Hello,
I have Powercolor 5770 GFX card. Card is hardly 3.5 yrs old.
At starting of PC I am getting 1 long and 2 short beep from mobo. No display is coming. It was freezing during games for some days then tried with VGA cable instead of DVI cable and was working fine then for some days. Then suddenly no display.
Tried with internal graphics of mobo and it is working fine, be it with DVI cable or VGA cable. No issues in display.
But when attaching the graphics card in the PCIE slot and attaching the VGA cable to monitor it is beeping from mobo.
What could be the issue, motherboard or graphics card or the pcie slot or RAM?

Config:
Proc: AMD Phenom II X4 955
Ram: 1x4GB, 1x2GB
Motherboard: Gigabyte GA 880GM USB3 Rev 1.x (no bios update done ever)
Supply: Corsair VX 550W

Probably the card. Could be the power supply, or the slot, unlikely it's the RAM or something major with the motherboard since the system runs fine without the card. Plus you have had issues with the card before it died totally so that pretty much shows where the most likely problem is.

Thanks for your reply.
Powersupply VX550 has 2 PCIE power connector, I have used both and result is same. Is the only option is to test with other card or test the card in other machine?
Can I try to update bios? If it resolves the issue....

Best solution

For what you are seeing, I doubt a BIOS update will fix things. I mean you already listed that it was crashing, then one port died, then nothing works. You can update the BIOS anyway, but don't think it will do any good. The only way to fully rule out the card as bad is to try a known good card in the system and/or that bad card in another computer. From how you described the issue, it's 95% or more the video card.
