after I just installed windows 7 and rebooted after installed updates and drivers, I get a black screen with the mouse cursor working, but nothing happens. I cant get past this, after ´starting windows´icon, the black screen comes up with the mouse and nothing is responding. I have tried everything, F10 and system restore and CMD and boot repair and removing battery, and safe mode does not work either, and I tried to connect another monitor but the screen shows the same black screen with the mouse cursor at every boot I try .
I am not able to enter bios. I press F2 but no bios, and pressing F12 does not work either. And pressing alt+ F10 only gives : /NOEXECUTE=OPTION, and some texts. I cant boot from the windows disk either since I cant choose boot options.
There is nothing wrong with the hardware for sure. I just have a black screen with the mouse cursor, I have tried everything, all sorts of command lines in CMD, nothing gets me back to windows.
I have tried to get it to boot up to CD drive so I can reinstall, but as I said, cant go to bios or F12 or ALT+f10, and I dont have backup, just istalled windows 7 and all was well, windows update for drivers, reboot then boom, this happens and I been stuck for days now. has to be an update that made this happen. can anyone pease help me ? 
acer aspire V5-531 series.
