GA-770T-USB3 Freezing, BSOD, Random restarting

[biggyk]

I forgot that I had a 400w psu from my old Pentium 4 system, do you think this would handle what I have for now to do some testing? Says peak 500w. I have two molex to pce-E connecters. Might be a good idea before I sent the mobo in? What would you guys think?

Hi,

well you have nothing to lose by trying it out and given your circumstances I think I would try it too.

[biggyk]

Do you think it will handle of 460 though? Thats the only thing im worried about.

[Dark Mantis]

Thermatake is a good make and should actually handle more that it's rating especially just for testing purposes.

Just an update that my computer has been running stable since the day I got the cpu back. Dont know why or how but im just glad its fine so far. Thanks for all your help and im sure I wont be a stranger in the future.

Sorry to barge in but i''m having the exact same problem with random BSOD's and reboots. I build alot of systems in the past, so i kinda know what i'm doing but this build is just horrid. It doesn't crash when it's stressed just randomly when idling/browsing or BEFORE the welcome screen and then it works ok for a couple of days again. Things tried:

Memtest runs 2x 12 hours - PASS
Prime95 runs 2x 12 hours - PASS
Reinstalled 4 times (different OS's) - no change
changed hard drive brand - no change
changed memory - no change
changed cooler - no change (was really heavy)
changed videocard - no change
changed USB keyboard and mouse to ps/2 - no change
reseated everything
checked wattage with a watt meter and was well within the norm
updated BIOS twice
all temps are fine and well within the norm
looking on the web for similar problems
asked gigabyte for some pointers

Specifications:

Motherboard: GA-770T-USB3
VGA Brand : GIGABYTE      Model : ATI HD5770
CPU Brand : AMD 1055T (125w)
Operation System : Win 7 64-bit      SP :
Memory Brand : Kingston      Type : DDR3
Memory Size : 4gb      Speed : 1333
Power Supply : Corsair 450 W

It's beginning to look like it's the mobo or a flakey PSU. I'm curious if the original poster's system is still stable since his last report.

[biggyk]

Yeah its stable now, and I dont really know the exact cause. My ram is down to 1333 from 1600. I sent the cpu away and amd said that it was fine and passed all tests. Iv been good for a week now.

It is quite possible that it is simply down to memory settings in the  BIOS. If it was an Intel board I could try and help you but I'm afraid that I am not familair enough with the AMD platform. I am sure that absic or one of the other AMD afficionados will be along to help though.

Hi there,

this kind of issue can be really frustrating and is one I have experienced for myself in the past.

I guess, as you have tried everything else the best option would be checking your PSU is delivering enough power. In the User's Manual for the GA-770T-USB3, Gigabyte actually recommend a PSU of at least 500 Watts and although your 450 Watt my seem adequate this could possibly be the root cause of your problems. If possible try swapping it for another PSU to see if it is as simple as that.

The other thing that springs to mind is have you manually set the RAM Timings and Voltage or have you left them at the System Default settings? I had all kinds of problems when I tried to set my Corsair RAM to their stated ratings and eventually discovered that it was better to leave them set at the system defaults. They should have been able to run at  8,8,8,24 but preferred running at 9,9,9,24.

The memory timings and voltage were on the standard setting during all of this, i'll have look at what kingston's values are and manually enter that. As for the PSU, i don't have a 450+ one to test with. Wouldn't the PSU cut out under load if it's too light with a combined prime95/furmark run to see if that's it.

And that cup of tea and shouting did calm me down a bit, never knew the power of that combo

Not always and that is part of the problem. I built a PC for a friend and he kept bringing it back to me saying it "locked" or "froze" and sometimes it wouldn't get past the Windows Splash Screen at startup. It took me quite a while to realise it was the PSU, even though it was new and a 550 Watt one it was faulty and it would work happily for a while then give the type of symptoms that you are experiencing.

Pleased that the cup of tea and a good swear have made you feel a bit better..... it always works for me!

Bought a Antec 550W power supply today to see if that fixes it. Also i noticed that in a cold room on cold boot the system's buzzer goes on for about a minute and stops around the time the OS is loaded. It also does that with everything unnecessary disconnected and with a different videocard.

That sounds like an issue with the fan alarm where because it is cold the fan doesn't come on immediately and then the motherboard senses that the fan isn't turning fast enough and alarms until it heats up and the fan turns faster.

Same problem with mine since day 1.  I could rarely boot successfully twice in a row.  EVER.  I would just put it to sleep instead of subjecting myself to the hit-and-miss crapshoot of booting this thing up.  

Seemingly random BSOD error messages, it crashes any time between the initial BIOS screen and loading Win7 desktop.

FWIW, earlier this week the on-board LAN died (I checked to ensure it was still enabled in BIOS, updated drivers, swapped ethernet cable, tried all that stuff).  I am unable to uninstall the Realtek network adapter via Device Manager - it just shows the entries with yellow exclamation points.

Once I disabled the on-board LAN in BIOS (and disabled all the LAN devices in Device Manager), my system now ALWAYS boots up without a problem.

Of course, I can't access the internet or game but at least now it boots.   I've probably rebooted a dozen times since Monday and it BOOTS. EVERY. TIME. As I said, prior to this, it has NEVER successfully booted more than twice in a row.

I ordered an Intel PCI-e LAN adapter.  We'll see if the happiness continues . . .

Indeed, disabeling the fan monitor corrected this. Sadly the main problem persists. I've bought another am3 mobo and CPU (sempron) and swapped everthing around so the athlon x6 on the new mobo and the sempron on the gigabyte. Everything runs great. But i was expecting one of the systems to fail. The higher power PSU also did nothing and just hours ago a samsung hd died on the gigabyte board, not sure if it has anything to do with it but i did test the gigabyte board with a different brand hd already to no avail. The system is stable for a few days now it seems but it has streaks for up to a week and then it starts again.
