If you want to revive it you'll probably have to get windows or whatever system your pc was running off of and the virus still might be able to get in to your new copy of whatever you bought. You can either get it looked at or sell it off for parts.
If you formatted twice, then installed an OS, I'd place the odds of recovering anything usefull at less than 5%. I can pretty much guarantee you that no consumer grade recovery tool will do the job, and in all likelyhood will render what might have been recoverable by professional methods forever lost. Even a forensic recovery service can't guarantee recovery and will cost $$$$ if you wish them to make the effort.
