Please help me diagnose my OGXbox that is acting up.

So I have this 1.0 OGXbox and it has been FRAG'ing since coming out from being locked away in storage for a several years. I remember it working fine last time I used it. It tries to boot three times and then FRAG's 50/50 fast, does not output video, and does not output audio. I have noticed that when I press the eject button that the hard drive makes some sounds like as if it's working maybe and also the noise of the fan/fans gets louder or higher in pitch (not sure), but the FRAG'ing continues and still doesn't output video/audio. I noticed is (while having the Xbox connected to an ethernet switch) that when I press the eject button the ethernet link LED comes on for about a second or two, then goes out for about five seconds, and then comes back on and stays on. I also see the ethernet activity LED blink a seemingly healthy amount too. I'm thinking the problem is one or more of the following: EEPROM, TSOP, PSU, trace rot, maybe big shield (mildly/moderately rusted) that the motherboard sits in is not making contact with required connections on the bottom of motherboard, one or more capacitors on the motherboard possibly need replacing.

I'm kind of hesitant about putting a modchip in as I'm not sure if it may get damaged/destroyed by this particular Xbox (I have an OpenXenium on hand).

Open Xbox and remove clock capacitor and clean up around that area as best and as gently as possible with ipa 91%+.  Dry area before testing with compressed air.  Clean up av port with some ipa and q-tip/cotton swab and then dry with compressed air etc.  Check underside of motherboard for trace corrosion on point A,B,C,D.

Sounds like a classic clock capacitor leakage scenario. Best to open it up and check for busted caps. If there are some others besides the clock cap, then you need to replace them. 

Edit: The clock capacitor does not need to be replaced. Leakage can cause traces underneath the board to rot which causes FRAG.
