Bit rot.

Hard drives (and all other forms of storage and memory) are constantly suffering errors, as a natural result of pushing the physical boundaries of what electrons can do. All drives, optical media, etc feature parity correction that attempts to detect and correct these errors. Parity can fail, though, and it's not always possible to figure out which bit is bad or what to do about it. These problems can be exacerbated by a variety of environmental factors, as well as bugs in the underlying platform. Your hard drive has hardware and software components. So does the motherboard. These can all fail in highly creative, undetectable ways. As a hard drive begins to fail, the uncorrectable error rate can spike, and checking SMART may be a good idea. Some file systems, notably ZFS, BtrFS, and ReFS are designed to handle these problems in more robust ways.

Alternatively, any random component (hardware or software) of your system may be malfunctioning, or you may have some type of malware. Good luck finding out what the source of the problem is.

Fraps did not break your computer.

Ok back. What about in the file revisions it said it was modified yesterday and for some reason the folder was set to shared as well yesterday at 7.51Am.

but When I checked to day its not shared ???? this is alarm bell to me not hard drive.

In fact I have a hard drive that is 20 years old working fine and Ive had like 25 years worth of computers and never had a hard drive fail.

I could go in the back room and start my very firts computer a IBM aptiva 166 heehehe(third Computer).

That's understandable. The first time a drive fails on someone they are confused and don't want to believe it could've happened to them, it's a distressing experience, especially since hard drive failures can often be more subtle and insidious than "cannot find boot sector". If you didn't have backups, having this happen to you is one way to get the point driven home (the hard way).

So can hard drive fail write a modified log.

Sure, why not. Where do you think the log is stored?

there was a unknow app in system configurations on startup some thing going by the name language_Application no install date its gone now.

This just means you are biased because you suspect a hacker has infliltrated your PC, so every little thing will look like a red flag to you. Be careful of cognitive bias when trying to draw logical conclusions from events you are emotionally connected to (and you obviously are in this case, given your reaction). You say you have backups, so use them:

1. Nuke your PC and reinstall the operating system (to alleviate your - irrational - fear of hackers)

2. Run hard drive tests and replace the drive if bad

3. Restore all files from backup

4. Resume normal life

This shouldn't take more than about a day, spent mostly reinstalling software.

Besides, let's assume for a second that your doubts are justified and this is the result of malice. If your computer really was targeted by someone, don't you think he'd have better things to do than randomly corrupt a file you haven't opened in years? Wouldn't he just go for your source code, erase his tracks as discreetly as possible, and then boast loudly about it on the internet? Very little malware is specifically targeted, and it always is targeted at high-profile entities like terrorists, nuclear facilities, or high-ranking officials (we call them APT's for advanced persistent threat). Most of the stuff you'll get on an average consumer PC is spyware and generic trojans that just scan for passwords, email addresses, credit card numbers, and use your residential line to send spam email as part of a botnet. They are nearly fully automated. They certainly don't search for game source code, and there is no-one at the other end trolling you by flipping bits on your hard drive

I'm not saying it's guaranteed to be a hard drive failure, just that given the choice between that and a hacker stealing your source code, I would certainly find the hard drive failure a more likely explanation. But like Promit said, there could be many other causes, none of which can be remotely diagnosed. So try to relax - you (probably) aren't under attack, investigate the problem, but keep your expectations real. The causes of your malfunctions probably are much more mundane than what you're picturing them to be.

In fact I have a hard drive that is 20 years old working fine and Ive had like 25 years worth of computers and never had a hard drive fail.

I have a car that has never broken down and has never been in an accident. None of the other two cars I have owned have broken down or been in an accident either, and out of all of the cars my immediate family have owned only one has ever broken down and none have been in an accident.

This has absolutely no bearing on the fact that thousands of cars break down and thousands of cars are involved in accidents every day.

The fact that none of your previous hard drives have failed -- if that is in fact even true, considering that some of them may be gradually failing and you simply haven't noticed the problems yet -- does not mean that your current hard drive is not failing.

You've asked what the problem might be, and numerous very knowledgeable people have told you that the most likely cause is drive failure.

If it isn't drive failure -- and again, that is the most likely cause -- it's far more likely that some malware is making completely random changes rather than someone specifically "attacking" your unknown game.

You've also been told how to proceed with both diagnosing and recovering from the most likely problem -- rather than worrying about an extremely unlikely problem it would be most productive for you to proceed with those steps -- especially given doing so would also help in the extremely unlikely event that a hacker is specifically targeting your game.
