Cannot Figure Out Why Computer Keeps Crashing. Please Help!

I recently built a custom gaming computer in anticipation for Guild Wars 2. This is my first time building a gaming computer (I have used prebuilt computers before and replaced components), so I am no expert on this.
Here are specs:

Motherboard: Gigabyte 990FXA-UD3
Processor: AMD FX-6200 (6 core 3.8GHz)
RAM: 4GB (2x2GB) Kingston Hyper X 240pin 1600
Video Card: ATI Radeon HD 7770
Power Supply: CoolerMaster GX 650watt
OS: Windows 7 (64bit)

After building the PC and installing programs ect I tried to play some games. The games would load up just fine, but after playing the game for a short time, the game would hit a very hard lag spike, usually lasting 5-20 seconds where the game would stop and sometimes cut to the desktop before either resuming the game or crashing.

I have already run some tests to try and find out what the problem is and I've found that my RAM is functioning (memtest86) and that my CPU and GPU temps are okay (~50C under load).

Thanks!

It can be your HD7770 that is faulty, can you try it in another computer?

Just tried to test the card in my old computer, but it wasn't compatible with my old system.
Is there any test I can get similar to memtest for my video card?

Not really but when it crashes does it give you a message that something was not responding!

The message I get when crashing is something along the lines of "the display driver stopped responding but has been recovered"

and I will run a GPU benchmark test

Have you tried installing the latest drivers or reinstalling drivers or installing older drivers?

Ran a benchmark test with Video Card Stability Test by Freestone Group and got 534. What does this number tell me?

Vsync settings on or off has sometimes fixed the display driver issue but if it does not I would RMA the card.

Changed the Vsync settings and still no different. The crash/lag seems to happen (not always this way) at the same time some in-game event happens such as large groups of Npcs spawning ect.

In the benchmark i got 159 (Nvidia GT 430, AMD sempron 3500+, 1 GB RAM, win7 x86).

Still lost about that, i think the higher the score the more stable....

Uninstall the current drivers in device manager (search it in start menu, go to display adapters, double click on your GPU, go to drivers and click uninstall drivers).

First find the old drivers (which version GPU have you got).

Well there seems to only be one driver as your GPU is new, try reinstalling the drivers, here is the site for your drivers- http://www.diamondmm.com/7770PE51GDD.php

Also uninstall the Catalyst control centre and anything else ATI related....

Guild Wars 2 comes out next week, so it is brand new. I have been testing my computer on games such as Killing Floor, ARMA 2, League of Legends, Minecraft, and Skyrim.

Also, I just uninstalled and reinstalled the Catalyst Control Centre. I still crash in game

all those games will lay waste to a puny little card and only 1gig of vram.

I only experience the crashes while playing games, yes.

Also, I have been able to run these games on my old pc which had a nVidia GTX 260 with 896mb and the games ran fine.

Settings were on mediums and lows for League, mediums and high for kiling floor, and low for skyrim. (shadows on all games at low)

As for resolution, games were played around 1280x720 or 1024x768 depending on the game

check bios and make sure hpet(high precision event timer is enabled. and set to your o.s bitrate. ie 32 for 32bit, 64 for 64bit... some newer boards just need it enabled and thy often just call it precision/pet mode or precision events.

Any other ideas of what the problem could be? I will be adding up the power demand for all of the parts on my system and then deciding if I need to upgrade my PSU. Thanks!

your power supply should be enough for what you're trying to run. what are you using for a monitor ? and did you go into the CCC and see that that's what it sees and at the right refresh rate ?

I am using an Olevia TV as a monitor. I believe it is a 24" (If not it is around there. I can go find the box somewhere if it makes a difference)

Check out customer reviews for your power supply on Newegg. There is quite a few bads on there.

uninstall/reinstall the drivers and include the CCC. It has to be there or something is wrong.

what is your TV ?,........ specs ? forget about the power supply for now.

Still having the driver stopped responding message? Motherboard BIOS updated? If so in both cases I would go ahead and RMA the card since it can be caused by faulty Vram.

when you said the settings I told you to look for aren't in the CCC it tells me something isn't installed right. Those settings have to be there or you didn't look in the right place or you need to reinstall the CCC.

but anyway, if one card works other doesn't, if you're convinced it's the card................ do what you think you need to do.

I have fixed the problem, the graphics card was bad (went to local electronics store and they let me test a new card in it. Proved successful)

Thank you guys for the help though!

Thought so! My experience with cards is that generally they work trouble free out of the box if everything is connected correctly, never had to do any tweaks to get a card to work!
