Possible issues with Gigabyte GA-P55A-UD3

[gdavisiv]

So I built a computer for a co-worker last night and it started up with no issues but after about an hr I ran into problems when I had to turn it off.  
when it loads it stays on and run with no issue.. but whenever I start the computer it will get to the Win7 Loading screen and
just turn off.. and it takes about a couple tries to get the computer to load Win 7 but once it does.. it runs beautifully with no issues???

Any suggestions?? Parts list below

Usually it points to a RAM problem so that would be my first check. Try the modules one at a time and see how you progress. If you want to be more certian you could run Memtest86 on them. Post back if you still get nowhere.

Thanks!!

You mind if I ask what makes you think it might be a RAM issue?? how did you come to that conclusion?? just past experience?? or did you come to that conclusion by process of elimination?? *just trying to learn *

Thanks Again so much for this!! I was racking my brain all last night!! I thought it was a PSU problem.

ok so.. one of the memory modules.. the computer will not boot up at all....

if i use the second one.. the computer will boot into windows (and did so 5 times in a row. of booting, shutdown, boot, shutdown)
but now with what I thought was a single working stick of ram.. the computer will boot into windows and then give me a blue screen error.. with this message...

STOP 0x00000051

So interesting note


I was able to run the Memtest on only one of the sticks of RAM.. and it passed the test.. BUT.. when i put the second stick of ram in.. the Memtest % complete would ge to 3% and then the computer would restart.. so is it safe to assume that.. 1 module of RAM is bad??

and if thats the case.. then what the heck is causing me the blue screen error message???

To answer your question after sorting computers for so many years you just kind of know(usually) what the problem will be upon hearing the symptoms. Also your PSU is one of the best, in my opinion and unlikely to be faulty. Just for your future knowledge there is a test you can do to check it. Unplug from the mains and then you disconnect everything from the PSU except maybe one fan for a load. Then on the 24 pin cable that normally plugs into the motherboard you will find one GREEN wire and several BLACK wires. By using a bit opf wire, paperclip or similar, short out the two sockets. Now plug back into the mains and turn on. Now if everything is working as it should both the PSU and load fans should start. If not your PSU is duff(or you forgot to turn on the switch on the pSU)

Yes RMA the ram, it's obviously faulty. By the way you only posted a part of the BSOD message there would have been more to tell you what the problem was. It would have said that the computer was trying to write to an invalid part of the memory or similar(in code of course they wouldn't want to make it too easy)

Awesome!! I will have to remember that.. and try it out.. with a spare PSU i have..

And the error code said Registry Error at the top of the screen and then the code started with


Registry_Error

STOP: 0x00000051 (0000000000000001, 0xFFFFF8A000023380, 0x0000000000c12000, 0x0000000000000374)


Did the registry get corrupted from all the restarts when the bad memory was installed???


And thank you soo very much!!! I'm going to have my friend RMA the RAM ASAP!!!

Yes it's quite possible Windows  might have incurred some damage to the registry or other loaded files but nothing that can't be sorted failry easilly.
I have found you a link to the proceedure for the PSU test: http://forum.overclock3d.net/showthread.php?435-Guide-Jump-Starting-a-PSU

[gdavisiv]

Awesome!! the link has been saved!! thanks so much!! I think I will just save myself the trouble and do a fresh install of Win7 64bit.. once we receive the new RAM!!

Any other tips or tricks??

Thanks Again soo much for this!! You were extremely helpful!!!

[Dark Mantis]

No problem my pleasure. There is no use in having knowledge if you are unwilling to share it. Windows 7 64 bit is so much better than any of the other previous versions and I can't understand anyone not using it in favour of the 32 bit version.

I have just found the video I wanted to post for you to look at. It is on Corsairs website and they do a lot of different how to videos there. You should find them interesting.

**Update its been about 2 weeks as i waited for my friend to RMA the RAM***


So same issue all over again.. the computer loaded for the first time with no issues into win 7... I shut it down and turned it back on
to make sure it would turn off and on with no issue.. and low and behold the same issue all over again.. the computer gave me the same
blue screen error code.. and would not startup windows...

I have not tested the RAM yet.. but I am testing the hard drives with SPINRITE... and the issue is that my friend is running out of time to RMA
the products?? should i test the RAM to see if I have faulty RAM again?? should i RMA the motherboard??

Help me please!! I've never had this many issues assembling a computer!!!

Thank you for your help!!!
