Try booting it up in safe mode. Worth a google but here's a random link with advice: http://www.computerhope.com/issues/chsafe.htm#02 Safe mode bypasses the programs set to start on startup so often lets you in to fix what's gone wrong.
You might try loading the last good configuration. Sometimes that works. Once you are in it's worth trying to find out what's caused the problem - full virus scan is a good start.
that sounds like one of the sasser worms, exploits a hole in windows xp and 2000 SP2 plugs the hole, but once you've got it its hard to shift. I couldn't from my other PC running 2000, despite downloading various kill programs, so ended up doing a reformat..
The trouble with safe mode is the buggers are clever now the old blaster worm could be shifted but now they write it to multiply into parts of the system that are not scan-able during safe mode, if your lucky and you haven't started to often it hasn't run riot, especially in the registry....
Do a search for sasser worm, and see if the symptoms are similar
Which version of xp are you running pro?etc do you have a bootable xp disc or manufactures restore disc?......can sometimes re-write the MBR (MASTER BOOT RECORD) or use the recovery console in bootable xp disc
The usual problem is with XP doing an update behind your back and on rebooting it hangs. It usually offers a choice on booting up but defaults to 'repair windows'. DON'T CHOOSE THIS OPTION! Pick the 'Boot windows as normal'.
Might take a few reboots but at least saves a complete rebuild.
TBH it's unlikely to be be a virus, more likely corrupt operating system.
I'm an old fashioned hardware engineer (ie pre PC's, when proper computers were 3 phase and weighed several tons). Everyone blames virus' these days and I don't see that many really, 9 times out of 10 it's updates or some new application.
well what im planning on doing (when i have the money) is buy another hard drive, boot into linux from a cd, mount both the new harddrive and the origional(infected) one and copy all my files accross, then wipe the origional and install
Sounds like a plan mate, but couldn't copying using linux (or any system) copy the virus as well on an all file copy? (can't comment really, out of my depth on this now )
i wouldnt have thought so mate, but more than willing to be proved wrong, have installed linux a few times before and tried to get to grips with it and failed, necessity is going to make me learn tho as i have hundreds of gigabytes of music movies documents and pictures on that pc that i just can't afford to lose, serves me right for not making backups
my understanding is, if the virus was present in the folders i was moving, i would see the file? as the virus would not be able to hide in linux?
Don't know for sure mate.
Would've thought thought that any virus would be lurking around the op sys files so if you can access them 'remotely' so to speak you'd be hunky dorey. Google 'BartPE', you'll eventually find a site that enables you to make a bootable cd. One of the options is to include virus checking. Been some time since I used it but it enables you to access all the files on the disk and copy them at will.
I've been caught out many times with things like this so I tend to take a belt and braces approach these days (though I must add it's never been needed so far but us Jerseymen are renowned for being cautious! )
thanks very much for your advice paul, will have a search about during the week for Bartpe, the weekends arent exactly my best time for doing technology related stuff hopefully i can get it sorted, thanks mate
Just as a side note if your scans can't find anything, ive had this from bad memory. Ive got one server that if you use both memory slots on the motherboard it falls over sooner or later, and gets all weird and corrupted on boot. Sometimes it used come up and fall over after a random period of time, other times it just hung with a blank screen right after POST. I did have a spate of reseating all the cards/memory in it which seemed to settle it down for a bit but it always came back.
I gave up and took half the ram out of it (now its got a whopping 256Mb, but its managing being a mail/web/mythtv/fileserver just fine) and its been good as gold since (last reboot 6 months ago when we moved ).
Definately not a virus, its running linux as are all my computers...
If you copy across a file when booted from linux and its infected and you copy the file to a windows machine, when you re-run the file on the new windows install it will simply get reinfected as sometimes viruses change executeables and tag themselves onto the end of a legitimate program. You need to copy them all across, and virus scan them on the clean install before executing/viewing any of the stuff from your old machine.
