My Acer Aspire 5750g has been extremely reliable. All of a sudden it's had this problem.
A few days ago my laptop when dead, so I charged it up and pressed power and the "Acer" logo comes up, flashes black with a little dash ( - ) that flashes then it reboots back to the Acer screen and restarts the process over and over again. Basically, my laptop is stuck in boot!
When i turn it on, it shows "press f2 key for setup" and "f12" for boot options. Ive explored both of these keys and nothing has worked. Except when pressing a boot option in "f12" menu, it displayed a message saying "Media Test Failure, Check Cable" on boot.
What is going on? Is my HDD dead?
PLease please please help! I've never had Acer problems until now 
exactly you had:
PXE-E61: Media test failure, check cable
or just
Media test failure, check cable
in the first case is enabled the boot from LAN and disabling can solve the issue.
in the second, you need to contact your regional Acer support .

PXE error message appears when BIOS is attempting a boot from LAN.
on your BIOS please disable any Boot from LAN and, if available, disable ROM PXE loading at boot.
if this doesn't work, try to find an option like "load optimized default" or "restore default options" on BIOS and re-try to boot.
which BIOS version is on your system?
1.21 is the latest:
