Hey guys,

I just had a couple of questions. First of all, about five and a half months ago I built my own loop. Everything is running great but I was just wondering when I would need to replace the distilled water I'm using (I'm using a Mayhems silver kill coil as an anti-bacterial). The loop incorporates my two 780ti's and my 4930k with three radiators. My CPU idles at around 15 degrees Celsius and my cards at around 20-25; which i'm more than happy with considering I live in Australia and both the cards and the CPU are overclocjed.

I have however been having an issue with the PC, which I think has to do with my motherboard. (It's an ASrock x79 extreme6). It was really quite cheap and I've had a lot of issues with it; I can't find a stable overclock above 4ghz and while I'm not so experienced with OCing, I've done a few CPU's before and I literally spent weeks trying to find one. In addition, four of the DIMM slots do not work and I cannot run my 2400MHz RAM at any frequency other than 2133Mhz (of course with the correct timings). Anyway, lately my PC has had a couple BSOD's and when I'm playing world of warcraft, I'm CONSTANTLY getting critical-64 errors; something to do with memory not being able to be written. On top of that, my screen has been randomly cutting out, as if the drivers are crashing. I however updated them and have not since had an issue. The main problem for me is the BSOD's and the WoW errors. (I have tried all the typical troubleshooting methods such as clearing the cache.)

Thanks :)

You should try running memtest86 to make sure your memory is working ok.
