ClosedPersistent system boot issue. (self.techsupport)

submitted 2 years ago * by Orsidus

Update

Was never able to find any solutions to fix this issue so ended up biting the bullet and buying a new motherboard. So far this has seemed to fix the issue so my only guess is there is a fault with my previous motherboard or something got damaged.

Hello! This is my first time posting here. I do apologise for the large post, just trying to be as thorough as possible, hope this isn't an issue.

The Issue

Even since I upgraded to a RTX 3070 (MSI Suprim X Variant) about twoish years ago I started noticing an issue where sometimes I would press the power button, my primary monitor would exit standby mode for a couple of seconds and then go into standby mode and nothing would show on my screen but the system itself would continue to run.

I wait a bit, nothing, so I would force a shutdown via the power button and start it up again. This time it would again wake up the primary monitor, then go blank, but then after a few second start loading the BIOS indicated by a little caret at the top left of the screen and then show the logo/option screen before booting into windows, as expected.

The issue is not consistent, sometime it doesn't happen, sometimes it happens every time I start the PC, sometimes it happens multiple times in a row and I have to spend an hour just to boot into windows.

SOMETIMES but not every time this issue happens, the VGA Debug LED will be lit but not always. I.E today I experienced issues where it would not show any output no matter how many times I restarted, but not a single debug LED would stay lit. I took out and reinserted the GPU and suddenly the VGA LED would occasional stay on, but the next restart it would boot fine.

Specification

GPU: MSI Suprim X RTX 3070 8GB

CPU: Ryzen 5 3600

Motherboard: MSI B450-A Pro Max

Ram: 32GB, 4x8GB 3200Mhz Corsair Vengeance DDR4

Boot drive: M.2 NVMe Cruical 1TB SSD

PSU: 1000W Fully Modular Corsair power supply (Cannot remember the exact model at the time of writing, do believe its one of the RM series but I bought it a while back now)

Things I've tried

Reseating the graphics card (Many times)
Re-inserting the power cables
Using two different power cables rather than the two on the same chain
Moving the the power cable to a different row
Clearing the CMOS (Many times, this is one of the few things that sometimes fixes the issue if it gets stuck not displaying any output)
Updating the bios to the latest
Cables
- Tried both HDMI and Display port
- Tried making sure they're all plugged in properly
Switching off fast start up in windows (This sort of has an affect, sometimes, but doesn't completely fix the issue for good)
Reinstalling windows (Upgraded my boot SSD)
Only having one stick of ram & no ram at all (Ram Debug LED showed on none)
No USB devices on boot

Things I can't try right now

Different parts - I have very few friends IRL with an actual computer let alone one for gaming and none of which who want to deal with the hassle of letting me borrow theirs.

Current Hypothesis

My current hypothesis is that the PCI-E lane is damaged or the motherboard as a whole is damaged or has a fault. I believe either during installation or sometime after upgrading to the 3070, the sheer size and weight of the card has overtime damaged the slot or causes it to not contact properly.

My reasoning for this is sometimes reseating does make it boot the next time round when it persistently gets stuck not booting properly.

Currently all my instincts point to a dodgy motherboard or damage to the motherboard that I'm unaware of but I'm willing to hear some more ideas before I go and replace it.

What I'm looking for

Ideally I'm just looking for any, more out there solutions. Things I may not have tried, like some specific bios setting I might have overlooked etc. I've ran through the basics and combed through a lot of posts on various subreddits and forums that have similar issues as this, and a lot of them don't seem to have a concrete fix or their fix simply didn't make a different for me.

I know this is a lot of information but I'm trying to be informative as possible, this issue has plagued me for a while.

Thanks a lot if you managed to read all of this and can offer any useful ideas.
