BSODing while playing games.

[coolbyte]

Hello, i've bought a PackardBell TJ65 4 months ago. Since then i've been experiencing problems while playing any games. I get a random bsod. However, i reformatted the C: drive and installed a full retail Windows 7 Ultimate x64 2 days ago. Unfortunately that didn't solve my problem.

Here's what windows says:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
Additional information about the problem:
BCCode: 50
BCP1: FFFFCDA00A2E494C
BCP2: 0000000000000000
BCP3: FFFFF80002F6874D
BCP4: 0000000000000007
OS Version: 6_1_7600
Service Pack: 0_0
Product: 256_1

I also attached all the files that may help, thanks for your concern.

Edit: I got 2 nvlddmkm.sys related BSOD also, I'm attaching the mini dump.

I suspect some kind of hardware problem, honestly. Let's get the software causes out of the way though.

Start by removing Bit Defender with this tool: http://www.bitdefender.com/uninstall

Reset the Windows firewall. Open an elevated command prompt and enter netsh advfirewall reset.

Install MSE: http://www.microsoft.com/security_essentials

Install these Intel WiFi drivers:  Intel® PRO/Wireless and WiFi Link Drivers-Only for Windows 7*

Then, time to work on some hardware causes. First, test your video card, because 2 dumps blamed your nVidia card. Use this tutorial: http://www.sevenforums.com/tutorials/100356-video-card-stress-test-furmark.html

Be sure to report the temps it reports.

Next, test RAM. http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

I did everything but the ram test. I ran furmark for 1:30 hours, max temp was 71 Celsius, no artifacts.

Okay, maybe you can run the RAM test during the night.

Video card looks good, although no hardware test is always accurate.

Let's hope no more BSODs now.

Okay the ram test was way bad, about 7 million errors, attaching the pics. Hope the warranty covers this issue.

Sounds like a compatibility issue to be honest. Try Part 3 of the tutorial to find out: http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html
