But could you give me some more info on downloading/installing (or what so ever) of the SP3? You mean i should just download the whole SP3 update again, or i should download an illegal copy of WinXP pro SP3?
Its perfectly legal, its just a standalone SP3 installer like I said. Here is the link:

I recently had SP3 give some errors off of a regular Windows Update install, so I got the network install and it again installed, so yours should be able to as well. Turns out the error I got wasn't able to be fixed by a reinstall of SP3, but that taught me that you can 'reinstall' SP3, and I think without your Windows disk that is the best way I can think of to replace corrupt system files.
and if I reÏnstalled SP3, what should i do with the newly created restore point?
Hopefully nothing. The idea would be that corrupt system files/drivers get overwritten. Its kind of a long shot, but until you can get some answers about your event viewer I can't do anything other than suggest what I did.
I'll try the system scan, but isn't ESET just something like Housecall? (I'll run it anyway)
Yes, so. I said I
suggested eset's scanner. I didn't think I was going to have to explain why I suggested it, but since you don't appear to be happy without every detail spelled out I'll tell you. Housecall seemed to work fine for me several years ago, but probably 10 out of the last 10 times I've tried to use it on various systems, whether it be my personal XP or Vista machines, or a couple different XP machines at work, or a 'client's PC, or my dad's laptop I have never had much luck getting it to work. As in it didn't work at all, no scan, nothing, this is with trying both the ActiveX and the java ones with IE6, IE7, FF2, and FF3. ESET's ran perfectly fine on the only 2 computers I've tried it on, and I've seen it pick up things that AVG Free 8 did not.
You've kind of gotten yourself into a mess here without having a real copy of XP, because you can fix corrupted system files with that. But I guess even with one you'd need to make a slipstreamed one with SP3. When problems suddenly come up, its more common that you've got something nasty software wise rather than hardware. But what you should be doing initially is running things like Memtest on your RAM, ESET's online scanner for viruses, updating video, sound, motherboard chipsets, ect drivers. Also effectively noting what causes the errors and if its reproducable in the type of error it causes, noting what the error is, checking event viewer, and other things.
So I would make sure you do all of that first, before trying my reinstall SP3 from a network/standalone installer suggestion.
