Mouse freezes, followed by system lag and mouse icon turns fuzzy *pics

[biertonco]

Hi all,
As the title says i occasionally get this problem. My computer qwill freeze for a few seconds followed by system lag which seems to get worse (freezing every few seconds/taking 2 seconds to recognise a click etc.). If i reset my computer it resolves the issue but i was hoping you guys may be able to give me more insight as to what the issue may be.

It nearly always happens when i am browsing in firefox. Have never had it happen to me during gaming etc. which is why i'm hesitant to believe it is to do with my GPU or it's drivers which are always kept up to date.

i have included pics of the cursor and what processes were running at the time of the freeze/lag

Hi,

Have had a similar problem a while back using a dual core and it was always Firefox using something like 50% of cpu useage but your screenie doesn't show any process using the cpu??!!.

When it happens again have a look at the performance tab to see if it is high then switch to processes and watch for about 30 seconds to see how the cpu useage alters and which service is using it. If you have scheduled tasks make sure they do not all correspond (ie) all to run at the same time and day and see that you are not running unneccesary applications in ther background.

The mouse corruption like that is classic GPU problem symptoms, although you'll need to do some trouble shooting to be certain.

You probably get it more with Firefox due to plugins like Flash being GPU accelerated.

Get Furmark and stress your machine for a bit, see if any issues pop up: http://www.ozone3d.net/benchmarks/fur/

After that - Memtest it and see if that throws anything up.

thank you i will try furmark. Admittedly i have just overclocked my GPU but i did get this problem when it was at default clocks too

Check your system event logs for any disk controller errors, do you have an SSD or a HDD?
