99.9% sure it is not a hw problem nor is it your IOS version.
If flash is not being loaded or is crashing during load, you might have to
If flash is loaded and an attempt is made to load the config file from NVRAM
and it crashes, then I suggest you go into ROMMON> and erase your NVRAM and
reload. This has fixed the same problem for me in the past. The problem
usually lies in a file being corrupted during a power down.
If you need more assistance, please respond directly.

So I take it you cannot load the IOS in the flash? Have you tried getting
into ROMMON> by breaking the boot? That may help decipher where the
problem lies. It may be the pre-boot flash (I think the Ciscos have a
shrunken bootflash and then a full size IOS image in flash).
