I just finished putting together my gaming pc. I boot it, enter the bios, and only 4 gb of RAM are recognized out of the 8 I installed. I tried the RAM in different slots, and only put one of each stick in. Each RAM stick is recognized. Also, when I get the "Insert Boot Device and Press a Key" screen, I put Windows 8.1 in, press a key, and nothing happens. My brother has the exact same pc as mine, and never had these problems. Here are pc specs:
MOBO: M5A97 LE R2.0
CASE: NZXT PHANTOM 410
CPU: AMD FX 6300
GPU: HIS ICEQ HD 7870 GHZ EDITION
PSU: XFX PRO550W
WIFI: TP LINK WN
HDD: SEAGATE BARRACUDA 1TB 7200RPM
DVD DRIVE: ASUS 16x DVD DRIVE
OS: WINDOWS 8.1 64 BIT
By the way, this is also after I got a repaired motherboard back from ASUS after the fan connectors werent working. They work fine now.
