My computer is over heat route to nifty.?

One of the most common cause is dust, lack of nouns flow, having it sitting on mat and the fibres receive sucked into the inlets.

Open the case, and verbs all the vent, fans etc, use a verbs air source to loosen the dust, and sensibly use the vacuum cleaner, be aware of static discharges.

Also place the unit on a thorny surface to improve airflow.

Check that you own enough fan in the armour to allow plenty of air circulation as capably.
Try cleaning it for one

or get a topical fan.
If it's a desktop workstation, then you should first check to see if the follower is working. If it's a notebook pc receive sure the fan vent on the bottom isn't mortal covered up when you use it. That's all I can enlighten ya!
Make sure nothing is contained by the way of the hanger-on or try even seeing if the fan is even working if its out of commission buy a new one.
