Are you absolutely sure that it's 'HPCELE.exe'. It's unusual to find a process name that Google denies even exists.
At a guess, something starting with 'HP' is likely to be something that arrived on your computer when you installed a printer (or other device manufactured by HP). Removing that software and reinstalling it might fix the problem but, since I've no idea what the program actually is, it's hard to be sure.
Further, it's not clear from your whether you get the 'blue screen of death' as soon as you start up your computer or whether it only occurs later. If it's the former it could be hard to fix the problem because you can't get into Windows. If it's the latter it might be simpler.
If nobody posts a solution to your problem, try entering Windows Safe Mode (by pressing F8 during the startup process and selecting 'Safe Mode' from the options available to you). Then run System Restore (from Start > Programs > Accessories > System Tools) to take your computer's registry back to the most recent available date when everything was working normally. (That, of course, assumes that you can actually get into Windows Safe Mode to start with. If you can't get past a blue screen you'll probably need a computer technician's direct help).
