Two Beeps on startup

[BearSlayer]

Hello! Sorry for my basic English!

 

Yesterday i removed my GPU from my PC, now i do not have external GPU but i have on-board graphics (Intel i5-3570) 

i have vga cable connected from pc to my tv. When i turn on PC i hear two beeps, i know it's usualy because of RAM but i tested all 4 ram slots one by one and i still hear two beeps every time. 
I restarted cmos battery to times with jumper and even removed the baterry and i still hear two beeps on startup. 
what i do know is that's not RAM or CMOS problem. (I even removed hard drives and all USB cables unpluged) 

display stays always black and i cant get in bios to check for problem there. 
 

I do not know what kind of mobo i have, it's not writen anywhere on mobo.

Do you know what brand the motherboard is? That's usually enough for beep codes. Are it long beeps, short beeps, or 1 long and 1 short beep?

I assume it's a prebuilt since Lenovo doesn't make any boards, do you know what the model is?

I think it means there's a graphics card issue. Are you able to use Displayport? Make sure to turn on the monitor first then the PC, sounds weird but that can help weird stuff. When you removed the battery, did you wait 5 minutes, unplug the PC and hold the power button?

I don't have DP cable. I tried again to restart bios how uou suggested and i still get two beeps. I am out of ideas where is the problem.

The only thing I can think of is the CPU having bent pins. Take it out and see if it's bent. You will need to reapply thermal paste. If everything's fine, it's a faulty cable or motherboard.

I check CPU and there are no bent pins. I switched to Pentium G2030 and i still was getting two beeps. And now whats interesting is that when i remove all 4 ram cartridges pc is non-stop beeping and when i put in one i am getting again two beeps. Is it posible that all 4 cartridges are dead?

That actually means the RAM is fine. CPU is also fine. That pretty much leaves the motherboard, so that's what's faulty here.

 

What you can try is reset the CMOS by shorting the pins. Unplug the power, hold the power button for 5 seconds, touch the CMOS pins at the same time with the same screwdriver, hold that for about 10 seconds and try if it works.
