when i play games after a while my comp restarts itself. I have been told that it may be the graphic card overheating. My graphic card is a ECS 9800gt. Temps get to around 73 degrees when playing games. If i need cooling how should I cool the graphic card and what products should be used.
Thanks in advance

Oh my another 8/9800gt overheating thread. :D 

Tbh, 73C under load is nothing for the gpu itself, but it might be overheating the rest of your system. My 8800gt idled at 75C/90+ load and ran games fine until the fan failed.

You might want to look at your overall system temps instead of just the graphics card. Buy a cheap pci extractor fan from newegg, they cost buttons and can really help to draw heat out of poorly ventilated systems.

73 seems a little high to me.

What kind of case are you using, what cooling solutions are you implementing?

What kind of power supply are you using (brand and model)?

Not sure what case it is the brand is CWORLD who built the computer. The case doesn't allow a lot of airflow and has one small fan on side panel. I have a 450w power supply from CWORLD

I had a bad stick of ram that caused the same problem once. PC only would restart while gaming. I had used that memory for a few months before the problem started, so it took a while to figure it out.

Restarts during gaming are also a sign of an inadequate power supply.

You probably have a cheap, generic PSU.

Computer never restarted when I had my old 7600 gt in it.

A 7600GT doesn't require as much as your new card. The 9800 could have pushed it too far and your pretty weak PSU can't keep it supplied with enough stable current. I'd swap the PSU.

Also just for good measure if your GPU is getting too hot it's more likely just to throttle it's frequency back rather than your whole PC re-starting. I still think your PSU is at fault.

I think I agree with the PSU, but also while you are at it, I say add a pci slot cooling fan to put below the graphics card. That should help pull some heat off your card.

I also have the same problems: i can benchmark it 100% fine and completes every time and play Farcry2 on max res but some game will cause a freeze and reboot, i have been told many times its the PSU. I found a Corsair Power supply 620W and i'm waiting till i can order it.

Need to know what other components we're dealing with here to recommend a proper PSU, however I would bet that most (preferably reputable name-brand) ones with at least 500W (continuous) or 600+W (peak) would suit you just fine. Another thing to consider is the number and type (6-pin, 8-pin, 6+2-pin) of PCI-E power connectors and number of SATA power connectors needed. A lot of people overlook that little tidbit.

On my power supply box it says ATX 550 wat. On the documents the salesperson gave me it says 450 watt.

Open the case and see what the actual power supply says. What's the Make/Model on it? What are all the power ratings? Maybe take a pic and post it if you can...

It's easy to assume your 7600GT didn't have this problem because it doesn't require/draw nearly as much power as a 9800GT does under game conditions.
