hi, i just reformated my pc couple days ago. and i installed some softwares using old installers. but after i install some softwares n restart the pc my pc freeze again and have to use task manager to terminate explorer.exe and run it again. so i deleted all those old installers and downloaded new ones and seem to be okay. but last night i left my pc on to download movies and when i switchd on the monitor this morning i cudnt open my total video player(tvp) and adobe audition 1.5(aa1.5), again. when i open my tvp the error report appeard; AppName: tvp.exe AppVer: 126.96.36.1998 ModName: tvpskin.dll ModVer: 188.8.131.523 Offset: 0000df94 and when i open my aa1.5, it dissapears after loading.if i open control panel and choose "add or remove programs" i cant delete tvp and this error appears. "C:\Program Files\Total Video Converter\unins000.msg" is missing. i can only reinstall it after deleting it manually from program files.same thing happens if i want to delete Antares program which is a plug-in for aa1.5. how can i fix this.? is there any way to scan or detect any missing or corrupted files.? and theres another problem. before i reformat my C drive, i installed windows to D. so after i formated my C, then I reformated D as well. so its all clean but in boot screen theres still 2 windows XP options (C and D) and i open msconfig and BOOT.INI and clear the unused option which is D. if i turn of my computer, my pc doesnt freeze but instead an error window appears. it says something about asking me to select normal start up. i didnt change that except for BOOT.INI and if i change to normal start up, both windows XP option will reappear again if i restart my computer. and i didnt choose normal start up but selective start up instead, it will then freeze again after restarting. **i still keep some other installers from my back up disk, but for tvp, aa1.5, antares, firefox, they are all new. **last time when i open my windows live messenger, the same thing like aa1.5 happend, but it dissapeard after sign in.but i havent install it in my new computer so i don't what will happen next. thank you.
