I recenlty upgraded from 32 bit vista to 64 bit and I noticed that my PC is a bit slower. along with that programs like TAT and driver cleaner 1.5 will not work correctly. TAT boots then shuts down but is stil running in processes. I THINK the problem maybe that I delted the second partion in the HD when isntalling vista. Im not sure how big it is or if all hardrives secondarys are the same but how can I fix this?
