graphic card not working

[edwinclement08]

my system configurations:
amd fx - 8120 @ 2800.1 MHz
GA-880GM-USB3
Ram is corsair vengeance 4gb but only 2.8 is accessible because os is 32 bit
AMD Radeon HD 5770 Series
hitachi 1 tb harddrive

The system worked rather well for around a year. Now the grahic card does not work,at all.
At the moment I have Physically disconnected the card's power supply and use the on-board card, HD 4250
Most of the games work in this way but have to played at low settings. Whenever I reconnect that all I get as video is a blank screen, not even a response. I mean even the BIOS doesn't show up on screen.

Please help

is the card turning on where you can see the fans moving or is it just dead?

 

[edwinclement08]

The Fns move if the 6-pin power supply is connected

Things to look at open your case see if the power adapters are plugged into your card. Are the fans or fan moving on the card if not the card may be toast .Can you remove the card and test on another system?
Was you or have you experiance any BSOD or glitches related to the card before this all happen?

 

[edwinclement08]

I recently removed the adapter because if the card is powered the system stops outputing the video.
now only the pci is connected.
fans on the card are rotating at a rather high speed whwn turned on and emit a lot of noise
no glitches, nothing
not overclocked or any similar enhancement.
I will try to do so on another system as soon as possible
no, I dont think it's dead.

Also, let me tell you, I am a16 yr old, I have to go to classes in about 10mins so I cant reply to any of your hopefully helpful comments.
I just didn't expect the answers so quickly.Thank you so much for replying quickly.I am going offline. thank you

P.S. I am not a native english speaker , so please forgive my mistakes.

disable onboard graphics via device manager

 

[johnnyb105]

If your card has a power adapter it must be plug in as said above disable your onboard gpu or igu in the bios/

 

[edwinclement08]

Done the integrated graphics disabling thing. Set it to PCI Graphics

 

[johnnyb105]

is your card a pci card or pci express or the 1.0 2.0 ect ect

If you had, or have, the card in the system without the power adapter in it, you are just doing more damage to the card. It's probably dead now for sure if it was not before. Never run a video card needing external power without it connected. If you need to not use the card, remove it from the case.

I recently removed the adapter because if the card is powered the system stops outputing the video.
now only the pci is connected.
fans on the card are rotating at a rather high speed whwn turned on and emit a lot of noise
no glitches, nothing
not overclocked or any similar enhancement.
