Before I begin with my current round of issues, Let me give a bit of background of my history with the Asus P8Z77-V Pro / Thunderbolt motherboard. Board works fine for about a year and a half - 2 years. I begin to get timing errors with my video card, that get worse and worse. Eventually I get to pink screening. After doing a lot of testing and figuring out that it was not a software problem, i tested multiple video cards on my board. Every card that required PCI power, either would barely work or not work at all. The only cards I had that would work were old video cards that did not receive additional power from the power supply. I did run tests on my power supply and could not find any issues. There was a few times where Asus power surge protection kicked in before the this all came about. I since bought a CyberPower UPS and have used that ever since. I do RMA#1 and get my same motherboard back, and it works perfectly for the first week or so. Then about a week and a half it doesn't post one morning when i turn it on, with the RAM LED turned RED. Able to get it to post after a few times trying. Next couple of days computer runs fine, I test my RAM via windows and also MemTest and RAM tests fine. A few days later, my computer will no longer post. After about 5 calls Asus tech support, they finally agree to send me an advance RMA. and here's where my new problems start: Problem description: The first issue I notice is that after I set the time in BIOS, it didn't seem to take in Windows. I also notice when I go back into bios it often resets. Now when I go into BIOS, every time I boot I get this as the time and date and I cannot manually adjust it.  Also, sometimes when I boot up, I will not get a post and the VGA-led will be red. Then I try to boot again and it will post, but tell me that I have an overclock failure. I have barely touched the defaults in bios and have not attempted to do any overclocking. Also, whenever I do exit bios, it will always freeze at the end of the windows splash screen. I have to restart, where it automatically goes into startup repair, cancel that and then the computer will boot normally. This is consistent whenever I go into and then exit the BIOS. I have not noticed any video card problems but have not really tested it with any powerful 3D games yet(mostly been playing 2D platformers but they've been running fine). I did have a NVIDIA background program(forget which one) crash on me once though Attempted fixes: As far as the issue with the time goes, I figured it was possibly the CMOS battery, I have changed that with the battery from my previous dead Asus motherboard before i sent it back to ASUS as part of my advanced RMA, this did not fix the issue. As far as the overclocking errors, I did some google searching and did not seem to find a satisfactory solution that actually fit my problem. BIOS is version 2104 - the latest version. This is probably my last hurrah with this motherboard, if I can't solve this I'm probably not going to do a 3rd RMA and just find a motherboard that hopefully isn't prone to a lot of problems Recent changes: Only change was I got a new Corsair RM850 power supply. -- Operating system: Windows 7 64-bit. System specs: Motherboard: ASUS P8Z77-V PRO/THUNDERBOLT Processor: Intel Core i7-3770k Ivy Bridge 3.5GHZ (3.9GHZ turbo) LGA 1155 77W quad-core RAM: Corsair Vengence 8GB DDR3 1866 (2 X 4GB) Video Card: Nvida Geforce GTX 560 TI Location: U S A! U S A! I have Googled and read the FAQ: Yes

What's your power supply? Full brand name and model number, not just wattage.

So the problems running a pci-e graphics card with a power connection happened after you installed the corsair 850? Or is that problem no longer happening? As far as the overclock thing, some bios settings will attempt to do a mild overclock by default.

Factory Factory posted:What's your power supply? Full brand name and model number, not just wattage. Oh, durr, it was there, but hidden away not in the parts list. Corsair's RM is a good unit, but even good units can have lemons. First check to make sure the unit isn't covered by a recall order. If it is, RMA it regardless of any further testing results. After that, do you have a spare PSU you can test with? Also, how does the system run with the graphics card removed, using integrated graphics?
