yep, never overclocked it although im using Omega drive. didn't install the OC feature. even removed both covers of casing to allow more air flow.
here's what i found from the log file of ATI Tool:

2006-09-12 11:38:34 ATITool v0.24 started.
2006-09-12 11:38:34 Detected GPU Chip: R350 (4E48), 8 Pipelines, 128 MB
2006-09-12 11:38:34 Temperature monitoring: chip not detected

yep, definitely 533fsb. is it not good enough to support radeon 9800 pro?

so the real problem here is the PSU rite?

ltw82, im downloading Everest now. will give the temperature read later. thanx.

i've checked the BIOS just now, and couldn't find the Choose Compatible Mode.

now im quite worry that i might spoil the card as a consequence of using unsuitable PSU. only played CS 1.6 couple of times before as i just bought it last Sunday. what's the sign of broken gc? should i unplug the card till i get new PSU? it's not a cheap gc at all, at least not to me.

i've tried for so many times, and still couldn't find the CPU Compatible Mode. maybe i got an outdated bios. never flashed since i bought it back in late 2003.

guess the only solution now is to find better PSU rite?

guys, i've reapplied the thermal paste on the card/GPU, but that still didn't solve the freezing/hang problem. i played CS 1.6 and Source for about 1-2 hours and then started to freeze again. i checked the heatsink and found out that it was quite hot as it used to during freeze. could this be a problem from the card itself? is the stock cooling on radeon 9800 pro not good enough to handle the heat from games like CS 1.6?

for the info, i've removed both sides of my pc case to allow more airflow, and only play games at night, with the air conditioning on. i also tried to use different ATI drivers including Omega and Catalyst 6.7 and 6.8, and i've never overclocked it, not even once. but the freezing problem still exists.

question is now, do i have the right to return the card to the seller and ask him to make full refund to me? personal warranty will expire by tomorrow.
