With the long spell of dry weather I am seeing a lot of computers filled with dust.
Dust buildup causes overheating of components and eventual failure.
Check this one out:
(thanks for the pic Harriett !)
This machine died due to a failing CPU and Hard Drive.
Most modern CPUs have a built in "thermal shutdown" feature that cuts power to the CPU if the temperature reaches a certain level.
To most users this would appear as the computer "hanging". If this occurs too many times the CPU is eventually damaged.
Hard Drives have disks inside which spin at around 7,200 RPM and overheating can cause bearing failure or electronic failure.
The machine above had both, resulting in a total loss of data.
Dust can also get into RAM memory slots ot Video Card slots causing glitches..
Dont place your computer on a carpeted floor or in a dusty environment.
Check the air holes in the case for dust buildup and gently vacuum it away.
Listen for "rumbling" fans or "clicking" sounds coming from the box
Get your computer professionally cleaned at least once a year.
Thats it for now..... Keep it Clean !
