Having problems with your PC Desktops ?

Thermal Event On my Dell OptiPlex gx270 I keep getting an ''Alert - thermal event'' however, my fan is working fine. My system keeps shutting down when I try to boot up. After about the 5th or so try it will reboot and run fine.

Answers :

This is likely one of the following:
\015\0121) the thermal paste under the fan is dried up and needs to be redone
\015\0122) The case needs to be blown out of accumulated dust
\015\0123) the motherboard has an electrical problem (old capacitors failing etc.)
\015\012It could be all 3 issues.
\015\012If you are somewhat skilled the first 2 are easy.
\015\012The last one can be fixed in many cases
That could be in need of re-pasting the CPU with thermal grease. GET IT DONE SOON

have the heat sink cleaned and re pasted - if you feel un comfortable doing it call a local pc repair shop
