random restarts & black screens

Hi, I have a problem with my laptop. I have windows 7 x64 installed but i also had this problem with windows vista x64. Randomly it will either restart or black screen (with the power light still on). There is no real pattern to this and hasn't happened for 14 to 15 days until i used it yesterday (3), and has happened today (2) also.

I checked in event viewer and this is what it said:

Hi,

I can't seem to find it . It should be in C:\windows\minidump? Also tried searching for it as well but nothing. I looked in system then start up and recovery and it's set to "write an even to the system log" at the location of %SystemRoot%\MEMORY.DMP

Never had a blue screen on my laptop, if it doesn't restart it black screens (i don't know if that helps).

So i tried to change the location just in case there was something wrong but every time i did it said the location doesn't exsist. So i left it as default.

Update. I've installed the latest graphics card drivers (beta) for my radeon mobilty hd 4650. I did have the "latest" ones from the windows update but i've had issues on my other computer before. Also when i've been on the ati website before now it said it didn't support this mobilty card and to contact the manufacturer.

My specs are:
Laptop
Intel core 2 duo cpu p8700 2.53GHz
4.00GB
Windows 7 x64
Radeon Mobility HD 4650

Update: It's happened twice today, in the space of say 20 mins. The first time it happened (when i had vista installed) i thought it might be overheating, which makes sense but it's been 13 to 14 days since it's happened this month. That's with it being used everyday

Ok i've done what you've said and i'm just waiting for it to happen again, then i will post the dump in a .zip file

I'm really confused now, it happened again and i did exactly what the instructions said. But nothing in c:\windows as a file or a folder. Any suggestions?

Nope, nothing there. Not even a folder. Does this mean it's not crashing?
