Frequently, this sound is caused by dust inside. Unplug the machine, open the cover and apply Dust Remover. The machine should much quieter.

My wife was mowing with our Husqvarna ride on CTH2038 and it started reving really fast so she disengaged the deck and ramp the throttle back to min but it kept reving so she shut it down with the key


Best thing I can recommend is to carry it to a trusted repair shop for them check it out for you.

Sound like governor control came loose or the governor self destructed. Without the age of the mower don't if the warranty will cover the repairs but the engine will need at least repaired if not replaced.

Laptop shuts OFF on it's own


Laptop fans DO NOT run constantly. They only turn on when booted up and once the laptop has reached a certain temperature. You should probably time how long for a shutdown, record your results. Let laptop cool for 10-15 between attempts. If it takes approximately same amount of time to shutdown between attempts it is very possible its overheating.
Other things like Viruses, software conflicts, and Harddrive problems can also be the culprit. take a look at the administrator event logs for any clue there. Event logs are in control panel under Administrator Tools.

I don't recommend trying to fix any overheating issue you may have, as that would entaiil disassembling your laptop. Unless you have a bit of experience in this, I would take it to a good repair shop.

Hope this helps you some. If so please rate my solution.

Mother board no display


Looks like the lights are on? Fans spin? Sounds like the harddrives spinning? The power supply is bad. has just enough power to light lights, and spin fans, but not enough for the processor. (No beep sounds, because BIOS hasn't done a memory count. It's not going to)

ALL the lights use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
The harddrive just sitting there spinning, uses about 5 watts.

Processors use 55 Watts to 125 Watts. Depends on the processor.
Not enough power to turn the processor on, the computer won't work. Computer isn't working there isn't anything to turn the monitor on. No Signal.

Your thermostat is bad. The default position is" on" so that you don't burn up your engine if it goues out when your running.
