Windows 7 64bit: While I am attempting to install a driver on cd rom, the disc suddenly crashed inside the rom and it also crashed the cd rom, then the OS remains the same so I tried shutting down the PC, but while shutting Down, BSOD suddenly flashed on my screen, I disregarded it, since I think it's because of the CD ROM, but when I removed the CD ROM from the MoBo, while booting, it says, (oh i forgot,) but it says something about BOOT Image corrupted i guess? i tried everything but I ended up re installing the OS, but i have to save very important files since it was saved on Desktop i forgot to back it up, so what i did is I re installed by NOT formatting the drive, it went well, BUT my PC became Extremeeeeely slow, it's like im working on pentium 1, because i was just trying to delete a single 200mb file and its duration is morethan 1hour, Yes! It's too much for AMD Phenom quad core, 3.2ghz, and 4gb ram. so i just copied the important files and tried formating again i deleted the primary hard drive which the OS will be installed, and til now on 3days reinstalling, its my 11th time on formatting, I can't get through on desktop without getting any error e.g Winmail.exe, ie4iunit.exe rundll32, etc. which it says it cannot be initialized or something, so i tried downloading the .exe and dll files, and i had to change a lot of permission settings to do that, anyway i think my problem there has been fixed because i tried restarting it and I didn't get the errors and it's speed is normal BUT when I tried to run apps, or installers, it says APPLICATION ERROR UNABLE TO START CORRECTLY, as in every apps i tried to run the error's just the same, BTW i am using bootable flash disk since my CD ROM was broke. I can't see any answers on web so please help me? what possibly could be the problem and what causes it to be like this? i am looking forward for your answers TIA!
