Computer is a fry’s GQ084 with a ECS 741gx-m mobo, running an Athlon XP 2800 proc. Was running 1GB of memory@333mhz, 2700 ddr, mobo has two slots with a maximum of 2GB. Purchased 2 compatible 1 GB sticks and unit would only recognize 1.5 GB in multiple configurations: ie: 512kb+1gb, 1gb+512kb, etc. Unit was running on 2 sticks of 512kb. I was informed by supplier of new memory that the cmos had to be reset by removing the CR2032 battery on the mobo, and then replacing it, and reinsert the memory. I replaced the battery and now the unit will not start: not a peep, not a beep, no hd spin, no lites, no cd rom lites, etc. Power supply appears to be good; removed main power plug to mobo and used a paper clip to jump the black and green wires and then powered up unit. Both fans powered up, cd roms lit up, hard drives appeared to power up. What is my next step? Is power supply weak/dying? cmos battery dead, proc dead? Power button at front of case dead? Unit was running like a champ prior to this disaster. I know this is a cheaper computer, but it has served me well. Please help, I need it for business. Power supply is a Hopely atx-25b-p2 max output 250w
