Random reboots

[Penfold7]

Thanks. It’s learning for me is this, never seen 2 CPU pwr connection. I’m used to the 4pin ones…

[Penfold7]

Hi. Apologies for more questions. It’s really been an education as this for me having not built a pc for a number of years… The manual doesn’t state if one or both CPU pwr need connecting so if no issues will connect both. With regards to reinstall windows, should I install as legacy or UEFI. If UEFI is there a special way of downloading the windows installation files or will the standard files detect it’s set to UEFI, or do I get a choice at initial boot. Would using Rufus to create a bootable usb be better. Currently boot devices are set to UEFI+legacy. Should change this before I install to UEFI. Again sorry for probably simple questions

Also due to sudden work commitments cannot do most of this till the weekend :cry:

Oddly A-XMP is disabled in the bios, but when I’ve rebooted cpu-z says it is using xmp 2.0 profile. His mate keeps telling him to run the system in safe mode to see if it still reboots. I’m not sure safe mode will tell us anything. Any ideas

[Penfold7]

Not sure it it makes any odds but manual states memory should be in DIMM a2 and B2. It’s in DIMM A1 and b1. I feel I just need to pull everything to bits reinstall the lot as per the manual and fresh install windows …

As was previously explained the four pin 12V ATX is for extreme overclockers so you only need to have the eight pin connected, the four pin connector should be secured so that it cannot come into contact with any part of the MB or chassis etc.

Windows should be downloaded directly from Microsoft and myself personally always install in Legacy as it is less problematic.

Safe Mode will do nothing to change the fact that the RAM is in the wrong slots or the RAM being the wrong spec meaning that XMP cannot be enabled.

Ram should normally be in A2 and B2.

I feel I just need to pull everything to bits reinstall the lot as per the manual and fresh install windows …

Why not, you will only be doing what should have been done in any event.

Thanks, I’m really appreciative of your time. Any ideas why CPU z is reporting xmp 2.0 enabled, but in bios it’s Def disabled. It can be enabled in bios though. Hopefully come sat, after I’ve pulled it all apart, given it a good clean put back together and reinstalled windows all will be well.

No worries (y)

Any ideas why CPU z is reporting xmp 2.0 enabled, but in bios

All users BIOS settings/profiles should be deleted when the MBs default factory settings are restored

Has the below been done yet.

Restore the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" “most stable” or on newer boards “optimized” please note that if you have both the “most stable” and the “optimized” options in the BIOS you should choose the most stable" option as in this instance the “optimized” settings are a form of overclocking that can cause instability.

Save the new settings, exit the BIOS, restart the computer and XMP will be d

Unfortunately not, as said unfortunately work commitments have got in the way. I’ve pencilled in Saturday to sort it all out.

[phillpower2]

Explains why the XMP 2.0 profile is still present.

No response from the OP;

To avoid us having to ask for an update every couple of days we will close this thread until the OP has the time available to work towards resolving the issue, PM a member of staff when you are ready and the thread can be reopened.

Hi
Adding this (If needed can a Mod merge with the original thread) @phillpower2
So finally managed to get all of this done, with work commitments and having to go away getting in the way.

I pulled the Mobo out of the case, glad I did as the wrong screws had been used and I could pull them out with my fingers!!. Removed and reseated everything. Put back into the case with correct motherboard screws and put it all back together.
Updated BIOS to the most recent version, as it was woefully out of date, and reset BIOS to the default values.
Reinstalled Windows as per instructions in previous thread to the letter.
Updated Windows

During the Windows update it started to randomly reboot again, with the same error message in Event viewer

WHEA Logger
Event ID 18
A Fatal hardware Error has occured.
Processor APIC ID 8
Error type Cache Hierarchy Error

Im a bit stumped now. i was going to start in Safe mode, but as its a completely fresh install and it started doing it when nothing really apart from Windows and the GPU drivers had been installed, not sure what this would tell me.

Im suspecting a Hardware problem, but has anyone any other ideas or troubleshooting steps to perform?

So the entire 20 minutes (or so) installation process went smoothly and it only started rebooting when you were doing the Windows Updates part?

If so, where in that timeline were you; so Win install, reboot, chipset drivers install, Win updates…?

[Bruce]

reply from Penfold7
Windows installation went fine. Ethernet disconnected.
Installed chipset drivers, GPU driver’s and audio drivers
Connected to internet and started windows updates. During the cumulative update to windows 10, during this installation reboots started. I was concerned we were getting stuck in a reboot loop but the install eventually took.
Exactly the same issues as previously

What GPU driver are you using - Do you have a link?
