My Acer has been sucky for a couple of months, pretty hot in the bottom , high cpu usage, even slower than Hans’ ragged sluggish Dell, shut itself down while I kept it running big programs, even though I turned the fan in maximum working speed manually. reinstall the whole system, update the bios, none was working. Today It shuts itself down without running nothing, just left under the sun! which made me too panic to think about any consequence before I turn every screws in the back lid. A surgery on it is overwhelming –this incurable damned Acer.

Checking the hard-disk, memory as well as fan, found some dirts, cleaned them up and i got stunned after the screws in the fans being unfastened, look at what I have found---- the disgusting parasite inside this crappy fan box, I would say the design of it is definitely a failure. It works like a dust sucker instead of a cooler.

Excuse me to show this nauseous pic……

thus problem fixed, he is cool and i am calm...
