my monitor works i have tested it

If you can hear windows sounds i'd assume windows is loading normally. No video sometimes means boot problems relating to memory or cpu but you're passed that. I suspect video cable or monitor, do look closer at either.

Ok so screen works with onboard. Gpu works in another pc. You've reattached gpu back to your own pc after testing and still nothing. Try clear cmos, remove the watch sized battery for a half a minute while pc is off. If still no go, good chance motherboard pcie 16x slot isn't working anymore.

try the graphics card of your friend´s system in yours

if the other card doesn´t work there too, try another power supply in yours

i have tryed a different gpu in my system and it works fine

What gpu did you try? Does it require the same power requirements? Nothing here is making sense so hope you're being honest.

try another power supply in your PC with the hd7770

the gt610 doesn´t need an extra power plug (only 30Watt), but the hd7770 does (80Watt)
which power supply are you using?

reset the motherboard by jumper CLRTC

BIOS is on version 1801?

replace the bios battery

did you use the DVI to VGA adapter with the GT610 too? Eventually the adapter is defective.

Its either the adapter or gpu.

Gpu works in a friends pc but not yours.

Tried another psu on your pc and no go.

Not sure if you've tried another video adapter.

Try the 7770 again in another PC. It's possible the capacitors on the gpu discharged enough during the visit and held on long enough for one last attempt. You brought the card home and it's dead, likely scenario. Or the gpu was damaged without realising to and from.

i have tryed my hd7770 on my dads pc and there it works i just checked

Using the same video port?

 

[helpstar]

Be sure the HD7770 sits tight in the slot, eventually plug it out and plug in a view times. I suspect your PCIe slot on the motherboard.

CMOS batteries (CR2032) are really cheap and when it comes to older hardware, everything is possible.

Connect your VGA cable to the motherboard while the 7770 is plugged in too. Get into windows and have a look at the device manager. Is your card recognized there?

Yes same video port

What monitor does your dad have and how/which video cable did you use to connect it?

I know you've said previously you use an dvi to vga adapter correct? It's been awhile, can you explain again how you have connected your monitor and and how you connect your dad's monitor.
