I popped in my Elder scrolls IV oblivion cd and install sheild froze.Then after a few seconds popped up and said Error 5009. I tried another software cd I had and its the same thing. I can't even install anything I download off the internet without it freezing up on me. This seems sudden to me considering I have had no problems until this. Compaq Presario CQ61 Windows 7 64 bit AMD Athlon II Duel-Core M300 2.00 Ghz 3.00 gigs of ram AMD 880G ATI Radeon HD 4200 I run adaware and AVG free I turned them off and still the same problem. I thought about uninstalling them, but I wont be able to reinstall them untill I get this fixed. Suggestions please.
