I got junk in my computer

[Raven]

hit start > find files> (search for) files named *.exe the "asterisk" being your wild card....ok [meaning every executable[.exe] file will pop up ) any files you see.....that you suspect are the culprit.....
and tons of-em that come up you want to keep... you can highlight one so that that it's merely selected and then right click it to reveal the properties as in....
when it originated ...... or was last accessed.....look for dates... specifically
then decide when your PC was running excellent and delete any files that were (VERY IMPORTANT WORD) "CREATED" on or after that date.

thats one method......
----------------------------------------------------------------------------
check your start menu and see whats starting and running when you boot up...as too many things running at once will slow things down to a snails pace...ok also go into> my computer>control panel>add/remove programs and check whats in there now.

the secret is in the >>>>>DATES<<<<< you can search your PC for files (any files) created on a particular date} say 3-25-05 every thing went slow..... so anything created on that date you can usually DELETE! always delete things very cautiously and slowly...is the rule.
until you get back to happy town.
