Recently my computer hasn't been waking up from sleep mode. It's gone from happening once a week (putting the computer to sleep several times a day), to nearly every day and from yesterday it won't wake from sleep mode at all, I need to turn it off and on manually if I try to use sleep mode.

What I used to do: Click Start ->Sleep.
When waking: Press spacebar. Then the computer would wake and work just fine.

Now: Start -> Sleep.
Waking: Spacebar -> Computer lights turn on then computer dies and restarts itself ->Restart does nothing -> Press power button to turn computer off -> Power button on -> Windows restore starts -> Computer freezes -> Power button off -> Turn on once more and the computer will start again.

Recently I went from a HD4850 graphics card to a HD7750 (that uses less power) and the problem started happening more frequently. The new graphics card was installed 3 months ago. That's the only change to my system since I got it a few years ago.

I think it could be the power supply (or a driver issue with the 7750, but if that was the case why would the problem become more frequent over time?) but I'd like to get the opinions of more computer savvy people than myself.

System:
Processor: i7 920 OCed to 2.8GHz (Stock 2.66GHz)
MB: Gigabyte X58A-UD3R
RAM: 3x2GB Kingston
Graphics Card: Gigabyte HD7750 2GB DDR3
PSU 850W (I think)

Hopefully someone here knows what the issue is.
 
Remove the the power plug from the power and hold the power button for 30seconds, reconnect to power and try again.
 
I had this happen to me almost exactly for a month or so a couple years ago, and I tracked down the problem to be faulty soundcard drivers that were crashing on restore; but in my case it just started doing it one day after working fine beforehand.

I tried this, no luck.

Look through some of those.

I'd check event viewer and see if anything gets posted saying it crashed.

Have you updated your Gfx card to latest drivers from website, or did you use the disc or windows update? I'd grab latest drivers from amd. Since that's the only thing that has changed I'd start there.

I have the latest drivers so it isn't that. And I've been looking through those links but they all seem to have different solutions (some are hardware related some software related).
The event viewer doesn't show me anything odd even straight after a crash.

I'm also looking at the updates that I've received recently. Unfortunately none have a known error where the computer won't restart.

I'll probably try a system restore next. Edit: I just tried 2 different restore point and neither of them would work. So I think that plan's down the drain.

Seems unlikely but there's a possibility it's your power supply, I have no idea how you'd test it though.
 
If you've had the computer for more than a year, it may be beneficial to do a clean OS install and hope it fixes your problem. It is really hard to say what's going on but I lean towards software not hardware being the issue here.

Good luck.
 
Does it happen every time?

If so do you have a computer shop nearby, like a mom'n'pop store that would let you try a different power supply. Even if they are a repair shop they will have a known good power supply to test with. You can probably take your tower in and try it in the store with them.

What kind of power supply do you have?
 
I really hope it doesn't come to that Pako. I hate having to re-install OS's, it takes so much time and then all my old programs need to be installed too. :(

Infinital-NG, yes now it happens every time I put the computer to sleep, it used to happen randomly though. It would go for days - weeks without a problem then the problem became more and more frequent.

There is a computer shop in town, they actually built my computer. I'll take it down to them next week if I can't figure it out shortly.

I think the PSU is from coolermaster but I don't know the make or model.
 
Have you checked if everything is OK in the BIOS and advanced power settings in the Control Panel→Hardware and sound? I can't think of anything else than these.

Feel free to search or ask about the options if you're not sure about them.
