Internal CD/DVD not recognizes by BIOS and Windows 7
My internal CD/DVD optical device is not working and is not recognized in BIOS and Windows. It is an ACER ASPIRE 5520 laptop running Windows 7 Home Premium and AMD Athlon Dual-Core TK-55 processor. The problem came while I was upgrading from Vista to 7. I have tried all the usual solutions like removing UpperFilters from the registery. There was no LowerFilters. I did the removing and reinstalling the device. I replaced the device with 2 used but functionning ones. I upgraded the BIOS. I installed Daemon Tools and created 2 virtual CdRom Device. Also, maybe of interest, when I go to BIOS, I can open the reader door with the button. As soon as Windows 7 start, I loose power. If I let the computer go to sleep, when I do wake it up, the device motor start to spin and the opening button doesn't work. If I use a pin to open it, the motor stop and if I close it, it start again. I need to restart the laptop to stop the motor. If I open the System Informations windows, under Software Environment, Driver System, at the Starting Mode column, it is written Deactivated for:
cdfs, CD/DVD File System Reader
crcdisk, Crcdisk Filter Driver
ws2ifsl Driver IFS Winsock
I hope those informations help find a solution.
Thank you in advance for your help.
