Hi
Sinds last week I'm experiencing a weird thing with my PC system...
My PC wont turn on the normal way. I have to switch off and on my PSU power switch in order to boot my PC? First I thought it was a 1time issue but now I have to do it every single time...?
It's a Corsair RM850.

I've searched the forums and read topic
"PC only turns on when PSU switch is turned off then on again." I'm sorry but is it really a PSU issue??

Next thing is, when my PC boots, it displays 2 out of 3 of my HDs (SSDs), but my 1TB HDD doesn't show up at all. Not even in Disk Manager... So I need to reboot my PC so that it will be mounted.

Anyone has any advice?

Thanks in advance
 
Solution
Since you are having issued with the drives, unplug from power and SATA ports all drives except the boot one, does the system boot OK then? If not, then it could be the power supply. Maybe a motherboard issue or a case connection issue.
