The majority of the time this laptop runs perfectly fine, and I have little issue with it. However, when I start a heavy program or game, that can be a different story.

I can easily run some/most games at medium-medium high graphical settings and get a solid 60-70 FPS with the nvidia GTX 950 that's inside. Depending on how demanding the game/program is, it will run about 30-40 seconds at a time before facing a lag spike, where the FPS drops from 60-70 FPS to about 1-2 for a period of about 1 second. In especially intensive situations, these can occur every 10-15 seconds. This has proven to be very irritating overtime, and makes some games unplayable.

I'm lead to believe that this may be a heat problem. I've bought a laptop cooling pad, but so far, that hasn't seemed to do a whole lot to aid this. This is backed up further by testing out games with the lower-end graphic settings. When I did these tests, I found that the spikes where less common, while the occasional spike still happens. When I opened up a temperature-viewing program, (I used HWMonitor), it reported back to me that the processor's temp was at most 210 F, and the nvidia GTX 950 was at most 176 F. (I'm no expert, but that seems a bit high...) This was when I had the most intensive game open on the highest (stable) graphical setting, a setting that runs fine, with the exception of the lag spikes.

Also, due to the fact the surface of the laptop is brush metal, the area above the fan becomes nearly painful to the touch when it's on its most intensive apps.

I bought the laptop very slightly used, so it's nearly new. I haven't modified it at all.

Specs:

Intel i7 5500 U 240 Ghz
12 GB of RAM
Nvidia GeForce GTX 950M w/ 15.6 inch display
(cooling pad)

Thanks in advance to anyone with advice/solutions
 
Hi,

Please do try these troubleshooting steps that may help in solving the issue.
- Start by doing a clean install of the graphics card driver.
- Go to Device Manager and uninstall the Nvidia graphics driver.
- Once done, open Programs and Features then uninstall anything related to Nvidia.
- Next is to download and install the latest driver.
- Here's the link: http://www.nvidia.com/Download/index.aspx
- Reboot the laptop after installing the latest driver.
- After the reboot, set Nvidia as the default GPU.
- Here's how: http://nvidia.custhelp.com/app/answers/detail/a_id/2615/~/how-do-i-customize-optimus-profiles-and-settings%3F
- If the same problem will persist I would also suggest opening the laptop and clean the dust off the fans and apply new thermal paste on both the CPU and GPU.

I've determined that neither the drivers, nor the fan intake/outtakes were the problem. Could it possibly be something other than thermal paste that needs replacing? Could it be possible something else is to blame in this situation? If not, I'll take it in to a repair shop tomorrow, no big deal. Thanks for the help
