Does daily 16 hour downloading affects pc health??

[official]

sometime voltage fluctuations may be held reponsible..or it may be simply coincedental...
i download too..and my pc runs almost 16-20 hrs a day. Some time i run it for 2 to 3 days.
Previously i had Intex 450 watt psu....but then i got a Cooler Master 500 watt.. no problem till now..had been running for last 2 years. Oh i switch off my monitor when not in use.. i hav VA1903wm.

I keep my pc on 24x7.

I am yet to suffer from component failure due to overuse.

I do however suffer from large power bills.

Just give it a reboot once in a few days if you are on windows.
