I have a Acer Aspire 5253 with windows 7 on it. I start the laptop and it acts as if it is going to load. Then suddenly the screen goes black and you can see the cursor but nothing else. I have tried the back up disc but it won't load it. I have changed the BIOS settings to boot from CDROM but still nothing. I have tried safe mode and once again it acts like it is going to load but then comes up blank with a black screen and cursor. I am unable to restore the computer since I can not run windows at all. Is there anything else I can try?
