Potential Motherboard Fault?

Hi All,

Recently I've been having issue with a self-built PC, which has been running fine for about 3 years. In the past couple of weeks it has been having OS corruption issues for reasons I can't seem to pin down.

I've freshly reinstalled Windows 10 from an official ISO, I've swapped out the RAM for new sticks and replaced the HDD (with another fresh install of Windows 10). After a few days, the system becomes unstable, boots into disk repair and crashes on booting. It's fine again for a little while after a reinstall of Windows.

Here are a few steps I've taken, in summary:

Reinstalled Windows 10.
Updated GPU drivers.
Rolled back GPU drivers.
Tried a different GPU.
Installed new HDD with Windows 10 installed.
Installed new RAM and removed old RAM.
Run copious disk checks/fixes using chkdsk.

After trying all of this I can't figure out what could be wrong. When running, the system is stable and this issue just comes from nowhere. I'm wondering if it could actually be the MoBo causing this? Bad contacts, damaged SATA ports, etc? I've never really experienced issues with a damaged motherboard.

Thanks for any suggestions and advice in advance.

I'd say quite trustworthy. I've used the same PSU in a few builds and never had one fail on me. However, now that you mention it, there's an outside factor that could affect it.

We've just moved house, and in the previous house our electricity was metred, so would disconnect when the credit ran out. I suppose it's feasible that the sudden loss of power due to this can damage the PSU? This is the only PC in the house that is affected by this issue, though. Other PCs in the house were often in sleep or hibernate mode when this happened and there have been no adverse effects.

Thanks for the fast response.

The PSU doesn't have a voltage selector, only the on/off switch. When I said "the same PSU", I meant the same brand, but new PSUs for different builds. Sorry for the miscommunication there, didn't realise it was unclear.

I don't think a brownout is likely, the electrics in the house are well looked after and the local area doesn't suffer from them. I will see about checking the socket when I get home though.

The old HDD was clicking (likely a slipped header during the move), which is what I thought the problem was initially. After multiple failed chkdsk /f /r attempts, I bought a brand new Seagate HDD. The forced disk checks on Windows rebooting always finish quickly and find no bad sectors or issues.

Update: I switched out the PSU for a new one and tested the wall socket, everything is okay in that area.

Again, reinstalled with a freshly burned Windows ISO. The issue is persisting. After running for a while, the system freezes up, no sound, image stays still, but no shutdown happens. I don't have to be doing anything in particular to make this happen, but the PC is somewhat usable aside from this.

I'm happy to try both solutions, but what is more likely in this case? Damaged or overheating graphics card, or damaged motherboard?

Thanks.
