random restarts & black screens

I'm starting to think it is overheating, but i don't know how to prove it! I've now got a cooler to put underneath the laptop (only cost £10 so i don't know if it works?).

My main concern is the fact that if it's overheating why is it not doing it all the time. Why only now and again and every 10-15 days? Any info would be great

I don't know what i'm looking for in this txt file, any help?

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

Not all crashes generate a dmp file, bu i suspect you need to configure you system control panel>advanced settings>start up and repair> enable writing as in the pic

I've done that, had it as kernal memory dump & also small memory dump (256KB). I'm not getting a mini dump file. The file i uploaded was a .NFO file i was asked to upload but I've labeled it wrong .

Did it again the other night, just cut out like it ran out of power. Still no memory dump file. Any ideas?

anybody?

Not Available (probably COMPAL Embedded System Control) ACPI\CPL0002\2&DABA3FF&1 The drivers for this device are not installed. Took me a while to sort the Bluetooth out, didn't have the new drivers for win 7.
ENE CIR Receiver ACPI\ENE0100\3&11583659&0 This device cannot start. Same with this

So the above i have sorted out and haven't had a problem but like i said they are random. Had them happening when i had vista installed with all the updated drivers installed. I thought it was over heating but i now have a cooling deck, the last time it happened it was on it. I've checked the vents and they are clear. And it is set not to restart.

The only thing I've changed is it's now on balanced power plan, it was on high performance and it hasn't happened since. If it was overheating would win7 write it in a memory dump?

Hey,
The good news is that the black screens have stopped . But I'm now having crash's, not like a win 98 crash where you can't move the mouse and the whole thing becomes unresponsive. It's just slowly but surely locking up, still functioning but what ever i do is making it worse.

When it happens i only know because when i try to open anything it will either not open it or open a window with nothing in it. Can open the start menu but can't access the options for shutting it down. Tried to restart but alt+ctrl+del doesn't do anything. So pressed the power button so it shut down, but it doesn't and black screens. I do get an error sound, but i can't see because it's black screen. Have had one recently but to do with bluetooth says something about a stack error?

Also had an error the first time this happened when i was playing dragon age, came up with something to do with the video card not being accessible but that was only when i tried to click on something.

I'm completely lost with this....
