Laptop freezing

J_B

My laptop - Acer 5741Z - 6GB RAM - Win7
occasionally freezes for no reason, everything just hangs for about 30 (?) seconds, then it seems ok again.

I regularly run CCleaner and Malwarebytes, use Avast AV and Win Defender

I downloaded 'autoruns' , but can't really make sense of it.

Any suggestions as to what may be bugging my machine??

Worst case - hard disk on its way out so check you have important data backed up. Then, schedule a disk check.

might be the drive.
try running the PC in safe mode for a bit and see if it also freezes on you:

http://windows.microsoft.com/en-gb/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7

If not then it might be a software issue. (worst case reinstall Win 7)

You can then use "msconfig" (go to start and search for it.)
you can then stop things loading at start up to see if that fixes the problem.

If it still freezes in safe mode then do a full BACKUP and create a system RESTORE disk, and buy a new hdd.. ^_^

Firefox? Just done a fresh install of Win 7 64bit and Firefox is using 100% of one of my CPU cores and 600mb+ of RAM.

1 Firefox window with 4 tabs open = 487MB?

Even if i leave Firefox on its default google home page it sometimes hogs the CPU.

Fresh install so barely anything on here. Adblock plus and Noscript and classic themes restorer.
Avast addon is disabled.

Also try running a system file check, it'll only take a short time and is worth doing. Type in cmd into run, then type sfc /scannow (note space). It might help.

Tried backing up to dropbox, but it's full now!!!!

Will dig out external HDD later today and do so then ...

Backup done - how do I 'schedule a disk check'?

It doesn't really happen that often, maybe once or twice a day .... don't really want to run in safe mode all day for that

That's why I asked about 'Autoruns'

I can do that with CCleaner
The only thing that loads in windows is Avast

CMD and then 'run as administrator'?
'didn't find any integrity violations'

Not a problem I believe. And no bad sectors. I assume the computer restarted ok!?
