I've got a Vista Media Center PC, it's about 5 years old and has been running in the living room pretty much constantly. For specs, it's got I think an old AMD64 processor, a DVDROM, a 20GB IDE drive for the OS and a 300GB IDE drive for the recordings. There's also a dual tuner Hauppage card and I think an old FX5200 video card. The PSU is a Silverstone 360W model. It's been running like a champ as long as I remember.
We use it a lot. Sometime a few days ago it apparently shut off; when I try and power it on it powers up for a split second and then shuts right off again.
I opened it up and started trying to diagnose the problem. I narrowed it down to the 300GB drive. If I disconnected it, the whole thing would boot up normal. But as soon as I connected the drive to power it would instantly shut off after trying to start it up. I tried different power plugs on the same PSU with the same result.
I took the drive out, ran checkdisk on it on another PC (the other PC booted just fine with that drive as a slave) and it came up clean. But I was back to my original problem as soon as I tried to add the drive back into the original HTPC.
I want to say it's a power supply problem, but wouldn't I see other problems, or it wouldn't power up at all no matter what? Is the second drive drawing that much power that it would make the difference? Could the PSU be "going" and it's just a matter of time until it dies altogether? Is there something else I may have missed or should try? I'm probably looking at building a new HTPC altogether, but if I could get a new power supply in the meantime to limp along I'd look at that. The drive seems fine - but could that be causing a problem?
Thanks for any help or advice!
