Reboot loop on cold boots in the morning.

[Bo$$]

I used to get this if i left my window open overnight..
I put it down to very cold H/D's or condensation inside my aluminum raptors..
My fix was keep the window closed it fired up everytime..
Not saying this is your problem but almost indentical

same here, when it is about 3-4degrees at night it happens here

my gigabyte EP45-ds3 has done it since day one, dosen't matter if pc is overclocked or not, i thought it was my PSU at first so bought a new one and i still get it doing odd things when i power it up.

Don't know if my cpu has anything to do with it, but my ram has never wanted to run full speed either, pc will loop none stop and not even get to bios screen, oh and it bleeps like hell lol.

Also why we are here... you said you had flashed the bios already? Under the motherboard tab of CPUz, does the bios version running match what you flashed to?

 

[trickson]

I didnt use a floppy to flash, I believe there is a guide to GB flashing here have a look, its dated, but the theory is the same.

It's much easier if you have even a small thumb drive

CRAP WHY ME ?? I don't have any of this !

 

[Steve-007UK]

I personly don't think a bios update will help, for me the new bios is beta and totaly screws over my mobo, i have also tryed older versions of bios and it still starts up shuts down then powers on fine.

I could be wrong here but do you have a PSU with its own power on and off switch at the back? if for any reason i have to turn the psi off at the back, my mobo will loop more than twice before full powr on.

Well the bios is up to date once again every thing seems fine for now but who knows what it will do in the morning !

Yes it does .

I'll keep an eye on this, but I still have suspicion it was a bad write. I mean even on a cold boot, mine only cycle the one time.

If it keeps it up after getting the new RAM I hope to get I will try a new PSU and also get a thumb drive to reinstall the bios .

 

[trickson]

Ok well once again it is doing this . I just got the bios loaded onto floppy Q-flashed my bios and will wait till tomorrow . Was really hard to get it going today guess I may have to take another trip to Fry's !

 

[newtekie1]

If you shut the computer down completely, then start it right back up, does it have the same problem? Or does it only happen when it has completely cooled down overnight?

No . This thing was really hard to start up today . but I used Q-flash this time and a floppy to re-flash the bios . So far have been unable to recreate the events . It only happens when it has been off for 8-10 hours . Could this very well be a PSU issue ? as I have had this happen before and do not remember if I changed out the PSU or what to fix this and I remember it was on a gigabyte MB as well just can't seem to remember just what I did to fix it . MAN this is really frustrating . I feel like giving up !

I had this issue with another Gigabyte motherboard. Infinite reboot loops at power on. All of the other parts were fine when I tested it. After testing everything I had to return the motherboard, replaced with another, different brand. Asus. Same chipset. Different brand, no reboot loops with the new motherboard.

Well I just don't know . I hope not I may have to ask gigabyte about this .

Update: Just sent them an email about this . Lets all hold our breath ............

1-You have a water cooling .Check the tightness of the waterblock, may be pressure on the socket is too high.
2-If you flash your bios ,use the jumper and also remove the cmos battery in the same time.I had to do that with my old p35ds4 (dual bios) ,like this your are sure than all bioses are erased.

I hope you solve your problem and don't tear your hair!

Your post just popped the watercooling in my head.

I've seen one time, just once on a friends build, where he had air in the loop that would settle in the CPU block(it was the highest part of his loop). It would only do this when the machine was off for a few hours. Basically it would cause the same symptoms. The air would cause the CPU to overheat and fail the overclock test thing that the board did. Once the loop ran for a minute or two, the air would disperse from the block and the computer would boot normally.

Just throwing it out there as an idea.

OK hold on here , do I take the bat out and clear cmos before I restart and flash bios ?
Because I turned it off for like 30 min and when started it froze up but this time the screen stayed there and no reboot loop , turned off PSU then back on , booted fine .

 

[trickson]

Update : well I loosened up the water block I think I may have had it way to tight . turned system off unplugged and waited for 20 or so min and well every thing is fine , booted right up . fast too .
time will tell .

my p45 does this aswell on its first boot after turning the mains on. everything spins up for a second then shuts off, then starts again and everythings ok

 

[Steevo]

Check your BIOS events, and then try your windows event logs.

Nothing at all in windows events .

how do I check bios events ?

So far I was able to recreate it in some fashion 2 times today mainly unplugging the PSU letting it sit and then turning it all back on . after loosening the WB I have failed to be able to do the recreations , Maybe it was way to tight and that was it but time will tell . Updates as I get them .

 

[Steevo]

In your motherboard user manual it will show you where BIOS events are logged.

Well the system has been off for about an hour and I just turned it on and it booted up fine . well I know one thing tomorrow will be the real test . then I will know for sure .
