Windows 7: ntkrnlpa.exe BSOD Windows 7

MS Windows 7 Ultimate 32-bit SP1
ntkrnlpa.exe BSOD Windows 7

Hi Guys

I really hope some kind genius can help me out here because I am running out of options.

I built a new PC initially I failed to connect the little 4 block on the PSU which I honestly thought was the cause of my problems hence my original post in this thread, but surprisingly this was not the case....

I get occasional system lockup/freezes and a BSOD the computer will just reset itself and very occasionally it will even lock itself up in BIOS or on the windows startup logo.

ALL my drivers are verified. I have no rogue software / malware. Tried 3 clean installs of windows 7 32 bit and still happens.

Memtest has been run for 72 hours with no errors, drive scan picks up no errors and I've even run the Western Digital drive scan again no errors.

I have updated my system spec to my profile, however I have since replaced my PSU and Graphics card. I am still having the BSODs so can discount those 2 at least.

I have the latest BIOS installed.

I have tried reseating RAM, CPU, GFX card etc. Sometimes system can be on for 3 days with no issues but then all of a sudden resets with a BSOD.

Last one did say "Memory Management"

I've uploaded a memory dump file of the latest error.

Given the fact that it has locked up in BIOS would make me think it must be hardware related but the shop has tested board and RAM for 3 days reporting no errors.

CPU is definitely compatible with the board. Temperatures range from 19 degrees to 45 degrees on CPU and it has reset straight after being booted up when the CPU is at it's coolest.

I can discount GFX card, PSU and Optical Drive as first 2 replaced and still happens and still happens with Optical Drive disconnected.

The only 2 things not brand new are Western Digital Sata Hard drive and Edimax PCI Wireless router card, but I have updated with the latest verified drivers, and it worked for 5 years on Windows 32bit with my old machine with no issues.

Any ideas??????

Thanks in advance!

Hopefully everything is in this post that you need to Debug my problem, my spec is below and I've attached the reports you recommend - Thanks in advance

Oh and I'd like to add that it still happens in safemode, I've tried 3 different VIRUS programs, AVG Avira and Panda, but never 2 simultaneously and I'm just using windows firewall

MS Windows 7 Ultimate 32-bit SP1

It seems to be now when I first boot up it resets straight after windows has loaded got a blue screen but nothing in memory dumps this time. I then cannot get it to boot successfully till I have fully powered it down and then switch it back on. Once it's on after that it can be stable for days???

Can anyone help? Or at least point me in the right direction? I have another hard drive that I can test and I can try running it on ethernet to rule out the wireless PCI card, but aside from that if it's board CPU or memory then what else can I check???

If ram runs ok on a memtest for 72 hours than what on earth could it be can anybody help????

MS Windows 7 Ultimate 32-bit SP1

OK now I got some more things popping up, funny thing is once it's booted properly it can be stable for days.... I have removed 1 stick of RAM and will try and see if it crashes again, if it does I'll switch the sticks, if it still crashes could I be unlucky enough to have 2 faulty sticks of RAM? Got to be very remote chance? I'll then try a diff hard drive with a clean install and if still does it then it has to be CPU/MOBO related.

One more thing I could try is CMOS battery but this is a pretty new board

The problems got progressively worse. It wouldn't always boot up with the optical drive connected it would hang and keep making a noise like it was trying to read a DVD. Then sometimes I wouldn't get a video signal. Then even it did reboot it would get to windows and reset.

I don't want to cross my fingers but I've just replaced the CMOS battery and it seemed to be a hell of a lot more stable and it booted up first time and quicker too.... Could it be too good to be true that this is my only problem??? We'll see

OK it wasn't the CMOS battery, doing weird things now it will power on but freezes almost straight away at desktop. I can no longer power it off with the switch at the back of the psu??? WTF! Have to hold button in at front for more than 3 seconds.

I am taking back to the place I bought all the parts from today and they are going to test it! It has to be hardware related. If I ever get a good outcome I will post here.

You can mark this one as solved.

I am owning up to my stupidity incase anyone else does something this daft and it helps them.

I bought a new case that had raised mounds in to screw the motherboard in without the need for spacers. I did not realise and screwed spacers into the raised mounds! So I'd double up the spacers in effect. This meant that the motherboard was too high and was touching the chassis causing it to short!

I would have never figured this out myself in a million years, one of the girls at the comuter shop I bought it from noticed! I could have kissed her!

That is all!
