Need help troubleshooting hardware problem.

[455olds]

I built a computer a little over a year ago. It had a bad power supply at first but has been running good and stable for the last year after replacing the power supply.

The problem it just started having is random shutdowns ,freezing and screen tearing(also blue lines at bios screen)
It will not make it through the windows 7 performance test without crashing.
I also get a " DQS training failed on previous boot" error message.

For troubleshooting I have tried swapping the two sticks of ram,booting with 1 stick and same problem with both sticks.

I tried clearing cmos, replacing battery and updating bios.

Any advice on what my next step should be? Sound like a bad motherboard or bad cpu?

Here are the specs

Any help appreciated. I am at a dead end with this.

Try a different PSU and Video card. See if that resolves the problem. Perhaps pull one out of an old system if you have any laying aorund...

 

[DarkTower]

Also try lowering the speed of your RAM.

Here is a picture of the screen tearing.

Might be a bad motherboard if you're using the onboard video.

 

[455olds]

It is onboard video. Maybe I should contact Biostar and see if I can rma the board? I really don't have another power supply or video card to try in it. I don't want to take apart my main rig.

i have a gigabyte 785g in my fs thread. not ddr3 but if you have some ddr2 it would work for you. let me know if you want to buy it. its micro atx too

ialso have lots of ati cards for sale. you could always try a pci-e card instead of onboard and see if that helps

 

[455olds]

I sent motherboard off for rma. Biostar has been really good about it so far,they got back to me quick.

Will I be able to tell if I got the same board back? Will it have a differant serial number?

 

[455olds]

They sent me a replacement board with different serial numbers. The new board is in and works good. Thanks for help,esp Danny

 

[Dangman]

No prob. Hopefully that solved the issue you're having.
