Windows 7: Very slow performance, IRQ conflicts ?

Windows 7 Professional 32 Bits
Very slow performance, IRQ conflicts ?


This is my very first thread on these forums and I hope you guys can fix my issue.
I own an ASUS G1 laptop that I use for gaming, especially online gaming. The laptop itself dates back to 2007 therefore it came in with Vista pre installed. The performance was good there, both offline and online but somehow I wanted to give Windows 7 Professional a try, and there began the issues.

Overall the performance is very bad ; I encounter many lags, audio stuterring while browsing, mouse lag, applications taking ages to launch, bad fps. On games that should run fine (that my laptop should handle without any problem), I've noticed that the framerates are decent offline but whenever I join a server online, I get hugefps drops.
This solution partly helped : "lag" in online games with Windows 7 - by disabling network throttling on multimedia class scheduler, I've managed to reduce fps drops online, but the issue ain't gone completely, and my overall performance remained low, gaming aside.

Someone just told me about hypothetical IRQ conflicts ; I had never heard about it, but checked Device Manager and here is what I've found :

Is it normal to have so many ISA lines ? Is it normal to have 3 devices sharing same IRQ (16) ?

Sorry for my lack of knowledge, I'm kinda new to this. Hope you can help, would be much appreciated !
