Try uninstalling all .NET versions. It's not needed for most systems and there's an issue I bumped into a few months back. If you want to read about it, research -> NGEN FORCE ASSEMBLIES COMPILE
So my computer was running just fine about a month ago, but recently it's gotten slow, and getting worse every day. The CPU % is rarely under 50. I scanned using MSE and MBAM, both of which came back with nothing. I've been uninstalling old programs, but it hasn't seemed to help too much. I also dusted it out.
My computer is an Acer Aspire (not sure of the exact model) running windows 7 ult. 32-bit. Processor is an AMD Athlon 64 x2 5200+. 3 gb of ram.
Any help would be greatly appreciated!!
