Dell Xps 1645 four months of madness and nightmare, it is not what fails BSOD

Good afternoon, everyone.
First, I want to thank Dell, this fabulous laptop with three years I have been very happy, and I hope to continue to count on.

took four months without living.
I tried everything, absolutely everything, I will try to summarize briefly.
My 1645, has its own life and when you want it restarts.

Operating Systems:

The failure started with win 7, system manufactures.
I tested with win xp upgraded to stop.
And now with windows 8

Never mind. Always happens randomly.
Windows 8 is showing me something finer system events and possible causes.
Dell tool, my Dell, it is able to capture the error when a snapshot Blue.
APPCRASH, not recorded whenever this failing.
BlueScreenView, sometimes does not even know what happened.

Let's start:

What does the PC exactly, symptoms:

The pc reboots randomly.

Sometimes this happens a week without.

Other times, with cold Pc, when I start in the morning, after a few seconds it restarts.

Sometimes the screen goes blue but makes no reference to any driver or file.

Most of the time, just restarts.

On certain occasions, when you restart, the lights show error code:

mute: steady, volume down: light flashing, volume up: steady light

General State of the System:

According to Aida, all parameters are correct.

Temperature, voltages, etc. ...

According to Dell tool, My Dell, and self-diagnosis tool f12, everything is Ok.

Once after a reboot, the self-diagnosis tool remained locked in long memory test.

Reports of My Dell, I saw that once I put, new hardware removed, and puts me below, added new hardware (memory modules)

This has only happened once.

equivocal data

Some weeks I'm rendering with Cinema4D, for 6 hours, and all perfect.

Temperatures guarded.

Everything works perfectly.

Win 87 only takes 6 segudos me to start.

Other days, I get to see a client, turn on the PC, and BSOD.

A BSOD times the entire screen, other times, it looks small in the center of the screen.

There are days that I have open photoshop, after effect, cinema 4d, Flash Builder, and everything goes very fast and well.

Another day I'm on youtube, I'll watch a video and ... BSOD

My research and testing

The first thing I thought was that it was the ATI 4670.

Only once and under Windows 8

I gave the famous crash-sys-bsod atikmdag.

But never has recurred, I have the latest drivers.

This ruling gave it to me when installing windows win8 and propylene put a driver for the ATI.

I think it has nothing to do with me, it is not normal for me to spend a whole day working with cinema4d and nothing happens

First Step, test the memory:

With TESTMEM 4 from a clean boot, I made a memory testing with 9 passes from two possible states, Cold computer, and the computer after a long day at work.

The test told me that the memory was fine.

I contacted kingston, and sent me two specific modules for the XPS 1645.

Change modules.

BSOD, followed.

Probe, with a single module, with the two. Nothing ...

Second Step: The Hard Disk.

I tried several programs to see the hard drive health.

Mydell tool told me that everything was correct at the disk level.

Use from a boot disk smart Control, hDAT, HDSentinel ...

All they would tell me everything was fine.

Change the dissolution hard, with equivalent, completely new.

The BSOD have continued going

Third Step: Disable everything you do not use or want in Bios

When I tested with Ati in case it was the ati, lower aa Bios version A09 and the law in the forums that showed more stable with the ATi 4670.

After I saw it was not that, I went to update the BIOS to the latest version A13.

I have desactivate I do not want:

Wireless, bluetooth, card reader,

The blue screen continues.

Step Four: Test and force all drivers to see if drivers problem.

One day accessing safe mode win 7 stayed frozen.

I have no words ... in order ....

As he left the blue screen sometimes but I indicated that is what gave trouble, launch the driver verifier, which brings windows.

Was two days, without a single problem, and turn it off to keep working ...

Step Five: Could it be any virus?

tdsKiller + smart security + updated windows *** ...

not a virus ...

Tired, very tired of this

I'm really tired, very tired of this, and very unhappy.

For the first time in my life, I have a faulty PC and I can not find what it is.

I have no evidence to prove the computer motherboard, I tend to think it's the board.

And that sometimes it does not communicate well with system memory modules.

Appreciate a solution to the problem.

I can not go to customers, turn on the PC, and stay toasted the PC

Neither I nor DELL ....

Today I made a test, had not done before, to go discarding things.

When morning the PC was totally cold, the first thing I've done is press f12 at startup to get to the diagnostic menu and has reset only when I was doing the memory test.

Then when it was hot, a minute or so, it has been perfect.

What can it be? What is failing, that when the PC is cold restarts and when hot so good?

once in the memory diagnostic My Dell,

in "advanced test pattern" (to me out the first in memory) told me it was out of parameters, and it showed in orange.

Then I realized many times that test, and it has done well.

Now to remove the PC to see the part number and look for the motherboard in case. I've noticed that when you remove the battery current and the BIOS settings lost.
I have disabled the wireless in the bios, the external esata and some other things.
And I noticed that the event history for the system that captures diagnostic myDell tells me before the restart of the system that had found new hardware, memory chip, Firewire port, etc ...
(which had disabled in the BIOS)

Not output message that the CMOS battery this worn.
This could induce a reboot?

thank you very much

thanks

Having good afternoon.
