Hi again guys, First off, I want to thank everyone who has helped so far, I really appreciate you offering me advice. I flashed to the newest BIOS, and for two days it POSTed first time. Then a few days ago it started struggling again. I checked the BIOS settings and it was exactly as I set it earlier, it hadn't changed to safety settings. Anecdotally, I noticed that on cold mornings it takes more tries to boot than on warm ones. Could this be related? The house I moved to recently is much colder than the apartment I was in, and that's when the problem started.

I ran Memtest86 v6, and attached two pictures of it (sorry for the poor quality). I've never used it before, so not too sure what to make of it, but I like the 0 errors part. After the test I went into the BIOS to check the XMP settings, they were disabled and the ram was clocked at 1000MHz. I enabled XMP at it clocked up to 2133MHz @1.5V which is what I thought it was running at the whole time. I also flashed the BIOS to the newest version.

Thanks for the reposnses guys. I ran memtest86, but miscalculated how long it would take so had to stop stop about half way, but no errors up till then. Ill have enough time tomorrow to run it fully, and ill see what it says. Ccokeman, sorry but i only understood about half of what you suggested to do . Could you explain how to set memory Mhz? Im also not sure how to change the XMP settings. Also, which memory settings page are you refering to? Sorry to be such a noob, this is my first solo build, and also my first time looking at overclocking. Thanks again for your advice.

Hey Everyone, I build a PC in January 2014, and it worked great, at least for a while. I moved house in November last year and since then its been having problems booting. When I turn it on, the PSU spins up, all my fan LEDs come on and all my case fans spin, but the motherboard doesn't POST. After about 20 seconds, it shuts down, and about 10 seconds after that, it restarts, with no interference from me. This happens anywhere between once and 6 times, then it POSTs and works normally. This only happens the first time I turn the machine on each day, subsequent restarts/re-boots all work first time. I have completely re-assembled the machine twice, cleaning it each time, to no avail. I've also tried starting it with no USBs connected, but no change. Any ideas you guys have would be greatly appreciated.
