Hello,

I need help to detect if a CPU or motherboard is dead. I have tested the PSU on other system and works fin. The system with the problem sometimes boots for a minute or less and then it turn off (With the RAM). Some more times it just try to get on, no post picture or anything, it just stay on for a second or two and then it turn off, no beeps and no video or anything (With or without the RAM). Other times makes 5 beeps, then restart and do again the 5 beeps, but still some other times go off afer seconds, there is not a real pattern here.

My bet are the motherboard and CPU but I'm not sure if is just one or both of them are dead to replace them.

I don't know the exact model but is a 5th generation Intel Celereon and a Gigabyte GA-110M-DS2.
