and another system error

[Big Booger]

Error code 1000007f = "UNEXPECTED_KERNEL_MODE_TRAP_M" - The first parameter displayed on the blue screen specifies the trap number. Trap number 0x00000000, or Divide by Zero Error, may indicate memory corruption. Other hardware problems, or software failures can cause this error. See the the link to Bug Check codes for more explanations about various trap numbers.

Check the memory, if it checks out fine, then go on to software and other hardware as the culprit.

Seems the error you posted above is quite common:
