So I Have a 10 years old computer with worst specs available :P (I am a student and my parents don't find a good reason to buy a new one as they don't use it). Since a few weeks, its cpu started to power down due to a thermal event (overheating).I didn't take it very seriously in the beginning and just allowed it to cool down for some time and it started working just fine (except for a beeping sound on the first start after thermal event). After a few days, it started overheating frequently and I searched the internet for possible causes. I cleaned it thoroughly from motherboard to heatsinks and power supply. Although the situation became worse. Now it starts and is barely able to show desktop screen before it powers down again, and when I try turning it on again it makes a beeping sound same as the one it made before. The sound is somewhat like the police or firetruck siren. When I turn it on again after giving it some time (usually 15 minutes) it is again able to show the desktop. Sometimes I am able to work for 10 seconds before the cpu powers itself down again (same old story). I tried cleaning it again but it had no effect. Anyone with solution???

Do you see the processor fan spinning?  If it is Ok then I think you should try removing the fan assembly from the CPU clean with alcohol and apply new thermal paste.  It does dry out and get crusty, it may fix your problem.

Mainboard have autoshutdown on their system to protect your mainboard gets burn.
it's better to check on BIOS what temperature on your mainboard but hope your mainboard BIOS have this if not you need to run a temperature reading software, if you temperature more than 70 C its better to buy and replace new heatsink fan :wink:
