(last thing that was happening with the computer before the problem) was runing a bot to play online game, stopped and closed any program open and turned the pc off. (regular routine thing right?) turned pc on at later time same night, got and error msg The application failed to initialize properly (0x0000005). Click on ok to terminate the application. when the pc starts up (upon actually having windows fully loaded) also i should not that there are 2 of the same error msgs. from here the pc seems to be fine. In fact I might not have noticed anything wrong so quickly if it was not that my windows looked different, I always keep it on "classic start menu" style but it looked like "start menu" so I click from start menu Ad-adware program and i get the same error and the program will not start, then I google the problem and found this site. now here is the extreme problem ( i think at least) i read to d/l HijackThis and follow the directions on not posting or doing anything like a noob. so i try and d/l, fine it d/l, I click to open the application to actually start installing the HighJackThis and i get the same error as before ( 2 times again) and again like with Ad-adware it does not open. certain programs will not open, mostly any or them regarding them being anit spyware, virus, trojan etc. other error is safe mode will not finish booting (?) at screen I select start in safe mode, it does its thing, then i get a black screen saying safe mode on the top, with nothing else, no icons, no start menu, nothing, not even mouse functions. trying to open the bot says this Run-time error '339' Component 'comctl32.ocx' or one of its dependencies not correctly registered: a file is missing or in valid. microsoft windows XP professional amd sempron processor 2600+ 1.61 GhZ 2.00 gigs of ram physical address extension i don't know what other info i can give, it would be nice to receive some help. thank you all for your time in advanced and pardon for the long read. also i forgo to mention I can NOT open system restore, I get the same error as before. one more thing that will not open but will not give me error is device manager just found out another thing, I can NOT open ipconfig from start, no error though. another thing I forgot to add was aside from the ...0x0000005... error, i get a second error when i boot up it says: error loading C:\WINDOWS\system32\NvCpl.dll Invalid access to memory location.
