Hello everyone - my 1st post - what a great forum

I never knew this website existed until today & changed all the electrolytics on my EPOX 8RDA3+ a couple of years ago for 105C ZL Rubycons...
However, lately, I have been having some problems with random restarts. The BIOS voltages are all withing 5% of spec, apart from one - the -12V rail, which is at -7.05V ! - Software (namely Speedfan & CPUID) both comfirm this very low voltage.

The 400W PSU is OK & has been swapped out for a new one with no changes.

I have rechecked...
