You have got to be kidding. CCleaner does NOT touch your HARDWARE in any way except for the hard drive which it cleans files from that and unneeded. It simply removes files from the hard drive by CLEANING out what is JUNK.
Your modem kicked off. Oh my god, please tell me you've heard of.. *gasp!* ISP's going DOWN for some time or even dropping connections!
Dropped connections happen all the time. It's a COMMON occurance, especially if you use a free ISP such as Juno or NetZero for their free service. After 10 hours they cut you off and you can't get back on, as you'll get a weird error message.
Trying to tie those things in to software that works fine can cause paranoia. Is that what you want to do? It was a freak coincidence. Next time stop and think logically before you get yourself in a panic.
I admit, I had a good laugh over this. So did my PC Hardware & Troubleshooting professor, along with the rest of the class. Anyone else find it amusing?
