Computers Freezes Computer Case's Red Light (Hard Drive) stops blinkin

[Cryox]

My Computer freezes and stops working only when im downloading a torrent or try to stream!
The Red Blinking light (Which im sure is for the Hard Disk) stops blinking once these freezes happen
When it freezes sometimes i cant even restart it with the restart button on the case and have to take its cable out.The problem has been on my computer for a year but i havent tried fixing it.

I had a blue screen of death once but that was months ago.
Havent ReInstalled Windows even once since ive got it last year.

Sidenote: I sometimes have Administrator problems and cant do some stuff when i am the administrator could that be the problem?

Did you do system restore thingies before installing a program? Torrent downloads are mostly unreliable, and some even bring viruses.

• Try Using a different program for torrent-ing and try downloading a random safe torrent (e.g. Chocolate Rain )
  
• Scan your whole computer for viruses also. If it has found any, remove them.
  
• Freezing can happen if you're running too many unncessary programs. If so, close unnecessary programs (except your Antivirus), leaving the Torrent Downloader alone.

Let me know if the problem persists.
