1. at first they were non-critical, namely, when switching from one window to another (alt + tab), the screen went blank for exactly a second (black screen), which is very wild. The complete cable from the monitor just froze the picture for milliseconds (barely noticeable) and this is due to G_sync, which was activated only in windowed mode. Okay, I'm used to it.
2. After 2 weeks of use, complete trash.
I start the computer, but it does not boot, there is no image in the picture. I think maybe the RAM is buggy again due to overclocking. I look at the diodes on the motherboard board, and d_ram, which has not passed the POST check, is lit there. I think it’s real RAM, but oh well, I’ll reset the bios now, but it only confused me that the light of the warning diode was burning halfway, reluctantly.
Motherboard  expensive, crosshair VIII impact, on the back there is a special button for resetting the BIOS and a screen for post-codes (each boot error has its own code according to the manual and you can determine what the problem is)
The post code did not give out any according to the manual, it showed 2 zeros, which is also wild for me, I already thought of Khan's mother all of a sudden.
The computer should be cut off with a single press of the power button, but this does not work either. Forced shut-down (holding this button) also does not respond. I turn it off using the button on the power supply. I disassemble the computer. I take out a vidyahu with this product inserted and what do you think?
THE WIRE SHORTED THE WHOLE SYSTEM SHORTING IT THROUGH THE MONITOR
Near the DP connector on the video there was a fierce squeaking in the fuses, similar to the whistle of chokes, and the video began to squeak after it was pulled out of the Pci slot, respectively, in the slot, the voltage was grounded and diverted to the entire system.
I pulled out the DP - the computer started up, everything is ok with the complete cable from the monik. I checked this product on another computer - it's also short
