So, I'm trying to stretch the legs of my A64 system, and I bought another 1GB of RAM to bring me to 2GB. The system is the one in my sig (though I have been running it at stock speed for several months). The machine has been working without problems.
I pop open the case, pop the sticks of RAM in (filling the bays) and start up....
And it hangs at POST, before the RAM is recognized. I reboot, and it sees the 2GB of RAM, but stops. Another reboot, check the BIOS, and it gets to the Windows screen...but no further. I tried again, and again at the Windows screen. So I reopen the case, remove the new RAM and boot....and it goes straight to Windows. So, I shut down again, put the RAM back in, and I get the same problem as the first time (no past post). So I remove one of the sticks, and try it in each slot...the first time, it didn't even see it, and the second time, it registered as 512MB, not even seeing the original RAM. So I take that stick out, and substitute the next stick....and I get beeping, so I pull it out, and try to boot with just the original RAM...and.....
Nothing. Fans don't spin up, just pure silence. So I check the power cord, check the PSU switch (even trying both)....try shutting off the PSU for several minutes, then try leaving it on for several minutes....nothing. I check the switch connection to the motherboard...no problems there. I check every connection in the computer...all secure. I check the power cord, the UPS, everything. I even check to see if the voltage switch somehow got switched. And....still absolutely nothing. Dead silence.
What the heck? I've built three systems, done countless upgrades, and I've never experienced that. What the heck happened, and what can I do about it?
