All crashes caused by "ntoskrnl.exe." You should check your ram using Memtest.

Thanky you for your reply

Have loaded Memtest and completed the first pass in 25 minutes
with no errors
How many pass's should I do

rgds

Memtest now run for 2.6 hours and on its 7th pass
still no errors come up - How fool proof is Memtest ?

or do I just buy another stick of ram ?

On other bit of information is after each crash and the blue screen of death
it does a "dump of physical memory" and comes up with the following fault
"*** STOP: 0x0000008E (0xC0000005,0xF68FD81D,0xF4291A20,0x00000000)

does this indicate a memory problem ?

Memotest run for 3.5 hours with 7 pass' and no errors

3 mins of Windows then BSOD , msg on screen was

0x0000008E (OXC0000005, 0C804E7204, 0XF471A77C, 0X00000000

Attached also the last 2 minidumps
