So I'm new here and I know someone asked a similar question but my situation is slightly different. I have been using my friends custom computer for the past couple of months because he doesn't use it at school. So randomly the video output would just freeze and I would have to manually restart the computer and if it did start I would get this message "DQS training failed on previous boot, Revert to slower DRAM speed Press F1 to resume." then the computer would work a little while but then eventually do this again. Sometimes the computer will not start for days. When I do try to start it, the tower turns on completly and I get no beeps but the monitor receives no signal, just remains black. The parts for the computer are as follows

Motherboard - http://www.newegg.co...N82E16813138143

Processor- http://www.newegg.co...N82E16819103471

Fan- http://www.newegg.co...N82E16817153052

Ram- http://www.newegg.co...N82E16820146785

Hard drive - http://www.newegg.co...N82E16822136283

I'm just really not sure what is stopping it from starting or how to start it. Any help would be great, thank you.

Hi and welcome, sorry for the delay.

I have seen similar issues before, there are a few things to try:

1) When the computer starts, enter BIOS setup, choose to apply fail-safe defaults, hit F10 to save and exit. Continue using computer and test.

2) Check the motherboard support page for a BIOS update. If available, update, then continue using computer and test.

3) Replace the motherboard.

Regards,

Troy

Thank you very much, just a couple more questions, to make sure I'm understanding everything.

Seeing as how I can not even get a response from the monitor I'm not sure if option would do. For the second option, the support page is online correct? I have a feeling that the reason is that the motherboard is just spent, but is there any other way besides the obvious fact that the computer will not work, to check if the motherboard is actually broken?

Ah, I got the impression you could use it sometimes and not others. So now it doesn't boot at all? Do you hear any beeps?

The best way to check is to replace it and see if everything then works fine.

At first I could use it sometimes and not others, but recently it won't work at all. I also get no beeps so I was thinking the same thing as you, replacing/upgrading the motherboard.

Yeah these ones can get a bit tricky, the best way to diagnose is start replacing parts and test after each replacement until the culprit is found - although be careful, often you can find "culprits" - more than one part! I love those ones :)
