After doing research it turns out that my notebook PC has some kind of "hard hang" issue in which my laptop becomes unresponsive. 7/24/13
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. 7/31/13
I've owned a Compaq Pressario CQ62-225NR notebook for almost 3 years now and I've haven't had any problems with the laptop until now. While I was on vacation in Rhode Island the laptop would freeze/crash about 5-20 minuets in use and I immediately thought it was bad memory. When the laptop does crash/freeze I'm not able to move the mouse cursor nor does the lights on the caps lock,num lock, or scroll lock respond when I press their key. When I got back from Rhode Island I opened up the laptop's RAM slot, took out the memory, re-seated the memory, and started up my laptop. Same thing happened, so this time I tried to re-arrange the memory and even use other memory from my other laptops and still kept on crashing. I took the original RAM for the laptop, put it back in, and ran a memory diagnostics.
After finishing the memory diagnostics it showed that there was nothing wrong with the Laptop memory whatsoever. I then re-booted my laptop and used some of the HP diagnostics that you can use when you hit esc during boot-up and ran a full diagnostic on the laptop. The diagnostics showed that everything was working properly and I then immediately thought that I had a bad version of Windows so I backed-up my files and did a system restore. Even with the system restore my laptop still kept on crashing/freezing so I then did a complete re-installation of Windows 7. I was surprised that the notebook didn't freezing during the installation but after I completed the installation and after I began using windows it still kept on crashing.
At this point it was starting to get intimidating so I thought that I probably have some kind of hard drive failure so I took out the hard drive and used a different hard drive with Windows 7 on it. Yet again, the laptop crashed. 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 I used a different hard drive no software could be causing my laptop to crash/freeze and it had to be some kind of hardware issue not involving the memory or hard drive. At that point I tried reseting the bios back to it's default settings "even though I RARELY go to the bios" since I thought I might of went into the bios one day and set a setting that could be causing it to crash. After setting the bios to default, the laptop still kept on crashing/freezing during windows.
At that point I was down to my last option which was going to the Hewlett Packard website to scan my laptop for missing updates/drivers
which could be causing my laptop to crash. After having it scan my laptop I was only missing 1 important bios update and a couple of new driver
updates but even after installing though the notebook still keeps on crashing/freezing. I then went to the device manager to see if there were any updates on my laptop hardware such as sound/audio drivers and various others. I was able to update some but most were already up to date.
I'm really not sure what to do at this point, I've tried almost every solution possible with the people who have the same exact problem that I have but none seem to work. I'm not looking forward to bring my notebook PC to a computer repair shop so I'm on my last stand for this issue and posting this here on the forum. Please help thanks
EDIT: Also just to add if this helps, my laptop battery needs to be replace since sometimes on startup it mentions "Low battery capacity battery needs to be replaced.
