Computer crashes (freezes) randomly.

Returned system to Acer 3x now. still same problem.FREEZES. Win7 installed. added HDD inspector for HDD temp. removed HDD cover, 6"fan directly on system, unit raised 1.25" with plastic raiser.

this was to allow only 4 Auto updates. HDD temp 90*, this time all updates passed. next will attempt Office 2010 Pro Full install, with same method. normal install has failed 3 times.

Retired computer-elec tech. many thing to try... will keep posting back.

Snuffy

Today ran some tests. removed memory cover, removed hdd cover,using usb - started installation of Office-2010 Pro. monitored HDD temp, max - 102 no enough to kill. installation went 100%. replaced HDD cover & still again repair installation 100%. so far i see the backing over the memory cover does not allow heat removal. I'll remove the hard backing & replace with cloth...

1. It is 100% clean of Virus - guaranteed

2. power supply is quite big - no problem there

3. I use the WORK METHOD to test for FREEZE UP. insert a USB and either CLEAN install Office(full)SP1(1.21GB) or DL massive upgrades from MS... before removal of heat shield from MEMORY i could FREEZE very easy.. from 1983 to day 99% for me FREEZE is memory or CPU heat problem. test has been working CPU Memory and HDDs - hince UPDATE or DL at max - monitor is easy to see if working hard.

removal of cover - now can DL over 4GB max NoProblem, Installed Office 2010 - NoProblem, 1st time HDD ever went to 110* w/o freeze.

There are NO ACCESSORIES on this UNIT.

I think I have found the fix - open display and change to Win7 Basic.

a. Memtestx86 over 9 hrs - NO ERRORS

b. WD Diag HDD and ALL TESTS - PASS.

c. opened Display and changed theme to Win7 Basic .. No more errors, today. no fans used, plenty of heat... HDD temp over 112*, memory warm to touch. NO ERRORS...

Sounds normal. I finally disabled AERO. No Freeze up since.

Thanks to all the others whom have offered. Take the Battery out , changed PWR Supply, swapped memory swapped HDDS. the only thing I have to do is DISABLE AERO. then NO FREEZES but the sound is distorted.(I can live with that.)

There are different steps you can take to fix your computer after it has been frozen. If your computer freezes while you’re running an application, but your mouse is still operation, you should press CTRL + ALT + DEL. This will bring up your task manager. Go to the application that is frozen and forcibly shut it down.

In the event that your computer is locked completely and it doesn’t respond at all, even when you do the above, then you should hold down the power button and perform a manual shut down on your computer. You should note that any unsaved data that you may have had before the shutdown will be lost. It’s always important to automatically save or back up your data in case of an emergency.

The final fix to your computer crash should only be done as a last resort. Your computer may have had an important system file deleted or corrupted beyond repair. In this case the only thing you can do is a system restore.

A system restore will essentially reset your computer operating system to the way it was a few weeks or even months ago. You can set it back to a time when the computer was running smoothly. Note that anything that you created or downloaded before the system restore will be lost forever, so backup any important files.

After replacing the Memory with a NEW Non Samsung Chip. Computer started with NO problems, I also got a new clean install....

Never had another Problem.... never froze, works perfect.... so nice my neighbor bought it for his GrandDaughter, who uses it every day and

Seen GrandDad this AM.... says the little Acer is so nice he also bought his Wife a New Acer for Christmas because the A0751 worked so nice.

Reference to the battery problem... by ehustus . M$ has admitted that they had a BAD and have offered a Battery Fix which reportedly has cured over 95% of all Battery Problems with all systems...

Hello to all the people, like me, who found this thread looking for a solution for their Acer computer randomly freezing.

I have an Acer Desktop and for the first few weeks, there were no issues. Everything was running fine when suddenly it started freezing and random times. It was difficult to pinpoint what the actual issue could be due to the randomness. There were multiple solutions online and none of them worked for me until I had the idea that it must be something set to run at certain times that is causing this. The next time the freeze happened I went to Task Scheduler when I restarted the computer to see what had run in the minutes leading up to the freeze and I did this every time for one day to really pinpoint it. I discovered that several ‘‘nv’’ tasks were running in the lead up to the freeze every time. I checked each one of their details and yes they were all set to run and random times throughout the day possibly overloading the system, I don’t know, but I set them all to run at the logon of any used instead and since then, now 4 days, I haven’t had a freeze whereas before this it was happening multiple times per day.

TL:DR … Monitor your Task Scheduler to see what is running in the leadup to the freeze and you might find the culprit. Don’t disable what you find as that might cause other issues. Instead set them to run only at the logon of any user. Can’t guarantee it will work for you but it has worked for me.
