Possible dying motherboard, need help

Status
Not open for further replies.
Here are my specs:

Video: Nvidia RTX 3080 (EVGA)
CPU: AMD Ryzen 3800XT
Motherboard: ASUS B550-F
SSD: Samsung 980 Pro 2TB
OS: Windows 10 Enterprise
PSU: Superflower Leadex III 850W+ Gold

I built my computer over a year ago and until the last couple months it ran without any problems. But then it started having trouble suggesting there was something wrong with the primary storage drive, a 1TB Gigabyte SSD. It was as if certain boots would go wrong, and after such boots, loading up files would be very slow and opening file explorer would take a very long time - in general performance on basic desktop tasks was extremely poor and everything felt sluggish. In one case the computer wouldn't post at all, and the motherboard was stuck with the boot LED on. Also, the Gigabyte SSD was showing massively inconsistent results on CrystalDiskMark benchmarks, going from say 5000MB/s down to 2000MB/s between sequential write tests on the 1GB test size setting in CrystalDiskMark.

So I replaced the primary SSD with a Samsung 980 Pro 2TB (I mirrored the old drive on the new one). For a couple weeks everything seemed fine. Then, I'm guessing unrelated, my CPU cooler started dying, and I had to replace that. My CPU temps are back to where they should be. But now, I think I'm starting to see weird file loading problems again. Certain applications are at times very slow to load. If you're familiar with CrystalDiskInfo, it usually loads up the SMART info on the storage drives on a device very quickly. Lately when I open it, it sometimes takes so long to open I start wondering if I somehow didn't double-click the app's icon.

To check for more solid evidence of drive failure, I did CrystalDiskMark benchmarking on the Samsung drive, as I'd done on the prior one. On the 1GB test size setting, the Samsung SSD is performing about as well as it did when I first got it. However, I tried some smaller test size settings, such as 64MB, and its speeds are much lower on that. The Samsung SSD gets 6900-7100MB/s on the sequential read tests and about 5100MB/s on the sequential write tests when using a 1GB test size setting in CrystalDiskMark, but it gets as low as 2100MB/s for both sequential read and write tests on the 64MB test size setting. I read somewhere that big discrepancies across test size settings in CrystalDiskMark could indicate a problem, but it was an isolated comment and I couldn't find more info about this. Oddly, in Samsung Magician, different test sizes don't seem to affect the drive's performance.

Could there be something wrong with my motherboard that started killing my Gigabyte SSD and is now killing the Samsung one? It seems possible that there isn't actually anything wrong with the Samsung SSD, but some of these problems are looking reminiscent of those that the dying Gigabyte drive exhibited. The performance of my memory, CPU, and GPU haven't changed at all over time in benchmarks. Error testing of the memory didn't indicate any problems. As such I don't suspect there's anything wrong with the PSU. Also, I've got a Western Digital 1TB SSD in the secondary M2 slot, and its performance has been rock solid since I first built this machine. It doesn't exhibit much performance discrepancy at all across the 64MB and 1GB CrystalDiskMark test size settings.

This has become quite frustrating and I'm considering buying a new computer so that I don't have to keep playing error-fixing whack-a-mole with this one. I didn't enjoy building this PC, so I'd have to go with a system integrator or prebuilt, and, also annoying, options on both fronts don't seem too great, so if I could get to the bottom of the current problem, I'd rather do that and keep this PC.

Any help would really be appreciated.
 
A few questions to help us get started:

When you ran Samsung Magician, did you overprovision your drive? You should have at least 10-15% unpartitioned to maximize drive speeds.

Furthermore, is your drive's firmware up to date? The Magician software allows this to be done/checked as well.

Have you ran Disk Cleanup since you installed the new drive? This cleans temp/partial files that your computer accumulates but does not need.

You should also run Defragment and Optimize Drives if you haven't, this logs and organizes data so the computer can easily access it.

You said you mirrored the drive, I'm wondering if you have a bad/conflicting driver or something of the sort, did you run it as a new Windows install at all to test?
 
Thanks for your reply.

Following your advice I've run trim on the drive and deleted some files using disk cleanup. It may be a bit until I can be sure whether or not that's helped the problem with applications such as CrystalDiskInfo occasionally loading extremely slow (taking sometimes 20-30 seconds to appear after I've opened them, but usually opening quickly).

I haven't set overprovision in Samsung Magician because of the space that becomes unusable when that setting is activated. One thing to emphasize is that the drive's speeds are solid in both CrystalDiskMark and Magician when the 1GB test size setting is used. But in CDM, if I use the 64MB test size setting, the speed really drops down. Do you know if this indicates a problem with the drive? In case it's relevant the drive is only 38% full.

I haven't attempted to run the disk on nothing but a clean Windows installation. I'd have to find somewhere else to store everything currently on the drive.

I did update the firmware to the latest in Magician shortly after I got the drive.
 
It might need a restart, it helps all sorts of issues.

I am not familiar with CDM or its testing processes, it's possible (this is just a guess) that the drive isn't being fully utilized under a light load. This could be due to power plan settings for the computer or the drive itself (if that's something the 980 PRO supports).

A clean disk would help since sometimes residuals can cause performance issues (among a ton of others).

When you say applications such as CDM loading slow, do you mean more than just CDM, or only CDM?
 
Thanks again for your help.

Just one thing to clarify: CrystalDiskInfo and CrystalDiskMark are two separate programs. The former just displays the SMART info on a device's drives whereas the latter does benchmarking for drives similar to Samsung Magician.

It's CrystalDiskInfo that sometimes loads extremely slow. Another, similar application that sometimes loads in really slow is CPUID HWMonitor, which I think also has to access SMART info from my drives, as well as a lot of other system info (CPU temperatures, fan speeds, voltages, and a lot else).
 
Thank you for clarifying.

I have no experience with these programs, so I'm not sure what could really be causing this or what solutions to try aside from testing a fresh install of Windows.

Since that is a bit nuclear, it might be good to get some other opinions from the other members here, they may know something we don't.

To help the troubleshooting process, please download and run speccy.

Once you have ran speccy, please follow the instructions to upload a snapshot found here.

To publish a Speccy profile to the Web:

  1. In Speccy, click File, and then click Publish Snapshot.
  2. In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.
  3. Speccy publishes the profile and displays a second Publish Snapshot dialog box. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Thanks. Is there particular information from speccy that is needed? Looking at it it seems that it publishes quite a lot of info.
 
Speccy tells us everything about your computer and settings.

Power plans, drivers, current updates, running processes, average temps, etc.

This helps get us through some of the easy stuff without having to go back and forth.

It remains largely anonymous other than your system user profile (perhaps you named yours Doug or Greg), no one on here will ever ask you for personal information.

Furthermore, the shared links are deleted after 1 month (30 days) time as can be seen in speccy's info here:

File > Publish Snapshot. This saves your snapshot to our servers and then you can share the link to whoever you like. The person will not need to install Speccy. Note, for your security, there are a few settings that are not included in the published information, and we delete them all after 30 days.

A Speccy url unlike a Speccy txt file does not contain any sensitive information and being that we are all law abiding citizens here we have nothing to hide in any event.
 
Server migrations have deleted some previous posts.

Is this a personal machine?

Operating System
Windows 10 Enterprise 64-bit
"This evaluation software is designed for IT professionals interested in trying Windows 10 Enterprise on behalf of their organization. We do not recommend that you install this evaluation if you are not an IT professional or are not professionally managing corporate networks or devices."
 
I built the computer, the Windows installation was provided by my employer since it functions as my workstation in addition to my main personal computer (I work from home).
 
As you quoted in post #13 .. My workstation.. I am sorry as per rule 15.... 15. PCHF can not and will not offer advice for business use or financial gain. PCHF only offers assistance for personal use.
