hi i have an amd fx 6300 unlocked black edition core, with an asus m5a99x evo r2.0 with kingston hyperx blu 2x4gb ram running with a sapphire hd6750 gpu and a pulse power supply model pps-750br and a 1tb seagate sshd hybrid drive and my desktop keeps freezing under load or while watching a youtube video or even while booting and the freezes are completely random and happens doing anything i tought it was the psu so i changed it to a smaller 500w one and it helped for alittle while but now the its just the same and its really frustrating cause i cant use the computer for more than a minute on certain days but it helps when i turn down the frequency of the ram to 1333mhz and the volts to 1.4v it freezes between the 5-20 min mark and i am not over clocking my system everything is running on default, and the bios is at its latest and i also ran hirens boot cd tests on my cpu ram gpu and hard drive and it returned with no errors in either of my hardware and i have foramtted my harddrive many times and put various os's on it so it cant be related to software and i have tried my gpu on another desktop and it works fine and i have also put an ati firepro v3900 in my desktop but it still freezes, so any suggestions...
