I'm not suggesting win 7 for a permanent fix, just ways to try and isolate the problem as we don't know if the problem is with the card itself, the motherboard or some other system component or just a win 8 driver issue.

These are the tests I would do

1. Try another PCI-E slot on your motherboard. If this fixes it, then its most likely a motherboard problem
2. Try a different monitor, if the problem goes away, its something to do with the handshaking (EDID info, capabilities, etc) between the computer and TV/monitor
3. Try different interfaces (VGA, DP etc) to the monitor, if this fixes its either monitor or GPU related
4. Try your 4850 under win 8 - if this works then it could well be something dodgy with the 7970 but if it exhibits the same problem then it could be a win 8 driver issue or motherboard issue
5. Try your 7970 under win 7 - if it works fine win 7 then it's most likely a win 8 driver issue and unless you or someone else reports it to ATI/Sapphire/Microsoft then it's unlikely to be fixed anytime soon
6. Try your 4850 under win 7, if it exhibits the same problem then it is highly likely that it is your motherboard or other system component (monitor maybe) that is causing problems.

At least if you do those tests, you'll know where to focus your efforts and then you can contact the relevant manufacturer for help and/or forum people here. I don't think it's likely to be a trivial fix so the more information you can gather the more likely someone will be able to help you solve it.

If you want to do the minimal amount of diagnosis then simply RMA the card and get another one but it will take you a lot longer than these tests you can do in a few hours. Its a shame you don't have a old spare hard drive lying around as it would make testing a whole lot easier.
I suggested a HDTV only because it was another display to try. The stretched and blurry is likely due to overscan, should be quite easy to change in CCC under the TV display options. Set the display to 1280x720 (standard 720p resolution) as your TV will support that and if it has options for overscan, disable them on the tv.

It would certainly be worth trying with a real monitor if you can borrow one. TV features like auto switching inputs could be causing some of the problems.

That's pretty much all I can think of for now


Okay I'll try those out when I can find the time. Maybe tomorrow as I'm caught up with other stuffs right now.

And thanks a lot for the help so far! I'll try out your suggestions and get back to you! smile.gif

Alright, so here's a screen shot of the most recent crash. Can anyone make out anything from these logs?

Over 40 posts and no one told you it is a driver/MB bug, aka sleep bug?

A sleep bug? Care to elaborate? And is there a fix?

There's not really a fix other than trying different drivers. The problem with the beta drivers is sometimes certain fixes get skipped from on version to another. Also, the way specific motherboards work in S1/S3 affects the sleep bug too. You can test it by just using DVI and sleep should work like normal. But other ports like hdmi/dp have synch issues and are affected by the sleep bug.

I see. But is my issue the "sleep bug"? Because my PC doesn't only freeze/hang when I put it to sleep. Even when it's idle and the display turns off. After about 45minutes~ or more it fails to wake every 1 in 3 times and the only way to fix it is a forced restart.

When you say beta drivers, do you mean ATI drivers? Or motherboard drivers? I am already on DVI though..

Also, could you explain to me a little about the S1/S3 sleep states? I've read about it but I don't really understand what it means or does. And how can I change it? I can't find anything about it in my BIOS.

Hmm, sleep bug and idle lockups are tow separate things. Sleep bug is a gpu/driver/mb compatibility issue and idle lockups are cpu overclock settings afaik.

When you say the display turns off, did you mean the monitor turns off or the rig goes to sleep. They're two different things. If it's just you monitor shutting off and the system is still idle, then that's probably more to do with your rig.

It's hard to tell if you have the sandybridge offset idle lockups or not since you didn't fill out your rig specs.

Ah I see.. But hmm, the confusing part is, all of the above happens to me. My PC can freeze up from idle while on desktop, idle in lock screen or simple failing to wake from sleep.

And when I say the display turns off, I meant the Windows feature under Power Options to "Turn display off after.. XX minutes". I set it to turn off after 10 minutes.

How do I fill in my rig specs? Lol. But I have a 3570K which is Ivy Bridge. But anyway I've put in my specs on the first post but I'll paste it here again for convenience sake.


Specs:

i5 3570K (OC @ 4.5GHz 1.32V)
ASUS Z77-V
Sapphire 7970 OC 3GB
Intel 520 120GB
WD Caviar Black 1TB
Seasonic X 850W
Samsung SyncMaster 2032MW (1650x1050 Screen)
Windows 8 Pro x64
