've had my SN85G4V3 for just over a week now and all has been working flawless until this evening, went to start up from a cold boot ( system been off for about 10 hours) and everthing powered up, ICE fan was at full speed all led lights came on ( no video signal ) system would just run with fans at full speed and led lights on. I would then shut the system off ( hard reboot ) and then the system would boot up as normal. I did the procedure a few times and with same results. I thought maybe my EVGA 6800GT may be takeing a dump. I don't over clock or have any heat issues, I was thinking maybe a ram problem ( no beeps on start up )If it was a power supply problem I would think the sytem would just die.

any advice?

SN85G4V3 - current bios ( only see one bios @ shuttle )

eye up the resistor caps in there and make sure nothing popped for one.
The PC's where I work do this quite often and the mainboard is usually to blame.
I kinda doubt resistor caps would be bad though/

Try swapping outthe video yet? Might be my first try on this. Start booting with only
1 stick of memory and see where that gets you as well. I am interested in what
may be happening because I just ordered the same model and have not yet assembled it.

Do what you can to eliminate and isolate the problem. Set your Bios to defaults as well just to be safe.
 
Yes, if you have two memory modules, remove one and try your power up/down procedure to see if this goe's away. Shuttle makes an awesome little product, but their mainboards tend to be a bit finicky with regards to memory. I built a v3 this last Thursday for a client that I had the opposite problem in where pressing the power button wouldn't turn off the system. At first I thought the power panel was to blame so I removed it and tried to "hard jumper" where the power switch makes contact and it still would not power off. Turns out replacing the memory of all things was the culprit. I replaced the memory and it powered off/on without issue. Oh, the other issue was plugging in the power cord immediatly powered the unit on, hence why I was trying to get the power off button to work in the first place. :)

If the Video card was the culprit, you can visually check this by the LED that is next to the AGP slot. If it is red, then you have a problem. Green and you are ok (assuming you have a v3 but labeled v2.5 on the motherboard).

Hey -- I'm having a similar issue. I posted on SFFTECH.com w/ Frosty as well. Go figure.

I did the following tonight to troubleshoot the reboot problem I'm having with a brand new SN85G4V3. Basically, a BIOS change will reboot fine. However, restarting from within Windows isn't working. It just does not post or reset. Just sits there with the power button lit up and the fans running.

So, tonight, I tried the following:

  1. Tested 1 stick of Kingston ValueRAM PC3200 DDR in inner memory slot -- NO REBOOT
  2. Tested 1 stick (a different one) of Kingston ValueRAM PC3200 DDR in outer memory slot -- NO REBOOT
  3. Tested 1 stick of Crucial PC3200 DDR in inner memory slot -- NO REBOOT
  4. Tested 1 stick of Crucial PC3200 DDR in outer memory slot -- NO REBOOT
  5. Tested 2 sticks of Crucial PC3200 DDR -- NO REBOOT
  6. Unplugged card reader -- NO REBOOT
  7. Plugged in SATA power connector to Maxtor hard drive rather than 4-pin molex -- NO REBOOT
  8. Reseated PSU cables to the motherboard and ATI Radeon 9500 Pro 128MB -- NO REBOOT

The machine otherwise runs fine. Should I try a Radeon 9800 Pro 256MB? If power is an issue, I would think that a higher power requirement video card would not help the situation. The AGP warning light next to the AGP slot is NOT on, by the way.

Any ideas? Time to RMA to Newegg.com?

Thanks,

Just tried the Radeon 9800 Pro 256MB card I had lying around. No joy.

Suggestions? Time to RMA to Newegg.com?

Well came home from work after a 12 hour day, went to power up the computer and she booted up the first time no problem, 2 days now with all system's go. I think that lowering my volts on my memory from 2.8 to auto my have corrected things, I do hope so.

Click to expand...

So -- were you running the voltage on your memory higher than stock? I'm having the same problem you are with a stock setup. No changes to any memory settings at all from auto.

UPDATE -- I reset the CMOS tonight. No reboot from Windows. I then plugged in a fully functional Antec True Power 480W PSU into the SN85G4V3. STILL no reboot from Windows. My only other option is to reseat the CPU, but would that help, given that it's otherwise working perfectly?

Time to RMA it to Newegg.com.

I just built an SN85G4v3 two nights ago. Had a heck of a time! This thing is way picky about RAM. Top flight Kingston that worked in my SN45Gv2 is a "no-go" here. It will boot, but any attempts to change any memory settings requires a CMOS clear. And ANY changes to the voltage section of the BIOS requires a CMOS clear. (I resolved the memory "issue" by using some Corsair. But since it's a pair of 512MB modules I'm forced to run 2T timings or "NO boot".)

The sad part is: I don't want to overclock!, I just want to run the RAM at the specified voltage. For some reason Shuttle "no comprende". I called Shuttle and spoke with someone who was supposed to be a Technician. What a complete waste of my time!! Every time I mentioned voltage adjustments he kept saying that "Shuttle does not support Overclocking". I didn't get rude but WTF over!?! :mad: I know that the memory controller is now built on to the CPU. And that is what is limiting my performance there. But they have No Excuse for the voltage settings issue.

At this point my confidence in the "Quality" of Shuttle's design and setup has tanked. I'm afraid they're just pushing new SFF designs out the door so fast they don't have time to setup a decent BIOS! So buyer Beware! If I had stock in Shuttle I would sell it ASAP. I'm real tempted to "return" this unit and eat the restocking fee.
