What you might be able to do yourself:
1. Get the hard disk out.
2. Connect it to another PC using a USB2 to IDE/SATA-cable
3. Run chkdsk on that disk on that other PC and see if it can be repaired.
4. If not, while still on that other PC, delete the partition and create a new one.
If successful so far, put it back in your PC and reinstall Windows XP via the 'back to factory conditions' method as described by Acer.
When I try to start my notebook I get the blue screen "Checking file system on C:(File system is FAT32) It goes through the process (Volume serial number is EEAE-8C9A in case that means something to anyone!) until it's 100% checked, the message then is windows found problems which it could not fix, soory it flashes up on the screen only for a second and I can't replicate here all of what it says. I then get the blue screen of death for a nano second and don't get enough time to see what it saysbut the last message is Error in writing the output log. It then tries to start but goes back to the checking file system process again and so on. I can't start it safe mode or safe mode with prompt.
Running Windows XP, just got an additional 1G of Ram added (now 2G) but it did work after that, so I don't know that's the problem.
I'm not technically minded so I guess I'll need to take it to a shop but if anyone has experienced this and knows what the problem is or how to solve it that would be great.
