I'm trying to help fix my stepfather's computer which is running Windows Media Center on a Dell XPS laptop (2006 model). There are whole a lot of strange things going on. Earlier it was getting a BSOD quite frequently because of a problem with Win32k.SYS. This would occur when Windows starts loading, but other times it would happen later after trying to run certain programs. This problem seems to have been resolved for some reason, but other issues remain. The computer is running very slow although according to the task manager nothing is stealing away processing power. The other big issue is that the computer keeps bringing up a searchindexer.exe error message just about anytime we try to run a program. I have no idea what's going on here or how to fix this.
