When I try to start up my Aspire 5517 Hd laptop it goes straight to a message saying windows wont start and it has issues, a message then pops up and says it is repairing windows operating system, however after several hours it black screens and will not respond, so I have to completley shut down., its not giving error information or leaving a log, I went back to factory settings saving everything into a back up file in C, and was able to get back on, when I shut down or restart I have to do the same thing to get back in. I got into event viewer, but there is still no actual log, in even t viewer there are several events all the same ( Apti driver for NT is responding slwoer the expected to the resume request to this device: ACPI Driver for NT. Driver Version 6.1.7600.16385 Device name ACPI_HAL\Pnpoco8\o Device Friendly Name-Microsoft ACPI Compliant System Event ID 351 Task Category: Stand by performance monitoring My OS is windows 7 home basic.

Contact Acer as there seems to be a more serious problem with the machine. Vote if answered or helpful, I am running for Office (joke)! IT/Developer, Windows/Linux/Mainframe I also am a true vegan and I am very good with economics and I used to play chess at 2400++ I have lots of papers on my site for power supplies and video card problems, see the resources section

I dont know what I did exactly but I fixed it and its running better then when I first got it, no more warning messages or alerts., windows 7 was trying to up grade its self, and the ACPI drivers, why I'm not sure, I have all up dates on notify not automatic, but thanxs for the quick response.
