Windows Icon problems and TweakUI won't install

Well, ever since I got this pc finished it's been hassle after hassle. I really can't hit a lucky patch.

I posted before on what I have for a system, and I'll post it again for the ease of things. What my question is, is what is going wrong when my shortcut arrows on my icons are white fuzzy squares, and icons for certain programs, links, and exe's are fuzzy white squares? I think it's a system32.dll error, but am not sure.

I also can't install Microsoft's TweakUI, due to a "GetDllDirectoryW could not be located in kernel32.dll" My only hope is that I don't have to reformat again, because I've tried that and it doesn't solve the problem for very long.

If you need a screenshot of both errors in action, I can post one in deviantart. Just tell me what you guys need. I've found bit-tech to be more than helpful in these situations, and I'd like to thank everyone here for their kindness.

 

Here's the system specs.

AMD 3400+
MSI MicroATX mobo
OCZ low latency PC4000 2x512
Sapphire Radeon X800 Pro TOXIC
2x Western Digital SATA 200gig hdd's
Soundblaster Audigy 2
Swiftech Liquid cooling blocks

 

Try deleting ShellIconCache file and rebooting, a new copy will get built.

XQ Setup has options to delete the file & also to increase the cache size (Under Interface/Icons)

Arrows and some system icons are in Shell32.dll IIRC.

 

Awesome, I'll try that quick.

 

Ok, well, I bumped the cache from 500 to 2000 and it still didn't change them back. I think my system32.dll file is screwed up, but yet, I can't change it back to stock, due to the fact that I can't install tweakui. What the douce?
