T3610 Blinking Orange Power Button

Question

I've been recently having problems with my T3610 where it will randomly turn off and the power button will flash orange. I leave this workstation on all the time so I can't say what might be happening prior to the crash, but there are no errors in Windows event viewer.

Sometimes, I can just unplug it, wait a minute and plug it back in and it will come back on. More recently, I've had to remove the RAM and Processor to get it to come back to life. I originally suspected the power supply, but after the most recent crash, it no longer registers the memory in DIMM8 and DIMM4 (i.e., in the BIOS, it acknowledges the DIMM is present and it sets the memory to 4-channel, but it detects 0MB rather than 8MB), so now I'm wondering if the motherboard is dying.

Does anyone have any ideas on how I might isolate the problem?

Yes. Plus we know it definitely isn't a Windows problem as it rebooted during diagnostics. I've also been thru PSU problems myself. When they get into that random reboot habit, they eventually die.

I remember you once suspected the RAM. If it were bad, the PC wouldn't boot at all. I think it fell into the category of not enough power from PSU on all the rails. Also: PSU Testers on Amazon

Random shutoffs and blinking amber power light are both telltale signs of a failing PSU. A failing PSU may not be providing full power on all of the rails even if the machine does run.

With the T3610 being 5-6 years old one can try replacing the size 2032 CMOS battery. I say that because you had other behavior patterns with it. But just so you know, it won't fix a failing PSU.

Thanks for this. I came in this morning to the blinking orange power light. Once I got it back up and running, I ran the onboard diagnostics. The first time I ran it, the computer rebooted during the memory check. The second and third time I ran it, it rebooted during the fan checks. Just now, I left it on the 'No hard drive found' screen and it rebooted after 10 or so minutes.

This is most likely a PSU problem, yes?
