Various problems.

[SnOwBunZz]

Anyway, basically, every hour or two, my internet dies for a few seconds. (Network disconnects.) However, this only happens on my computer, and not on my laptop nor my other computer.

i had that when my speed was too high for my line

Added to that, whenever I remove an audio cable or any cable from the back of my computer. It freezes, forcing me to reboot.

no answer on that one

Other random anomalies which may not be related but have happened recently.
- Failure to turn on. Press the button, fans don't even turn on. My motherboard has lights to show if power is being received by the indivdual components. GPU doesn't seem to be, however, the power suddenly cuts out after a few seconds, and all lights go off.

either you psu has not enough power, your psu got fried (friend had this)
or one of your power cables got loose on your motherboard (if one of the two isnt connected, it fails to turn on)

- Disconnection while torrenting. Before the constant disconnections, I used to have a problem with my computer where whenever I wanted to torrent something, I would disconnect about every half an hour.

this seems like your speed is too high (like i said before), or you network card is dieing (wich i never heard before, and my hardware teacher said he saw only 2 dead network cards in his whole life)

Quite annoying.

Anyway, any advice let me know...

i hope this helped you a bit >.<

let us know asap

If the speed was too high for my line, wouldn't it be effecting all of my computers? o.O

And besides, I'm using fibre optics.

My PSU is a 700W. Admittedly it was a cheap and crappy thing which probably has life-span of cheese. So, it could be that. I'll want to make sure first though.
Interestingly enough the only way to fix this problem is to unplug everything, then wait about a minute, then plug everything back in. So. PSU sounds likely.

Thanks for helping out, hopefully what I said should have shed some more light on the situation.

there might be a conflict between the Windows NetZero software and the device driver software that cause it to disconnect often.

if your computer reboot all of a sudden, it may be due to the cause of your psu not supplying enough power to yoru computer, or you have a damage hardware.

My PSU is 750W, all i need if i were to upgrade my computer to run crossfire ^^ i still havne't bought myself a new power bar with surge protection yet, i should really get one but the one i want cost quite a bit ^^;
