After some recent additions to my htpc, it has started shutting down. I have only seen it once, and it didn't just die, windows shut down. It has shut down several other times but I haven't seen it. My wife claims to have seen it just die, but her computer knowledge is low, and she may have missed something. At least twice, I was in the kitchen, and when a video ended (played through nero showtime), the computer shut down. I cannot get it to do it in front of me though.
I installed another hard drive (making it 8 hard drives).
I installed an antec basic veris remote control (which does have the power switch from the case going to it and then to the motherboard), and I have not installed the software for it yet. I have seen part of a few shut downs (I was in another room, a show ended, and the computer shut down). I thought that the remote unit might be shutting it down after a show but when watching it, it doesn't happen.
I installed an internal card reader. I cannot see how it would cause it.
I have 3 pci slot fans and one has started making noise (like a wire was hitting the fan intermittently, but there are no wires to hit it). It is almost touching the back of the video card. Maybe its shorted out.
the power supply might be too small and the extra hard drive pushed it over the limit. I also put a different optical and maybe it requires more power. The label side is not exposed so I'm not sure what power supply is in it, but it is an antec, and it is at least a true power 430 watt (the original true power's, but I got it old stock cheap, and it sat on the shelf for a while, so it has less than 2 years actual use). It might also be an antec basic 500 watt.
Tonight I saw something weird. I turned on the microwave, the lights dimmed, and it shut down. The wife says that this has happened other times when the microwave is used over the past few days since I worked on it. Thing is, it is connected to a ups, and it shut down, but 2 other computers that are connected to the same ups, did not shut down. Maybe the power supply is so overtaxed, that it cannot handle when the ups switches to battery?
Anyone got any clues? Its not heat. Its an antec 900 case with 3 120mm, 3 pci slot fans and a 200mm fan. All hard drives have some sort of fan. I have checked all temps in software, and one of the hard drives is mounted in a temp sensor/cooler, that reads the drive temp and a remote temp. Nothing is hot. The wires are a massive pile of crap, but there is enough air to deal with it.
I already have an antec true power trio 550 watt that I am going to install (in case it is the power supply), and if I can figure a way (with the 900 case), I want to run custom wireing, something like I did with my plus view case
but I'm not sure where I'm going to fit it yet?
Anyone got some guesses as to where the problem really lies (there is a lot of trouble shooting to do, and there are so many wires, if I touch anything, a few cables get pulled out, usually sata cables). I'm working on a plan with the wires (with any luck, I'll find room for custom power wiring but there's not much more I can do with ide drives than round cables).
As far as spec and the power supply, its an athlon (single core) 64 3400, abit ax8 motherboard which is not currently overclocked (I think, I guess I should check, but the heat sink is ample and temps are good). It has 2 gig of memory (again, not sure what, I cannot get past the wires to look, but its 4 sticks, most likely unmatched Kingston sticks). vid card is a shaphire 2600 pro. sound card is sound blaster (no idea, most likely an x-fi audio).
