PC Froze then Died

[tasos.lan]

It randomly froze,i restarted,it froze again and after doing the process 2-3 times it died.

It starts up,no video output(Screen goes Power Saving),everything spins normally(Fans,GPU,CPU,HDD)
It's been disconnecting the keyboard randomly(I blamed it as faulty hardware) but it then started disconnecting the mouse before it died.
I pulled everything apart and cleaned it,placed one stick of ram at a time,at different slots,tried on board graphics,nothing works.
(Doesnt even get to bios)
I really don't know what's wrong,the GPU had been artifacting 2 years ago,but works fine now.

The ram i had purchased was causing blue screens.

In general,Murphy's rule really applies to me.

wonder if it's that psu, or if the psu failed and took other things with it

Bad things happen to those that use poor quality power supplies. That PSU isn't even rated to deliver 450w where it counts.

System wattage is about 430w.
It had been running with an FX-6300 prior to the i5.

My main concern is why it had the keyboard/mouse disconnecting.
(of course i'll be getting a new PSU to check stuff out then,i was mainly focused on the Mobo being bad)

I've just tested the voltages with a multi-meter,everything is in range(Within 80%).

Yellow: 12v
Red: 5.3v
Orange: 3,4v
Blue: -12.9v
Purple: 5.1v

but how can load test it? use OCCT and stress it. you can voltage test batteries that look fine too, but under load they sag and die

Sadly i cant stress test it because it wont turn on..I'll buy a new one and give info to resolve this for others with the same problem.

UPDATE:Changed both PSU and MOBO,still dead.

could you get another cpu to just test with, like a spare or something from a friend perhaps? i mean just to breadboard it, cpu, one rams stick and your new mobo.... see if it posts. then add the video card, see if it's the problem

Thank you for sticking with me,I sent the CPU back for warranty and will be replaced,i figured it's that since it wont post with new mobo,new psu and one stick of ram at a time.Since it has a built in Graphics chip it should had video output anyway.

Problems:Boot,no image PC seems dead but fan speed.Pressing the Restart or the Power button give no reaction.

Solution: Dead CPU.

it's funny because I had the same thing happen at work to me and we were surprised it turned out to be the cpu as well.
