I was playing Battlefield 4 on my Haswell i7 rig and there have been a few `glitch issues` over the past few weeks culminating tonite in the PC shutting down and getting locked before being able to get into BIOS (PC told me to alter something in Ram in BIOS when it re-booted). However, 5 minutes of cooling and it started up again; but as I switched the power back on and was looking in the PC I saw sparks flying near the RAM and the motherboard. The A-Data ram has defaulted from its XPG 1866 normal status down to 1333? (sub-normal for this ram). The Samsung SSD and Windows 8 Pro (x64) is fine. Nothing is overclocked. I don`t overclock. Even the i7 is a standard 4770 with no overclocking. The iChiLL GTX 780 seems fine. It was hot though. I could not get a temperature reading as the PC had shut down. Its currently doing 57DegC on a TechPowerUp GPU-Z render test. The i7 seems to be fine. The Asus Sabertooth Z87 seems to be working and the software indicates no problems. Any ideas about the sparks? I can smell the light burning smell, but cannot see anything beneath the Sabertooth thermal armor? P.S. For weeks, after an hours BF4 play I have been having the PC AUTOMATICALLY putting me into and locking me into BF4 Console... And sometimes I have had to re-boot to get out of the glitch. Cold that be down to faulty A-Data Ram? Could the sparks be from (what was) the V Hot Ram? I am running it at the mo. but will not go back into the game.
