Anyone experienced bluetooth problem with ASUS A42JA?

I managed to pair it with a sony erricson mw600 BT headset i bought 2day with A2DP enabled. I was using the BT headset for 1-2hrs today for music when I jz bought it, then used it on some skype calls later in the day for a couple of minutes. Suddenly, it started acting up on skype conversation with  frequent disconnection.

Well, I tried restarting my laptop and when it started, the pairing will not work anymore. Tried reinstalling my bluetooth headset many times and even resetting my headset but nth works. Even uninstalled and reinstall the drivers for BT270 on the laptop under device manager, nth works...

Then, I tried pairing my phone to my PC and again it doesn't work! However, b4 this incident, it works wonderfully for file transfer btw my phone and my laptop! My bluetooth headset is certainly not defective as it works fine when tried on my phone.

Now, i'm rly worried if it could b a bluetooth problem on my laptop. Its only 2 weeks old, any1 have any suggestion for any methods to verify this prob and if possible any fix for this? Haiz, I'm rly lost, bluetooth works OK for handphone b4 this and this problem showed up after using my BT headset and I can't get it 2 work anymore....   =(

TQ in advance for yr advices...
