I built my own computer and add a nice new thing every year or so. So i decided on a new case. So basically i unplugged everything. Made sure I was static free when unmounting my motherboard...moved it into my new case...remounted...reconnected all cables just as they were...and PCI AGP cards. Reconnected jumpers correctly. Plug in power cord...LED light on motherboard lights up. Try to hit power but the LED flashes off and on the fan runs for maybe a second...and my CD drives eject for a second also. I have a 128MB graphics hard...network card...CD Rom drive, DVD-RW, floppy and a couple sticks of 256MB DDR and a 512 on a XP athlon 1.4ghz. Im thinking the PSU is messed up i have it set on 230 i think. I have used different outlets and different power cables all having same effect. I think the PSU might be messed up if there a way to test the PSU itself? Do you agree with my assumption? Your thoughts and possible approach would be really helpful. My moms computer is soooooooooo slow.
