I doubt anyone can tell you that.
Remove the side panel and test.
Remove that odd 1x8GB stick of ram and test.
since my old GPU died, I have problems with random blackscreens - mostly while gaming and espacially while gaming and watching a video (with vlc or on youtube) or chatting via TS. When this crash happens, sound is briefly contorted and both monitors stay on standby. This sometimes happens more than 4 times an hour, sometimes just once per week. Nevertheless its really frustating and even there are tons of those posts out there I hope someone is able to tell me what is wrong.
Mainboard: ASUSTeK P8P67LE Rev X.0x with Sandy Bridge Rev 09 Chipset and P67 Rev B3 Southbrige. BIOS version 3801
CPU: i5 2500 (non-k and not overclocked)
RAM: 16 GB (2x4 + 1x8) DDR3 Dualchannel 686.8 MHz
GPU: NVIDIA GTX 970 EVGA, code name GM204, revision A1, driver version 126.96.36.19994 WHQL (ForceWare 836.47), BIOS version 84.04.1F.00.72
Power supply: Super-Flower SF550P14XE Golden Green Pro 80plus gold (550W)
OS: Windows 7 Home Premium 64 bit
2 Displays: main connected with HDMI, second with DVI. After the "upgrade" of my GPU I resettet the (mainboard) BIOS.
Right now I am using the GPU Driver version 384.94, but in the past also 378.XY and higher
What I already tried:
-reinstall GPU drivers manually with cleaning
-reinstall GPU drivers with DDU, several times
-increasing wait time for the GPU in the registry (can't remember what it was called)
-limited maximal power consumption and/or coreclock (-250mHz) by MSI Afterburner
-used different connection types and combinations for the monitors
-reattached the GPU on the mainboard
-checked for new BIOS versions (GPU / mainboard)
-changed the mainboard BIOS to "legacy" (have to look that up, too, can't remember the exact wording)
-try to find some informations in Windows' event-logger
With GPU-Z, I was able to log one recent crash:crashlog<br>
