help needed.

Hey guys im new to the forum. i have ran into a problem and its been doing my head in since Thursday. the setup up is an  ASUS Z97-P motherboard, i7 4790k, gtx 960, 2x8gb hyperx fury 1866mhz, kingston 240gb SSD and a corsair 500w psu on windows 7. i ran into a problem with pfn_list_corrupt when i had 2 ram modules in after initial setup but worked fine with only one module. so i ran memtest86 and it came back with faulty ram. so i got the ram replaced. when i receivedthe new ram i ran memtest86 for over 5hours with 0 errors. with the new ram i still had the blue screen. so i figured while i was installing the first time the ram had corrupted windows file so i tried to do a clean install. but after the first initial part of the new install the pc rebooted and got a blue screen again. so i removed  the second ram module and done a clean install. once windows booted up i ran another memtest on both ram sticks with no errors. i removed the second ram stick just incase and continued to install drivers from the motherboard cd. and installed all windows updates. after all the updates where done and all drivers upto to date. i then put the second stick in and booted up. i now boot up ok, but if i restart the pc i get a blue screen, restart and when i launch startup repair i get a blue screen, but when i choose start windows normally it boots up fine. i have also ran chkdsk on the SSD with no bad sectors showing up. i have exhausted all my knowledge with no avail. any and all help will be appreciated thanks!!

This error is linked to bad driver or faulty RAM.

Make sure your UEFI is setup properly, don't apply any overclock either. Make sure you set your RAM XMP (eXtreme Memory Profile) to Profile 1.

 

If everything is setup correctly, update your UEFI to the latest version. Refer to your motherboard manual for instructions.

 

Also did you install ANY software in your computer?

UEFI is what replaces BIOS. Your system doesn't have a BIOS.. it can emulate one, which it should be doing now if you setup your system properly by disabling UEFI, allowing the system to emulate the old legacy BIOS, for old OS, like Windows 7.

 

But yes, that is what I meant. So good.

 

Another test you can run, is Windows memory diagnostic.

In the start menu, just search for "Memory", and run it.

If you cant' access Windows, then you can boot from the Windows 7 disk, then select "Repair Windows" instead of Install, and you'll have the option.

ok im currently running memtest again on both ram sticks and 1 pass completed so far without errors. i have not overclocked anything as i havent even got the new system up and running yet to do anything to it yet. i understand that pfn refers to memory or ram but with memtest saying no ram faults, chkdsk coming back with no bad sectors on the SSD, and drivers are all updated is there anything else i can do? can there be a problem with the mobo dimm slots?

Could be, but then I am thinking that it should report the memory being faulty again. The next thing to look is drivers you installed.

should i uninstall each one and try a restart? if it still has blue screen reinstall that driver i just uninstalled from Asus website then to try a narrow down which driver it is? or will i have to install all drivers from the website all in one go then restart? at this moment im so tired and confused from this been at it all weekend lol

Did you try a fresh Windows installation, I mean like a copy of Windows directly from Microsoft's site? It sounds like a corrupt Windows ISO. Also sounds like a motherboard issue, did you try updating the BIOS? Have you also talked to the motherboard manufacturer?

yeah i updated the bios after the first initial install as i was looking it up online. never heard of a corrupt ISO but its something else to try, maybe its my optical driive? as it is out of the VERY old pc. Yes i have got onto the mobo seller they had said about the clean install of windows but this was on thursday and couldnt do it until after work friday night and they are closed all weekend. so while i was off im trying to get it sorted. basically i have to narrow everything down to show that it may be a mobo fault and get a replacement. i will be contacting them again tomorrow but im dying to get onto the rig to do some gaming so im trying everything i can to get it sorted. if the drivers fail i will try installing windows again with the external dvd drive as it is newer and used less to see if that makes a difference.

 

thanks for all the info so far guys i will be back tomorrow to say the results.

ok i just reinstalled all my drivers again with each time the pc rebooted i got a blue screen  so i removed the extra ram and done all driver updates. shut down and put the ram back in booted up no problem. but if i reset the pc i get a crash, then startup repair crashes. but if i skip the repair which is recommended it starts up no problem. shut down and started up 5 times in a row no problem. just getting problem with restarts. i will try IAmLamps suggestion with using a different optical drive and from the microsoft website too for clean install of windows tomorrow as its too late to do it now. wish me luck guys

i have ran memtest86 for overall added up and over 10 hours without faults. the RAM has been tested in my neighbours pc (same bundle) without issues. His ram (same ram) used in my pc with the same issue. i have done everything i can to narrow this down from isntall updated drivers, windows updates and updated the BIOS and it seems to me to be a motherboard or CPU issue as the components have all been tested to see if they have caused the issue. i have installed windows with either stick of ram no problem, but when both are in there is a problem. The GPU was removed from the system and windows reinstalled with the same issue. i used a media creation tool to make a windows install USB to exclude my optical drive and disc with the same issue. i have tried my storage HDD to ensure the problem did not lie within the SSD still had the same issue i have also removed my SSD from the hotswap bays and connected directly to the mother board via new SATA cables provided and the old ones i have to ensure it was not the hot swap circuit boards or cables. i have taken my SSD, RAM and windows disc into my neighbours and put it into his pc so effectively changed the motherboard and CPU and windows loaded onto the SSD with both ram sticks in the motherboard with no failure, i then went ahead and rebooted the system 7 times without error. So it seems to me i have done enough to ensure that this is a problem with the motherboard/CPU i have received.  Upon removal of the motherboard from my system i have noticed that the installed CPU cooler has its back plate covering the motherboard dimm pins on the back. this itself brings me concern. The PSU is from my previous working pc so can it be that?
