Forces alt+tabbing?

[SpaceFalcon]

Hi I have a

3.0ghz Pentium4
PM800-M2 mobo
RadeonXT x1600 512mb
180GB HDD
1024GB RAM
And a basic microsoft keyboard and mouse..

Um problem here is my games and videos FORCES alt+tab it doesen't create a popup so it goes into windows or nothing just alt+tabs for absolutly no reason? this is a problem it happens every now and then and really ruins me in games cause I just stand there and get shot and die.. this happens every minute to 20 minutes.. just randomly.

It also occurs in videos as well just goes into window mode on videos, I have tried reformating, tried other video cards.. and i'm using Omega drivers not sure if it will work with ATI official drivers because those don't work for me. for some reason.

Does anyone know what the problem is I really hate to bring this to a technision so he can run Ad-Aware.. and yes i've done alot of virus scanning myself.

Thanks for any help.

Forces alt+tab? what exactly is it doing ....not getting what you are trying to explain ...you don't run ad-aware?

Ad-aware:

CCleaner:

What anti-virus?

I've used those

Ad-aware/Spybot/Antivir/AVG/BPS Spyware remover/CC cleaner

Probably a ton more.

Could be my keyboard but I've had it for years and never had a problem with it.

Nothing in event viewer the only unushal thing i'm noticing is that i'm getting bombed with these ads.

I keep clicking cancel but the ads keep coming up and it points me to a website prompting me to download driver cleaner :

These ads come up every few minutes.
