Laptop Freezes (completely locks up) when playing a video

[swiftylol]

The Problem:

- This first started occurring on Monday the 24th, I played a youtube video on Firefox and the video lagged with a black screen on the first 1-2 seconds of the video. At around 3 seconds, everything stopped. My cursor, the video, the whole laptop etc. The time was no longer moving on the video and my system time wasn't changing either so I concluded that my laptop was frozen. I waited it out and there was nothing I could do but hold down the power button in an attempt to try and turn it off.

- At this point I'm still able to watch youtube videos on chrome perfectly, however... Playing a video file from my Hard drive produces the same problem. I've tried playing files from both WMP and VLC player, and the same thing happened both times.

What I've tried:

- Uninstalled and then re-installed my display driver
- I tried a system restore yesterday and got a BSOD before my laptop even got to shut down
- I did a successful system restore to the 22nd via safe mode
- Searched the web for solutions but couldn't find anything

What I'm considering:

-Reinstalling windows (I'm in the middle of doing uni work atm so I'm trying to avoid this)
-Buying a new laptop (When I get the money)

May be useful:
-I was getting quite a few "Low RAM" messages from the system on the day that it first occurred, before it first occurred. Haven't seen anymore of them, however.
-Playing 3GP and MP3 files on WMP is fine

I really appreciate any help and if there's anything missing from my post, please let me know and I'll try and get back as soon as I can.

Hello swifty and welcome to Seven Forums.

Just for confirmation, you were able to do a successful system restore to 12/22. However, you are still unable to play a video from the hard drive using WMP or VLC. And you still can't watch You Tube videos while using Firefox. When you uninstalled/reinstalled your display driver, did you get the latest driver directly fom Dell? Did you make use of their diagnostics?

I don't know if this will be of any use, however I had that problem a while back, the videos would stop playing at a certain point & the entire PC froze up. As it turned out, I had just installed some new RAM I ordered & as soon as I put the old back in, the problem ceased. My lock ups were caused by a bad RAM stick I got, but it only locked up when I attempted to watch video. I didn't notice a problem with anything else. Odd one for the books...

Anyway, might want to try that if you have some extra RAM lying around, swap it out & see if you still have a problem...
