Update :
Ok. The problem with cold starts freezing on the 'Abit' screen is due to the USB ports at the rear. With no wire plugged in, my pc starts up just fine.

Problem No. 2 : PC freezing up in the middle of nothin, and popping-up the 'New jack inserted' dialog box - somehow even this has been sorted out half way - the popup doesnt show up now and frequency of freezing has gone down - to almost once in 2 Hrs. No idea why it happened/ happens and how it was rectified the half way.

And now, one of my stupid doubts. I checked up in the properties tab for'My Computer' twice or thrice today - and somehow it shows the Q6600 to work at 1.8 GHz only. Why is that so, when i am not using any power-saver settings. And if there are any settings applied by default - how should i change them ??

Is it because my PSU ( coolerMaster 600W ) seems to be in-adequate ( as per calculation provided in some post on this forum, it comes to 500W ) ??
