I hope this is the right place for this topic. My son re-booted his computer yesterday and ever since, it'll go through the POST but when it comes time to boot into Windows, there's a beep and it's back to the start and POST. He apparently hasn't installed anything lately or noticed anything unusual. I tried sneaking into Safe Mode, but it won't boot into anything. For what it's worth, the PC is less than a year old and it has XP on it. Any ideas on where to go with this would be appreciated.
