything to protect itself.Im sure once you get a new fan you will be up and running again.
You may consider reapplying new conductive paste to the processor while you have the case open.

On My Dv5-1125nr both the caps lock and num lock keeps blinking when i turn it on. It's wont boot at all. What kind of hardware problem is this?


First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:

LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help. Caps Lock/Num Lock LED Component Tested Error Condition LEDs blink 1 time CPU CPU not functional LEDs blink 2 times BIOS BIOS corruption failure LEDs blink 3 times Memory Module error not functional LEDs blink 4 times Graphics Graphics controller not functional LEDs blink 5 times System board General system board failure LEDs blink 6 times BIOS BIOS authentication failure

Computer suddenly started running hot


I would look at the cpu's before judging the fans on this, also if everything checks out with the cpu's then why don't you try a compund that goes on the cpu before the fan, this compond is safe and will knock like 6-10 C off the top of the heat. Also You need two fans blowiing out and one blowing in and do not interupt the ariflow, make sure you have no holes,such as missing slot covers ETC ETC.. there is not real rocket science to cooling on this manner, Thank you

Trouble shooting


OC failure = over clocking failure. Make sure the CPU fan is clean, free from dirt & dust. Check CPU fan plug is connected correctly. If the CPU fan still stops after a few seconds replace the CPU fan.
It's harder to find just a fan to fit your heatsink, which sits on your CPU. It is easier to find a new heatsink \ fan combo for your Intel. Use your manual to find what Intel chip is on your board. Use that information & search google for a heatsink & fan combo. Pay close attention to how your current heatsink is mounted to the Gigabyte board.
