I came to this conclusion that my psu is insufficient when i saw that whenever i use to run borderlands or cod6 or red faction guerilla like games with the highest settings @ 1280 res (i have a 17" lcd), after say 2/3 days the system would hang for no reason and would not boot giving 3 beeps error (which generally means memory error). But after several restarts and pluging in and out the power cable, the system would eventually bootup, then i tested the memory with memtest, and never found a single error. Now since the memory controller is inbuilt inside the i7 cpu, it has to be the psu. Since in a lot of websites i found out that a system with my config requires at least 650 watts psu which i don't want to buy now due to financial reasons. I would later do that eventually, but till then i want a patch up solution like what settings to disable in my system to run in low power ?
my psu is zebronics realwatts pro 600 with triple 12 volts rails.
and the temperatures are ok as seen with realtemp. I have hardly seen the 4 cores get over 60 degrees C and my 9800 gtx+ over 70 with full load running heavy games.
