So another girl asked me to repair her computer - the symptoms were slow laggy startups and overall performace degradation. So I'm like "ok" and go up to her room thinking it would be a quick 5-minute fix.
I get onto her computer and check the active processes. csrss.exe is taking up 50% of the CPU cycles... red flag omg? So I disable her other virus scanners, download Lavasoft AdAware and run a scan.
102 Critical Items.
Okay, not too bad. So I check all of them and clean the system, then reboot windows.
Upon rebooting, I get a BSOD even I've not seen before -
"INVALID OR CORRUPTED REGISTRY FILE."
At this point I'm pretty much "oh shit oh shit" but she said that she's gotten this error a couple of other times before, and rebooting fixed it. This wasn't much consolation because... wtf corrupted registry?! So I restart it anyway.
Now get this - it goes directly to the "select windows startup mode" screen, and when you attempt to select any of the options it prints the message -
"MISSING WINDOWS COMPONENT
C:\WINDOWS\SYSTEM32RUN WINDOWS REPAIR WITH 'R'"
Okay, what the fuck happened to the Windows install?! At this point I'm starting to panic, because wtfbbq. I ask her for the windows installation CD (because at this point, the OS is toast), and pop that in there.
I take the message's advice and press 'r' to run the repair utility.
"PLEASE INSERT WINDOWS BOOT DISC"
...LE WHA? She has neither a boot floppy nor a floppy drive to put it in. So I'm like "shit". I reinstall windows and manage to preserve the existing filesystem, but it was really messy.
So now its working, but there are a lot of missing drivers, most notable the network ones.
And they're neither on the drive nor the CDs. And I clearly can't connect to the internet since I need them to connect to the internet (OMG CIRCULAR DEPENDANCY) and omg. THE IRONY IT BURNS US ASUUUGHHH.
So yeah, now I feel like shit because I completely managed to trash her system somehow. Mushu--;
