Acer 7741G constantly freezes / crashes

Well I've already scheduled my repair with Acer but was wondering what exactly is wrong with my laptop that's only a couple of months old.

Basically at random, can happen a few minute after I turn on my PC or 8+ hours after I'm using it, the computer will either freeze and become non-respondent or randomly crash and attempt to reboot.

On reboot the video card will continue to run for a second, then shut off, and nothing else runs while the screen is black.

I'm guessing it's either my hard drive malfunctioning, but I've run a bunch of disc checks and its supposedly fine and I don't get the warning about my hard drive about to die on bootup. Hoping its not a power supply or mobo issue because Acer is going to "repair" this unit, ship it back to me in a couple of weeks (how long does this take?) and nothing has changed.

Does anyone know what this issue probably is? Something specific to this model or just bad luck on my end?

 

You might test the hard drive with SeaTools for Windows using "Long Generic". Also, test the RAM with Memtest86+.

 

Well hopefully I don't jinx myself but I think I found my solution (been playing Portal 2 all day which was NOT possible for more than 20 minutes before crashing before today)

Turned off the AAM/APM (acoustic / power management) on the hard drive and I don't seem to be getting the freezing anymore while using the laptop. Evidently these two were some sort of failsafe in case I dropped my laptop but people have had issues with this without actually dropping their laptop.

 

Hello all,
I had a same issues on my Acer One 257 and I found solution here:
