Have a htpc with Hauppauge HVR-5500 TV card. 1 front case fan. Bluray drive and m.2 ssd and 4TB storage drive. Asus H97i-plus motherboard and i5-4690 cpu. Silverstone 300 watt powersupply. Tonight watching the Rock and computer suddenly shut down. Unplugged power cord. Left for half hour turned on but wont start. The power light slow flashes like in standby and all fans are spinning. Just wont start. Anyone seen this. Will look at it tomorrow but just wondering if anyone had a heads up. System 6 months old apart from cpu all parts new. Have an old power supply I can try tomorrow but not suitable for case but should tell me if thats the problem.
