Windows 7 – How to Fix Chrome Lockups on 64-bit Systems

Judging by what you posted temp and cooling wise your computer is overheating and that's the first thing to rectify. 64 C on an idle load is not acceptable and isn't really preferred with a full load. I'm a little paranoid and freak out whenever my CPU get over 35, but really 50 should be your max on a load.

Invest in a good cooling solution for your system. A pretty decent system will only set you back 20 to 30 dollars. If you are looking for some help on what to look for take a look at this Tom's Hardware review of sub $40 cooling solutions.

Also you might want to enable your Blue Screen of Death (as terrible as that sounds) so that you can debug the problematic lockups. This is done by:

--> right clicking on "Computer" from the start menu

--> Select "Properties"

--> Select "Advanced System Settings"

--> Select the "Advanced" Tab

--> Select the "Startup and Recovery"

--> Make sure that "Write an event to the system log" is enabled.

Sometimes there are cleaners that automatically stop BSOD's from recording (Advanced System Care) and you might want to look into preventing that. Once you've checked this issue, then I suggest using NirSoft's BlueScreenView to view the crash details/debug related issues.

Finally, I would check and recheck your PC and ALL of your connections. I actually had a similar situation and found out that one of the internal motherboard USB cables was incorrectly connected, thus causing issues.

Update

I have put together some questions for general troubleshooting and diagnosis of crashes or freezes. Please refer to them as well, as they may also help you in your search for the issue.

• Forcing a crash to create a dump

• Troubleshooting via Dump reports

• Troubleshooting hardware related crashes

Exit Chrome, navigate to your User Data folder (eg C:\Users\IanN\AppData\Local\Google\Chrome\User Data\Default), then open the file Preferences and look for the following section

"browser": {
   .
   . <there will likely be a few sections here>
   .
   "window_placement": {
      "bottom": 1149,
      "left": 0,
      "maximized": false,
      "right": 1600,
      "top": 406,
      "work_area_bottom": 1149,
      "work_area_left": 0,
      "work_area_right": 1600,
      "work_area_top": 0
   },
   .
   .
   .
},…

Either adjust the number, or just delete the whole window_placement block—make sure to be careful not to delete other stuff; use the curly-braces as guides and make sure to match them. (Make a backup copy of the file, just in case.)

Now run Chrome. It should be displayed in the default location. If not, then you could delete the other window_placement_* blocks from Preferences and …\User Data\Local State (Local State is a file in the parent folder of Default.)
