Motherboard: Intel H61 Acer Aspire M3920 (7 years)
CPU: Intel Core i5 2300 ( 7 years )
CPU Cooler: Cooler Master Hyper 212 Turbo Red (5 months)
CPU Thermal Paste: Cooler Master MasterGel Pro (5 months)
Graphics Card: Zotac GTX 1060 ( about 1 year)
HDD 1 System: WD Blue 1TB (2 years)
HDD 2: Hitachi 250GB
Operating system: Windows 10
RAM: 2x 4GB Kingston 1333Mhz ( 3 years)
PSU: 700W Silverstone Strider Essential 80plus Bronze ST70F-ESB (less than 1 year)
So basically the PC is roughly about 7 years old and I've changed a lot of parts except for the motherboard and CPU. However, recently my PC has been randomly shutting off at unexpected times even when just idling. Now the PC switches off before booting and even while on the bios screen. I believe that the PSU might be to blame because there were some buzzing sounds from it which I'm not too sure if its normal or not. I need some advice on how to isolate the issue but I don't have another PC to test with so I'd appreciate some ideas which don't require another PC to test with. Thanks.
