Windows 7 BSOD during most newer video games

I've been getting repeated crashes on my l502x laptop whenever playing most video games, especially those that are a little more graphically intensive. Until recently I could play these no problem, but now after 15 minutes to an hour in the screen locks up, the sound turns into a drone, then I go to BSOD or in some cases the computer hard reboots. I recently ran a windows memory diagnostic and it came back clean and I reinstalled the video drivers, but it didn't help. Here's hoping the wizards on this forum can come up with a solution!

My laptop is an XPS L502x with an Intel i5-2410 cpu @2.30GHz
6.00 GB ram
64 bit operating system

Link Removed

Here is my W7F Diagnostic file with CPU-z screenshot and RAMMon.

Thanks for your time!
Majority of your crashdumps appear to be a sudden removal of the device associated with the Synaptic Touchpad driver, which probably means the touchpad itself. While usually this is normal behavior during a power down situation like putting the system to sleep or shutting down, the touchpad shouldn't be magically disappearing during normal use. I have a feeling this means either the motherboard or the keyboard/pad component is not doing so hot, which also means you'll need to turn the system in for repair/replacement if that's the case. I do notice the driver itself is old (Dec 17, 2010) so try updating it and see if that helps.

I also am noticing a couple of your most recent crashes being caused by what I believe to be a recent bug in the Nvidia drivers since the 310 driver series came out, which has been causing a number of people a lot of grief. If it persists, you may have success downgrading the driver before the 310 driver series. My current research into the situation has not turned up any more specifics on the issue, other than I am fairly confident it's a consistent problem.

If you wish for an improved assessment on the situation, you can turn on Link Removed as instructed here, making sure to restart the system afterwards. This will set Windows into a more alert state on detecting driver bugs, and if it finds one it will BSOD the system, which you can send us the crashdump for. As mentioned in the article, it may cause a boot loop, which means it's doing its job. Go into safe mode and disable Driver Verifier from there, then you can send us the crashdumps.


The spattering of crashdumps I looked at, starting with the oldest, has shown in a fairly consistent manner a power IRP for the Synaptic touchpad driver behind held up for a considerable amount of time. So far the ones I've checked have not shown that the IOStatus field for the IRP was populated with any error, so it doesn't appear to be a problem with the driver not understanding the power IRP given to it. I actually have a feeling it may have something more to do with the video card. So far whenever I dump the raw stack for the thread holding the IRP it has Nvidia drivers showing up all inside it. Updating the Nvidia driver didn't seem to fix the problem for the client, so there may actually be a hardware issue. It's possible the video card may be holding up the Synaptic touchpad IRP, but I cannot determine this by the minidumps. Using Driver Verifier will assist in providing us more clues.

Hi Vir Gnarus, thanks for the response.

My computer actually has a toggle to disable/enable the touchpad during normal use, which I use regularly. Could that be what is showing up in that section?

I'll turn on driver verifier later once I get off work and post the results for you.
I'm not sure, but that sounds like it could be it. Are you able to invoke a BSOD by turning it off? Understand that you'll have to wait around 10-15 minutes after the action in order for the BSOD to occur, if it does.
