while home for the weekend one of my tasks was to replace the PSU of an old (2001ish) emachine. I decided the best way to do this was to get my psu upgrade, and give the emachine a swap with my stock psu (gateway... something, newish, (2008)) I swapped my psu out, powered the computer up, works fine, swapped my old psu with the emachines, no response (same as the old psu). is that as good of a diagnosis as I am going to get? there is no way I can put the emchine psu in my new computer (24+4 connection), also, would it be a problem if I put a 28 pin connection onto a 24 pin mobo? I vaguely remember doing it in the past, but if I didnt, could that be a cause of the failure to power on? (though I didnt even get to bios screen)

thanks alot, and if one of the mods wants to close my other post, I cant figure out how to delete threads, but I noticed it was already modded by vern, so if he just wants to close it out, I've gotten my answers

thanks again again!
