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.
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.)
