I have been trying to replace my current GPU for many hours....
==Current GPU
Sapphire Radeon HD 7770 GHZ 1 GB DDR5 HDMI/DVI-I/DP PCI-Express
== New GPU [ Christmas present from spouse ]
EVGA GeForce GTX 760 SC 4GB DisplayPort HDMI DVI-I/DVI-D Graphics Card with ACX Cooler 04G-P4-2768-K
== PSU is pretty new, has been driving things for a couple months:: Cooler Master Silent Pro M2 - 620W Power Supply with 80 PLUS Bronze Certification (other specs below).
I removed my old 7770 and drivers (control panel then Driver Fusion). Shut off computer, restarted without GPU, shut down, then put in GTX 760, inserted the 6 and 8 pin plugs from PSU, and restarted.
On starting I get a beep, and option to click del or F12 for BIOS or for boot menu. Keyboard press on del gets a click (or continuous clicking if I hold it down). F12 does nothing. After delay about 30 seconds, I get a second beep, same screen stays, for about 30 seconds more. Then I get black screen with cursor top left. I can get no response via keyboard or mouse at any time during all this.
I then replaced with my old 7770 and things work as expected (given removed usual drivers, but starts and usable etc...). Then tried the GTX 760 again. Same result.
I have been searching around. Possibilities could have been PSU, but +12V rail on this PSU is 50 amps and GTX 760 needs 30 amps. It has been driving the 7770 which needs ~7 amps I think. Not sure if I can measure the actual amps on that +12V rail or if that is a possible problem? Or it might be the new GTX 760 🙁 - it was mail ordered and has been under tree for a few weeks.
I don't have any other rigs to test the card in - thoughts?
Thanks for any help!
