Thanks Ivan for the advice, but I was already aware of that.
The computer is running fine (mostly) but, like many high-end computer in average hands, it was poorly taken care of. One example; it had four antivirus installed... but not kept updated. It was a bit like sending four retriever to get one duck.
It is also packed with (I will keep within decency) crud, which is partly explained by my brother lack of knowledge about "uninstall" W7 features, coupled to a very large HD capacity, and a teen who, well, act like many teen.
But my biggest problem is internet connection. With the battery dead, I can't get to a "free Wi-Fi" location (like the nearby park), and I can't plug an external dial-up modem. I did found a dial-up that could be plugged in a USB port, but delivery date is mid-March at the latest.
Tonight, I tried to dust the PC and, using a few "tricks" found on Youtube, restart the bugger; no such luck.
But enough with the long-winded lamentation.
