It's official,i am hardware cursed
I buy before month or two ups for my personal computer where i work.Before i bought same ups for my router computer which is used to maintan constant connection on internet.Sudenly,ups start to produce some click noises.That didnt bother me,but sudenly he start to produce noise for backup mode(it goes piiiiiiiii every 10 seconds).That is strange beacuse that should appear only when electricty gone and everything is ok.Some time ups work normaly and then he start that sound which is very anonying.Especialy when i sleeping and then that sound awake me.And that sound is so loud it can be heard far from my room,and my bet is 1m from ups only.Imagine what's that mean when you are in deep sleep and that anjoying sound start.And yesterday,computer has been turned off itself.First i though ups is totaly dead so i remove and connect computer normaly.But ups was not cause of that.I look down under the computer,and notice proccessor fan doesnt not move!One piece of fan has been twisted and block fan to move.So i remove that piece and now is working.But now fan is loud so i would probaly need buy new fan beacuse i need silence since is computer in same room where i sleep.
Also i was just notice other ups also act same as this one ups but didnt notice that before beacuse i dont go to that room at all.Who knows maybe i will not buy other ups if i would know that.I realy dont know what cause that.
In history i burned a lot of hard disks,floppy disk,motherboards,network cards,dvd rom.etc list is long and i finaly though that will not happening again and now this.I realy cant understud why.
