Blank screen after installing radeon r7 250 graphics card in a HP Pavilion p7-1120 Desktop

[ Edited ]

I recently purchased a redeon r7 250 graphics card after getting tired of using the integrated graphics on my desktop pc. After carefully removing the cover and installing the graphics card, I found that after powering up the pc, nothing showed up on my screen. Every fan is working, even the fan on the graphics card. I have tried disabling the intel hd drivers that come with the machine, but to no avail.

Albert, welcome to the forum.

 

I believe that your problem is caused by the lack of wattage from the power supply unit (PSU).  The card requires a minimum of 400W to operate properly.  The existing PSU is only 300W.

 

Please click "KUDOS Thumbs Up" if I have helped you and click "Accept as Solution" if your problem is solved.

According to the link posted, I am using BIOS

 

But it probably might be the pSu not supplying enough power.

Would that cause the whole system to not boot though?

If I were to purchase a new power supply, would that fix my problem?

Yes, if the system is not getting enough power it will not boot properly.  A new PSU should solve your problem.  I recommend at least 500W; 600W would even be better.  I like OCZ and Corsair PSU's.  They are high quality with a reasonable price.
