I just want to confirm if it is possible to get the y400 650 ultrabay and sli it with the y410p 750 since I am guessing that I won't see this near in the near future.

Yeap, I hear the strange noises too indicating the display driver is unstable and that's the same thing I do myself to avoid a BSOD. It's quite a relief to know that its not a laptop defect of some kind. Regarding your question, I can't remember making any major changes (other than updating Nvidia drivers) recently that would cause something like this to happen. That's why it made sense to narrow it down as a BIOS issue. Now that you mention about your other rig having the same problem, I'm sure the modded BIOS is not the issue here. The strange thing is Nvidia's latest drivers claim to be optimized for these two games specifically. Ironic. Hope it gets resolved soon. Thanks a lot for your helpful reply. Do make a post if you manage to solve this.

Well to be honest I haven't found a way to solve it and it is a common problem between users, if you google "weird sound before nvidia drivers crash" or "nvidia kernel stopped responding and recovered successfully" many people suffers from this and it is a quite old problem the worst part it's that it's based on luck since some of my friends doesn't suffer from this and some does, I even changed my desktop graphic's card from a 9800 gtx+ to the ati 4770 vapor edition and still suffered from it with a non nvidia card, then moved to the gtx 460 768mb edition and the problem was there , changed motherboard from the Msi p35 platinum to the asus p45 p5q pro, changed ram from ocz sli ready to ocz stealth, the power supply from ocz to thermaltake with more watts and Amps output, even changed it from wall electrical socket, and... The problem was there, sold it to a friend and he still got the problem, so I bought the y410p and guess what... The problem is there I flashed the bios and tweaked my CPU to be an 4072qm but in some weird cases it shuts down and reverts back the changes, and the problem persist, I got another laptop an asus republic of gamer g51jx-3D which gets hot like hell with a gTs 360m and it doesn't suffer from this. I contacted nvidia regarding the gtx 460 having the issue and they wanted me to send it for repairs but my guarantee was over so I didn't send it. It is not heat problems cause when I game I get around 76 - 80C from both CPU and gpu after I updated the bios, was getting to 80c to 83c in processor before the modded bios and from 90c to 97C in graphic card and the nvidia problem was there, updated all drivers in my Lenovo and I feel like it is doing it more frequently, but oh well I just learned to deal with it, or waiting for someone to get a real fix, people changes some values in the registry to give it a little more wait time before crashing but it didn't solve my problem.... so... It is like having a strange decease which it got no cure, so we learn to live with it until some is found or until death, if you find anything, please share it, I will too.

I've been having strange issues which I suspect started after flashing the bios fixer (btw, I'm on the 1.07 one). The display driver crashes every time I play some game (AC4 and NFS:Rivals as far as I've noticed). "The "Nvidia Windows Kernel Mode Driver 331.93 stopped responding and has recovered successfully" - this is the notification that comes up on the Windows taskbar after I force close the frozen game window using the task manager. As you can see, I am on the latest Nvidia (Beta) driver. I have already tried out most of the recent drivers posted on Nvidia's website without any fruitful results.

The present condition of the laptop has the flashed 1.07 bios with the Intel AC7260 wireless card installed. The rest of the laptop is all stock running Windows 8 at present (I have already tried running Windows 8.1 without the issue being resolved).

After doing some searching around on the internet for a solution, I'm almost certain the problem has got something to do with the inefficient power management (I'm also getting a "compatibility issue with your power management system" warning in the Windows Action Center). Upon a fellow user's suggestion, I tried tweaking the power management settings in the Nvidia Control Panel and set it for maximum performance and yet the same issues remain.

Also tried setting a TDR (timeout detection and recovery) delay value of 8 within the registry and it seemed to work for a short while. But, it seems I'm back to square one at the moment.

I was thinking this might be a bios issue and wondering if there are any settings I need to change so that the power management is better handled. I've been searching around for an updated bios file for the 410p but can't seem to find them anywhere. I'm surprised I am the only one who seems to have this problem; at least I can't find anybody else who has made a remark about this anywhere on the internet. Any help would be appreciated.

Nah it is not the bios it happens to me with most intensive games, sometimes I hear the sound becoming unstable, I fast get out of the game cause if I let it continue I get a BOSD and sometimes the message of nvidia crashed, I've tried everything, this happens with my desktop too which I got a gtx 460 I guess this is an nvidia problem not the bios. This happened after an update?

So is this possible to buy the 650M gt ultrabay and use it in our y410p? I try contacting their reps and I get mixed answers.... the last one I got was that the ultrabay is never coming out as their description in the page doesn't say it supports SLI.... so.... :/ guess I'll have to mod .
