Hi,

My system has just completely stuffed up. When I press the power button, it no longer posts and continually reboots every 3-4 seconds.

The rig consists of
GX58A-UD3R
i7 920
Corsair XM3 PC312800C9 3x6GB
Corsair HX620W PSU

I’ve tried to get a post using just one stick of ram but I get the same results, tried all three sticks and still the same.

I’ve removed the graphics card and hard drives, still no joy.

Removed absolutely everything apart from mobo, cpu and memory. Still the same!

Reset the CMOS, with no effect. I’ve just taken the battery off the mobo to see if that make a difference.

Strangely, I removed the 2x12v connector on the mobo and it didn’t post, but it also didn’t reboot...just hangs on a black screen. Possible it could point to a psu issue... or a cpu issue... or a mobo issue... I have no idea :(

This is all new kit that’s under a month old. It’s 1:45am here and I’ve been working on this for hours as well as being on call for work, with people in the US calling me up about their end user issues and I’ve got the bigger problem going on here! Aaaggghhhh!!!!


Can anyone help me please? What could be wrong? And what should I try?
 
You could be having mobo issues because a similar thing happen to me. Try the RAM in different slot. I had a faulty slot on a mobo once
 
Thanks Shakeel - tried this but still the same issue. :( :( :(

So stressful, never lost a machine like this! Do I have to go back to OC or the manufacturer to get this replaced?
 
The CMOS is probably corrupt. reset it with the jumpers on your motherboard. The manual will tell you how
Edit: By this I mean not by the battery, actually using the reset cmos jumpers on the board
 
I had a similar problem with a pc build recently. Took everything out thinking it must be the motherboard, but actually it ended up being the RAM.

Have you tried just having one stick of RAM in any of the slots? If that doesn't work try one of the other sticks. I found one of the memory sticks didn't like the default voltage of the motherboard, yet the other one worked fine (and this was from a dual kit).

Gone at the days of jumpers :)

The mobo has a reset CMOS button, I've tried this and it didn't help.

Thanks anyway

Tried all the slots with all different combinations of sticks. Still no joy.

I've asked OC if they can get the ball rolling with a RMA. I've never done one of these before. Does any one know what the deal is with one of them?
 
only time ive experienced this was when my friend built his first rig (before i had built any, and wed only seen it done once). We realised that since hed got an OEM cpu he didnt have a cpu cooler, and as such the chip was instantly overheating and the machine was rebooting to protect it.

Needless to say that was the last time we relied on that person "to get all the parts we'd need" as well as never making that mistake again.....can't believe we just didnt notice for about 10 minutes lol.

The thought had crossed my mind, but I’ve tried without any CPU in the mobo and it still does the same :( :( :(

I’ve reapplied the paste and reinstalled the CPU and heat sink. Still doing the same
 
thats a bit annoying then.

So, the only thing that stops it rebooting is not having the 2 4pins (8 pin) plugged in? And youve tried without other stuffs connected, and also resetting the CMOS?

yep I've set it up with just the mobo and psu and still getting the same.

I'm not sure if I've reset the cmos correctly, what I did was power the machine on and then press and hold the cmos reset button. I've spoke to a college at work and he informs me I need to press and hold the cmos reset button and then power on... is this the correct way to reset the cmos on a gigabyte? Am I doing something wrong? :confused:
 
OK here’s an update:

Contacted OC and they said it could be the mobo or psu. As I didn't have a spare psu to use, I used a multimeter and checked the voltages. They were all fine.

Received the RMA number on Wednesday. Posted the mobo on Thursday. Received email of receipt on Friday morning. Was tested and emailed results by lunch. Received dispatch notification after lunch. My replaced unit is now on its way to me :D :D :D I hope it’s here by Monday

That is some awesome service! OC you are the best!!!!!!
 
excellent. You did some good diagnostic work there. CMOS reset buttons, ive never worked out how to use mine, although when i move my pc it seems to manage to reset itself sometimes, so i guess its just pressing it when its off. Taking out battery and unplugging from wall, and pressing the power button is a sure fire way of resetting it though.
 
Long shot but I had this once:-
The tiny micro switch on the front of the case (power on/off) was knackered. Press it in to switch on and it stayed in - sometimes - boot, boot boot ...:rolleyes:
Try disconnecting it from the mobo then try to fire up the rig by shorting the power pins on the mobo with a screwdriver.
