This is regarding my parents' home computer, and not my own, so I apologize if the info is somewhat sparse. This is also the first time I have used these forums, so I am also sorry if my post is unhelpful or vague.
It is a refurbished IBM Thinkbox, and it is running Windows XP Home (SP3).
The problem is as follows. Recently, I became aware that it had some how been infected with malware, and I was working to fix the problem for them. I was in the final stages of verifying that the problem had been removed (which I later found out it hadn't, but that is no longer the issue) when the computer suddenly froze. I was unable to do anything, so I turned of the power.
When I turned it back on, however, the USB ports were no longer giving any power. Well, the mouse did for several seconds until the OS began to load, but otherwise there was no indication of power from any of the six ports. The PS2 ports still work, and the BIOS still shows that the ports are enabled. The virus is gone(to my knowledge).
The tower has had other mechanical failures before this, such as a fan failure which we replaced after it had caused the RAM (I believe) to basically cook. While attempting to find the source of the problem, I discovered that the work around my brother had devised was no longer where it was supposed to be.
I guess my overall question is this: Is this more likely to be a hardware, software, or user failure that caused this, and what are the suggestions to fix it?
