PC Isn't stable

Hi,

I just got a new motherboard, CPU and RAM kit. I have;
Asus M4A88T-V Evo USB3 Board.
AMD Phenom 2.8Ghz 1055T
Corsair XMS 3 2x2gb RAM modules

Had a problem to start of, I turned on the PC and nothing would happen. Bios wouldn't display on the screen. Now It has passed that point and I can get into Windows now. However, after running GTA IV, the pc just sorta blanked out and stopped functioning. It just does it randomly. Can anyone think of the solution? I've checked the stickied thread and none seem to match my problem.

What are the rest of the PC specs?

Check the event viewer to see if it's logging errors.
Run memtest to check your RAM.
Download CPUZ, and make sure your RAM timings/voltages match the manufacturer's specs, and set in the BIOS.

Did you move your hard drive with windows already installed from your old computer to your new one?

Kernel-Power failure?

I haven't done a mem test yet but it was the same with two different types of RAM.
Timings are meant to be 9-9-9-24 but some how they are set to 8-8-8-20, could this be a problem? Voltage is fine, 1.65v.

To other post, I haven't done a clean sweep of Windows, that could be the problem and I am going to test that soon.

The Microsoft article here: http://support.microsoft.com/kb/2028504

States:
1. # Overclocking: Disable overclocking and see whether the issue happens when the system is run at the correct speed.
2. # Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is the same speed and that it is configured correctly in the system.
3. # Power Supply: Make sure that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices may require more energy than the current power supply can provide consistently.
4. # Overheating: Check whether the system is overheating by examining the internal temperature of the hardware.
5. # Defaults: Use system defaults, and run the system.

Change your timmings to 9-9-9-24 and see if that works.

1. I haven't intentionally done any overclocking.
2. Memory in my opinion shuold be alright because it does the exact same thing with another module.
3. Power supply could be a problem as it's only 700W. Yet, it still played GTA IV and still done a 'hard hang' when I disabled 3 cores.
4. I highly doubt it is overheating as there is ample amount of cooling. Antec 902, Corsair A50 CPU cooler and an ATI 4890 which is of course stock cooling.
5. I've not tried bios defaults yet.

Specs:
Antec 902
Asus M4A88T-V Evo USB3 board
AMD Phenom II X6 2.8Ghz 1055T processor
Corsair XMS3 2x2GB DDR3 9-9-9-24 1.65V
ATI 4890 1GB GDDR5
1x WD 320GB SATA HD
1x Sony Optiarc CD/DVD Drive

There is much under timings and I don't know which to change.

Well, It seems to have all of a sudden changed:S.

DRAM CAS# Latency 9
DRAM RAS# to CAS# Delay 9
DRAM RAS# PRE Time 9
DRAM RAS# ACT Time 24
DRAM READ to PRE Time 5
DRAM Row Cycle Time 34
DRAM WRITE recovery Time 10
DRAM RAS# to RAS# Delay 5

DRAM READ to WRITE Delay 8
DRAM WRITE to READ Delay(DD) 2
DRAM WRITE To READ Delay(SD) 5
DRAM WRITE To WRITE Timing 4
DRAM READ To READ Timing 4
DRAM REF Cycle Time 110
DRAM Refresh Rate 7.8
DRAM Command Rate 1T

Does CPUZ confirm those BIOS settings?

What OS is it?
February 4, 2011 7:08:59 PM

It is running Windows 7 Ultimate 64bit.

It's not wanting to boot at all right now, nothing is getting displayed on the screen.
February 4, 2011 7:10:42 PM

Any beep codes?
February 4, 2011 7:14:24 PM

No PC speaker installed :/ .
February 4, 2011 7:22:01 PM

Got a speaker from my old case. No beeps at all.
February 4, 2011 7:26:06 PM

Does your old case have a PSU? If yes, try swapping that in.

What is your current PSU?
February 4, 2011 7:30:30 PM

No, the old case is empty. My current PSU is the Arctic Power 700W. I managed to play GTA IV so I don't think it's a power supply problem and all the fans seem to power up on the PC.
February 4, 2011 7:35:36 PM

Okay, It just booted. I removed the 'Reset Switch' and the 'HD LED' cables.

You may have been able to play GTA, but that doesn't mean the PSU is stable. A failing PSU is a main cause of the kind of issues you're seeing.

It takes very little power to run those fans.
February 4, 2011 7:47:07 PM

I also disabled 3 cores and it still done the same thing :/ .
February 4, 2011 7:52:38 PM

That's still not going to affect the power draw much. CPUs don't pull that much power. And if the PSU is faulty, changing other settings isn't going to change the fact that the PSU is faulty.

I'm not saying that it is 100% sure the PSU. It's just a very likely culprit.
February 4, 2011 7:58:10 PM

Can you think of anything else other than that?
February 4, 2011 8:01:41 PM

It might be a loose power connection. Could be a failing motherboard.

Most other hardware will at least cause a beep code.
February 4, 2011 8:06:02 PM

It seems to be pretty stable now, touch wood. I think this has been the longest it has been on. I will check for slack power cables if it fails again. If it was though? Wouldn't you think it would completely shut of the PC? Because the PC just displays a black screen and you can't even turn on the NUM Lock.
February 4, 2011 8:08:15 PM

I also just noticed I have missed some screws on the motherboard, there is stand-offs underneath, could that be a possible problem?
February 4, 2011 8:22:02 PM

Running Prime 95 atm. Everything good so far :) .
February 4, 2011 8:37:59 PM

There isn't supposed to be standoffs under every hole. If you're using brass standoffs, they are only under the holes with the metal soldering around the holes. If you're using plastic standoffs, then they go under the holes without the metal soldering. If some are missing, but in the right hole, it's wont harm anything. It just won't provide the same support.

If the PC hasn't POSTed, then the keyboard wouldn't have initialized yet. So the number lock wouldn't come on.
February 4, 2011 9:31:53 PM

I have brass standoffs under all motherboard holes but there is two without screws.

I have been running Prime 95 for an hour and it hasn't crashed yet, looks like the reset or HD LED was shorting it.

When It does hang, regardless how long you wait, they keyboard doesn't initialize at all.
