Ugh get a crash in the game alot

Probably someone already asked this but i needed help badly and whenever i equip some items to my character it exits and crash into some blue screen etc idk and this been going on for a long time and i dont know what to do and im not that kinda smart on computers and such

well, without knowing anything about your computer... all I can recommend is to try running a chkdsk (if winXP or 2000) or scandisk, then run a disk defrag. Scan for viruses with updated virus scanner. Can you list the error code on the blue screen, what operating system, etc.?
