قد تكون مشكلة في تعامل المدربورد مع الرام
when i got the pc it ran perfect until i tried to change my ddr3 to 1333 it would just lock up at windows load screen i would set it back to auto a nd it would boot fine
after some fiddle faddleing i found out what was wrong something with the bios mess's up when you lose total power clear the cmos and you can run at any freq you want
Has a very unstable memory controller. Boots sucessfully half the time. This is a common problem. Asus hasn't published any updates in the last 6 months and the issues persist. DDR2 1066 support is a joke.
