ive recently given a mate to an am2 board (abit nf-m2sv) its got 2 sticks of 2gb ddr800, the problem is, when it gets to the windows logo loading (win 7) it shuts off or restarts. i have tried taking out the battery to reset things but to no avail. the psu is from a working system so no problems there, the cpu in athlon 64 x2 4400. any ideas guys.
