I have a T6212 tower. In an attempt to switch the fans and other hardware from a newer emachines to this old T6212 which has never given me problems and runs smoothly up to this date, the system will now not load.

I removed the fan along with the cooling CPU system in order to clean it and replace the fan. I also removed all ATA cables along with the power supply unit. The computer turned on fine but nothing would come out on the screen. Since it didn't load, I switched the new hardware back with the old (original) hardware.

After turning it on with all the original hardware back into it, the system would still not load. The computer turns on and the fans work fine but the monitor's light stays in yellow and the system just does not load, even with the original ATA cables and original power supply unit.

I honestly do not know if switching them has anything to do with it or I am thinking it has to do with the pins or "master vs slave" but all seems to be connected properly but then, I am no expert.

Can anyone help me out with this??

Re-check all connections...remove and reseat the RAM.

If using onboard graphics...try a physical video card, rather than the onboard graphics.

Thanks Louis.

I re-set all ram card (I have 4) and connections have been rechecked over and over. I also removed this wintv video card I had on a PCI slot but that made no difference.

I don't know what else it could be, this is frustrating.

Give the mobo connector a good push down, sometimes they "click", but only one side actually connects, I've had this happen.

If that fails, unplug all the power leads except the mobo and any gfx card and try again; another fault I had that stopped a system booting was a drive going short circuit and taking down the 12v line.

Finally, it could be the gfx card (if fitted), I had a perfectly good X1950 that died when I moved the mobo to a new case, same mobo, same psu, but when starting the new case..... dead.

Ok, something interesting just happened.

I removed 2 1gb ram cards from 2 of the slots (leaveing me with a total of 1gbram) and now the system loaded.

Why would this happen? How can I make the system load with the 2 1gb ram cards back into the slots?

Apparently, I solved the problem.

Thanks to everyone. Will make another thread about reading a hard drive.

Have all four modules been installed always?

Did you add RAM recently?

Not recently but it turned out to be the RAM. I replaced them and it loaded. I had to replace them 3 times in order for it to load.

Thanks for your help!
