Hi everybody. I have an Aspire 8920G laptop. I have Windows Vista Home Premium preinstalled (with no installation nor recovery disks delivered). I accidently hit the arcade button on the cinedash panel, instead of the power button. The computer started directly up into arcade deluxe, after a short install. Nice feature I thought, and choose to exit arcade through the exit feature. Then I noticed that the computer prepared to hibernate, but instead it shut off after it finished. After turning the computer on, a small complaint about improper closing the computer popped up, and I choose to start windows normally. Now the boot loader ran, and when I expected the logon screen, instead I met a black screen with a working mouse cursor. I eventually had to force power down, since crtl alt delete didn't work. Since then, all boot options, safe mode etc leads to the same black screen. Vista looks like it's going to boot normally then goes to a black screen with a working mouse pointer. The hard disk light just pulses every couple seconds. I tried extracting the battery but it doesn't work. I tried to alt+f10 - Vista Recovery page, so it gives me menu called "Edit Boot Options". There is the path to winload.exe and this: "Partition: 2 Hard Disk: b8f0ffa4 [ /NOEXECUTE=OPTIN ]" That's all what I have when I press ALT + F10. I could type "Enter" = nothing happened "Esc" = shutdown the system "F8" = go to recovery page. Hit f8: Goes to a "Vista system recovery" or something like that, i'm not quite sure what its name was. Anyway it had about 6 options, including "Get windows to check for and correct the faults on your disk" in a little bit more high tech talk. And "Restore to a earlier point". Since the "Checking and correct faults" said it was recommended, i thought i'd go for that. It ran its tool, told me to click the restart button. Runs it again, tells me to restart again. And now it enters its final state - Its virtually dead :|. If i turn it on, it will go to the black screen, that talks about an improper shutdown, with the options for Safe Mode, Safe mode with networking.. etc. Any of these 4 options all result in the same black screen displaying only the mouse cursor. I was not trying to install or upgrade nothing, was not trying to change form vista to xp or so. I have not deleted any hidden partition (as far as I know...) Please, I need a solution. Thanks a lot in advance.
