Hi,
Sorry for the loooonnnng post.
Hi I'm looking for some ideas, as of last week my PC keeps rebooting or freezing on boot-up.
I've had my PC for nearly 5 and a half years, and it's been overclocked since day 1 and been perfectly stable.
PC Specs:
ASUS P8-Z77-V
i7 3770K @4.6GHz
Custom loop CPU only (EK Supreme water block, EK pump/ res, XSPC RX360 rad, 6x Corsair SP120 fans in push/ pull).
2xSSD
Gigabyte RX 480 G1 Gaming 4GB (non-reference with 8 pin PCI-E connector)
XFX 850W Black Edition
Fractal Design R5 (4 chassis fans + custom loop = lots of airflow)
Windows 10
Last Saturday after a long gaming session, while in the game menus the PC rebooted, reloaded Windows fine, but only lasted about 20 minutes before rebooting again. Back into windows and it lasted about 10 minutes. I kept checking temps throughout and all were fine and the later reboots were went it was just idle in Windows.
I tried turning it off, removing the power and left it for a few minutes, when I tried it again it lasted about 10 minutes before rebooting. The reboot cycles got shorter and shorter until it just hung at post.
That evening I removed the videocard and OC and it worked, I ran Cinebench a few times and temps were still good. I put the videocard back in, and all was fine. I again ran Cinebench, and the AotS benchmarks and it seemed fixed.
The next day while starting a LAN game it rebooted, only this time for it to hang on bootup after POST with a blank screen. I turned it off, left it and tried again a little later, but experienced the same result.
Later that night I tried again but it wouldn't boot to windows, I tried without the videocard but Windows was damaged. At this point I thought it might have been the SSD, so I removed the boot drive and tried to installed windows on second SSD with varying degrees of success. I could get it past most of the install but it would hang on the final "Getting things Ready" screen. I tried to run MemTest86+ but the USB wouldn't boot, despite showing up as UEFI device in the BIOS.
I left it a few days while I researched PSU's and when I came back to it last night, it booted up and went to the Repair Your Windows screen, I tried to reinstall Windows and it worked first time.
I downloaded Open Hardware Monitor and the temps were good. I left it on for about an hour and it was fine with the usual good temps. I clocked it back to 4.5GHz and ran Prime95 for about an hour and it was fine.
Tonight it was still fine, so I re-installed the RX480, and instantly it hung on the Windows load screen (spinning dots). I turned it off left it for a few minutes and tried again, same thing. I read something on the net about UEFI legacy mode, so turned off the compatibility mode stuff, but it mad no difference. I Tried again without the RX480 and it worked fine, even checked temps with Prime95 and they were fine.
I then tried an HD7750 and it hung on Windows boot as did the RX 480. Turned on UEFI compatibility but it made no difference.
I then removed the HD 7750 and went back to the iGPU, and the system booted fine with good temps. Then after about 30 minutes it rebooted, and then again after about 10 more minutes. At which point I turned it off.
Any ideas what's wrong, my initial thoughts were the PSU, then the RX 480, then the motherboard, but now I'm thinking it's the PSU again? I haven't got a spare PSU to test and don't really want to buy one if it turns out to be the motherboard or something else.
