Hey, need help if anyone can provide it. This is NOT a new build, it has worked fine for years but throughout the month before it died I got occasional blue screens of death and freezes. I didn't take pictures of what it was though and don't know what it said. It happened maybe 4-6 times in the month. It would either freeze or blue screen, then try to automatically restart but it wasn't able to. So I would shut off the power switch, flip back on, then turn on computer and it would work fine after that.
Then one day it went off again, attempted to restart and wouldn't like usual. But after I turned off/on power switch it wouldn't display anything on the monitor and NO beep at all (before it would beep once when you turned it on).
but am still having problems. When I take out all ram and ONLY have the CPU installed then boot, the system posts one short beep, one long beep. hold for about 3 seconds, then one short beep, one long beep, hold for 3 sec, and so on. It keeps repeating like that. When I go to american megatrends section of bios beeps (which is the one I have) there's no option for one short one long. I've looked at other types of bios beeps and the same there's no option for saying what it means. When you boot it doesn't start with long it starts with short.
I have 4 ram sticks, 2 of them are the same the other 2 are different. Each one I've tried in each slot while booting up. All of them end up with silence when you boot, no beeps at all and no display on monitor.
It isn't a new build I haven't touched anything with the CPU plugs so none of that has changed. I've tried to take out the battery for the bios and same thing, I've reset the CMOS and same thing. No beeps with ram, nothing on the monitor.
The CPU fan still spins, but when you plug in keyboard or mouse no power goes to them.
I basically don't know if it's a power supply issue or motherboard issue. I don't have that digital meter thing so I can't check voltage on PSU and I don't have another computer similar to mine to try PSU on. Are there any other tests I can do to try to figure out which is the culprit? If it's just the power supply then I can only replace that but if it's motherboard it will be more of a nightmare since I'll have to try to use knoppix to get data off my HDD. So I'm hoping it's only a PSU issue but I don't know.
My motherboard is Foxconn A7GM-S, CPU is Phenom 2 X4, Power supply is Antec Earthwatts 500W. I have 2gb ram sticks. I have a separate video card too but my mobo has internal video so I've been testing on that. All of them I either got in 2009 or 2010. Would be much appreciated if anyone could let me know what they think, thanks.
