Freezing - Music&Video Jamming... HELP!

[beambeam]

Symptoms:

If I play Media Player, Real Player, Internet TV/Radio on Winamp, Sonicstage or indeed any style of media player, it keeps randomly jumping and distorting on tracks and that, like a dodgy cd if you must...

At the same time, if I am online and scrolling down a screen or what like, the screen freezes and distorts also...

Best way I can describe it is like someone with a nervous twitch?

Now I have ran Norton, SpySweeper and AdAware scanners and all seems to be clear!

No corrupted files either as its happened with all 6 DVD's we've rented from BlockBuster this week and on brand new CD's!

ANY IDEAS what is causing this? It happened before but sorted itself out! Now it's back again!

In case it helps it's a few months old Sony Vaio PCG-GRT996VP

After this, I will request help with settings on my firewall etc but thats another thing, it's no good surely just switching it off so I can use Apps online etc etc... being behind the University LAN firewall doesn't reassure me either!

Thanks for any help, suggestions in advance!

Just installed the drivers update for it on the Vaio Support Link Site and still no change... its happening a lot still and is getting very frustrating!

Did you update the BIOS?
Have you made major changes?
Is this a new thing or has it been happening since purchase?

Update Bios? Unsure of this, can you explain further please? Cheers

Major chnages such as? I have only had this laptop since february

The BIOS is the heart of the PC, as you do not know what it is - it's likely you haven't changed it, so that's good.

As for major changes I mean Service Packs, AV software, Drivers, Firmware etc.

No - definitely havn't tampered with the BIOS!

Changes - lastnight I installed the update for driver found on the Vaio Link - everything was done vai the step by step instructions and done proper - no change in the situation.

Firmware? Such as?

Sorry if I come across relatively dumb on certain topics, not very experienced with the gritty stuff in PC's!

What did you install?
Don't worry about firmware, this is for updating hardware.

I installed::

NVIDIA GeForce FX Go5600 Graphics Adapter Driver

Lastnight, no difference at all - also installed the Vaio Update available for it...

both were sourced from www.vaio-link.com

Try system restore to see if it makes a difference.

Rightio - will I lose anything at all?

How do I go about this, done it once vai a mate helping me on MSN but that was ages ago and on my old laptop

Go to start > All Programs > Accessories > System Tools > System Restore.
Click on the last restore point and revert to that.
