Can't even get into safe mode by holding down the F8 key? And it doesn't say what resource vfat is looking for, I suppose. Makes for pretty slim clues.
These problems are usually caused by one of two things, disk failure, bad sectors, or by malware. We can at least narrow it down by running scandisk in ms-dos mode. Hold down the F8 key during boot up, not to soon or it might say keyboard failure, and when the selection screen comes up choose 5, DOS mode only. When the command prompt comes up just type in scandisk and hit Enter. After the first series of scans it will ask if you want a thorough scan. Accept it.
It will also give you a nice graphic display of where any problems are on the disk. If there are several bad sectors, specially near the start of the disk, that is likely the problem. If you get a clean bill of health, the other possibility needs to be looked at.
It takes a bit of time but it may save you from trying to fix the unfixable.
