Question

New pc has crashing issues.

Mar 6, 2017 3:16PM PST

So I just built a new rig and I am having problems with it crashing under certain circumstances. I have no problems while browsing or while running stress tests like furmark or prime 95. However when running some games like Rome 2 total war or dark souls prepare to die edition, the damn thing will crash and will either refuse to post until I flip the switch on the PSU on and off again or will reboot and show the Asus surge protection was activated. I am running a PC with: an xfx rx 480, an Asus m5a78l-m motherboard, 2 of the 8 GB ddr3 ballistyx ram, and an amd 645 x4 3.1 ghz processor and an EVGA 500w 80+ white power supply. I have used a PSU tester made by ultra and the PSU checks out as far as that thing goes. My bios is completely up to date and came that way out of the box and my graphics drivers are up to date also. Any help to save my new machine would be amazing, thanks!

Warranty time.

All new parts. Call supplier and ask what they want to exchange.

Remember I take it this is not some crack OS and not overclocked.

Well that may not even work
Mar 6, 2017 3:37PM PST

That would take weeks or months for the things I can get manufacturer warranty on, however the CPU was bought second hand. All in all that is not a workable solution for me. By the way I'm running windows 7 with no OC. Thanks anyway though.

Then the other test.

Install a Linux and stress test there. Too bad about the used part. Usually why folk dump things like that.

AMD rigs are notorious for this here. When we see this, we quote out new motherboard, CPU, RAM and PSU. Maker's do not have good diagnostics and by law we can not exceed a repair quote.

Be sure to google that motherboard with the words "crashing" and "reboot".

Well, I do have a version of tails on a flash drive..
Mar 6, 2017 3:50PM PST

However as for searching for similar problems with the mono, seems that it could be anything from a bad PSU to driver conflicts and anywhere in between. I will try that Linux idea out in a few hours and get back to you, thanks.

How old is that CPU?

That's an interesting idea!
Mar 6, 2017 4:11PM PST

I'll give that a shot right away.

I've never actually under clocked
Mar 6, 2017 4:13PM PST

Do you think I should leave voltage settings on auto for that?

For underclocking

Well just the under clock didn't work..
Mar 6, 2017 5:00PM PST

I tried the under clock by lowering my multiplier in half, the game had a lower frame rate and still crashed. I'm going to go back to standard clock, is there a way to select specifically which cores get disabled with this setting?

Sorry no.
Mar 6, 2017 5:02PM PST

But it has helped me find out if it's the CPU. Remember, as I worked repair shops (not as tech but lead or owner) you won't see me build what you built. They just show up too often with crash issues.

Hold on a second here..

That option in ms config is just for booting, not for application usage.

Nevermind
Mar 6, 2017 5:14PM PST

After a reboot I see that I was wrong.

It's one of the tools I've used to sniff this out.
Mar 6, 2017 5:25PM PST

I was a bit worried about the CPU Watts and the PSU but that should be OK. Unless the motherboard is used too.

Still testing on single core
Mar 6, 2017 5:28PM PST

However the Motherboard is brand new, as is the PSU and obviously the GPU since they just came out not too long ago.

Well I crashed on single core..
Mar 6, 2017 5:33PM PST

So either that one core is bad, or it's something else.

Given all the new parts.
Mar 6, 2017 5:43PM PST

There's not much to point to but that CPU or the install.

I'm not there to check your work. That is, heat sink compound, issues that folk get into with mismatched RAM, old CPUs, recycled, old parts.

Crashing on a single core points to basic issues. Motherboard, CPU, RAM.

I doubt it was the thermal paste.
Mar 6, 2017 5:54PM PST

I applied it exactly as arctic fox and amd recommend, and the stress tests never got the thing too hot. I will order more thermal paste and get back to you in a few days when it arrives, I will also be able to try out a different mother board with an Intel pentium anniversary edition. Thanks so much for all of your help.

I always have to ask.

There are many reasons for this machine to do that but the recurring fix for the AMD shop hounds has been new CPU and motherboard and too often RAM and a shiny single rail PSU that we step up in size.

We've tried to pull this back from the edge with underclocking and running single core.

There's a little more in some BIOS's such as disabling L2/L3 cache and Virtual Technologies but we only do that in extreme cases where we don't have spare parts to fix and the client wants to limp along till parts arrive.
