Compaq Pressario CQ62 notebook screen keeps freezing

@gregrocker

Like I have said before. "I then concluded that it wasn't a software issue since the laptop would even freeze/crash when I use Linux ubuntu/kubuntu/fedora/puppy/ and various other Linux distributions.". Since it has crashed in my other Linux distributions yes it is a hardware issue. After the re-install of windows 7 it didn't freeze after using it for a half an hour. Once a half an hour went by I started doing the important Windows updates including the optional ones. After the updates that was when my computer started crashing. I should also mention that my laptop has become unresponsive when I re-installed Windows 7 before. As for the RAM and Hard drive. yes I have ran HP diagnostics on both of them when I press esc during boot-up and I have also done a memory test in the bios as well. As for overheating, I used to have an overheating problem before until I cleaned out my fan with a compressed air duster for computers but at the time my laptop was still freezing/crashing. Also ever since my laptop hasn't been getting hot to the point when it does overheat and if it ever does when I go to boot up it would even say that my laptop has shut down due to overheating. But rarely sometimes it would say that my battery is under low capacity and needs to be replaced.

If the overheating continues and can be pinpointed as a cause then I would consider repasting the processor. Chances are there may be a video for doing this for your model or product line via Google.

Until then check all cables and connections, run the full booted RAM Test with Memtest86+ for 5-6 passes or overnight, test your HD with the maker's HD Diagnostic extended CD scan followed by a full Disk Check.

Stress test your CPU - Stress Test with Prime95 - Windows 7 Forums.

See if the problem continues after removing the battery.

Have you had any crashes so you can have the crash minidump file analyzed in our Crashes forum which often pinpoints the cause: Blue Screen of Death (BSOD) Posting Instructions - Windows 7 Forums

So apparently the only time my notebook DOESN'T freeze is when my laptop gets hot, but when my laptop isn't getting warm that's when it starts to become unresponsive/crash. It's been a while since I made this post and I want to see if anybody else out there has a solution to my problem. From now on whenever I would like to use my laptop I would have to run Prime95 since that's the only time when my PC doesn't crash.

The issue you described is sometimes also caused by a monitor problem on the CQ62 and similar models. Basically the monitor stops responding and the screen appears to have crashed because it is basically a "frozen" image of a previous moment on the screen (i.e. the screen has not refreshed and is unresponsive). When this is the case, usually you can press on the monitor screen on an area an inch or two above the hinges and the screen will return to normal. Sometimes this same problem leads to a white screen until the screen is pressed/pushed on in the same way described above. Another test of this situation is when you attach an external monitor to your laptop. The external monitor should work normally while the laptop monitor is still malfunctioning. I know this is posted much after original post, but I hope it helps someone. I don't know of a permanent fix other than possibly monitor or monitor cable repair.
