Can't get into bios

[FifteenWheat061]

Hi there,

I have an issue with my newly built pc. It gets to the post screen, but stays there for about 2 minutes, after that it goes to either a black screen, or "yz:" and onece i got some random character too, which repeated itself if I pressed any button. I can't get into bios, I tried both usb and PS/2 keyboard. Tried 1 and 2 sticks of ram, tried reseating them, tried 3 different ram modules, tried reseating cpu, clearing cmos, getting "dirty power" out of the system. Tried removing all USB devices, and also storage devices. Checked all the power connectors, where I could, I'd plug in another connector.

While I'm waiting on the post screen it beeps 4 times with long pauses between them. Tried with onboard graphics, but when I try that, i get no screen, and 1 long, with 2 or 3 beeps after it. The same beeps happen if i do not plug any display into it.  I can't try other motherboard/cpu, because I have only lga 775. Also, the CPU activity LED is continuously on, when I power on the system.

 

What can I do, to solve this? Or what might be causing this? I read everything I could find, but basically nothing helped.

 

The specs for the pc:

Cpu: I5-3330

MB: Gigabyte GA-H61MA-D3V (rev. 2.1)

Ram: 4 or 8 gb generic ram (1 stick)

Psu: 600W Zalman

Gpu: Asus GTX 770 2GB

Your motherboard manual will explain what the beeps mean

I didn't find anything related to 4 beeps with long pauses between them. I found out that the 1 long + 2/3 short means either agpu or gpu error. 

 

Can this mean that the processor might be faulty?

It's possible.

Here is what I would do:

 

Unplug everything from the mobo that isn't required to boot, this means unplug all drives, the dedicated GPU (if your CPU has integrated graphics AND your motherboard has video out) install only 1 stick of RAM.

 

Then power on and see what you get.

Wow, now it says that the main bios is corrupted, and its now restored it.

 

Now it seems to be working now
