So, I was helping a friend upgrade his PC,
His old build was:
GIGABYTE ATX LGA1366 Intel X58 + ICH10R DDR3 PCI-Ex16 PCI-Ex8 PCI S-ATA PATA USB3.0 USB2.0 IEEE1394a GbE GA-X58A-UD3R REV2
CORSAIR DDR3 2000MHz 6GB 3x240 DIMM Unbuffered 8-9-8-24 DOMINATOR GT CMT6GX3M3A2000C8
Intel Core i7 Extreme i7-980X 3.33GHz 12M LGA1366 Gulftown BX80613I7980X
MSI ATI R5970-P2D2G
PSU is a Seasonic 700W 80+
We just installed 3 sticks of RAM, a H100 CPU cooler and a GTX690.
Now the PC doesn't post at all! When we turn it on, the fans start up, but nothing happens. The screen says signal, then entering power save.
There are no Beep codes, but lights on the motherboard do light up.
I then back tracked the new hardware and put it all back to it's original state and this behavior continues.
Does anyone have any ideas of what happened and what we can try?
