I just reformatted a Dell Inspiron 530S Desktop with Windows 7 Home Premium 64-bit. It's coming from Vista 64, but this is not an upgrade but rather a full reformat/reinstall.
Once installed, I noticed that IE was crashing immediately every time I opened it.
Next, I tried to double click the C: drive in Explorer and explorer.exe crashed.
I then tried to load a CD with some drivers
on it, and when I right clicked on the CD drive under My Computer in order to click Explore - exporer.exe crashed again.
In device manager the only hardware with a yellow caution sign icon is under Display Adapters and is the "Intel G33/G31 Express Chipset Family" but I doubt that would cause all of this.
I'm at a loss of what to do -- why would the OS be having so many issues on a new, fresh, legitimate install?
EDIT: In addition, when I try to install software it tells me that the "The Windows Installer Service Could Not Be Accessed"
