Most of the crash were caused by iaStor.sys (Intel Storage driver) then you must update that driver.

It's also possible that your Windows infected by virus or rootkit.

Update these drivers:

iaStor.sys   Thu Jun 04 17:53:40 2009  → Intel Storage Driver

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 kernel debugger is available get stack backtrace.

Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, value 0 = read operation, 1 = write operation
