    Sick PC, multiple faults. Software or hardware?

    Hello and thanks for having me

    To cut a long story short my computer is now a brick, or potato etc etc

    It's stuck in a continuous blue screen death loop.

    I'm getting multiple fault messages, to name a few :

    Your PC ran into a problem and needs to restart"






    I didn't record them all as there seems to be a new one on each boot. I think at this stage that my motherboard is faulty, I hope I'm wrong and you guys can suggest something windows related. Here's what I've done :

    First step I took was to attempt to restore windows to a restore point before the last windows update (On 2nd March), before I can even select the date the machine brings up a fresh fault/blue screen, I can't proceed. (That's if I'm lucky enough to get as far as the recovery console)

    I started looking at hardware, as the case is small (Corsair 380t) and the GPU is in the way, I started there. Removed GPU and ran computer on the onboard graphics (Same issue) Removed and reseated ram (Same blue screens), tried individual sticks of ram in each slot (Same issue). Cleared CMOS by bridging the pins (Did not resolve the issue), removed battery wire and plugged back in. (It's clearing ok but still getting blue screen loop)

    I completely unplugged it's Samsung Evo SSD (This is where windows is installed) and I'm still getting blue screen loop?

    I've tried a fresh install of windows via the same method as the first install, via USB drive. Won't work, blue screen loop. Plugged in my USB DVD drive with a DVD copy of windows 8.1, the drive is picked up in the bios perfect but once the message to click any button to load/install windows appears, when I hit a button it fires me back to the Asus boot logo and then blue screen loop.

    Hopefully my spec's are viewable. The bios runs perfect, but the second I exit it it's blue screens all the way.

    Power supply is a EVGA Supernova 650 W Gs Gold 80+ Modular. Hopefully the rest of my spec comes up, if not I'll post after.

    Edit: To confirm, the PC ran perfectly for a few weeks without issue. There was no new software added around the time of problems arising. Also I can't get into windows at all, anything outside of the bios and I get blue screen on a loop.

    Many thanks in advance

    So many different BSODs are a general indicator of hardware related issue. You are suspecting the motherboard, and that possibility cannot be nullified. But, we cannot test a motherboard itself.

    Make it sure that the RAM is not causing the issue. Test your RAM modules for possible errors. 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.
    Take a camera snap of the memtest86+ window before closing the program. Let us see it.

    Excellent, thank you for the reply. Will try the memtest this-evening and update later :)

    6 Passes in and no errors, it's still running at home while I'm in work. I dropped Asus support an email and got a very quick reply, they recommend I return the board to the supplier for a replacement.

    I've had a few DOA's in my time but never a working board suddenly go faulty, especially without doing any tinkering to it :)

    Will keep you updated

    Best regards

    Just can't believe this, brand new board arrived, installed and same faults To say I'm gutted is an understatement. And now I know I've sent a perfectly good board back to Amazon (Or Asus) with zip all wrong with it.

    Pulled out the power supply, check connections etc. Not sure what else to try

    Whats left? CPU? Could I have a faulty 6700k?

    Done an online chat with Intel. They think very possible that it could be the CPU but that I shouldn't be running the ram at 2666mhz as this will possibly cause the CPU to fail? Said it should be set to 1866mhz.

    I hate sending anything back when I'm not 100% that it's at fault, but I guess I've no option

    Update :

    Made changes in the bios for the CPU to run on 1 Core and it now boots into windows perfect :) Ok now it's good to know that I have basically confirmed a faulty 6700k. Once replaced I'll be constantly waiting for it to happen again

    From Z170I PRO GAMING | Motherboards | ASUS Global

    * Hyper DIMM support is subject to the physical characteristics of individual CPUs.

    At the same time, Intel Coreā„¢ i7-6700K Processor (8M Cache, up to 4.20 GHz) Specifications says ....

    Your RAM is Crucial Ballistix Elite 16GB Kit (8GBx2) DDR4-2666 UDIMM, BLE2K8G4D26AFEA from I think?

    It seems that you should run the RAM at 2133 MHz.

    Thanks for the reply, yes that's the correct ram. I've now set it manually to 2133 MHz.

    Typing on the broken PC now, running away happily on 1 core :) I had the CPU packed up ready to be returned, but thought I might aswell boot her back up and have a look in the event viewer. I can't say I'm overly familiar with the event viewer, but I was expecting to see more errors. Perhaps all the BSOD's aren't being stored. I've a handful of Kernel-power 41 ( The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly) When I say handful, I've had 5 in the last 7 days. These are the only critical events.

    I've done a quick search and people with this code seem to be getting random reboots and system freezing etc, typical that I had none of that. The PC ran perfectly stable yet one day it decided not to boot and go into the BSOD loop.

    My power supply was bought at the same time as the CPU/Ram/board, it's the EVGA Supernova 650 W Gs Gold 80+. I could be wrong but I'll presume it's not the problem. A failed CPU is probably quite rare, and I hate sending back items that I can't be 100% sure are defective, but I guess I've not much choice

    New 6700k arriving Tuesday so we shall see :)

    A Kernel-power 41 is not a BSOD, it is an abnormal shutdown. Even if the electric switch is turned off, it will cause a Kernel-power 41. It may be, or may not be accompanied by a BSOD.
    Was there any Error level events in the event viewers? BSODs are recorded as error level.

    Get the replaced CPU, and then see how the computer runs with the changed RAM speed.
