DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
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.
Arguments:
Arg1: 0000000000000000, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, value 0 = read operation, 1 = write operation
Arg4: fffff8800193b0d2, address which referenced memory

Try in Dell's site too?

Update to that driver is not the most feasible solution for this issue, because it will fail again after 6 months or so. But the other way involves a good lot of workload.

If Dell also does not have any update, we have to take that laborious way.

Neither.

Now let us come to the point. The failing driver is the RAID driver as stated earlier. And RAID is always problematic, I said about it in post #4 a little.

Now, as we cannot update the driver, better to break RAID right now. How to Disable RAID: 5 Steps (with Pictures) - wikiHow

BUT, breaking RAID will not allow you to boot into windows anymore. So you need to perform a clean reinstall. Clean Reinstall - Factory OEM Windows 7

So the plan is ....

1. BACK up your user data externally, or with cloud.
2. Break RAID
3. Perform a clean reinstall.

Permanent solution of this issue.

would it fix the problem if i chose a restore point from when i got the PC?

Nope!

still trying to get things backed up, having issues getting the Ntuser.dat files, not wanting to be copied. il get back to you when ive completed your instructions.

You need to copy the user files (documents, pictures, music, videos), not the user profiles. :)
