Probably not. One of the actual "features" of System Restore is that it does
not affect personal data files. As it's name implies, System Restore is designed to restore the "system" back to a previous state without affecting anything else. So, for example, if you updated a system/hardware driver that was faulty, you could restore the system back to old drivers. Or if you updated system files, you could roll them back too. Imagine how upsetting it would be if you spend many hours or even days updating an important Word document or Excel spreadsheet then you ran System Restore only to discover you just lost those days worth of data. So System Restore, by purposeful design, does not affect user data files.
You could try a file recovery program like
Recuva from the makers of CCleaner.
Wise Data Recovery is also popular.
Of course, hindsight is, or should be 20/20. A good backup plan would have made this easy.
And I would be remiss if I did not point out XP needs to go away. Microsoft gave users well over
5 years notice support for XP was going away and it has been over 4 years since that support ended in April 2014. Nine years is plenty long for those even on the tightest budgets to migrate to a safe, secure alternative.
Please understand the problem is
not that you are putting yourself at risk. The problem is when this computer connects to a network with Internet access, it becomes a threat to the rest of us! And that is just not cool, or being a responsible netizen.
Bad guys are actively seeking out and targeting XP systems to compromise and infect. They then use those systems to distribute malware and spam, and/or to draft into their bot-armies as zombies in DDoS attacks on others - all without the user being aware their computer has been infected.
I note refurbished or off-lease system with modern operating systems can be had for a song. Check out
Walmart refurbished computers. If replacing this computer is still not in the budget, I would urge you to install and use one of the many free Linux versions instead. At the very least, disconnect this computer from Internet access and use it as a stand-alone system. Bottom line, XP needs to go away!
Last, it should be understood BSODs are often signs of impending hardware failure. Considering that computer came out in 2003, a 15 year run has already beaten the odds. Its had a remarkable run!
