1218086 2011-07-21 05:54:00 My friends building a new computer, i'll list the specs then say the problems and what we've tried .

Motherboard - MSI 990-fxa gd80 ( . msi . com/product/mb/990FXA-GD80 . html" target="_blank">www . msi . com)
Video Card - MSI R5870 Lightning Series ( . guru3d . com/article/msi-r5870-lightning-review/" target="_blank">www . guru3d . com)
CPU - AMD Phenom II x6 1090t ( . anandtech . com/show/3674" target="_blank">www . anandtech . com)
RAM - Gskill 2x2g 1600MHZ
PSU - Corsair TX750watt .

Basically with it all installed, he turns it on, and his motherboard shows Error 54, on the LED Debugg panel, he cant find any info except it was apparently a RAM issue . So we tried working RAM from my Computer and He bought an El Cheapo and tried it . Still the same .

The Monitor displays nothing no matter what . It is a working monitor . Hard disks turn on, and this computer has never been turned on before . He has the right video card cord, and connected .

He's replaced his Motherboard, and a bigger power supply .

tl;dr, New computer, won't display anything on screen, LED Debug panel shows error 54 .

What is error 54?

Thanks in advance . :help:cool:

1218088 2011-07-21 06:08:00 If the LED is part of it the manual should tell you what the error means

One reason it wont turn on: The BIOS on it, doesnt support the CPU

1218089 2011-07-21 06:33:00 Do you have a spare video card? Try with another video card and see if that works. I recently built a PC and found out the new video card was faulty. The PC would not start with the new card, but worked fine with my older card. Got a replacement for the new card and that worked fine. ronyville (10611)
1218090 2011-07-21 12:21:00 The manual doesn't show codes that match, just the ones that should come up during start up and it does say the CPU is supported here (pt.msi.com) (fourth from the bottom)
I don't have a spare video card at the moment, but I could use one from my mates once he gets his back from repairs.

1218091 2011-07-21 19:01:00 I know the CPU is listed, but is the BIOS version (it needs on the system now)?? It has to be, (before the CPU is installed) to support it. The system wont turn on (if 11.0 of the BIOS) isnt on it now. I would send them an email. And ask what that error means Speedy Gonzales (78)
1218092 2011-07-21 23:51:00 seems like error 54 is memory not seated correctly, but that's a dubious google result from a forum somewhere so I'm not certain about it.

You mention a new motherboard, and trying different RAM so it seems like either the CPU is faulty or unsupported as already mentioned, or you guys are making a fundamental mistake somewhere.
Go over all your connections, make sure both power connectors are connected correctly to the motherboard and all headers/ jumpers are correct.
Disconnect all drives and try booting with just MB / CPU / RAM
Make sure the Memory is seated correctly, installed the right way around, and check whether the motherboard requires it in specific slot configurations - some boards require pairs in the correct slots to work.
