GTA IV is not fully compatible with Win 7, read here http://forums.techarena.in/video-games/1108399.htm

Also, WTH are you running a 5770 with a i3 on a 15" monitor? Get a 17" at least. It's like running a speedboat inside a kiddie pool.

Whoa, glad this emergency got handle so quickly, was afraid someone might die!

But yeah, they are right, from HIS's website:

450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireXTM technology in dual mode)

Yeah, that supply has the 6 pin connection that will work on more every graphics card (it has two of these, so you can power 2 cards or a 1 newer nvidia card).

The cooler master GX series is crap, if you havent already bought it, dont. Get a good unit like an Antec EA500D, it will handle the 5770 with no problem, but stay away from the cooler master GX line up, they have significant ripple issues on the 650W and 750W unit, the 450W unit barely stays in spec, they are poor quality units but priced at the same level as much better units.

HardOCP gave the GX 650W unit a FAIL

Jonnyguru gave the GX 750 a 6 for performance on its first run through, and a 3 on its second because it failed to stay in spec

Hardware Secrets said this about the GX 750 "it is only safe to run this new Cooler Master unit up to 450 W."

Now, if the 750W unit can only stay in spec up until 450W, what makes you think the 550W is going to come anywhere near there? They used cheapo suscon capacitors and have a design that cannot output its rated wattage cleanly, how it made it through 80+ certification when it cannot stay inside the rather liberal ATX spec i dont know.
