Re: New GTX 295 Owner. HELP!!!
Exact same thing happened to earlier this week. No overclocking, just powered on my computer Wednesday morning and it would not post. Only difference is I am using XPPro on that machine. Popped in my old card - 8800GTX worked fine. I flashed the motherboard bios, reset CMOS, still nothing with the GTX295.
Ended up having to obtain a rma, (easy enough at evga.com). I paid $30 for "Advanced RMA", they crossed shipped my new card and shipped it next day air. The replacement just arrived about an hour ago, getting ready to run the benchmarks - again.
