Acer Aspire L 100
System Not booting

I Have Bought a Desktop From Acer Aspire L 100 In March ' 2008 With A warranty Period Of 1 Year for A Investment Of Rs. 3- (Only for THe CPU).

Since November I Starrted Facing a Proble Of System Not Getting Booted. As Such I Gave It To The The Acer Service Centre In December 3rd Week Wherein I Have Been Informed That The System's MotherBoard Has An Problem Which Would Cost Me A investment Of Around Rs. 7000/- With No Warranty Period.

Is It Fair Enough to Invest Something Wherein We Do Not Get Warranty?

Is It Fair Enough To Buy A product Such As Computer Which Has To Be disosed After A Period Of Just 1 Year?

Is This A fair Business Policy?
