Shuttle has been working fine for about 4 years. Then it would be slow coming on, maybe boot up 20 mins after pressing the on button. Eventually refused to come on at all. I replaced the power supply and wow starts up beautifully but only when you press the reset button. Power on button now reduntant. Works great for 4 weeks then won't come on at all. I have looked inside and there is a green LED on - no other lights, also when you first apply power the video card fan turns for about 4 seconds

Change your BIOS battery.
I have an old Shuttle XPC sn41g2. It's been running almost constantly since it was new. About a year ago it started to be difficult, it was difficult to start and sometimes I had to try several times before it started. At the end I had to disconnect and reconnect the mains supply everytime i had to reboot the PC. Then one day I discovered that the prosessor was running at the lowest standard frequency so I went to the BIOS to set it right, did so and rebooted, and the prosessor stil wouldn't run right. After some thought I changed the BIOS battery, went to the BIOS, resat all settings, then it rebooted normally and since it has been running like new.
Is the inside of the machine clean? How long since the CPU heat sink has been removed and cleaned off? Same question regarding the video card. Difficult to evaluate without seeing first hand, but being 4 years old, that is where I would start.
