Computer Freezes,motherboard Problem?

I built a new computer about a month ago and it was working fine until about a week or so ago. The specs are as follows: Biostar TA890-GXB HD motherboard,AMD Phenom II x6 2.8ghz 1055T processor,2x2gb of a-data 1600mhz gaming ram, and a ocz stealth xstream 500watt power supply. It started freezing while i was typing or working on something,everything would freeze keyboard, mouse,operating system. That would normally be after 30 minutes or more,but the time gradually became less and less until now where it does it every minute or the computer doesn't boot at all. When it does boot it comes up with a message and says "DQS training failed on previous boot,reverted to slower DRAM speed". I have tried taking each ram module out and running with the other in,but with no luck. I have also reset the bios to default and changed memory settings,which didnt work either. All the cpu and case fans are working and the cpu is not overheating. I have never overclocked the system. The system freezes wether it boots long enough to go into the operating system or wether im in the bios. Does anyone know what might cause this or have had similar problems?

Run Memtest86+ and see if it returns any errors.

I've had memory that was touchy with the mobo I picked and had to return it and get something else.

Since it just started happening recently, and it freezes up regardless if the OS is running or not, I would guess either the PSU isn't good enuff or yer mobo or ram is going out.

Sounds like a memory issue or not enough power, but I would think the 500watt PSU is plenty unless you have like 50 fans and 10 GPU's or some odd duck hardware configuration. Does it make any kind or weird beeps or long tones of any kind on boot? or just a normal post beep?

Do this though, to be sure. Unhook all HDD's from the board, then boot a live linux disc and do the memory test. If it freezes during the memory test, I'd say try new ram. If the problem continues, then there must be some other component either not seated properly or damaged, even the CPU itself damages. Be careful in handling the components though, you may have just done ESD damage to begin with which makes it that much harder to determine the problem.

One time it made of series of continuous beeps, I turned it off and reseated the memory and it stopped.

Sounds like damaged memory

This is for definite a memory issue. I had this happen on a PC I was doing work on and as soon as I put the ram that was all different frequencies in the right order, the mobo was happy.

Always check the QVL (Qualified Vendor List) of memory that has been tested on the motherboard. Most people think "oh i need OCZ ram to be l33t", but for example my motherboard has known issues with OCZ ram. Checked my QVL and bought a good brand and model of ram that was known good for my motherboard.

If you have a spare power supply laying around, you might to try that and make sure you boot the computer with a single ram of stick and run a memory test. If the memory passes on the test, give the other memory module a shot as well.

If there are no errors in the ram modules, than it would be the power supply. Also you should check, to see If there are known compatibility issues between your motherboard and the memory modules.

If there are, you should consider updating the bios or simply buying new ram modules.

Also, some boards need the memory banked in pairs, and if they arent all the same frequency or brand/model, that can sometimes cause issue too. Usually you put the slower ones(in pairs) in the first required banks, then the rest in the remaining, and they will automatically down clock themselves to the slower memory. If everything is the same, then I'd say choose another brand, and start over. If problem persists, might be mobo, but I think is probably bad or damaged memory.
