BSOD during idle, error code 1E

Hi dakoslug.

Dont use a BETA display driver.

Uninstall the installed display driver using DDU. Then install the CCC 14.4 WHQL only.

Let us know for any further BSOD after doing it. Because, some more steps may be needed depending on the resulting situation.

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault).  The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
        use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
        use .trap on that value
Else
        .trap on the appropriate frame will show where the trap was taken
        (on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
Arg2: 0000000080050033

If there are BSODs even after removing the ATI card, uninstall ESET.

Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Also, there is failure from the part of intel HD graphics.

As random things are crashing, it would be better to Test your RAM modules for possible errors.

How to Test and Diagnose RAM Issues with Memtest86+

Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If memtest86+ is free from errors, we will try to concentrate on the intel graphics failure.

OK, test the RAM first.

The sound during startup comes from the HDDs sometimes, when the start spinning.

Sorry for the late reply. I have some time today so I'll be running the memtest right now.

Edit: 3 pass, 0 errors.

Ok I let it run through 4 passes, and still no error. I know you told me to wait atleast until 8 so I will do it again overnight but it ran for almost 5 hours and no errors.

Do you still suspect that it might be a ram issue? Or should I continue with your other advice?

How are you testing the RAM? Are you typing those from another computer?
