PC won't shut down, won't wake from sleep - I'm stumped!

[madmad]

Hi folks,

My old q6600 workhorse started crashing of late so I decided to finally lay it to rest and use an i5 HP Pro tower I had lying around. Bought a new Evga PSU, more ram and moved the gfx card and SSD from the old machine to the HP. Installed win7 - all is well except the damned thing won't shutdown completely, it appears off but the fans keep spinning and I can't turn it on again, I have to flick the psu switch. Same with sleep mode, fans keep spinning - won't wake up. The only thing that works is "restart" but even that takes longer than normal. Any ideas why that may be and what to do to fix it?

It worked fine prior to me swapping the parts around so I've tried putting it's old psu and ram back, install windows again - still no joy. Looked through bios for any power related options, none are there :/ Reset bios to defaults - nothing changes. Any ideas are much appreciated...

MaD

I had a 1 TB Seagate hard drive that did this. As soon as I moved the drive to other duties, the computer shut down normally. I doubt this is your issue, #1 since you don't have a hard drive. But go ahead and check device manager for any issues.

These can be hard to pin down. Could be a part that needs another driver. One thing I didn't do, but probably should have, it to look in device manager for drivers that aren't responding.

Another factor, which I didn't quite get from your post, is how far it gets on shutdown. Is the screen blank, or does Windows still say shutting down?

So to recap, tell us what is on the screens, anything around shutdown time in the event log, and anything in Device Manager that is showing question or exclamation marks.

Since you've swapped old parts back except for the SSD and it hasn't improved, I would suspect the SSD being the problem. Double check your BIOS settings with regards to SATA mode. If it defaults to IDE (Legacy) mode that may be your problem. There may even be an incompatibility between the SATA controller and SSDs.

Thanks for the input guys, luckily clearing CMOS solved the problem, it works like a charm now

Nice. Since the reset didn't work, I wonder if it needed to make an adjustment, that it didn't didn't provide an option for when the the new hardware was added.

Hey ketchup!

I was actually able to replicate the issue. It occurs(at least in my case) when you press the power button with the 4pin cpu cable unplugged. After the cmos fix I had to unplug it to be able to put the storage hdd in and forgot to plug it back in. Lo and behold - no wake from sleep or shutdown were back again. Interesting how what I'd think of as a fairly innocent error could have such an effect.

That is interesting, as most computers over the last five or so years won't even boot with this cable disconnected.

I think I didn't word it properly - it did not actually boot but upon pressing power button mobo must still be getting some current for a split second as the fans do a "little spin" and perhaps that's when the settings get messed up. At least that's my guess
