BSOD while playing various games in Steam, Win7 Ultimate x64

Hello, jakezuku I'll see if I can help you. Please do something for me first.

Please fill out your System Specs

   Information

Your System Specs will help us to help you, and doing it in this manner will make them available to all helpers in every post and keep us from hunting for them. We ask that you fill them out in as much detail as possible including Desktop or Laptop, Model number if it is an OEM computer and all components with the Manufacturer and Model number if possible.

If you will go to your last post and click the 'System Specs' in the bottom left of the post, you will find a link to update your system specs. Please fill those out in as much detail as possible, making sure to click save at the bottom of the page. If you would like to know what we would like, you can click 'My System Specs' at the bottom left of this post to see mine. If you do not know what your components are, this will help you accomplish this task. System Info - See Your System Specs

Please Run Memtest86+

   Information

Please download from this site only http://www.memtest.org/ in the middle of the page are the Download links, you can download the ISO.zip or the Auto USB Flash Drive installer.zip

Extract the Zip file. If you chose the ISO image, burn it to a CD using Windows Disk Image Burner or any Image burner you may have. If you downloaded the Auto USB installer, extract it, insert your USB 2.0 Flash Drive and take note of the drive letter. Run the installer, select the Flash Drive Letter, check the format box and press next. It will install memtest86+ to a flash drive. You can use either V4.20 or V5.01. Boot from your selected media. If you use V5.01 it will tell you to press certain buttons at the start, please press no buttons. The test will begin on it's own and continue to run until you stop it. It needs to run for 8 complete passes or until you receive an error. If you receive an error, stop the test. Even 1 error is a fail. Each pass tests a different part of the ram and each of the 10 tests in each pass tests something different. It takes a minimum of 8 passes to completely test the ram, more passes are better. It is quite a long test and will take several hours depending on how much ram you have. Due to the time length it is best to run overnight. If you have any questions, please do not hesitate to ask

Thanks for the specs. They will help us help you.

Run both sticks, one at a time in each dimm slot. Keep track of which stick and each slot. I'm sure you know the test failed. We now need to find out if the ram is bad or there is a problem with the Dimm slots on the board. This will answer that question.

Check stick #1 in Dimm slot 1, then the same stick in Dimm Slot #2 then 3 then 4, keeping track of errors and which slots with each stick. Then check the next stick the same way.

No Problem. Take your time and do it when you can.
