please help!
i just joined this forum today and i've been browsing for a while, trying to get help and see if i can solve this by myself, but i have no idea what most of you are talking about.

i keep randomly getting a blue screen that says:

DRIVER_IRQL_NOT_LESS_OR_EQUAL

it will show up in the middle of me using the computer, sometimes when i'm downloading something or other times when i'm playing a game (i've tried to play the sims 2 three times and i get this message each time about two minutes into running the game). then my computer restarts and my computer tells me it has just recovered from a serious error. the error code is:

BCCode : 100000d1 BCP1 : E2a430b4 BCP2: 000000FF BCP3 : 00000000 BCP4 : FF84F1BF OSVer : 5_1_2600 SP : 2_0 Product_1

then it says the files that were included in the error log are:

C:\DOCUME~1\Owner\LOCALS~1\Temp\\WERb09f.dir00\Mini041306-03.dmp
C:\DOCUME~1\Owner\LOCALS~1\Temp\\WERb09f.dir00\systdata.xml

i have windows xp, i don't know what else i need to tell you about the computer, i don't really know what kind of processor or anything. but if anyone knows why i'm getting this message or how i might fix it, i'd really really appreciate it.
