bugchecks bugging me: help!!!!!!

I am getting constant spontaneous reboots, all with more or less the
following message:

The bugcheck was: 0x 1000008e (0x8000003. 0x86ea01c. 0xb9f98b98.
0x00000000)
Another: 0x100007f (0x0000000d. 0x00000000. 0x00000000. 0x00000000)

They all follow similar pattern although no two are the same.

The machine can go two days or three without a problem and then bingo:
every couple of hours.

The system: (not overclocked; problems with memory at "auto" or per
Corsair specs)

Corsair TWINX1024-3200XLPT (2x512)
Amd x2 3800+
Asus a8n sli premium (bios: 1009)
Gigabyte 6800 gs
Pc Power and Cooling 510 sli

Plextor DVD
2 samsung 125 pata
1 maxtor 250 sata

CPU 30 -35 degrees
MB: 29 - 32
PSU: dead on

Latest drivers (nvidia video; nvidia chipset: 6.70. . . .)

Am I right to suspect the memory? Or the CPU (memory controller is on
the CPU)?

Any suggestions?
