No dedicated GPU. This can fail under a gamer's load due to many things but let's forget that and ask a few questions.
1. I will assume it worked for years.
2. Are you using a laptop cooling pad?
3. Are you keeping up with the 1st of the month canned air to the vent work?
4. I will not repeat prior discussions about temps. This is not a gamer laptop but might do if we put it on the cooling pad and keep up the 1st of the month routine.
I'll try to keep this short but detailed.
Lately my computer has been randomly shutting off, as if I held the power button down, and restarting, without warning. This most commonly (or always) happens when I'm playing World of Warcraft, a very RAM-intensive game. Another forum I checked said that my fans, etc, might just need to be cleaned out, so I was trying to uncover my laptop to do that last night. I had to stop the process because of an activity I was attending on WoW, but my computer still rebooted while I was playing, however, one of these times, the computer started beeping and would not start the boot process (the screen stayed black).
At the time I was not aware of the actual location of my computer's speakers, and I thought the beeping was coming from a part, not from the computer itself, so later on (after the WoW event) I started messing with the part I thought the beeping was coming from. I looked it up and found the part to be my computer's RAM, which I then took out of the computer and attempted to boot it up, but the screen stayed black and the computer started beeping again, very similar to the time before when I hadn't taken out the RAM.
Having almost confirmed these were the issue, I did more research, and found a program called MemTest which I attempted to download but for some reason couldn't get to work. I then found out my computer has a very similar program already built-in (Windows Memory Diagnostic) and ran that program to do about 5 tests in total, but every time it said it didn't detect ANY issues with my RAM.
Is there possibly another cause for these issues?? Something besides my RAM? I run a Dell Inspiron 5520 with Windows 7, 6 GB RAM, 64-bit OS.
TL;DR: I had very good reason to believe my RAM was failing on my computer but Windows Memory Diagnostic found no issues. What could cause similar issues?
