Black screen crash or reboot
Tl;Dr system crashes to black screen or just reboots, system board q code 90. Do I just replace cpu or both cpu and mobo?
Over the last few months I have had an issue that has progressively gotten worse with random reboots or black screen crashes. Most of the hardware is out of warranty by a few months.
Specs:
Amd 3700x
Msi unify x570 motherboard
4x8GB team group CL15 3600 memory (overclocked timings)
Evga 3080
Two sata ssd
1 sata hdd
2 m.2 ssd (most recent one installed a few months before this started)
Evga 1000w platinum psu
Thermaltake x9 case
Custom water loop with dual 480mm rads only cooling the cpu (previous build also cooled gpu)
Dual 200mm intake fans
Case, psu, cooling, sata drives came from last build. Previous build had stability issues with TDR errors.
The current build was fine for a little over 3 years (gpu a little less) then about 2 months ago I had a blue screen TDR error, then it started crashing to a black screen occasionally maybe once a week or so then after a month or so it would sometimes just reboot and not black screen in addition to still black screen, no errors in event viewer aside from unexpected reboot. The frequency slowly increased to multiple times a day. I ordered a replacement power supply, 1300w super flower, assuming that was the problem because of the lack of other errors and the power supply being from the previous build. Before I install it system is stable for 3 weeks without a single crash before happening again and not even making through post before black screening again.
I replace the power supply, it works for about 3 hours then black screen, and now it won’t boot to my primary windows install, it sees the drive in bios just doesn’t see it as Bootable. I have a second windows install and that boots and I can access files from the primary drive but right clicking in windows explorer just crashes windows explorer. After a few hours in this windows it black screens and now will only give me video every few boots and usually black screens after a few minutes.
I noticed now that the system board q code is 90 and other threads have said this is cpu/mobo. I can’t decide if I should buy a 5800x3d and try it on this board and hope it’s the cpu or if I should buy a 7800x3d a new board and ddr5 to just eliminate all of the possibilities. Or if there is more troubleshooting I can do.
