AMD 7750 gives monitor Black Screen

[tobray5]

Hello,

So just recently i bought the AMD 7750, and i plugged it in to my computer. I started up the computer and I could hear the graphics card fan working and everything, but my monitor persisted in saying "no signal". I have tried updating my bios, that didn't help anything.

The Graphics card has a recommended Wattage of 400 and my psu has a wattage of 460. So I'm thinking that's not the problem. I have been reading other forums cant find anything to fix it. Help would be greatly appreciated

Make sure all necessary power plugs are plugged in (6-8 pin from PSU if necessary). If you haven't installed the drivers yet, you may have to do that as well as update Direct X, if necessary, and if your motherboard/CPU has integrated graphics, try using that to boot into OS and update drivers if possible?

 

[tobray5]

It donesnt need the extra psu pins but am i supposed to install the graphics card driver before i plug in the new card? if so i will try that

 

[Carobthomp]

I would try it, because depending on what you had before, it might not read properly. If that still doesn't work let me know, but make sure you update Direct X as well.

 

[tobray5]

I will try that. then respond with my results.

It is not letting me install the driver cd. i have run the install multiple times but everytime it doesnt show up in device manager display addapters

 

[Carobthomp]

Assuming you're using on-board graphics, if the card is not connected, then that makes sense. Have you already ensured you have enough wattage from the PSU?

 

[tobray5]

I am using my old graphics card right now which is the amd hd 5450. I have enough wattage the hd 7750 requires 400 watts and My psu supplies 460 watts.

 

[Carobthomp]

Right, I forgot that was mentioned above. The PSU has 460, but do take into consideration that the other components may take up more than that extra 60 watts combined, but it may not be the main issue. Have you tried using a different connection to monitor?

Also, is it possible to post some specs as well?

 

[tobray5]

I dont have the other cables that it uses besides an hdmi and yes the hdmi isworking with my old card. i have heard many people that run the 7750 with only a 300 watt psu. so im pretty sure its not that and the graphics card fan is running when i startup.
My computer is the dell xps 8300 8 gb ram ddr3.
processor intel core i7 2600
monitor dell st2320l.
windows 7 64 bit
anything else?

 

[tobray5]

I'm just going to send it back and get a new card probably a lower one just in case it is my psu that is making it not work

Your XPS can handle GTX660, so it is not "strong card", it is driver issue.
You say that old AMD 5450 is working OK?

Anything else I can help you with?

Your answer didint work. still got a black screen i guess illl send the card back and get a card that uses less wattage. thats the only answer i can think of now

 

[Kisianik]

This just doesn't make any sense, unless you got 7750 lemon....

 

[tobray5]

so are you sure its not the power supply?

 

[Kisianik]

so are you sure its not the power supply?

If your XPS is working good otherwise with old card - it is not PSU. 7750 reported working on even 165 watt PSU!
So your could not degraded by approximately 300 watt. Something else to blame.

Do you have any friends with AMD video cards - you could just insert yours into their PCs to test the card.

Not sure what else can be done...

 

[tobray5]

no all my friends have gtx cards. If thats all that could really be the problem i wonder if the card was faulty or of the hdmi slot is faulty i got it from newegg.com so ill probably send it backand get a new one and see if that fixes my issues

Can you borrow GTX card to try to install? You need stronger card than yours to see where is the problem>

 

[tobray5]

so why would i need a stronger card to see the problem?
Oh and actually i realize i am using the 5570 not tht 5450
