PC wont return from sleep mode

If I put my PC to sleep and try to wake it up, it freezes instantly. It didn't do this until I upgraded to Windows 8. Any ideas would be appreciated because I am clueless.

 

That's odd. Your system freezes instantly after waking up from sleep? Or is it a different phenomena we're talking about?

 

I got this issue for a few months, a bios update fixed it; something in my chipset went wonky when I was installing drivers I guess. Be careful if you're going to flash your bios though, I'd suggest exhausting ALL over possibilities before resorting to that. As if you mess up it can cause a LOT more serious problems.

 

Most likely this issue is with one of the ACPI drivers. Have you attempted to update your video drivers? Typically video is one of the most taxing things to recover from after any kind of standby, also are you receiving any BSOD's?

 

I can't offer any suggestions, but I thought I'd share what happened to me. Just bought a brand new HP desktop with 8.1 pre-installed. Ten days after I got it, I left it unattended for about an hour. Upon return, it would not come out of sleep mode at all. HP helped us reload Windows and start all over. He said it was a flaw in 8.1, which Microsoft was aware of. He said not to leave the computer unattended for longer than 30 mins. Just to see what Microsoft would say, I told them what HP had told me and asked when they would fix it. Their answer? It's not Microsoft's fault (surprise surprise). It is a corrupted system file and for $149 they will fix it for me! Okay. So who do you believe? I've never trusted Microsoft, so I'm going with HP, but that still doesn't solve my problem!
