Faulty ram? Random restarts

[Isaque Luis]

Hey guys, in the past month, I've been getting a LOT of random system reboots, caused by I don't know what..

I've done lots of things, like, reformat windows, clean install, bought a new hdd, tested memory (with windows diagnostic tool - no errors tho), update drivers, unchecked "restart on system failure", cleared cmos, took of the board battery, unplugged everything then back on, tried using only the cables needed for the PC to start, cleaned and re-inserted new thermal paste, and maybe more things that I do not remember.

Specs:

Mb: ASUS M5A78L-M LE AMD760G (780L) SKAM3+

CPU: AMD FX 4100 4-core 3,6ghz

PSU: 1life:jet 600w

Ram: 1x CRUCIAL DDR3 4096MB 1333MHZ

Hdd: 1TB SAMSUNG HD103SI

Recently I've checked a program called prime95 to do a stress test on memory (I guess) and whenever I try it on "a lot of RAM tested" method, it doesn't even take 3 seconds for the system to restart...

Temps and voltages are okay too..
Any advices?

try clean your golden brigde memory with contact cleaner or at least with pencil eraser..

run memtest86 (http://www.memtest.org/) in dos mode, to check your memory error..

and jet 600w?
let's see..
+3.3V Amps 38 Amps
+5V Amps 44 Amps
+12V Amps 19 Amps
it's and old design generic psu!!

Generic psu always means low quality unit, fake wattage label, high ripple in all rail and other troublesome things..
dude, get a better psu !!

even corsair cx430 is 1000x better than this unit => http://pcpartpicker.com/part/corsair-power-supply-cx430
