Lots of BSODs different processes RAM problems?

Hi, My friend is having a lot of blue screens, so I thought I'd check them with windbg and I'm a newbie so I just looked at the processes, bucket ids and googled them to see if anyone else has the problems, I am now clueless because they all seem to be different and so I need an experts opinion. I have attached all of the minidumps, I can get him to run the system finder bit if you need.

His specs are as follows:
i5 4440
8GB RAM
Windows 7
2TB HDD
Palit GTX 750 Ti graphics card


If you need any more info, please ask.
Thanks!

Hi.

Before suggesting anything, it will be better to see the required data as per BSOD posting instructions.

Click on button below ....

It will download the DM log collector. Right click on the application and run as administrator. It will generate a .zip file on your desktop. Upload the .zip.

Also, it cannot be nullified that there is a high probability that the memory is failing, anyhow. So, test your RAM modules for possible errors.

How to Test and Diagnose RAM Issues with Memtest86+

Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Let us know the results. Further troubleshooting may be needed depending on the results.
