Ihave examined the memory and disk for defects and found none.
How and when?
Well,
for the disks, i run the BIOS primary & secondary HD short & long tests about 30 minutes ago with no issues.
I also have regularly run defragler or diskeeper for maintenance and they never found any problems.
Chkdsk, also found no problems.
For the memory, i run the BIOS memory test awhile ago
I also run memtest86 a few days ago with no issues
BUT.........the good news is that i get freezes even while inside the BIOS menu. That narrows down the nature of the problem i think...
