Hi, i have just decided to give my PC a lil more RAM going from 512mb to 1gb using 4 256 ddr's after adding 2 new sticks, i put my tower bak together. After putting back together, i went to start it back up hoping my machine would be quicker... but it didnt turn on, not even the fans move... :( as a result i feel it is the PSU that is broken... i plug the pwer cable in and switch on at the mains, when i do i can hear like a thud coming from in the PSU...not sure if this is normal but would like some help on this. If my PSU is broken, will any PSU work in it? if it is not broken, whats going on? My Machine: eMachine 8210 Windows XP SP2 3.0E GHz Pentium 4 HT 120GB HDD Ultra DMA/100 512MB DDR (before adding 2 x 256mb ddr) 128mb AGP ATI Radeon 9200 <----- (naff :P) as for other specs im not sure... Any help would be greatful Regards, Xp
