Reboot troubles

[arcas]

This is a longshot...

Finally assembled my Opty system and I've noticed that the system hangs during POST if I warm boot. According to the DFI diagnostic LEDs, it cannot detect the video card. Cold boots and power-cycles boot up just fine.

Anybody seen this behavior? I've read some anecdotal reports of problem with Antec PSUs but I monitored the voltages with a multimeter during a cold boot and a warm boot and in both cases the voltages were well within acceptable ranges.

Yeah I have seen that issue be caused by the power supply if your video card has the extra power connector on it. Cold booting though works. Do not know of a fix other than a different PSU.

What do you mean by power-cycle boots?

Thanks for the response. I was afraid it might be PSU-related. Luckily I bought this PSU at Circuit City so I still have 7 days or 23 days to return it (not sure if it falls under the 14-day or 30-day return policy).

Sorry, power cycles and cold boots refer to the same thing.

It could be something else - but a new PSU fixed the same problem when I ran into it.

I have seen this caused by suspend mode - turn it off or increase number of seconds to go into it.

Whatever it is its ACPI related

Hey!
My system also freezes during POST of a warm boot!!!
It freezes with one diagnostic LED of my DFI Ultra-D motherboard, that is during BIOS sequence.
My PSU is an Enermax Liberty 500W, did the author of this topic solve his similar issue? Does somebody have some piece of advice because I am quite desperate!
Thanks!

You didn't tell us what mobo you're using. Have you checked for an updated BIOS?

 

[kapsch]

my mobo is DFI Lanparty Ultra-D as specified in message and sig!
i have tried 2 BIOS updates, 623 and latest for win2k, with no results.
Is my warm boot problem due to a defect harware? it seems odd to me because once i manage to start my system (with cold boot) everything works quite fine.
ALSO, i just tried to insert second RAM stick (i bought 2*1GB G.Skill RAM HZ), and system won't boot at all (neither cold not warm lol). There are also 3 diag LEDs on on my mobo, meaning the system doesn t detect RAM modules.
If i take away the "faulty" RAM module, it works fine again in cold boot....
Does this mean both RAM modules are faulty?
hmmmm

Have you guys checked in your bios to see what settings you've got under power? There are several choices for hitting the power button on your case and you need to make sure that you've got the right one selected or it can go into hybernate or suspend mode.

Hey, thanks for your reply.
I am running my system on "load optimized defaults" from BIOS.
UPDATE:
I tried the second RAM module of my 2 GB kit (I was just using one until now), and the system won't pass the POST sequence (stuck on 3 diagnostic LEDs on my DFI Ultra-D), neither with the second "faulty" one nor with both RAM modules.
I will bring back my RAM to the seller, and see if it was a RAM problem ...
I am PRAYING it was faulty RAM xD

 

[kapsch]

OK, i got my new RAM kit, tried it yesterdaz, i am able to get the Dual channel mode but i STILL have the warm boot issue.
I tried 3 different BIOS versions (stock and 2 new ones), I ran memtest fine, I ran prim95 fine (8 hours). I have an alumium case and an old CRT monitor (dunno if this is an issue or not, i am just lost here)
Has someone had a same problem with cold boot OK, but no go on warm boot?
I need help here! :/
thanks

anyone has opinion/advice on this problem?
thanks!!

It won't be faultly RAM. It might be the PSU, but I would more likely blame the BIOS, Mobo, or the video card. I have not seen this since PCI days where a NIC (Token-Ring) on reboot would not get a drop in voltage long enough to determine a restart was happening. Since the drop in power was not long enough on the PCI bus, the card never reset and stayed 'on'. In this case, the card would not pass network tokens and the Token Ring would beacon until the OS came in and the driver issued a reset.

In that case, it was the PCI bus on the mobo with the card. Suspecting something similar, try a new BIOS first if one is available. Since I have not seen a bunch of nVidia 7800 folks complaining about it, I would less likely blame the video card. Check with DFI and possible post their if they have a support forum.

ok thanks for your answer, i tried everything but i couldn t solve this. I brought my mobo back to seller, he gave me a new one and now everything works fine. i guess it was faulty MoBo AND faulty RAM, OMG i am such a guy without luck!
