I bought a 295 GTX point of view, installed it on a P5N32-E SLI with 4 GB DDR2 800MHz, Intel Q6600 and a 850W Thermaltake PSU.
At first I put the 295 on the PCIX No. 1. As result when I started the computer I got only the green light (no blue nor red). The fan didn't started
and nothing on the screen. Rest of hardware seems to run perfectly.
Then I tried it on the second PCIX. There, everything OK, the GPU runs correctly and I had great fun until I decided to buy the XFX 790I SLI ULTRA mobo
with 2x2GB DDR3 1333 MHz.
I installed everything and then, bingo, same problem as the first time. Only green light, when I start the computer the fan does not turn on (so I suppose the whole GPU isn't starting since there is no blue light). I tried it on the other 2 PCIX and it still don't work, I tried every combination of pins, the two PCIE directly from the PSU, the other two
extensible, one of each, etc. Still nothing. I tried the GPU on an other computer and it works perfectly. I tried with only one memory module and another PSU and nothing.
Still black screen and no fan spin with only green light. I tried an 8800 GTS I had, the fan of this one start spinning so I suppose its OK but I still got the black screen, not
even the "no signal" message on monitor, it just do nothing.
I really don't know what it could be, please, if you got any idea help me, I'm soooooooooo stressed.Thanks
