Do you see any yellow marks ? If possible please take a snapshot of it. To take a snapshot press windows key and type snipping tool. This tool allows you to take snapshots and save it. Please upload the images to seven forums.
I am sorry to say that it is 2:25 AM here and I have work in morning unfortanatly I can not assist you until 12 hours from now.
The mouse lagging across the screen suggest to me a lack of video drivers BTW.
I'd say I'm a fairly advanced user of Windows, if that helps.
I've tried video drivers from everywhere and haven't seen a difference. I've tried Leshcats modified mobility drivers which run better than stock ones, Windows drivers, AMDs drivers, as well as HP's drivers.
Unfortunately, as with many other laptop manufacturers, HP restricts the ability to install video adapter drivers to HP ones only. With a bit of playing around I managed to get various types working, although none work with stopping this mysterious lagging/stutter.
I am on a fresh install of Windows 7 with the latest HP AMD drivers installed.
As I said above, after running the Latency checker, I noticed whenever I enabled/disabled my Network card, I noticed HUGE increases in latency. If it was enabled and I was on battery, it would instantly lag. As soon as I disabled the network card, ZERO lag.
I updated the Ralink 802.11n Wireless Network Card drivers to the latest ones from HP and I am happy to report thus far no lagging under the same tests prior to updating.
However, the latency test still shows red bars (3000 uS+) latency but the mouse does not lag. Ideally I'd like this fixed, but it works for now.
Cheers for the reply, look forward to hearing from you tomorrow.
