The situation isn't really clear from your post.
- A reboot loop seems something that happens continually: you turn it on, it boots, it gets to some point in the startup sequence (say the welcome screen or your desktop if it's set to autologin), it shuts down immediately, it reboots, etcetera.
- But 'it came back on Sunday' seems that it was turned off for three days and worked immediately when you turned it on.
So please tell more about what happens exactly if you turn the machine on. Also tell what happens if you press f8 at the right time to come into the Windows boot option menu. Just saying "the crap doesn't work" isn't very informative, while we need all information you can give to give the best possible opinion and advice.
It's doubtful if you can repair this without XP cd. Why don't you have one? And what alternatives do you have (system recovery disks, system recovery partition, use a friends CD)?
Of course, you won't lose any data as long the hard disk is still fine, because there are several ways to get all your data safely off it to an external hard disk (even safer: from that external disk to another PC, so you have 2 backup copies).
If, however, the hard disk is damaged you'll only use the data you didn't yet backup. For most people, that's a week of data at most. Some unlucky people didn't backup at all and lose all. But that's their own fault, of course, so nobody (except themselves maybe) minds.
Hello everyone. My computer keeps restarting by itself. It has done this twice. The first time it broke on Thursday and came back on Sunday. The same thing happened the second time, but it's Sunday and it still is not fixed. I'm so sad now because I have a lot of data on that pc and I don't want to lose it. I do not have the Recovery Console installed, I do not have any XP cds and that F8 crap doesn't work either. I have tried plugging and unplugging but it still won't boot. Both times it was caused by a power failure, the power was turned off while the pc was still on
