Shutdown my computer will randomly shut down and will not re-start for 10 to 20 mins, sometimes it will run for a few hours sometimes it rund 10 15 min and then it shuts down again..

Bad ignition module heating up and failing.

u may have a bad motor windings problem, usually will rund for about 25 minutes to an hour then shut off, wait an hour and can run again then shuts off ? also check ur venting inside machine and to the wall a build up can cause it to overheat and then shut down? u may have to remove cabinet to see inside condition? which thermostats did u change, u may have bad hi-lo limit and cycleling thermostat

give it a few cycles to relearn its self- key on start run, shut down,start and run, shut down and start and check it out- Denny

I had a 1988 dodge Dakota ,and it did the same thing. I fould that the o2 sensor was bad. I am a self employed mechanic

Random shutdowns without a blue screen are usually due to a faulty memory module inside the PC. Download and burn memtest from memtest.org to a CD. The boot from CD and proceed to do a memory test.

What kind of choke set up is on it?

YES

suggest change crank sensor-rear of engine pas side

It might be a problem with the computer. I would advise going back to where you bought it and returning it to either get a new one or a different one. Glad I Helped!

i have the same problem...laptop randomly shuts down, but its even done it within a minute of turning it on so i don't think its a heat issue. Sometimes it'll run for over an hour with no problem and never shut down, but other times it randomly shuts down sometimes within a minute, sometimes maybe 10 mins, sometimes 30 mins or more ...its maddening! i'd love to find a solution if anyone's found one. Thanks.
