I'm working on a Emachine. Well, the computer will power up but won't give any post beeps. I've been in another forum and got suggestions on what to check and how to check it. What i came up with was a bad mobo. So, i ordered a new mobo and new processor just to be on the safe side. Well, when i first got the new parts, i still got no post beeps. Came down to being a bad mobo, or so we thought. Sent the mobo back and got another mobo and still nothing. The first thing i tried when i got the new mobo back was installed the processor, fan and heat sink. Installed a new memory stick. Hooked up my known good psu. The power switch from the case. I did all of this with the mobo out of the case to make sure there wasn't a short or grounding issue. Powered it up and still nothing. So, does anyone have any ideas as to what else i could check or maybe even what the problem is? Tomorrow i am going to try the processor in my computer just to make sure it's good. Any help would be much appreciated.
