Hello all, I find my computer crashing when I do certain things. First, when using dvd-rebuilder, and I now find the same error message (0x0000000A, plus the same "arguments")when I tried playing a few games ( such as rome: total war). IRQL_NOT_LESS_OR_EQUAL (a) An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses. If a kernel debugger is available get the stack backtrace. Arguments: Arg1: d78a6eb0, memory referenced Arg2: 00000002, IRQL Arg3: 00000001, value 0 = read operation, 1 = write operation Arg4: 804ff1c3, address which referenced memory I do not know how to interpret the error dumps and need some help. I looked at the msft site, but had a hard time understanding everything.Here are some system specs.

These errors do not happen in normal usage, or with other disk heavy activities such as torrenting or newsgroups.
