Suddenly my system has become very slow/freezes when using either Photoshop Editor or Canon DPP. I can work with the first picture without a problem but when I try to work with a second my system locks up for about a minute then unlocks. This happens in both Photoshop and Canon editing. I have tried defragmenting, registry cleaner, virus scans, etc. and no problems were noted. Everything else seems to be working fine and this problem just started out of nowhere. Any help would be greatly appreciated.
