PC Won't Boot or Restart From Sleep Mode - FANs REMAIN ON, PC UNRESPONSIVE

[mentos]

Hello All,

I'm experiencing a weird problem that happened 2x in the last month. When my pc goes to sleep at night, it appears to be stuck in a weird state the following morning. The fans will be on and the PC will not turn on at all. The power button is unresponsive to shut down the PC completely. I need to pull the power plug, clear cmos with a jumper, reboot into bios and redo all the settings. If I don't clear cmos, after i plug in the power and press the power button, the pc turns on for 2 seconds, the fan spin then turn off and continues this way in an infinite loop.

After the first time I figured it was a fluke, a random occurrence. However, the 2nd time yesterday this happened I noticed in bios moving the cursor around, it pauses for 4-5 seconds and is unresponsive. After 4-5 seconds, I'm able to move the cursor and I'm able to affect changes in the bios fields.

Has anyone ever experienced something similar?

I haven't made any changes to my system other than install the deepcool captain 240 AIO cooler last month. I'm pretty sure it's installed correctly too because idle temp is 28-32 and load temps are around 52-54c.

prime 95 yields cpu temps of 61-65c max after 30min so i don't think it can be the cooler.

Any ideas welcomed!

Yah I dont know, our specs are similar and I had the same issue. What kind of drive do you have for your main OS drive and is it getting full or really old? I just turned 'hibrenation' and 'hybrid sleep' off, though if i had to guess... maybe a caching issue? You can check your advanced power settings and try turning them to maximum performance to see if that clears it up. Or try disabling hibernation or hybrid sleep to see if that makes a difference. None of the above helped me but this was helpful to know:

Taken from Microsoft:

Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer into the sleep state is like pausing a DVD player—the computer immediately stops what it’s doing and is ready to start again when you want to resume working.

Hibernation is a power-saving state designed primarily for laptops. While sleep puts your work and settings in memory and draws a small amount of power, hibernation puts your open documents and programs on your hard disk, and then turns off your computer. Of all the power-saving states in Windows, hibernation uses the least amount of power. On a laptop, use hibernation when you know that you won't use your laptop for an extended period and won't have an opportunity to charge the battery during that time.

Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hibernate—it puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers.

Typing powercfg -a in a command prompt will tell you stuff.

While sleep isn't aren't too uncommon, having to reset the BIOS is. This leads me to believe there may be some stability issue at work here, suck as would occur when overclocking.

First thing I would try - set your memory timings to SPD and set the CPU (and GPUs) to default speed. Does the issue still occur?

the issue has yet to occur again after my initial post and with normal, no OC settings.

could this be a sign my board is dying or another component like the cpu is about to kick the bucket?

A computer not running an overclock is not a sing that anything is failing. They call it the Silicon Lottery for a reason.
