Hi all, Sorry to have my first post be a plea for help but alas here we are. So apologies in advance for being "that guy" but I'm really dumbfounded by this one. Hopefully someone here can point me in the right direction. Two nights ago my Windows XP Home Edition computer was infected with one of those trojans that disguises itself as a fake anti-virus software. It was called WindowScan I think. As soon as it started to scan my computer I hard booted the machine before it could finish. Now I can't get back into regular mode nor safe mode. In both cases the machine loads to the Windows title screen then I get a blue screen of death that reads... --------------------------------- A problem has been detected and windows has been shut down to prevent damage to your computer. If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps: check for viruses on your computer. remove any newly installed hard drives or hard drive controllers. check your hard drive to make sure it is properly configured and terminated. run CHKDSK /F to check for hard drive corruption, and then restart your computer. Technical information: *** STOP: 0x0000007B (0xBA4C7524, 0xC0000034, 0x00000000, 0x00000000) --------------------------------- I've seen other threads here and other places that describe this error and the problems were traced to three things: the registry is bad, the drivers are bad or the HDD is bad. What's making this difficult for me is that I used Windows Repair to set the drivers to default. This didn't change anything. Then I created a UBCD4Win boot disc and through it restored the registry to a copy of itself from a few days ago. This didn't change anything. Lastly, using the UBCD4Win desktop I am able to completely access to boot HDD so that makes me think it's okay. I've run spybot via UBCD4Win and although it did find some bugs it didn't find anything that was causing this BSOD. What else should I try? Also please let me know if this problem has already been addressed elsewhere. I apologize if this is a duplicate thread and thanks for taking the time to read this post.
