    Running an Acer Aspire 5742 running Windows 7. It freezes intermittently. Does not crash just freezers, no blue screen or error message. The only way to access it is to hold down power button and reboot. I thought Windows might be corrupt. So I ran the recovery programme and re-installed to factory install. So a brand new install was done problem persists. IT seemd to happen when trying to access the internet especially windows update. As the problem persisted I replaced the hard drive and again a full install from the install disks I created. Still the problem persists.
    AS it seemed to happen when I accessed the internet I updated all the network card drivers. Problem still there.
    I then removed the wifi card from the laptop and run it from Lan only. Still freezes. I completely removed the LAN driver and fitted the WiFi card back, re-installed new WiFi driver. And it still froze. I have re-seated the RAM modules and tried new ones. No effect.
    Any ideas?

    My first guess is overheating.

    Is its exhaust fan(s) working and expelling the hot air from inside the case?

    Yes fan is on and appears to be clean as do the vents. If it was overheating wouldnt the laptop just power down?

    Just checked the fan isnt coming on, must be intermittent as it was when I checked earlier. Problem solved.

    The exhaust fan should not run continuously, but should cycle on and off as needed.

    Depending on the laptop model and the amount of overheating, it can either freeze up or shut down.

    We don't know how you use that laptop and what's installed and running in it, so that may have a bearing on the issue.

    Go here to download and save the portable version of Speccy in an empty folder.

    Extract its contents into that same folder.

    Double-click "Speccy64.exe" to load its main window, then wait for the scanning process to finish.

    Click "View - Options", then change the temperature to "Imperial (F)", then click OK.

    Keep Speccy's main window open while you use the laptop, then see if there's a big fluctuation or increase in temperatures.

    Those temperatures are fine for your laptop. (y)

    The temperatures in my Dell Precision M6400 WorkStation laptop fluctuate between 135 - 145 F, and it runs fine.

    So its a total mystery as to why it keeps freezing, its now been running an hour without freezing. Yet other times it can freeze after just a few minutes
