When my system won't respond and I hit Ctrl+Alt+Delete I get the message that ("Rnaapps" is not responding), I click close and I am able to continue. This has happened at different periods of useing my computer. When I have 1 or 5 programs running, or when none are when I am going thru the WIN95 shut down process and the screen will change to the WIN95 LOGO and will stay there.(which normaly is about 1 to 5 seconds depending on how much time and info i had preformed earlier, then goew to "it is now safe to shut down your computer", screen) This has happened often. what can cause this and how do I fix it? is there a program the I can get that will "seek and repair", problems like this?
