Can everyone help me to solve the annoying problems about games?

Hi Tom's hardware community,
With all my effort, I have just purchased the new system built by my own.The specification is:
Intel Core i5 2300 2.8Ghz
Asus P8H67-V
Corsair 2*2GB XMS bus 1333mhz
Asus EAH 6850 Direct CUt
PSU Corsair CX430V2
LCD Viewsonic VA2038wm-LED
The purpose of buying this system is to play the latest games in 2011.
However, I have experienced some problems with the old games:
1. In StarCraft II, when i played the Campaign, several times the screen went black and then an announcement appear "No signal", although I could still listen to Mr Jimmy Raynor's speech! I had to press Restart, but after I restarted, everything became normal. Sometimes this problem happened even on Desktop Screen!
This phenomena did not appear with my old Samsung 740N, but turned up when I used the new Viewsonic one!
2. Besides losing signal, my system occasionally freezed when I played some hard games like Crysis 2, Crysis Warhead, SCII. But freeze did not happen in Dawn of War II Chaos Rising, Fifa 11, or some other slight games.
3. Sometimes the whole screen went dark, the only left were some white lines across the screen.
(Sorry I cannot post some evidence pictures, and for my E too 😀 )

I have sent the GPU back to the maintenance department of the company I bought the system, but they said that it was fine, because they could play PES 2011 in 2 days without any bugs!

Can any professional give me an advice to figure out that matters? I do not want to spend a large amount of money for a buggy system!
Thanks everyone 😍

Did you ever check the ram to make sure it was configured properly in the bios?

Yes, I checked it carefully. It all matched the case latency.

And the voltage? Not enough voltage for X settings will result in instability.

Close Wamphryi, but you need more studying on PSUs. His PSU is fine.

OP, you said the problem went away with a different monitor? Perhaps the one you are using is bad, or its a bad cable.

You are correct sir +1

On one of Toms HWs SBM builds, one of the recent 500 dollars ones, July 2011, it had an oc'ed AMD quad and a 6850 that ran 100% perfectly fine on an antec earthwatts 380w psu. The direct cu may only draw a tiny bit more power if its oc'ed but even the 380w provided oc headroom to the build:

alright Ill dig it up here it is, OP check this config: your psu should be fine:

here is the part where they talk about the psu:

Yeah, everything's just fine! I'm testing the whole system now

Thanks for giving me a very useful example

your welcome, it just goes to show that your current psu is fine for your rig and your incoming gpu

Hopefully things continue to work fine.

When you have problems like that the first step is to double check the ram settings. If they are correct, running Memtest would be the next one. All it takes is one bad stick...

^so true
