Three days ago I had a virus on my home PC. I used the usual virus software - SpyBot, Avast and Remove-it Pro. It appeared to go, but then my hard disk started making a repeated four short scratch sound and the whole thing slowed down. It then stopped.
A quick search on the net suggested it was a duff hard drive. I had a few items I hadn't back up and wanted to retrieve them, I also had two other smaller drives in that PC that I wanted to access. So I added the drives into another PC to see if the one that had stopped could be accessed and to retrieve data from the other two. I moved a few wires around on the mother board, attached the drives and turned on my newer PC.
The bad drive made the same scratching sound, then I got the blue screen of death. I haven't had that since Windows 98 many years ago. I took the drive out and reconnected the new PC's original. When I rebooted the same blue screen appeared. I switched off, rebooted in safe mode and did a defragment on the harddrive. Then I went into the bios to swap boot disk around - at this point I didn't really know what I was doing.
Then I restarted and got nothing.
Back in bios, adjusted again and rebooted. I got Windows back but as it loaded the system repeatidly rebooted. Switched off more bios dabbling.
Now I had bits of PCs all over the place and a dead old PC and a dead new PC. I swapped some wires around rebooted. Nothing.
Tried to reboot from Windows CD. Nothing.
Took the cd drive out of my old PC coupled it up to the newer PC and rebooted with Windows CD in that. Nothing. Back to bios changed boot up drive to new installed CD drive booted up. Success!
I decided, as the system was fairly new, to reformat my drive and reinstall Windows. So I could start from scratch and remove any damage I'd possibly done.
I did all that and then realised I no longer had all my old emails. Luckily a back-up from March allowed me to get a fairly good majority back into thunderbird.
But then found after setting correct IPs etc that I couldn't access the internet. A look at the system showed there was no network card driver. Whoops I'd forgot to install the motherboard drivers. An hour or so later I had internet, but no sound, or option to get my displays into dual mode. I'd no idea what make the sound card was to download a driver. It didn't appear to register in Windows. The list of problems continued.
As I write this I've managed to get most back together. I still only have one monitor, but basically for the last few days I've been fannying around trying to get back to where I was Friday morning. . It made me think - if I get a headache I see a doctor. And if it was really serious I wouldn't grab a scalpel and go fiddling about, so why do I think I can do it to the brain of my PC?
I'm not a brain surgeon.
