Solved Gigabyte 550 ti gpu no video after install

[fspsyco]

So I just bought a new gpu and CPU for my pc and when I finished installing it and puting it back together and hooking it up I started it up and came to see that the screen was still black but it sounded like it booted up fine the card is the one in the title And the CPU is core 2 duo e7500

The power supply may not have enough power to power your system with a 550 Ti in it.

 

[fspsyco]

One thing I did forget to do was plug the cable for the fan into the power supply and I just did that also I did earlyer try to plug the old gpu in and see about trying to install the drivers and the screen was still black

 

[TwoCables]

PSUs in pre-built computers aren't necessarily made to support video cards like this. What's the wattage rating on your PSU?

 

[Think Tank]

If you're using HDMI, try switching to VGA and seeing if that helps - or the other way around. That might narrow it down a bit more.

 

[fspsyco]

On the power supply its 250w

On the power supply its 250w

Hmmm... That card takes a 400W. GeForce GTX 550 Ti | Specifications | GeForce That could have something to do with it.

 

[fspsyco]

So basically I have to go out and get a new power source before I can use it hmm is there any way to use the old card in the mean time?

 

[TwoCables]

On the power supply its 250w

Yeah, that's nowhere near enough. To make matters worse, that's a cheap 250W PSU.

I want to help you select the new PSU because they are not all created equal. The world of PSUs is extremely convoluted.

The old card? Do you mean the onboard video?

 

[fspsyco]

What I mean is I have an older gpu that I have been using which was a gforce gt 7600 256mb and when I truer using it earlyer the screen stayed black

Oh no. It worked before trying the GTX 550 Ti?

 

[AddRAM]

Does the motherboard support the new cpu, stupid question, but if it doesn't, everything will work but no output to the monitor or anything else for that matter.

So basically you`re saying you didn't do any research before buying the new card ?

Omg yeah, what is the old CPU? That is, what CPU is the E7500 going to replace once it works?

 

[fspsyco]

It should because my pc had a a core duo in it before hand but it was a e4500 I believe

 

[TwoCables]

Can you try the E4500 with the 7600 GT to see if that combination still works?

 

[AddRAM]

It makes no difference if the pc had a C2 duo in it already. The mb HAS TO SUPPORT the new cpu.

You're probably right because the E4500 is a 65nm CPU and the E7500 is a 45nm CPU. Back in the old days, I had an EVGA 680i SLI motherboard and my first CPU was the E2180. It is a 65nm Pentium Dual Core, but it's practically a Core2 Duo because it's a Conroe chip. I upgraded to the E8400 which is another Core2 Duo, but a 45nm chip. This required me to update my motherboard's BIOS because a Micro Code update was needed in order to support 45nm CPUs.

I put the old CPU back on and the screen turned on so is there any way to get the new one to work?

You'll need to update to the latest BIOS. That's not exactly the same process for every motherboard, so yo can either figure out how to do it yourself (it's actually significantly easier than you might think), or you can tell us the exact model of your computer so that we might be able to figure it out and tell you.

Edit: In light of what AddRAM is saying, what's the model of your computer? Perhaps there's a list of supported CPUs we can find. I'm not going to ask for the model of your motherboard because I can see that you have an HP computer, not a custom computer.
