My system crashes when trying to install a new program. It has done this on quite a few. I open the aotomatic install program, it identifies the disk or CD I want to install, begins the installation, then simply hangs. Can't get out of it with control-alternate-delete. I had a similar problem installing Win95 and had to turn the internal and external cache off. I have tried this now, but everything runs really slow. Any other options besides a new CPU, or could another setting be wrong? We didn't have any trouble using this CPU with Win 3.1. I have a Cyrix 133 mhz, Opti Viper motherboard, 8 megs of memory, Champ 2.0 hard drive, Alsop sound card, 3.5 drive, modem. Everything seems to be in working order except for these lockups.
