I searched already windows support. The awnser is this: This scenario usually indicates a problem with the hardware. To help isolate the problem, check the following items: 1. Overclocking: Disable overclocking to see whether the issue occurs when the system is run at the correct speed. (I have never overclocked cpu or gpu). 2. Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is the same speed and that it is configured correctly in the system. (I ran memtest overnight with no problems) 3. Power supply: Make sure that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices can require more energy than the current power supply can provide consistently. (I had no problems with wattage and the only thing i added that requires more energy was the K95 RGB keyboard which needs 5V as i can see from the bottom sticker...) 4. Overheating: Check whether the system is overheating by examining the internal temperature of the hardware. [Desktop pc has 2x120mm front/rear, 2x140mm side/top and a Cooler Master Hyper 212 EVO CPU Cooler. Maximum temperature for GPU is 52C, and CPU 50C in 100% usage (stress test).] 5. Defaults: Reset the system back to the system defaults to see whether the issues occur when the system is running in its default configuration. (I formated the SSD and reinstall windows 7 ultimate 64bit. Installed factory drivers from MoBo and GPU CD. Reboot while playing CSGO happened again. I made all possible updates (drivers, Microsoft Net Framework, Windows, BIOS) and it's still happening.) For now, my desktop is back for hardware check up. No matter what, i'll update my news. If there are no hardware problems i am sure 99% that keyboard causes failure from the moment it is attached and it's drivers installed. If they don't find anything suspicious, i'll try one last thing. Another format, reinstall windows, update drivers and use my old keyboard without connecting and installing drivers and CUE of K95 RGB. Thank you for your time zheren159! :)

All drivers are up to date, bios is also updated and no it doesn't blue screen. It's running perfectly, no lags, no other issues and suddenly ''BOOM''. reboot, after 15 seconds back to desktop with critical error in Event Viewer: [Kernel Power 41, Task category (63) - The system randomly restarts and no Stop error BugcheckCode is listed.] Critical Error: Kernel-Power Event Data - System - Provider [ Name] Microsoft-Windows-Kernel-Power [ Guid] {331C3B3A-2005-44C2-AC5E-77220C37D6B4} EventID 41 Version 2 Level 1 Task 63 Opcode 0 Keywords 0x8000000000000002 - TimeCreated [ SystemTime] 2015-11-19T08:50:11.131609800Z EventRecordID 175362 Correlation - Execution [ ProcessID] 4 [ ThreadID] 8 Channel System Computer Corsair-PC - Security [ UserID] S-1-5-18 - EventData BugcheckCode 0 BugcheckParameter1 0x0 BugcheckParameter2 0x0 BugcheckParameter3 0x0 BugcheckParameter4 0x0 SleepInProgress false PowerButtonTimestamp 0

I did uninstall CUE and it happened again. Then i plugged in my old keyboard and happened again. Probably it was just a coincidence that reboots started from the moment i plugged in the K95 RGB. Now i have to triple check my RAM and PSU. I have already made several stress tests to GPU and CPU with low temps and no rebooting.. At least i have ruled out some worries. Thanks for your advice.

Alright, i'll try to uninstall CUE and check it for a few days. I'll update any news. Thank you for your thread and consideration.

I don't know if my problem is caused by CUE but as long as I installed the K95 RGB and updated with the latest drivers and firmware my pc randomly reboots. Actually it only reboots while playing CSGO. It can reboot in the 1st second of gaming or after 3hours. Just random. No overheating issues, not faulty PSU/CPU/GPU/RAM/MOBO, no changes in PC-drivers (only the latest driver installed of CUE). I ended up asking in Corsair Community because every other software/hardware part seems to be ok. Running out of ideas and problem still exists. I feel so bad for my 1,5 year old desktop.
