Windows 7 or Vista won’t start, Computer shows black screen during startup
The black screen you’ve seen is commonly known as the Black Screen Of Death. The name is cool but it sucks. Nobody want to see a black screen on their monitor screen.
After starting your Windows 7, Vista, XP, NT, W2K, W2K3 or W2K8 PC or server the system appears to be normal. However, after logging on there is no desktop, task bar, system tray or side bar. Instead you are left with a totally black screen and a single My Computer Explorer window. Even this window might be minimized making it hard to see.

I must remind you that this tool will not fix all black screen issues. There can be many causes. But if your black screen woes began in the last 2 weeks after a Windows update or after running any security program (including Prevx) to remove malware during this time then this fix will have a high probability of working.
3 simple tips to avoid black screen of death
1. Keep everything up to date. Most malware exploits known vulnerabilities for which patches already exist. The best defenses against malware of all kinds is to ensure that your operating system (e.g. Microsoft Windows) and applications (e.g. anti-virus programs) you use are all updated with latest patches.
2. Protect Against Malware. If its true that the black screen of death is caused by some variant of the Daonol family of Trojans, then it makes sense that anti-malware software could protect your PC from it. The following articles can guide you through the steps to protect your computer against malware:
3. Run the Fix. While Prevx was mistaken about the Microsoft updates being guilty for causing the black screen of death, it still has a pretty solid reputation as a security vendor and its research into the root cause that triggers the issue seems to be accurate. Prevx has stated that its fix does not work in all cases, but running the fix has a fair chance of fixing the issues within Windows that have been determined to trigger the black screen of death. Download the Prevx fix and give it a shot.
