My PC wont start with new graphics card.

[Rom3boy]

Hey guys,

This week I just got parts to build my second computer. These are the parts

AMD Athlon 860k
MSI A78M-E35
Nvidia GTX 560 ti
Leppa N500

So I put the computer together and once I turned it on, it gave the sound of a long beep then two shorter beeps.(There wasn't anything on the display)

But when I switched the graphics card for an r7 265 it worked fine and the bios loaded up.

I thought that the graphics card was broken or something so I returned it and got another one.

But once I put in the new GTX 560 ti it gave me the same beeps and wouldn't display.

Any help would be appreciated, thanks.

One long beep, 2 short is definitely a vid card error with your mobo. Do you have the correct power cables plugged in? Believe the 560ti has 2.

 

[Rom3boy]

Yes, I'm pretty sure i have both 6 pin connectors connected. I just found out that the graphics card works with another one of my motherboards.

That's pretty odd.

It leaves either:
a) Power Supply, or
b) Motherboard

Sometimes you get weird conflicts. If you can try the PSU from the working system that would isolate your issue. So if it does work then I'd suspect the motherboard though I'm not sure why.

Right now I suspect the PSU as the prime candidate.

 

[AMDThunder]

Are you using the same PSU on both? If not, use the 2nd PSU from the working GPU/mobo combo and see what happens.

on my other computer im using a corsair cx430, but when The graphics card was working in the other motherboard, I had the Leppa N500 powering it so I think it has something to do with my motherboard.

Might be the PSU, with your rig, I'd want a decent 500 watt PSU, the Leppa only runs 408 watts on the 12volt rail

 

[Rom3boy]

Ill buy a 500 watt psu this week but what do I do if that doesn't solve the problem?

 

[AMDThunder]

I'm assuming I have this straight in my head.

So the only thing different between working card and not working card is the motherboard correct? Is there an updated bios available? You want to make sure your set ups are identical in every way. If this is a fact, and the only difference is the mobo... Think I'd start my search there.

 

[Rom3boy]

Alright ill update the bios and see what happens then.

 

[Rom3boy]

ok, I updated the bios and the computer started up with the new graphics card. Only problem is that the starts on windows instead of the bios and the mouse doesnt work.

Huh? Don't you want it to start in Windows?

 

[Rom3boy]

I feel stupid now.(mouse wasn't plugged in) Well updating the bios worked!

 

[Rom3boy]

Thanks everyone!

Awesome! Glad you got it working! Don't feel bad about the mouse. Think most of us have done something similar.
