Frequent reboots since upgrading hardware (new MOBO, CPU, RAM, SSD)

About two months ago, I upgraded my system (new MOBO, RAM, CPU, SSD) and also installed a fresh copy of Win10 Home Edition. Shortly thereafter, I've had a recurring problem with my PC just randomly rebooting. It can be while I'm actively doing something or when I'm away. It seems to have gotten much worse the last few days. Here's the troubleshooting I've done so far:

Disabled (unchecked) the "Automatically Restart" option.

Under "Processor power management", I set the minimum processor state to 5% and "Allow hybrid sleep" to off.

Ran cleanupmgr, sfc /scannow

Disabled Windows 10 virus software (I'm running Malwarebytes instead).

Ran the following services:

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

Yesterday, I started the process of eliminating memory. I'm running four sticks of Corsair memory (8Gb each).

The slots on my MOBO are labeled DIMMB2, DIMMB1, DIMMA2 AND DIMMA1 (going from the slot farthest from the CPU to the slot closest to it).

Using the user guide, I pulled all the sticks but one, leaving it in slot DIMMA2 (which is what the doc says to use for a single stick).

Rebooted the PC and when it got to the login window, within about 5-10 seconds, it rebooted again. Threw a different stick in the same slot. Same problem.

Put a different stick into just slot DIMMB2. It ran for several hours but in the end, it rebooted again. I just moved that same stick to DIMMB1. Rebooted while actively using the PC. I just now put a different stick into DIMMA1 (since I've already had two different sticks in DIMMA2).


I'll continue testing all sticks/all slots, but I'm beginning to believe it's not the memory. So, while I'm working through the remaining memory sticks and slots, I'd like to know what else I can be looking at. Any help is appreciated.

MSI Pro Z690-P DDR4 LGA 1700 ATX

Intel Core i5-12400 2.5Ghz 6-core LGA 1700

Vengeance LPX DDR4 DRAM 3200MHz C16 Memory (four 8Gb sticks)

Windows 10 Home Edition

Crucial 1Tb SSD MX500


Thanks,

I had the same reboot problem when I was running Win 7 64 bit pro. I did a Win 10 'upgrade' action where it upgraded (replaced) Win 7 to Win 10.

One of the things that moved me to WIn 10 sooner rather than later was the Win 7 box would reboot at unpredicatble intervals. I did the same RAM/SFC /scannow, DISM, etc that you did without any success. It also had a habit of locking up for a minute or two and then picking up where it left off like nothing happened. I spent several months trying to chase it down in both Win 7 and 10. To my dismay, both of those problems continued after the upgrade. After doing the same troubleshooting again, I gave up and did a clean install on an empty, formatted drive. Problem solved. Conclusion? One of the Win 7 drivers that wasn't replaced during the upgrade was the problem.

One more thing...I've encountered multiple instances where Windows update replaced drivers and my computer wouldn't boot! I've had to do a roll back 4-5 times in the past few years, most notably on my laptop. I'm guessing Microsoft engineers are not fully up to speed on some of the drivers they've written. So now, I refuse to update any device drivers amd use WUMGR to put an end to it.

I'm also thinking that your problem might be power supply issues. If not that, then device drivers. So, I'd first reinstall all drivers from the CD that came with your mobo as well as video card, etc. It didn't work for me, but it's worth a try.

While it's unlikely that the power supply is failing, if you could borrow a larger wattage PS and the rebooting is gone, that's the problem. It doesn't need to be screwed into the case...merely sitting on a box with the wires going into the case works fine. Perhaps your power supply is simply overheating. Too much dust in the grille/filter? For what it's worth, my current overclocked AMD 3800x has 2 140mm fans and 2 200mm fans, all blowing into the case. The only 'exhaust' is the three 140mm fan radiator for my liquid cooler. An easy way to check overheating is to run the computer with the side(s) off and a small 110v fan blowing air into it. If the problem goes away, you found the culprit!

Thanks for all that info bratkinson. I did do a clean install of Windows 10 when I upgraded my system (since I was going from an old HDD to SSD).

I forgot to mention this earlier, but I did look for any device drivers or BIOS upgrades for my MOBO and none were available at that time (that was only a month ago). I think I'll look at device manager and see if there are any that can be upgraded.

What exactly is WUMGR?

After I posted this, I did come across a video where they mentioned the PS could be the issue. But, I've been using this same PS for at least 5 years with no issues (it's a 750W Corsair PS). I have a spare, but I'm going to hold off on that for a bit.

I don't think it's a heat issue, as every time it's rebooted today, I've shut it down and put another of my four RAM sticks in the same slot (the one MSI recommends to use if just running one stick of memory) and it never felt hot at all. I don't overclock or play games on it. The video card is built into the CPU.

thanks,

Andy

WuMgr is a free Windows Update manager. Google it to find out. It's a great way to control when to update as well as only apply specific updates. It can also be used to 'lock out' the update from happening. Take a look at AskWoody.com and their MS-Defcon level to know when to update.

Could it be the power supply is overheating? In my current case, the air intake is on the bottom of the machine and there's a removable mesh screen over the opening to trap dust. Dust is a real problem even though I have the computer sitting on top of a couple of left over floor tiles to protect it from the carpeting. I still have to clean the mesh screen every now and then, just to be safe.

Hi!
Here is what I would do:
I would boot my system into a Linux distro from a usb stick or dvd.
I often use Kali cos it is for my job.
if it boot up, I would go to youtube and just play something for a long period of time ( several hours ).
Cos I constantly use Kali I would also do other tasks on that pc.
Maybe I would also try some stress test apps during the Linux is booted.

If the PC survive then it is probably not a hardware level problem.

I hope you got my idea.

I'm going to install WUMGR. That sounds like a good utility program to have. Thanks for that.

I had multiple reboots yesterday and was placing my four memory sticks into slot A2 of the MOBO. Regardless of which stick was in that slot, it still rebooted. So I think I can safely rule out memory.

I don't believe it's the PSU, as each time it shutdown and I was moving the next memory stick into slot A2, the inside of the case didn't feel even warm, nor did the PSU. HOWEVER, I do have a spare Corsair 750W PSU (like the one that's installed) and just swapped it out. I'll report back what happens.

EOF, that's a good idea. If the PC keeps rebooting with the new PSU, I'll give that a go. I know exactly what you're talking about. Thanks for that tip.

pepannee - I had done that when I first started tshooting and it didn't help at all. There was nothing in at the time of the reboots.

UPDATE:

I replaced the PSU I had in my PC with a new/spare PSU (same exact model). It has NOT rebooted once and it's been almost 10 hours now. I'm hopeful, but waiting a couple of days just to confirm. I'll report back at that point.

You can use a tester on the power supply to check it. Make sure 3v is 3v not 2.6 or 3.4, same with the 12v and 5v lines.

Hmmmm...
I wouldn't mess to much with these psu testers. They are not reliable, especially if you use them on a psu without load...
Take care with the results of the testers.
I'm working as sys.admin in several companies and we have many of these testers and we had lot of false alarm ot even not detected bad psu by the testers.
