Hello,
I have an emachine T3624 desktop and when I engage the power button, the system will not come on. I changed the power supply and still nothing. I need to know if the motherboard is bad or if the cpu could be bad?
Thanks.
Hi Sorry to hear of the problem with your machine starting.
When you attempt to start,
1 do the fans, Power supply and CPU and any others start to spin up
2 any Led's illuminating?
3 Is the main power cable and fuse assembly passing current OK?
4 Have you checked the main power switch, and the actual on /off switch?
Let us know these results.

Hi,
This is not looking good, You are obviously getting power from your PSU to the Mobo, hence the green light, but if no fans are spinning up and no other case LED's are lit then the most likely cause is a bad connection/wire on your Mobo, a failed Mobo or an earth (ground fault).
Before you do anything else, check on your backup of important data, files, settings etc and if its not 100% up to date, accurate and reproducible slave the hard drive it to a known working computer (or put it in an External USB Hard drive case, or just use an cable with IDE/SATA connector on one end and a USB plug on the other, couple up a 5v power supply) and get all your important stuff safely copied.
If you are familiar with electrical test gear, and understand and can apply all the necessary personal safety and antistatic precautions then, you can do further tests. If you are not 100% familiar with and understand exactly what precautions you need to take, then it would be best to seek the services of a local competent technician. It is good to save money and to learn, but not at the expense of personal safety or the risk of damaging your machine or data.
If you are expert in these areas then it's time to test the output from your PSU, if this is OK then after reseating all daughterboards, cleaning the contacts and reseating them, (include your RAM in this, as well as your CPU and heatsink/fan and remove your mobo, from the case, connect it up in its freestanding situation (out of the case) and see if it will fire up. Be sure that no one can have access to the room where you perform this, as exposed electrical parts present a hazard to the machine and the risk of electrocution to anyone allowed near. Whilst you are doing this make sure you have cleaned out any dust using a proprietary air duster.

Thanks for the information but I decided to just put a new motherboard and cpu in the system. I wanted to know if I could just used the same hard drive without reinstalling the OS system and keep my data?

Probably not.
Because the MotherBoard and CPU are probably not "exactly" the same as the original.
Even if both the MotherBoard and CPU are the same "models" from the same manufacturer, they will be "newer" and very likely based on an updated BIOS/CMOS firmware that is different from that upon which windows was originally installed.

With the above dismal comment already stated…. It is "possible" that the same installation of Windows on the same Hard Drive "could" just pop right in and work appropriately.
You certainly won't hurt anything by trying it.
But be ready to do a format and reinstall as a "very likely" step in getting your machine up and running again.
