GA-Z97X-Gaming-5 MSI GTX 970-Gaming-4 boot issues, bios resets

[cz4r]

Hi,

having problems after installing brand new gtx970, rig details at the end. All is plugged in correctly no issues found during gaming / benchamarks. No system / card overheating. Default BIOS settings. Bios version F6.

Steps to reproduce:
1. Play for some time / run benchmark for 15 minuts (not mandatary, issues appear sometimes without even playing)
2. Shutdown PC
3. Start PC

Result / problem found:
1. PC won't boot, black screen.
2. Fans on cpu/gpu turn for a second, than 'eeek' from mainboard then repeat, fans, 'eeek', repeat.

Some workarounds i found:
1. Hold power button little longer - boots eventually but not always, bios reset to default happened  at least once
2. Shutdown whole thing, wait some time, power on again, boots properly.

Apart from that having another issue with this mobo - occasional bios resets to default which happened even before installing gtx 970. What is going on? Board has approx 4 months, is it faulty? Will provide additional info if needed.

Try taking the new card out and seeing if the issues continue. If they stop (the issues) then you know the answer lays in either the card, the slot itself/motherboard or connections.

I went through this with my old system....turns out it was the PSU. I change out PSU with a known working PSU and it fired right up.

Checked the rig with another 600W PSU which my buddy owns and has no issues with.
All worked fine, seems like shi**y / faulty PSU is indeed the root cause ..

Yup PSU, changed for Be quiet 600W no issues.
Thread can be closed, thanks.
