I just bought a used 2006 Acer Aspire T-180 desktop comp w/ windows 7 Premium.My first time using this OS. The screen was coming up Del: set up F 12: Boot Menu. I googled and it was suggested to unplug USB and power up and this seemed to correct the problem.
Everything was pretty much fine until this morning. A computer tech friend suggested to remove CMOS battery and reset BIOS. I planned on finding a copy of W7 OS and doing a clean install. I removed CMOS battery and put it back in after a couple of hours (nap time). Upon replacing, there were 2 continuous high pitched beeps and the Acer logo shows up for a second, disappears and I get black screen. I unplugged computer, removed CMOS battery again and held power button down for 20 seconds - put back CMOS battery, plugged in computer, rebooted. Now I hear 1 long 2 short beeps continuously. I made sure RAM was seated correctly, looked around and then noticed a flashing green power light in back of tower where the antennae for a D LINK sticks out. Activity wasn't lit, just Power light was flashing. I don't know if it's supposed to be doing that.
It was suggested that the former owner may have had a business set up and the D LINK was possibly password protected.
Any ideas of how I can get computer to reboot? Thanks
