Kmode_exception_not_handled

memory 86+ did not find any errors. I wiped the pagefile last time you asked and here's the new blues screen

Code:

BugCheck 1A, {5003, fffff780c0000000, 6000000039f50, fffff980448c7c09}

Probably caused by : memory_corruption

Code:

Usual causes:  Device driver, memory, kernel

There is some memory issues or some driver corruption issues somewhere,

Code:

Run some hard-drive diagnostics and follow these steps:

• Hard Drive Diagnostic Procedure

Find your hard-drive manufacturer and run their tests.

Additional Tests:

• SeaTools for DOS | Seagate
• CrystalDiskInfo - Software - Crystal Dew World

Post a screenshot of Crystal Disk Info summary:

• Screenshots and Files - Upload and Post in Seven Forums

Make sure you have the latest firmware for SSD, and ensure all the SATA and Power cables are connected to the drive.

Check for any file system errors and bad sectors using Option #2 of:

• Disk Check

Use this command with Disk Check:

Code:

chkdsk C: /f /r

Hey, i ran western digital data lifeguard diagnostics with extended scan. Sadly it passed it cleanly... I'm doing the chkdsk after i post this update.

I had another bluescreen and i took a screenshot of the crystal disk info.

Volyme is clean... no surprises there...
I'm just about done with this carbage I'm getting new hardware from store. Any ideas which part should I replace first? Trying to do a budget upgrade here with as few component replacements as possible. Just a new compatible motherboard? New generation motherboard with a processor? New Power Supply Unit (PSU) with motherboard+processor? PSU+CPU+MoBo+new hard drive? new PSU+CPU+MoBo+HDD+DDRAM? new PSU+GPU+CPU+DDRAM+HDD+MoBo?

Save bet would be a whole new PC but that would be expensive + probably has some weak component + i love my PC case i have at the moment

I did power consumption test with my wattmeter extension cord. The PC draw around 350W during OCCT power supply test and i have 550W supply so it should be big enough? although if the supply is becoming old it will become unstable which can result into bluescreens.

Doing memtest 86 again and i let it run the next 20+ hours just to be sure i dont have faulty sticks

update: I bought new PSU and old generation motherboard that supports my other hardware. I installed them and doing bunch of tests or waiting for another blue screen

OCCT voltage graphs are looking good, during heavy load the voltage value deviates very little from the target voltage.

The crash seems to have an error:

Code:

12BB0, size 0x701000)
Invalid number of processors: 5439492

Please post back the results of the tests.

Been stable for one day and no sign of crashing here. Most likely solved, bad motherboard or power supply. I'm not sure but the voltages were jumping a bit and i could guess that if the voltage spike would be too high it could affect to all kind of things and crashing bluescreens. Here's a screencapture off OCCT power supply test Vcore voltages before and after the new hardware.

The new PSU does seem to have improved things, post back any other problems, hopefully you won't have any.
