Hard to troubleshoot..hmm
I will say try to change the battery first, just get the battery
that is the same type
THose battery that look like watch batteries shouldnt cost very
expensive, if your watch uses the same battery i think it is fine
to reuse them, as long as the type and voltages are the same
Anyway i thnk those batteries are cheap.
After you change the battery, i think the hanging should not
continue, as the info should be saved directly onto the mobo
instead of going to the ram, then back to the motherboard
again.
Faulty ram might cause hanging as well.
When your PC didnt detect the ram, it may be that the ram was of
higher speed than the one your motherboard can support, if the ram
is supported, than the slot is faulty.
O i see, the RAM slot was not upgraded at all. (I have 2 PC, one
is this mentioned, the other was spoilt for long time ago where I
kept my RAM as spares).
Out of the 4 sticks of RAMs (2 from each PC), 3 of them are
256MB. The remainder is 128MB. All 4 of them are DDR 400 and the
speed difference should be CL2(2.5) - 3(3.5).
PS: Not very sure the CL now, but the range should be within the
number without to within bracket.
