System Problem

I had a lil water spill on my PC a while ago water got to my video card/PCI-E slot I got distorted image for a bit, then after I dryed the components everything was normal, then I got my 74gb raptor everything was good till yesterday when I got a valve update for CSS, the game started to act up, so I rebooted my PC when I got this "error loading operating sys", I logged in safe mode backed up what I needed and try to do a fresh install of my OS on the raptor, when while installing windows it asked to find cmprop.dll/cmprop/dl_ and iexplore.exe/iexplore.ex_ ... I dont really know what is the problem, should I get a new board? should I get a new OS CD?

my sys:

DFI Lanparty Ultra-D bios 3/10
BFG 6600 GT OC
Benq DW1620
74gb raptor
winnie 3000
fortron bluestorm 500W

Were you overclocked? I'd recommend downclocking to stock before you install XP.

Always try installs more than once if you encounter problems.
