This started after trying to enter password recovery mode and rebooting. It rebooted the one time and started to load the ios but had some sort of TraceBack/Exception on the screen. I reset the power to try it again and it got stuck in this state. The power and fans come on but no output to the console port. I am getting a solid orange sys light and a solid green activity light. After about 5 minutes it then reboots automatically.
I am getting no output at all on the console line, is the hardware toast? Is there a way to force a reset on the device?
No Cisco support and the warranty is up. 🙁
Edit: I have let it sit for a few days and came back to it. Not it turns on and just dumps this data out. The program exception just repeats itself forever until it powers off and back on again.

Couldn't get anywhere after that so I rebooted it and now I am back to the beginning where it won't even output anything to the console.

Appears there is no physical compactflash module in slot 0, appears to have on in slot 1 with at a minimum a corrupted file system and at a max bad physical flash as you are getting file system sector error and the storage areas are corrupted. Can't write the crashdump file and that is why you get the repeated reboots after 5 minutes. If control break is enabled then after the first few seconds after power on you can hit control break and dump out to the rommon prompt: May have to type flash_init to activate the file system, type set to see where it is pointing to for the ios file then type dir flash1: and see if it can read the file system. If you have access to the ios from either a backup or from another 3925 copy it to a usb stick and put in the usb flash slots if your model has them. I believe it does. I try and use 1gb sticks and smaller. Not all Cisco routers will accept the larger sticks. From the rommon prompt: type usbflash0 or 1 depending on which slot you put it in and see if the router can see the stick and the files. If so you can boot off of the usb stick. prompt: boot usbflash0:file name and hit return. If the rest of the router hardware is good then it will boot up without a config. May get a few errors go by because the rommon set is pointing to the bad flash for the config and license file but will come up if hardware is good. Best you can hope for at that point. You may be able to reformat the flash file system. If you have licensed any features when the router was purchased you will need the license file to turn on more than the base default license. Definitely either corrupted file system or bad flash.
