Unless you know the name of the file or the date you added it, one by one is the only way to guarantee you find it and nothing else. You can use any of several programs such as Clean Pack Installer or Content manager to identify hacks and mods but, it may not be a hack or mod causing the problem.

Slowness is probably a specs issue. You need more RAM, a better graphics card and maybe need to update your drivers and free up some hard drive space as well. The other option to speed it up and cure the crashing all at once is simply remove your downloads folder and learn to play without CC.

use the [ and ] keys to move them up or down.

Your sim does have the needed reagents in her inventory, or you have the no reagents hack? Some spells cast on your sim, some another sim, som an object and some on the ground.

And is it 10x speed at least? an older drive may not be and if not, it won't read the disk - as I found out. My OEM won't even though it is a DVD read only drive but, my newer LightScribe Drive is fine with it.(HP brand fyi)

Don't uninstall yet. In My Documents/EA Games/The Sims 2. Delete the Accessories.cache, Groups.cache and cigen(if you have it) files and try again. If that doesn't work, move the entire Sims 2 folder to a safe location out of My Documents and try - the game will re created the files it needs.

ONLY if all of that fails will you need to uninstall. Any saved games will be in the Sims 2 folder you moved if you want to try to put them back.

That is the default colors, plus yellow as well. No roof angle change. To use them you need to build a third floor one square smaller than the secons and first roof with floor tiles under auto roofs, then you can place the decorative piecs, rotaing them to fit as you would any other object in buy mode. Note that floor behind the fancy roof is useable but, it cannot have any exterior doors or windows due to the use of the decorative roof pieces surrounding it. Makes a great vampire loft in apartments though.

Is it on a foundation? If so that's the problem, you can't do yards and foundations both in one unit. Is there an elevator, stairs to the roof that do not go into a room, a missing piece of balcony fence, the bookcase door on an exterior wall, a closet on an exterior wall? Door facing the right way (mat outside)?

If it's on a foundation and you want to keep the yard; while it's residential use the cheat boolpropconstrainfloorelevation false and change the yard fence to a half wall. You nee the cheat so you can make the half wall connect to the foundation. Turn the cheat off (set to true) then rezone.

Use all of the subfolders you want i.e
My Documents
 EA Games
  -The Sims 2
  -- Downloads
   ---  Walls
    --- Floors
    --- Female Hair
    --- Living Room
    --- Challenge Sets
.........
You get the idea

It may also be that you have anti aliasing forced. If nothing else works try this.
FORCED ANTI-ALIASING: The Sims 2 will have graphical problems if anti-aliasing is forced to always be on. To fix this:
   * From the Start Menu, choose "Control Panel"
   * In the Control Panel, choose "NVIDIA Control Panel"
   * Select "3D settings"
   * Under "Appearance", select "Adjust Image Settings with preview"
   * Choose "Let the 3D Application decide" option and Accept

If that isn't it, then it is possible hyperthreading is enabled in your BIOS and you need to disable it. If ou are not comfortable changing your BIOS settings, contact a techinal support rep at NVIDIA and they can help you do it properly.

If the drive cannot play a movie, it cannot install AL. DVD is not the same as CD Rom. My neice gave me fits insisting she had it in the DVD drive, no it was a CDRW drive not a DVD drive, double check yourself and your drive.

Very similar to my system: 2 gig RAM, GeFoce 5500, 3.0 ghz processor under XP home.

First make sure your screen save is set to wait 60 mins or longer, next make sure you are in always on power mode (both from control panel > display).
Finally make sure some other task, program or process is not causing those pop up baloons  and that your virtual memory is set high enough  so you don't get the increasing page file message.

There is a tutorial at the EA Sims 2 site.

Known Glitch, ans are disapearing cell phones, losing cooking skills when you move and a few others. Over at MoreAwsomeThanYou, there is a fix for all of that. I'd recomend it.

CleanPack from Mod the sims 2 and Content Manager from the EA Sims 2 site. Clean Pack gets most of them but, there are a few of those all numbers type that it doesn't get a description for while Content Manager does (and with the CM if it says error 90, just click OK; just means it doesn't like your internet connection and can't give you the creator of the file is all.)

I assume you mean in Belladonna Cove; try it in another neighborhood. Belladonna hates beach lots most of the time.
