I have been futzing around for about two weeks, and getting nowhere, so I am swallowing pride, and contacting the pros...
I have a Dell Inspiron Laptop, model 1545, running Win 7 Home Premium 64 bit, that has a couple of serious issues:
1. It cannot connect to the internet, either wirelessly, or with an ethernet cable. (Wireless router is up and running)
2. Most programs will not run, returning the warning "The subsystem needed to support the image type is not present."
When I first got this laptop from a friend to clean, I was able to run Avast, and remove about 500 infections...since then, nothing wants to run, and I lost the internet. Trying to enter "Device Manager" to uninstall, reinstall, but I cannot even get into "Device Manager".
Any ideas? or am I looking at my future boat anchor?
