http:// - DMP FILES HERE. Hi, I recently built my first PC (about 2 weeks ago or so) and I have been getting BSOD while playing games. The BSOD only has happened on Call of Duty World at War while loading a custom zombie map, Battlefield 3 and Battlefield bad company 2 from just playing for a few minutes and planetside 2 just after I installed it and tried to launch it. Although it never happened to planetside 2 on start up again. I have tried many things such as reinstalling windows 7, reinstalling drivers and the games, switching the ram to the other two slots. Nothing works! I also tried doing stress tests such as 3DMARK 11 and Furmark for the GPU, no crashes! I went to bluescreenview and every dmp file says its caused by ntoskrnl.exe. On another forum someone decoded the dump files and he said is most likely memory related. However, I just switched the ram to new kingston ram I bought. That didnt fix it. I also have Minecraft and it has never happened while playing that game even after like a 5 hour session. It also has never happened while doing anything besides playing the games I mentioned earlier. The STOP error I get is 0x0000007e Please help! I will attach my last 5 dmp files in this post.

System Specs:

Windows 7 Home Premium 64 bit
i7-3770k stock clocks (Cooled with an arctic cooling freezer 13 air cooler)
EVGA GTX 670 FTW
Corsair TX750 V2 PSU
1 TB Seagate Barracuda 7200 RPM HDD
ASUS P8Z77-V LE PLUS motherboard
8GB G.Skill RipJawsX series 1600MHz 1.5v RAM (Now Kingston HyperX Plug n Play 1600MHz 1.5v)
4 Case Fans
 
Solution
this is what I found in you dump files:

crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: ntkrpamp.exe (nt!Kei386EoiHelper+0x17D4)
Bugcheck code: 0x7F (0x8, 0xFFFFFFFF8E503750, 0x0, 0x0)
Error: UNEXPECTED_KERNEL_MODE_TRAP
Bug check description: This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: ntkrpamp.exe .
Google query: ntkrpamp.exe UNEXPECTED_KERNEL_MODE_TRAP

crash dump file: C:\Windows\Minidump\072413-13088-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x851E0)...

Ok, I'll uninstall those updates but I will also mention that my windows disk look really messed up on the sides, like its a lighter colour on the edges and at some points that lighter colour dips in farther onto the disc. Also I tried using integrated graphics on my i7 but when I booted up the resolution was 640x480 and things were distorted. Could this be because I still had my other gpu in at the same time? Or maybe I have a bad mobo or cpu? Or the windows installation disk is messed up?
 

I took out my GPU and am now using my onboard graphics. I played BF3 for about an hour and I heard a buzzing noise then the screen went black and the computer restarted. No blue screen. It also just happened reinstalling Bad Company 2 but has not happened in Crysis 3.
