ok i have a emachine t2200. just read that emachines suck. anyways i had this pc for a few years. i already bought a PSU. because i thought that was it. what happen was nothing on the screen just the ring around the power buttom just lite up. i opened it seen a red led on whats does this mean? the only upgrade i done was a video card. that was in for 6 months then the cpu die. (22in acer screen) i mostly do on line shopping email etc. no downloading really. i read that the MOBO are junk. would that fix it?
