My system turns itself off suddenly without warning. After initially happening rarely, this has gradually become more frequent to the point where it's borderline unusable now - while random it typically happens after less than an hour now. Initially it happens more under load, but again, now, seems to just happen anyway.
I have
- AMD FX8350 on gigabyte motheboard (can dig out model if useful).
- 4*4gb, 2*8gb DDX3
- Coolermaster hyper 12 Evo Fan.
- 2 graphics cards, a GT440 and a GTX 1070 I recently upgraded to do machine learning/neural network stuff on.
- Various hard drives and one system SSD
- Corsair CX 750N
I'm running Windows 7 home premium (which means at present I can't access all the RAM, but had same issue previously with Win 7 pro - I went back as part of troubleshooting this.
I also have to reflash my BIOS quite frequently from the backup, as I am told it's corrupt on boot. IIRC this started before the power downs, and still does from time to time.
After the power loss, I have generally pull the plug out and put it back in and flick the on off switch at the back before the power button on the box will turn it on again. Sometimes I also have to wait.
I initially put the power downs down to my CPU overheating, and bought an aftermarket fan, but core temp now indicates the CPU is running at a sensible temp (25-30 degrees - before it was frequently going above 60).
I've narrowed it down to the new graphics card - GTX1070 - or the PSU - as the issues are now repeatable when I put the card under load. The PSU gets hot - at present it's 41 degrees C with just the old graphics card in, but my understanding is it should be quite capable of handling that kind of load without issue.
- How hot are PSUs mean't to run? At what point does one think there is an issue
- How can I diagnose whether it's the PSU or the card and prove it so I can replace and (if it's the card) get a refund under guarantee.
- Could it be something lame like graphics drivers?
Thanks!
