Windows had corrupted which was causing the issues passing over from BIOS, I ran installation media from USB and selected a restore point from there - issue resolved. Cheers folks

The problem is I cant get back into Windows, even after loading the optimised defaults.

Yep, that's what I tried - nothing. If you have a look at the YouTube link I added, that's what happens when I exit BIOS.

Nope, I still cant get it to post even when reverting back to stock.

Thanks for replying both! Nope, I still cant post when going back to stock. My issue is getting Windows to boot normally.

Hi All, Specs Windows 10 64-bit i7-4790K ASUS Z87M-PLUS Corsair H100 AIO Corsair CX650 PSU GTX 1070 500GB SSD (Windows installed here) / 1TB HDD. Decided to finally get round to OC'ing my i7-4790K chip that I've had for a couple of years now. This is my first time OC'ing so after watching a few videos I got to work. I ran a Intel XTU stress test right off the bat with the chip clocked at 4.0GHz - I done this to determine the voltage being consumed under full load which I was then going to use as my manual stock voltage, and work from there. It maxed at 1.179V. I set my manual voltage to 1.180V and cranked it up to 4.4GHz (I know 0.4 is a pretty big jump but I've seen these chips easily surpass 4.4GHz). It blue screened & repaired - at this point I reverted the BIOS settings back to stock and it posted into Windows fine from there. I then went back into BIOS and selected the automatic "ASUS Optimal" overclock feature to get some benchmark figures (this automatically OC'd to 4.5GHz), the plan was to then start tweaking the voltages/speeds until it was optimised. I was unable to post to Windows after making these changes. ...and it ends there, ever since then I've been unable to post past the BIOS. See link below link for posting attempt: https://www.youtube.com/watch?v=RuGoFGwzCyk Troubleshooting Reset CMOS by removing the battery. I also tried bridging on another attempt. Flashing the BIOS back to 1105 (when I initially installed the CPU I had compatibility issues with 1107 which is recommended version on the ASUS site) Using my old i7 4770 CPU None of the above has worked, any thoughts? Cheers, Jude.
