Hi guys, I have had my system running for a fair while with no issues. Yesterday I think I may have either had a power surge because the power went out for a few seconds and everything came back on except my CCTV PC. The green light still comes on on the motherboard but pressing the power but gives me nothing. I have looked into how to test the psu but everything on you tube shows how to test a 20/24 pin psu where as the hp propriety psu is only a 6 pin/4 flat pin and a 4 pin for the fan so I have nfi how to test it. My question is. Do I source a power supply from some where and go from there or should I use all my components and get a std basic mITX (h110) board to suit the i5 6500 with a normal psu and another case. I'm just guessing if I go this way then I will have to buy blue iris again and start from scratch. The only thing I would like to upgrade is the cooling as I hate how loud the thing is. My gaming PC is so much quieter. Any ideas guys?
