Hey guys, I've got a PC which gets used as my Media Center that seems to be having a problem. Before I start ripping it apart and testing various components, I'd like to get a bit of feedback as to what the problem may be.
Here are the specs, as best as I can tell them:
Mobo: Tyan Server Mobo (I don't recall the model, will have to look it up)
CPU: 2x Athlon MP 1.2 GHz
RAM: 1.25GB DDR ECC Memory (server board, remember?)
Video Card: GeForce Ti 4400 128mb
TV Tuner: Hauppage WinTV
HD: 120 GB boot disk, with 2x400gb drives in a RAID 0 configuration.
CD & DVD: Yeah, it's got those.
PSU: L&C Model LC-A350ATX (you can probably figure out the rated wattage)
Anyway, I'm thinking the weak link here may be the PSU. The case is pretty old, and I believe I got it way back when when I built my P3 700 Rig. So it's definitely an old case. The PSU has been with the case since day 1, and I think it may have up and failed, or something to that measure. The computer has not been moved, the hardware configuration has not been changed, and really nothing has been done to it prior to this happening.
Here are a few additional clues that may help with a diagnosis. Upon intially powering up, the computer stays on for about 1-2 seconds, and then shuts off (No bios beeps). While it is powered on, all fans appear to be operating normally. I cannot power the system on again until I unplug the PC, let it sit for a few seconds, and then plug it back in. (Or flip the switch on the back of the PSU for a similar duration). Now, generally this computer takes a long time to give it's happy BIOS beep (upwards of 30 seconds) but it's because of the RAM that it does this, and is not a major concern. Turning off promptly upon being turned on however, is a major concern.
I can try reseating the RAM, CPU and expansion card if you think it would help, but right now I'm suspecting the PSU. Has anyone else run into this problem or encountered this behavior before?
Thanks
