Had done a series of test recommended by Brianzion, but do not know how to analyze the datas. Do not know how to attached the results on this forum also. Had run the os on 2 different hdisk but same problem.

Its not likely to be the hard drive if you installed the OS on 2 different hard drives and came up with the same result. I have located your driver page on the MSI site- it has all compatible memory, bios updates etc - live update would be an excellent idea as it would update your bios - the manual is there also it may be worth studying so you could pick a incorrect bios setting to do with hard drives etc.

If the PC is too slow you could use the flash utility for the bios update and hope that fixes it -would be the safest under the circumstances - otherwise you might have an error and major problems

Hello Brianzion,
Attached is the result on the ram. It takes me an hour just to log in, post this reply ,hope it can let u analyze the result. THks all.

Hello,
Have not try boot into safe mode ,anyway the pc was install only with the win7 os 64bits with no other running software , anti virus. Have not install any driver also, the win7 os install all by itself. Any way thks all for the effort in solving my problem. Maybe will try updating the m/bd bios.
Thks

Your problem sounds like your MCH voltage is to low. Thats why it works fine with 2 sticks of ram vs 4. look in your bios and find out what your MCH voltage is. Try increasing it just a bit until it becomes stable. Dont go crazy with it Try 1.350 volts. Even though most boards support 4 sticks it does require some tweaking so the MCH gets enough voltage.
