AMD/ATI Radeon HD 6450 1 GB graphic card for HDMI out for Windows xp OS, Dual Core Processor , Intel DG41RQI Motherboard

I zeroed-in on

His Fan AMD/ATI Radeon HD 6450 1 GB graphic card. as it has fan , so for cooling.

but I see only that It supports windows 7 only.

Where as I have read that

Powercooler supports windows XP also.

I wish to know whether I can get drivers for

His Fan AMD/ATI Radeon HD 6450 for windows xp- 32 bit also.
also can I run two different applications, one on hd tv, and one on normal monitor with the
His Fan AMD/ATI Radeon HD 6450
or
Powercooler AMD/ATI Radeon HD 6450?

will my 1GB ddr2 SDRAM will be fine?or I need more?

Without fan , His 6450 Hd is not available in India.
with fan costs Rs.2700/-. His 5450 Costs Rs 2200/- . Even that also has fan.

without Fan HD 6450 is there in Autralia on ebay . and costs 70 Aus $. which Rs 4508/-.

I bought with fan 6450 (His) in india . and yesterday i installed on my computer.

Everything is fine. except that, thru HDMI, from computer , only video is coming , and audio is not coming.
what should i do about it. or audio won't come. also.

system is saying that , it is not able to find a driver for "SM Bus Controller."

some where else in this site i read about AMD forgetting about "SM Bus Controller" driver.

now in my case.
I want to know where might be my "SM Bus Controller".

in my inbuilt "Intel Graphic Accelator Chip" or in my "His 6450 HD AMD/ATI Radeon 1GB Graphic card."

for which I should load the driver. the system says , the driver is not on the cd-rom provided along with graphic card.

so is it intel's? or AMD forgot about SM Bus Controller Driver?

if it is Intel's , downloading it from intel site (my mother board is DG41RQI) ( I have the mother board cd with me)
(how to get only sm bus cntroller driver only?)

and installing it will affect the graphic card (driver)?

as the instruction in graphic card installation said remove any graphic driver.

Please give me a solution.

Thanks in advance.

No. I took it from the cd-rom they gave me. as mine is windows-xp, and its given that , windows xp , is there in that cd-rom , i went for the cd-rom. as you have said before, all drivers are from amd only , if windows xp were not there in cd - rom , i would definetly have gone for amd site.

so we can't tell it is actually amd sm bus or intel sm bus , the system is talking about or can we find out by any means?

so I' still not sure whether it is AMD SM Bus Controller or Intel SM BUs controller.

if it is AMD's , is it my windows xp sp3 that is giving problem?
how can I solve this?
well not any particular problem because of that now.
has to check Smart TV Audio signal is received from graphic card or not though?

Please don't take my data as more than necessary. I don't know what is necessary.

I tried 3 to 5 drivers of AMD SM bus (old though) for some , my anti virus is raising trojan objections.

Thanks in advance.

Finally I figured out that , the SM Bus Controller is in my Intel Chipset , which is attached to My Intel Mother Board.
I loaded the chipset drivers from my motherboard drivers CD. The problem got fixed.
Again I took the latest drivers of that Intel Chipset of that particular MotherBoard from Intel site, and updated it.

And about sound from computer speakers only , not from Smart Tv, (when video is coming from PC), I saw some where else in TomsHardware site
about setting in windows control panel about audio output device and set it to my AMD RTI Card Audio out put. now sound is coming through hdmi port of audio card to tv through hdmi cable , and to TV speakers.

I can reset it to PC speakers just by resetting the audio ouput device option.

Thanks to TomsHardware site. and

thanks to "kirilmatthew" for answering/clearing my queries/doubts

and to all those who post and answer.

Thank you very much.
