Having problems with your HP M490N PC Desktop ?
Computer turns on leaves message and cuts off
\015 I have a HP M490N computer. When turning on computer I can hear the fan turning on and running hard. A message appears apologizing but says that the computer cannot connect to windows; that an electrical change may have caused the problem, but there was no electrical problems to my knowledge. Screen also has on it the safe mode option but indicates that the machine is shutting down to protect the files and the computer. Once the machine cuts off, if you try to hit the on/off switch again, the green indicator light comes on, the amber light flickers on and goes immediately off and the machine turns off. If you let the computer rest for five or ten minutes it will repeat the initial message that I mentioned above in the third sentence of the post ("A message appears . . .).\015
When u get into the safe mode try and run a system restore to a date earlier than 2 weeks> if that doesnt solve the problem> disconnect all the external devices from the computer> other than the keyboard, mouse and the monitor> then whole restarting tap the F1 key to enter BIOS screen> hit F5 then enter> then F10 > enter> the computer restarts
This means that your cpu fan is facing some problems so its better change it or else your pc will encountered on and off. you can use it for 2-5 minutes then turned off automatically and you will notice the the lights is still on.
