PC restarting ocasionally

[bejamartins]

So this PC ocasionally shuts down for no given reason

 

The hardware is:

AMD A10 5800K

Asus A68HM-Plus Board

4 GB DDR3 HyperX Fury x 1

GTX 260 (Previous Gt 520, also did the same thing)

Corsair VS450 PSU

1Life card reader

 

No warnings on Windows Log (aside the unexpected reboot). Mem test says ok, gpu stress seems fine.

 

Crashes more often during I/O in external HDD, also crashes inside Sims 4 often. Occasionally crashes idle in Windows.

 

Update history in second post.

Update 1: using Heavy Load, with "enable full cpu load" it crashes.

Going to try to update bios and chipset drivers and try again, if not working, going to disable turbo boost and try again.

 

Update 2:  Did noticed there was an overclocking profile loaded called "Globaldata" (Globaddata is the name of the boutique where the PC was bought). After upgrading BIOS, all settings were cleared, including that profile, lets see if made a difference.

 

Update 3:  Updating/clearing BIOS +  chipset is allowing me me to run Heavy Load with  "enable full cpu load" on.

 

Update 4: Crashed again, also noted a pattern: last message before crash on Windows log is an Avira component. Also notice that an intensive copy/installation may often cause the crash. I uninstalled Avira, and now am repeating other conditions of the last crashes.

 

Update 5: Nope, no different result...

 

Update 6: Disabling AMD PowerNow seem to have dealt with the rest of the crashes occurring  I believe there is a compatibility problem with some (Asus?) boards and AMD CPUs of different ages when it comes to features dealing with CPU clock change (dynamic and static).

 

Update 7: False positive...

 

Update 8: It seems it had to do with voltage spikes.

Im wondering if its just AMD cpu's because it happens to my brother and he has the AMD A6 6400K

Maybe.

OK, got it and I think I discovered why and might be the same with your brothers.

 

After tweaking around with the CPU options, manage to get it stable. Mostly what I done was to disable anything that messed with the CPU clock, in my case, first light overclocking made by the boutique and then disabling AMD PowerNow. (Also upgraded BIOS first, that seem to help, and makes sense if it brings more compatibility). After googling a bit and finding a few people that had similar problems and complain to Asus, their response seem to be that older boards with newer AMD's CPUs for that socket may have compatibility issues. Not sure why, but compatibility seems to do specially with dynamic clocks and, for some reason, sometimes simply with not default clock speeds. My case seem to be the other way around, and older CPU (2012) with a newer board (2015).

 

Anyway, if I may ask, what board and CPU models are is your brother using?

 

Edit: after an afternoon stable, crashed again...

An MSI motherboard is what my brother uses, which is why i was pointing my finger at the CPU itself

I ended up concluding that it was due to voltage spikes. Bought a safety power outlet and seems stable so far. Thing is, it seems, AMD CPUs,draw more power than Intel ones, and if the electricity isn't stable, it shuts down. Dunno if it is the same problem or not with your brother, but might as well check.

His cpu is of the same socket type as yours, so it may very well be voltage spikes, and in my house, the wiring needs to be upgraded thru out the house

My house, well, if it rains a lot, the wires go nuts. It hasn't rained until this week here, so I didn't suspect that PC's outlet. Now I realize that one is particular screwed up.

 

This week rained a lot, so an older PC of mine had its PSU died out.

 

Anyway, maybe a good investment for him would be an UPS. So would be for me xD.
