I am running Windows XP on a Compaq Presario 2100 laptop, which is about 2 years old. This is a problem I have had for some time (about 4-5 months); I first started having the problem after my computer was running very hot for a while (a fan broke). This problem started to appear soon after. What happens is, I will get struck by a Blue Screen of Death (I believe the error has to do with Kernel/Page, sorry I know this is important but usually it restarts and I am not around), which nearly always automatically restarts into an error which prevents Windows from loading...the error is "Windows\System32\Config\System Corrupt or Missing" (recently one time it was a ntfs.sys file missing). I usually fix it either by the recovery or, more often, format method. At first it would take a couple of BSODS to bring that error, but now it happens after one BSOD and restart. After I format the install will last from anywhere between a week or two, or a day or two, before the BSOD strikes, restarts, and the aforementioned error appears (and I then format again). I know I should have taken care of this long ago, but got busy with school, etc. So, I am thinking it might be hardware related? Thanks in advance for any help or advice.
