PC works fine but a little tricky to turn on

[fredkarklin]

Hello there.

I recently upgraded my setup to a Core i5 4440, but as I was an AMD user, I changed the mobo as well.

Everything was running fine with my old setup, and so does with the new one.

Thing is: when trying to turn on, no video will display on the monitors and peripherals (keyboard, mouse) won't light up their leds. The only thing that happens is the coolers spinning and case leds turning on.

I tried to turn the PC on without any RAMs and you can hear the mobo beeping nonstop. If I try to turn on with the RAMs, you almost cant hear a beep, only a really really low one, just like it's not enough energy going through the speaker.

But if I remove both of my RAMs and put it back again, the pc turns on just fine. And so it goes until the next time I try to turn it on again.

I'm kinda lost thinking if it is a mobo problem, a RAM problem or a PSU problem.

My setup now is:

Gigabyte B85M-d3ph
Core i5 4440 3.1GHz
GTX 1060gb
2x4GB DDR3 RAM 1600Hz
Corsair cx600W
120GB AMD SSD
1.5TB SeaGate HDD

A single beep is "everything is ok, proceed to boot", so that's no a concern by itself.

Interesting you need to reseat your RAM for post each time - that would sound like either a defective RAM module (how do things look if you try with only 1x RAM module?), or a defective slot on the motherboard.

Sorry, I was not clear at all. When the pc does not turn on, even with the RAM modules, you can hear it beeping many times, but in an extremely low volume.

I tried switching both RAM modules to the other slots, but the same problem goes in. I think it's a little difficult to be a deffective ram module, because it was all working just fine one week ago, before I switched mobos.

I'll try with only one ram module and i'll come back with results.

The numerous beeps is "no memory installed", so it's either not seated correctly or either the board or RAM is defective/damaged.

I think I can discard the option that the RAM is not seated correctly because the PC is working just fine and then it stops. And the RAM modules were working fine last week, so I think that it's not the case. It's extremely strange. It leads me thinking about some sort of voltage problem, so it can be realted to PSU. Maybe the MOBO connections are some sort of deffective, so it won't deliver the correct amount of power.

Can you suggest me any tests that I could perform by my own? I'm trying to find out perfectly what is the problem so I can use my Warranty.

Also, thanks a lot for your replies! Really helpful!
