Hello all,

PC has been working fine since it was built in Jan but has recently started randomly BSOD / freezing during or shortly after start up.

If I shut down normally then turn it on again, everything is fine even after a 3-4 days of no use.

If I shut it down, then turn it off at the PSU or mains at any point afterwards, then the next time I turn it on it will either freeze on boot or will semi crash about 15 mins into usage even if left idle.

The reason I say semi crash is because it just freezes, sometimes the screen will turn off and the peripherals like keyboard and mouse will turn off, but all fans will continue to run or it will just BSOD.
Sometimes I get hardware failure warnings other it does a clean restart. It's behaviour is really inconsistent.

Evetime this happens I cannot turn it off using the case switch, only by turning the PSU and mains which means next time it starts, it happens all over again.

When I do get past boot, I do a normal restart and everything is fine again.

It seems to have coincided with the last Windows update I did, but I have no proof that it's the cause and haven't seen other users report the same behaviour after updating so it could just be coincidence.

Sorry if this seems like a ramble, it's an odd one to try explain.

PC Specs should be in my signature below.
