Win7 Blue screens Custom-built PC

Asus Rampage ii extreme motherboard
January 26, 2010 at 10:37:14
Specs: Windows 7, 2.66 GHz / 6GB
Ok. Now i am very angry. after my problems
before. I returned the faulty ram and
motherboard
(rampage extreme) and got a refund so
decided to go with some a little better so got
this new
(n) = new item (o) = had before

Asus rampage extreme 2 (n)
Intel core i7 920 (n)
6gb Corsaire ram(n)
sony dru-870s dvd drive (n)
HDD WD black 640gb (o) (but have tried
others so not the problem)
Nvidia 8800 GTS (o)

So the problem. well i keep getting blue
screen for no reason. they could happen hours
apart or just minuets apart. A stick of ram was
faulty and there was a fault on the MB so i
return them both and move to i7 system but
then after a few hours. I get a blue and was
was is it the same blue screen as before I
replaced all the hardware.

ok wait i think i got it with the bluescreen
viewer thing.
A problem has been detected and Windows
has been shut down to prevent damage
to your computer.
The problem seems to be caused by the
following file: ntoskrnl.exe
UNEXPECTED_KERNEL_MODE_TRAP
If this is the first time you've seen this stop
error screen,
restart your computer. If this screen appears
again, follow
these steps:
Check to make sure any new hardware or
software is properly installed.
If this is a new installation, ask your hardware
or software manufacturer
for any Windows updates you might need.
If problems continue, disable or remove any
newly installed hardware
or software. Disable BIOS memory options
such as caching or shadowing.
If you need to use safe mode to remove or
disable components, restart
your computer, press F8 to select Advanced
Startup Options, and then
select Safe Mode.

0x4a5bc600

Another thing i have tried all the following
things,
installing windows on different hard drives
different dvd drives
updating BIOS.
reset CMOS

something else I should say is when trying to
install windows It would keep freezing. The
way i sorted this was to in the BIOS set CPU
level up to 965 (3.2GHz). I pc won't boot when
set to auto it just freezes at "starting windows"

The only hardware i have not swapped is the
Graphics card as i don't have another one to
test with.

Please please please help.

Thanks

You know what I'm not seeing in that list (or even mentioned)? A PSU. Make sure it's not faulty, and make sure it's big enough.

Still test it. If it's surging, it could be causing damage to the MB, RAM, and CPU.

If the voltage is dropping too much, it could cause memory corruption.

While on the subject of voltage, check the BIOS settings for the RAM, and make sure it's within the specifications for the memory modules.

What does "SPD" mean

Also a little update found another GPU and still same
problem. I am very new to OC and the bios is extremely complex so any walkthough or recommended setting was be
very helpful.

THanks again

Read this.

What does "SPD" mean
The SPD is a little chip on the memory module that tells the BIOS about said memory module.

Hi. ok will order bits and give that a go.

A little more information:
If i boot in safe mode that stops the blue screens but not the
freezes. I have just reinstalled windows again (so there are no
asus drivers installed) and see if I get and blue screens running it
like that ( so far after 20 mins or so no blue screen).

Thanks again

"What does "SPD" mean"

SPD = Serial Presence Detect

As Razor2.3 explained, it's the info on a small chip on the memory module that tells the BIOS how to configure the RAM settings. If you have the memory setting on AUTO, this chip is where the settings will come from.

I recommend that you disable SPD & manually configure the RAM settings. DDR3 RAM is *supposed* to run at 1.5v but I see your's is spec'd out at 1.65v. If the board is defaulting to 1.5v, that might explain the BSOD.

BTW, have you tested the RAM with memtest86?

Hi. First about the psu. I sealed if for another one I had
(500w) but still had problem. Yes have have done all 3 sticks
and all pass. Will try the manual setting in the bios.

"Yes have have done all 3 sticks and all pass"

Not sure what that means...did you test them individually or all 3 at once? Ideally, you should do both.

First thing to check is to see if your RAM is on the QVL. Look at the link below to see.

Are you running a 32 bit or 64 bit version of Windows 7?

that error code tells me you are getting a double fault

A double fault occurs when an exception occurs while trying to call the handler for a prior exception. Normally, the two exceptions can be handled serially, however there are several exceptions that cannot be handled serially and in this situation the processor signals a double fault. The two primary causes for this are hardware and kernel stack overflows. Hardware problems are usually related to CPU, RAM, or bus. Kernel stack overflows are almost always caused by faulty kernel-mode drivers

so if you have swapped out the motherboard and the ram already my next stop would be looking at the cpu.


If either software or hardware can cause a particular trap, a debug is required to determine which is the cause. If you suspect a hardware problem, try the following hardware troubleshooting steps:
Test the RAM in the computer by running the diagnostic software that is provided by the computer manufacturer. Replace any RAM that is reported as bad. Also, make sure that all the RAM in the computer is the same speed.
Try removing or swapping out controllers, cards, or other peripherals.
Try a different motherboard on the computer.
If you are over clocking the speed of your processor, set it back to the speed at which it is designed to run.
Check with the hardware vendor for any updated hardware drivers or BIOS updates, or both

you have already done some of this. are there any other usb devices you are connecting? Also I have heard of the ntoskrnl.exe causing issues. Some have simply disabled it and it works fine with their system but I highly do not recommend it a reformat should have fixed the issues if it was software obviously. So like i said see if you can try a different cpu or test it.

see if anyone of those work for you and let me know.

hi no its not the CPU. I posted on the microsoft forum also
and they seem to think that is Norton 360 causing the
problem which is something i never concidered (the first thing
i did after the clean install was install norton) anyway I will try
out a clean install and not install norton.

Some extra info for post above
yes i have tried RAM that is on the QVL
its windows 7 64 bit

Thanks again

software would have been my next guess because the ntos kernel is related to networking and print sharing from the sources I found. One person found bittorrent to be the problem
no and copy and pasting info isn't stealing it is easier then giving him the link because i sorted out all the data that he needed. It may not be the cpu but really it isn't any different then suggesting he test his new ram that he just bought but since it is a hardware issue normaly from that error code best to check all hardware first and move on to software. In order to sort that out I would suggest nortons 360 first they are probably right. I have seen nortons 360 crap out alot of pc's if you remove it remeber to use the norton removal tool. Sometimes if you just uninstall it you get the result of getting no internet connection it is pretty commen.

innokenti: the ntos kernel is related to networking and print sharing from the sources I found.
The [Win]NT O[perating] S[ystem] Kernel does a lot more than just networking. It provides the basic abstractions all Windows applications are based on.

"copy and pasting info isn't stealing it is easier then giving him the link because i sorted out all the data that he needed"

But you didn't put the info in quotes, nor did you say, "I found this at Microsoft", nor did you include the link. So to me, you're trying to pass the info off as your own.

"It may not be the cpu but really it isn't any different then suggesting he test his new ram that he just bought"

You mean to tell me that you don't test brand new RAM? I do. And I believe most of the people with any experience in this forum know enough to test new RAM before putting it into service. I also recommend manually configuring the memory settings in the BIOS. The JEDEC standard specs out DDR3 RAM voltage at 1.5v, yet many RAM manufacturers ignore the spec. His RAM is supposed to run at 1.65v but the board *may* be defaulting to 1.5v. IMO, it's always best to manually configure the BIOS settings....all of them, not just the RAM.

hi. ok thanks for help I reinstalled windows (fresh hard drive)
and did not install anything and yeay no blue screens but now
i must about another problem which is just as bad or maybe
even worst (as it gives no error codes) as the blue screen.

The pc will just randomly freeze (in safe mode also) Im not
sure if this is a windows problem but will start from the
begining.

I i set my motherboard BIOS to default settings when which a
blank hard drive in, I then put in my Windows 7 install disk.

It gets to "starting windows" and will just freeze the solution to
this problem was I have to set using the auto OC feature in
the ASUS BIOS. I set my i7 2.66 GHz to run at a i7 265, 3.2
GHz. I then change memory speed and and voltage etc. It will
allow me to install windows 7.

Once installed if i then set BIOS back to default it again gets
to "starting windows" and freezes. So i set the BIOS back to
the OC and it starts fine. However the computer will randomly
freeze and i mean totally freeze, it does not respond to the
mouse or keyboard or Ctrl, Alt, Del, and other combos. The
only way to get out of this is to hit the power button on the
case. This most often happens when surfing the web or when
i try anything like Running the windows performance
evaluation tool.

I know its not any of the following hardware causing the
problem
Graphics card
PSU
hard drive
DVD drive
Screen
Keyboard
Mouse

This problem is in many ways worse than the BSOD because
it gives me no files or error codes to show you. This happens
without without the asus drivers.

Something else it is not because of temps (watercooled) CPU
never gets over about 40c ram also has its own cooler and so
does the chipset.

Please help as this is a major problem almost as big as the
BSOD.

Thanks again

You might want to check for Asus BIOS updates, especially if you can flash the BIOS from the BIOS menu. My MB had a major flaw in its RAM handling that was fixed by a later update.

Are you experienced at overclocking? This board is a tweaker's delight but you have to know what you're doing. You really shouldn't be overclocking until the OS is installed & running stably anyway.

Overclocking an i7 is different than overclocking any Intel CPU that preceded it. If you're just selecting one of the Asus overclock settings such as "i7-crazy-3.60GHz" & doing nothing else, that could the problem. You still have to adjust the other settings. As the following article states: "Upon first entering the BIOS, you'll be greeted with the overclocking section right away, which is something we've come to expect with their enthusiast boards. The very first option is interesting, though, as it allows quick access to either a 3.60GHz or 4.00GHz overclock. It will simply adjust the Base Clock and QPI voltage accordingly, but in my tests, neither was stable enough without making further adjustments"

Hi. no im very new to overclocking but when the board is set
to default settings I can't do any thing windows just freezes
when it gets to "starting windows". This happens if i try to
install windows as well. The only way to get past this problem
is to OC the board which i used the ASUS auto feature for.

If you have some recommended setting for the board please suggest.

Thanks

I don't run Vista & can't view .evtx files.

But I will say this one last time - you have to manually configure the RAM settings to the manufacturer's specs, especially the voltage.
