1 long beep 2 shorts beep no display

[hiIneedhelp1]

Okay so ive searched just about every thread on this issue and cant find any solution, so some help would be much obliged. This is not a new build and I recently took it apart it put back together and it worked for one day then this problem. Upon powering up my PC, currently using it outside the case but it failed in the case beforehand, it quickly shuts off then reboots which is when I get the 1 long beep and 2 short beep error with no display. Ive made sure everything is plugged in and seated properly

my specs: i5 3.40ghz 4670k
EVGA 780ti
asus z87a mobo
ts 550 psu

now ive tried the psu and the video card in different computers and theyre working fine so it cant be that. Ive tried resetting cmos and changed the mobo battery, ive tried using the intergrated graphics without the videocard installed and I got the same thing. ive read it could be a RAM problem but ive tried using only 1 RAM stick in all combinations of slots. Im pretty much giving up hope and might be forced to buy a new mobo but this is basically my last hope in fixing the problem, any help will be much appreciated.

Hi there

I would check The following That the processor is seated correctly Also check for any bent pins on the motherboard and the processor.

If all this has failed then try with a memory stick at a time in each slot.

Hope this helps

Lucky you I know the answer to this bios error code.

It means no video card detected in the graphics card slot that is placed in the motherboard.
So it may need to be removed from the slot and re inserted.

In extreme cases it can also mean that the memory on the video card is bad.
It is likely due to the weight of the card, that you need to unscrew the card and lift it up over some more and tighten the fixing screw through the bracket of the graphics card tighter, to the case.

If the card drops due to the weight, it can cause a flex, or bend of the pci-e graphics slot on the motherboard, so you get a gap or a bad contact between the fingers of the card and pins internal to the pci-e slot on the mobo you have.

The last is to check that the extra 12 eight pin Atx connector is connected properly to the motherboard from your Psu.
and that all of the Pci-e 12 supply's are connected from your Psu to the edge of the graphics card properly.

In most cases all you need to do is make sure the Pci-e graphics card is seated right in the Pci-e slot of the motherboard.
and apply a bit of upward lift to the graphics card its self when tightening the retaining screw that fixes the bracket to the computer case, at the same time as lifting the graphics card up.

One or the other will fix your problem I promise.

Tried both of those, same thing. I suppose I have to buy a new motherboard
