First of all, I'm not sure if this is the right place to post this, but it has an issue related to windows.
I woke up, pressed my desktop power button like every day else. It booted fine and stops at syskey password box as usual. I typed my password in...WTF? My password is not correct! Yes, I'm extremely sure that I remember my password! Because I do this everyday! And then when I tried the 3rd time, the desktop reset by itself. After that, I can't boot it up anymore. It has power, fans spin beautifully,...yet nothing on screen! I'm really frustrated now. What do I do?
 


It's actually the window password. I've been using syskey to protect my computer. Now it prevents me to log in too! It seems like someone/something has changed my password. Virus perhaps? Now the most ridiculous thing is my pc receives power but doesn't show anything on screen, even the mobo logo. Just completely black.
 
From what I can find, if you didn't create a backup of the startup key on a floppy disk, then you're out of luck. If you did, you should be able to boot with that floppy inserted. I'm not 100% certain that this will work since your screen isn't displaying POST information, but from what I can find online I think it's your only hope at this point.
 


No, I am not. The screen is just completely black from the beginning to the end, even though the pc runs like crazy.
