Hey guys, At the end of my tether as usual - am trying desperately to complete a build by a deadine and all of a sudden I've hit an issue where every time I try to shut down Windows, the hard drive and monitor go off, but the GPUs, fans and pump are all still going. There's nothing happening at all with the disk so I know it's not updating in the background or similar. Just that all lights and fans remain on. Only three things of note that I can think of have changed recently since it was last working fine: I've been experimenting with a custom shutdown sound file via the task scheduler, which was suffering some issues but right at this moment actually appears to be working, which is odd in itself since I put it to one side and hadn't tried to make any more progress with it After asking someone to grab something from the workshop room whilst out, I came home to find the machine on but in a deep sleep state (as in, the GPUs and fans were spinning but nothing was happening onscreen and the only thing that would wake the system was pressing the power button). This has happened a few times before and nothing major has come of it, plus I'm confident the other person would not have tuoched the system I offered up a second GPU next to the first to measure length and must have touched the board somehow as there was a kind of zap and a burning smell. This has me stumped (not least because it has never happened before) but although it is both the most worrying and easiest to blame of the three, the system still boots and runs fine. Just won't shutdown. Still no idea what the zap and smell was either! To resolve, I've now tried a few of the things I could find on the internet that actually made any sense (or suggested hope), such as turning off Fastboot, booting to UEFI and shutting down manually etc. but nothing has made any difference. I could really use a hand here chaps, as I'm massively against the clock - if I can deliver the system in a working state then I can at least finalise the config remotely. All assistance massively appreciated - G-Man, if you're listening, you're usually the man with the plan! Thanks in advance, all...
Ah. Appreciate the mega-quick response but I feel a bit of a let-down. I haven't hooked those front panel leads up yet. I'll do it now and also try to reset the UEFI. One at a time, of course. Cheers Red! Edit: shutting down now to find out about power LED
Right - here are my findings (am on AsRock Z77 Extreme 6 for reference): POWER LED IS SOLID Didn't reset UEFI yet as thought should do it one step at a time No shutdown sound (more on this later) Once "shutdown" (disk off, no activiity), fan 1 was off (connected to CPU_FAN2). Radiator fans connected to CPU_FAN1 had both fans running Pump switched on (PWR_FAN1) - was lit but not sure if pumping. This is a Cooler Master Seidon 240 V Whole system otherwise looks off bar fans, as above CHA_FAN2 & 3 both on, although CHA_FAN1 (4-pin) is off - low startup voltage issue? Both GPUs on - MSI 970 has both fans running even though normally doesn't; Galax Infin8 has one running System played logoff sound overlapping login sound when logging back in - clash? Shutdown blocker?
Further info - when in that odd non-shutdown-everything-spinning state, nothing will wake the machine, so I'm guessing it isn't actually sleeping.
Have now also tried the clear CMOS switch and removing the battery for thirty seconds but issue persists...
Righto, thought I'd pop back and close this thread out. After trying most of what the internet advised me to do, I gave up in the end and swapped the board out for an identical one. Seems to have done the trick (touch wood) so I suppose I must have shorted something out when I measured up the extra GPU whilst the board was switched on. That's never happened to me before (heard that line somewhere...) but hey ho, lesson learnt. The old board is still useable, but with the shutdown issue. Not sure about how safe that is though, so might just use it somewhere it can always be switched off properly.
Just seen this, glad swapping it out sorted it. Seems an odd one that it works fine apart from the shutdown issue.
