[CSHIFT]

Hello everyone!

This my first post so go easy on me.

The Issue:
Client's computer crashes almost everyday.
Steps Taken:
Reinstalled RAM
Performed Windows Updates (hardware)
-Updated Ethernet Driver
Ran WinDbg on the Minidump Files
-The error that I found is:

*******************************************************************************

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: ffe3d420, memory referenced
Arg2: 0000001c, IRQL
Arg3: 00000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 80502e58, address which referenced memory

I would like to thank all of you in advance

I believe that this has been an issue ever since we put the computer together 1 month ago. I am not really sure what to do at this point, any input would be greatly appreciated.

Thank You

The dump log you've posted has crashed at IRQL 1c, and this is almost always hardware related. RAM tops the list followed by CPU. What's the RAM setup? Try running Memtest.

BugCheck 1000000A, {ffe3d420, 1c, 0, 80502e58} <-- IRQL 1c.
Probably caused by : memory_corruption ( nt!MmProbeAndLockPages+2da )

Thank You for the quick reply.

I will run memtest ASAP. However, I seriously doubt that it's the RAM because I replaced it 1 week ago.

Wow !!!

What a huge waste of time. The problem turned out to be that the case fan in front of the hard drives crapped out. In frustration I decided to replace the ram, and opened the case. Once I touched one of the hard drives by accident and got a blistering burn, I immediately knew where the problem was.
