Specs: Windows 7 Home Premium, I7 720qm/ 8GB Ram
Hello, this is my first post Ever, I'll describe the problem as much as possible:

Alienware M15x, Intel i7 720 qm, 1GB Nvidia 260 GTX, 8GB ram, 500GB HDD

I'll start with this, I got my laptop before like 2 weeks, it was awesome, but it suddenly started to give me blue screen of death all from sudden, I use Kaspersky Pure, and seems like after I used Alienrespawn (Recovery for the laptop) the blue screen doesn't show up anymore, now I only have my laptop restarts suddenly, it's not overheating, I don't usually play games, I rarely do, anyway I think it's something to do with the internet connection, after watching tons of videos on any website, I use usb device to connect to the net, and wow once the device stops working the laptop restarts, that's 1

another thing is why I don't think it has something to do with the video card is that when I play crysis for hours my laptop seems to be fine and no restart and no BSOD

I even know an exact point where I get the Blue Screen Of Death, when I share connection with the Playstation 3 (LAN) I'm going to test the shared network on the PS3 it shows me that obtain IP succeed, network connection succeed ( on PS3 I'm talking) but either once It tests the NAT type or once it's done testing (NAT type is the last test that's why it's hard to tell) I DIRECTLY have a Blue Screen Of Death, I did that like 3-5 times and same results occure

any help or suggestions ? I have a 3 years warranty but I don't plan to use the warranty, I prefer to do my things as long as I can, and I can't wait for 1 week till they give me my laptop back and I realize that they still didn't fix the problem

thank you in advance !!

EDIT: oh by the way I used to use the same USB network device on HP530 Laptop, and it didn't have any problem

How To Disable the Automatic Restart on System Failure in Windows 7

After you have done that, if a blue screen appears it will stay on the screen rather than the computer Restarting.

Copy down the things that are unique in the message and post them here.


STOP: 0Xx00000xx (we don't need the stuff in brackets beside that)


There may be a problem file named at the end of the text.

There may be a link to More info or similar - if so, click on it to see if it names a problem file.

There may be a mention of a MINIDUMP file having been made - if so, copy down the name and location of it - you may need to click on a link to find that. That MINIDUMP file can be analyzed.

"I still have a sudden restart, but no BSOD"

That's not good.
That probably indicates you have a hardware problem,and your laptop may be defective or damaged.

Have you, or is it possible anyone else has....
- dropped this computer, or dropped anything on it, or subjected it to a physical jolt otherwise ?
- spilled liquid on it, or exposed it to liquid such as rain, or sprayed it with liquid ?

Has there been a power failure event while the computer was plugged into the AC adapter ?
A nearby lightning strike ?

If the answers to any of those are YES, then your warranty probably doesn't cover damage caused by that, unless you have already purchased additional warranty coverage that covers accidental damage.

If you are SURE the answers to all of those are NO, then if you just got this new a short while ago, you should be able to get the problem fixed free under warranty, possibly by a local repair place.

One last thing to try.....

A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.

For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.

I might help with 1 last thing of investigation before I call customer service hope you can help

I have Nvidia 260 GTX how much Vram does this have ? when I got to adapter on display settings it says : total graphics memory is about 4GB and the dedicated is about 1GB, system video memroy is 0MB and shared system memory is like 3.5GB I don't know exactly if this is about the vram or not, sorry I'm not expert at these things, actually I just learned all these stuff, and when I go to dxdiag and go to display it says approx total memory is about 494MB and also when I got to and test my laptop if it's possible to run a game, it says 494MB too can the Nvidia 260GTX be damaged ? or what exactly ?

thank you in advance !

Oh and the answer is no, I got the laptop before like a week and all "where it is" is sitting on the Desk, I don't carry my laptops I just put my laptops in my room on the desk, and never spilled a liquid on it cause I don't eat or drink while using my laptop, failure event ? I don't understand that, no for the last 1 about lighning, we don't have lighting strikes in my region, at least never heard of it happens here, and about my post above, it's Nvidia 260 GTX which as I remember seller said it's 1GB sized

thank you in advance !

"as I remember seller said it's 1GB sized"

So you bought it used.

In that case you have no way of knowing whether it's been abused.

Apparently the DELL Alienware M15x series is still being sold, but it first came out in October 2009, so your laptop could be as old as that.

"The Most Powerful 15-Inch Gaming Laptop in the Universe"

Released on 10/15/2009

Apparently this series seems to have an actual video CARD that can be installed and removed, rather than a video adapter built into the mboard like most laptops have that cannot be installed or removed.

There are three choices of video CARD it can have - two are ATI, the other is NVidia GTX 260.

* 1024 (MB) ATI HD5730 Mobility RadeonTM
* 1024 (MB) ATI HD5850 Mobility RadeonTM
* 1024 (MB) NVIDIA® GTX260M GeForce

All have 1,024mb (1gb) of video ram. That ram is NOT shared with the ram installed in the mboard, which in your case is 4gb (4,096mb).

"when I go to dxdiag and go to display it says approx total memory is about 494MB..."

If you mean when you click on the Display tab, when you run dxdiag, it says Approximate total memory: 494mb........

I'm not sure what that figure is for or what it should be. On a laptop that may vary, depending on what you're doing at the time. E.g when you don't need as much, the video chipset uses less memory.
That figure may vary depending on which video chipset you're using, on any computer, depending on what you're doing at the time.

To give you an example, I have a Radeon 3650 video chipset on a PCI-E X16 video card on my desktop computer.
Going to the same place - run dxdiag, click on the Display tab - in Vista, which has many things that are identical to the same thing in Windows 7
I see
Approximate total memory: 1784mb

The Radeon 3650 card has 512mb of video ram on it

There is 3gb of ram in the mboard.

The place where you can see how much physical video ram a video card has on it in Windows is System Information.

One way to get there is....

Click on the Windows 7 icon lower left bottom of your main desktop screen.
type: msinfo32 in the Start Search box, press Enter.

On the left side open up Components - click on Display

beside the Adapter Ram line is the physical ram on the video card.

In your case it's 1gb = 1,024mb (1,073,741,824 bytes)

""Has there been a power failure event while the computer was plugged into the AC adapter ?""

"failure event ? I don't understand that,"

As in, the power went off, or a circuit breaker on the circuit the AC adapter was plugged into was tripped off, or there was a power surge or spike - you may have noticed lights briefly being brighter.

"no for the last 1 about lighning, we don't have lighting strikes in my region, at least never heard of it happens here,"

Lightning strikes happen everywhere in the world when the temperature gets warm enough and there is enough moisture in the air for that to happen, whether you were aware of that or not. Unless you live in a desert where it never rains or in the Arctic or Antarctic, lighting does happen in your area.

What I mean is were you aware of there being an event where lightning struck the ground or a building or whatever in your area. Even lightning striking the electrical power grid a long way away can damage your computer when the AC adapter is plugged in.

If you haven't already done so, try cleaning the contacts on the ram and re-seating it.

If you are using any settings in the bios to overclock the cpu or anything else, that COULD cause your problem. In that case if you load bios defaults in the bios the problem should go away.

"it's not overheating,"

How do you know that ?
How hot does it get ?

The current CPU temp is show in the bios Setup.
You may or may not also have a program in Windows that shows you the same things the bios does - the current CPU temp, other temps, fan speeds, voltages.

"and all "where it is" is sitting on the Desk, I don't carry my laptops I just put my laptops in my room on the desk,"

Then why did you buy a laptop ?
You buy a laptop if you need a portable computer and intend to use it in more than one location.

If you don't need a portable computer, then don't buy a laptop.

You always get a better bang for the same money if you buy a desktop computer.

Nice detailed answer, seems like the only way to go is the warranty, but if you have the time you can reply to me to these questions as additional info for me to keep it in my mind I thank you for your time

I even don't know where to start, I'll break the thread to
answer well:

about me buying it used, I didn't know that companies sell used Laptops, and it has 3 years warranty, and how much does it have to contain ? it said 1GB Nvidia 260GTX

you mean I can upgrade the video card ? at least I can pick between those 3 you mentioned ?

wait it's 1GB that's not shared with the motherboard, and in my case it's 4GB, I don't understand this, I thought it's 1GB, can you explain it more, please ?

about the dxdiag, yes it's when I go to display tab it says 494mb, I clicked on that while I'm on the firefox browser for like 2 hours

about your video chipset, so there are actually 2 rams 1 with the video card and the other 1 is on the motherboard and the 1 on the motherboard shares it's space with the video card ? to give more space ?

about the msinfo32, display adapter says exactly as you mentioned "1.00 gb (1,073,741,824 bytes)

about the power failure, it didn't happen cause I usually have more than 1 device connected to the electricity wall, and non of them turned off or something, and I use a power converter with the ac adapter thought that helps in case I had power failure and the laptop runs on rechargeable battery

about the lighting strikes, I got my laptop before like 1 week and it didn't rain yet

I read about ram contacts yesterday but thought I have to avoid messing with that, I'll do it once I post this answer, about the CPU in the bios, I never entered the bios yet I also respawned the laptop before like 3 days or less, and I'll learn how to run bios on default settings and see if I still have the problem, hope so

as I'm typing this answer, there is the gadget option shows you the CPU usage, it's 02% goes to 00% ram usage is like 22% I turned the laptop on before like 35 minute and never did anything beside typing in this site

that's a nice and funny answer, yes I have a desktop and I bought this M15x because of the Alien lighting and I wanted this laptop before like 3 years, I do carry my laptops like once a week in case I have something to do, but I'm always worried about any damage

"...seems like the only way to go is the warranty...."

Usually you can only claim on the warranty if you are the original owner. Even if you can claim on it, accidental damage or damage caused by abuse is usually not covered by the original warranty, and you have no way of knowing whether that was the case for your laptop when the original owner owned it.

A used desktop computer is usually a good buy. A used laptop is much more likely to have problems.

"you mean I can upgrade the video card ? at least I can pick between those 3 you mentioned ?"

You may be able to order either one of the two ATI cards from Dell - I don't know. The third one is the one you have.
That said, those are probably the ONLY other video cards you can install.
I haven't looked on the web to see how a Radeon 5850 compares in performance to a GTX260 but I suspect the 5850 performs better.

In the case of this laptop, the 1gb of video ram is separate from the 4gb of ram in the mboard. The 1gb of video ram on the card is used only by the video chipset on the card.

The usual situation with a laptop is the video chipset is built into the mboard and has no ram of it's own - it uses part of the ram installed in the mboard - shares it - the portion the video uses cannot be used for other data by the operating system.

The ram installed in the mboard always has a much better max data transfer rate - up to about twice as much - when you use a video card rather than onboard video.

"just ran dxdiag and went to display tab it says approx total memory is 4077mb"

As I said above, I have no idea what that figure is for or what it should be. Obviously it varies depending on when you run dxdiag.

hi blue screen of death is normally related to bad memory modules there is a program called "hirens" can be downloaded its a boot disc that will test any computers hard wear, indiidually, if you need help locating software and using it contact me. lso over heating causes laptops to crash or freeze, anything that generates heat attracts dust on laptops it builds up on the cpu cooling fan area it can be blown out with air but usually meanns taking apart and cleaning to remove blanket of dust fluff. hope this helps
