Well, here is my problem.
I was installing a custom windows theme, and I accidentally deleted a system32 .dll ( browseui.dll is the one )
The outcome was explorer.exe crashing on startup every time, I have the windows vista disk but I can't configure my bios to autorun it :/
Though, this computer is very new and I don't have much on it that I would mind losing, so if anyone knows a way to wipe my hard drive clean I am up for that option too.
Help :c
