Strange bootup problem

[pyramides]

I recently built a PC using these parts:
XFX ATI Radeon HD 4890 1024MB GDDR5 PCI-Express Graphics Card
4GB G.Skill RipJaws 1600MHz DDR3 Dual Channel Memory Kit
550W OCZ Fatal1ty Modular Power Supply
Gigabyte GA-P55-US3L motherboard
1TB Samsung SpinPoint F3 HD
BX80605I5750 - Intel Core i5 750, S 1156, Lynnfield, Quad Core
Xigmatek Midgard case
Arctic Cooling Freezer 7 Pro Quiet Intel CPU Cooler
Windows 7

Each morning I get various BSOD's, but if I remove 1 stick of ram the PC boots without a problem. I then can switch off put the memory back in, again the PC boots without a problem and will run perfectly well all day, restarting as often as I like.

I have run memtest86 on the individual modules of ram and on the 4Gg total and no errors found.

The BSOD's are varied in the error codes but I'm am leaning towards a hardware fault, but am open to any suggestions.

A PS, I have recently installed Bluescreen view and here are the last few BSOD's.

Are you running two 2GB memory modules? Can you swap the modules in their positions, like module 0 in slot 1 and module 1 in slot 0? How many memory slots are on the motherboard two or four?

 

[pyramides]

Yes I am running 2 x 2Gg modules, At the moment they are in slots 1 and 3 which are the correct slots.

 

[Tmagic650]

So swap the modules. 1 to 3 and 3 to 1... tell us what happens

 

[pyramides]

Will not be able to tell you untill tomorrow as it only occurs when I first boot up.
But I am sure that Ihave tried the modules the other way around.

 

[Tmagic650]

Okay,
G.skill is not the best memory around, but you could try and raise the memory voltage up a step or 2

 

[pyramides]

Could you explain in a little more detail as this is new to me.

 

[pyramides]

Looking at the blue screen viewerI have noticed that in the 11 BSOD's 6 of them involve 'ntkrnlpa.exe' which I have googled but not much help,except I was led back here.

 

[haribo2k9]

I think you might be using Windows 7 (32-bit), which only supports up to 3.5GB of RAM, try using the 64-bit version (if your processor supports it) or if it doesn't, just use less RAM.

Hope this helps.

EDIT: Have you reinstalled your operating system at all?

 

[pyramides]

I have reinstalled the O/S several times.

 

[Tmagic650]

Could you explain in a little more detail as this is new to me.

You raise the memory voltage from the bios. Just look carefully through the bios and change the memory voltage setting from AUTO to MANUAL. Now you will be able to change the memory voltage. Don't worry about the total memory installed. If you are running Windows 7 32-bit, the total system memory seen will be less than 4GB. If you are running Windows 7 64-bit, the total 4GB will be seen. This doesn't have anything to do with your BSOD's. Check your hard drive for errors. NTkrnlpa can point to hard drive corruption

 

[pyramides]

I have a copy of the ultimate boot disc and have run tests on the hd, nothing found.but will have a look at the voltage thing.
Oh and bye the way its NTkrn thats r n not m /lpa.
thanks.

"Oh and bye the way its NTkrn thats r n not m /lpa"..

Hard drive virtual memory or still a system memory problem
