Good day to all
After a long and hard effort, I managed to collect selected older hardware and I built a nice and descent PC, based on the captioned Mobo/CPU/GPU combination in a large full tower Thermaltake Xaser VG4000BWS case, a plethora of storage hard drives and several other peripherals. The case allowed me to add a second PSU, thus the PC was powered by two PSUs, working together, in order to undertake the extended number of the HDDs, installed in it. This project had been implemented about a year ago and it was completed with Windows 8 Pro, 64-bit OS. Till a few days ago the PC was working fine and flawlessly.
Last week, we had a prolonged local electric power black-out. The PC was connected to a Line Interactive 2000 VA/1200W GTEC PC615-2000R UPS. Unfortunately, I was not at home at the moment of black-out and when I returned, I found the UPS almost exhausted and the PC was at a strange continuous start/shut-down status.
I disconnected it from power and I shut-off both PSU switches immediately. I waited long enough until we had a complete power recovery and when the UPS was fully charged again, I connected the PC again to it and I tried to put it on again.
Unfortunately, there was a complete boot failure. The PC starts for 2 or three seconds, I receive a one-or-two-second beep and then a very short beep. Then, the PC shuts down and after two seconds restarts again. I receive no picture at all (not even the BIOS initial screen) and this is it! I repeated the test again, with the PC directly connected to the house power receptacle, in order to exclude any possible malfunction of the UPS, but I had the same results.
Looking further into the Internet, I found a list of the possible beep error codes for ABIT motherboards. In that list, it is mentioned that 1 long and 1 short beep means DRAM error. I tried to replace the existing four DIMMs with two alternative pairs of DIMMs, having previously tested and confirmed that were working OK.
For your guidance, the test was done once with both PSUs connected, as it had been the final configuration of the PC, when it was finished. Then I disconnected the second PSU and I tried to start the PC with only one (the primary) PSU, having disconnected all the extra peripherals that are powered by the secondary PSU. The results were exactly the same.
Can anyone guide me where to look further, in order to identify what the problem is?
Thanks in advance.
