Computer restarts unwantingly

[snoopyflipz]

Hi my computer keeps restarting when downloading and playing World of Warcraft. It is saying that there is a problem with drive C Fat32. I am not sure what this means or how to fix it. At first I thought there wasn't enough Ram on my computer. (My computer had 256mb of ram and the requirements were 512mb) So I uninstalled it and went out to buy more Ram. I now have over 1G of Ram and it is still restarting telling me it needs to check the disk for consistency.
What I am Running: ACER Aspire T135, 2.01 GHz, 1.18 GB of Ram, AMD Sempron Processor 3300+, with XP home Edition.

I would just like to know what I can do to stop this from happening and why it happens

Do you have the exact error message given? Are you presented with a blue screen of death? Is there anything in the following directory: C:\Windows\Minidump?

It is saying that there is a problem with drive C Fat32

That is referencing your HDD (and/or your file structure) as the issue. Open My Computer > Right Click the C: Drive > Properties. Next to "File System" does it say NTFS or FAT32? Your PC shipped with XP and I'd be willing to bet it shipped with NTFS as the file structure.

If it says FAT32, and you're using XP, have you reformatted and reinstalled in the past? You might want to try converting the file structure to NTFS.

Next to file system on drive C it says FAT32. I don't think that I have reformatted or re installed it on this PC.
