Ram not working

[jorda13456]

Ok so yesterday my pc automatically shut off and that was it for the powersupply I guess it died...

Anyhow I put in a new power supply replugged everything and now my ram is causing so much issues that never happened before.

Ram Type : OCZ

I have 4 x 1GB OCZ ram.
When I plug into slot 1 ,2 , 4 computer boots BUT ONLY DISPLAYS 1GB Ram Installed.

When I plug the third ram into third nothing appears on the moniter when i try to turn it on.

What is the cause for this maddness , I'm really irritated.

Troubleshoots I've tried:
Booting each ram individually ( ALL 4 WORK ).
RESETTING CMOS / BIOS
Unplugging hard drives
Unplugging Graphic cards
Using VGA Cord To Onboard VGA / HDMI
retrying old power supply ( still dead )
Plugging in 2 ram cards at a time ( STILL SHOWS 1GB 🙁 )
Plugging external usbs / etc out
Resetting computer
Tried Memory Type : Unganged - Ganged

Can someone give me a working answer, I don't know what to do.

Please fast answer Thanks\\

`Im on the computer right now only showing 1 GB Ram Installed

Best guess is that when your PSU went down your MOBO took a hit too. Try the RAM in a different board if you can, I'm betting it works fine.

All my Ram cards work but slot 3 does not work, so I guess it's corrupted....

"When I plug into slot 1 ,2 , 4 computer boots BUT ONLY DISPLAYS 1GB Ram Installed" Only 1 showing means RAM and/or MOBO was damaged when the PSU went. have you individually tried each slot with a single stick. Also look for burn marks where the contacts in and out of the slot are. Since your RAM sticks work individually it seems likley that the MOBO RAM slots are damaged. In which case I'm afraid the only solution I can suggest is new MOBO.
