Thanks for the quick reply,
yes, I've loaded optimal default right after I flash the bios. I remember that the first time I started the computer after the update, it was freezing in the startup before I manage to enter the bios. the second time it was loaded ok and then I enter the bios and loaded the defaults. it was working fine for the following week and the start freezing again.
I'm running the MemTest right now and update with the results, but I don't think it's a memory issue, it's one week old. worth trying anyway
about the Raid, the 2 sata disks (320GB) aren't new, they are 4 years old but were never cause trouble before. also I checked on windows with the Intel Rapid Storage Technology and it was look healty. after the MemTest would finish running I'll try configure IDE instead of ACHA and see if it getting freeze on bios. I hope this is not the issue because the OS installed on this drive
My PSU is quite new, I bought it after reading the MB manual and they were recommended a 500v PSU and up. I also check with corsair website, they
have a compatability engine and they recommended a 430v and up. before I'm Throwing it away, I need to be sure this is the issue. is there any tools that can check this out?
I'll keep updating,
any more suggestions are welcome.
Thanks
