I replaced a gtx650 by a 770, a 300W generic psu for a 600w evga 600b and the case too (NZXT H230).

With the GTX 770: All the fans are spinning correctly (cpu, gpu, case), I can feel the hdd with win7 spinning, as the dvd. The display connected by the new gpu (HDMI) is stuck on a page showing my specs and says ESC to start up menu but when pressing escape, nothing happens.
Yes, the keyboard is connected and was used to access the page with all the specs (probably shown by the Angelica OEM mobo). I can go back on the hp blue page with Ctrl Shift Del.

With the GTX 650: everything fine.

Why?

Thank you for your fast help.

That sounds quite likely. I thought the new cards were supposed to default to Legacy mode, but I have heard of motherboards not working with UEFI cards before.

I don't think Windows 8 would help since you seem to have issues before even booting into Windows. Plus, with a non-UEFI motherboard even if you installed W8 it would just install in Legacy mode anyway.

Unfortunately, it sounds like your motherboard won't work with that...

There's likely no issue with compatibility between the motherboard and power supply. The PSU just needs to supply the proper Wattage in tolerance so likely not an issue unless it is defective.

Troubleshooting:
1) Put the GTX650 back in to see if it works. If it does, the GTX770 might be defective.

2) Reinsert all the power cables.

3) Run MEMTEST www.memtest.org (if possible)

That's a bit of a weird issue though since it's almost working. I suspect it's an issue with the POWER SUPPLY. Not compatibility, but perhaps it's defective.

Works fine with the 650. Why?
But the fans of the 770 worked fine and it could display an image.

UPDATE: They will replace the card, might be defective, if not I really dont know what the heck. Still seems weird to me a gpu transmitting an image through the card, detecting the 8 and 6 pins connectors, the fans spinning not working inside...

After RMA the 770, nothing different.

Personally not being knowledgeable in BIOS and thingies, a guy told me it could be the HP OEM motherboard not accepting the UEFI of the GPU, since this motherboard wasn't really designed with this in mind and they didn't update it since 2 years.

What do you think?

*Try contacting the card manufacturer's Tech Support and see if they have a recommendation for this. Swap for a different card? Is there an alternate BIOS that the card could be flashed to in a working system?
