GA-EP35C-DS3R random reboots


I have a new build that is randomly rebooting itself anywhere from every 2 - 60 seconds. I get the standard "good" post beep and then the system will reboot itself. Sometimes I have enough time to get into the CMOS and other times not.

The system specs are as follows:

Motherboard: Gigabyte GA-EP35C-DS3R
CPU: Intel Q6600 w/ G0 stepping
Memory: Corsair TWIN2X-4096-6400C5 kit (CM2X2048-6400C5-G matched pair)
HDD: 1x Samsung 250gb (SATA II)
2x WD 750gb (SATA II)
Video Card: MSI RX2600XT T2D512EZ (ATI)
Case: Microcenter PowerSpec
PSU: Cooler Master 600W

Any help would be greatly appreciated. Like I said, this is a brand new build and as such doesn't even have any operating system on it.

    Thanks for the input Ben.

    I ended up getting another case & psu and building the system on the "bench" first, before sticking it in the case. However, while I was taking the system back apart, I did notice that the video card came out rather easily so I believe that it not being seated properly was the culprit.

    I knew better than to assemble the system without bench testing it first, but I was anxious to get my HTPC up and running, so I took a chance. :0)

Hi Buzznode,

First things first - once you have all the components properly seated (sometimes if a RAM chip or CPU heatsink/fan isn't quite right it'll cause those problems) clear the CMOS entirely. There should be a jumper somewhere near the CMOS battery - move it from the 1-2 seating to the 2-3 (with the system powered down) and count to ten. Move it back over and then try booting up again. If the problem continues, swap the memory chips. Otherwise repost once you've tried the recommendation.

My Dell Precision 670 randomly reboots. I thought it may be the power supply, but it seems to only happen when I use Firefox not IE; but that could be a coincidence. And occasionally, the reboot is quite...

Before you go to the trouble of changing/repairing the motherboard. You say that in IE its ok but when in firefox you get the reboots. If this is the case then i suggest you disable all the add-ons you have in firefox and see if this solves the problem. if it does then enable the add on's one at a time until you find the one thats causing the reboots.
I cant say that i have ever heard of firefox causing this type of problem. You dont say what version you are using. maybe if you uninstall firefox and install the latest version it may cure it.

My power supply went down, i put a new one in but it is a 20 pin the gigabyte is 24 pin,it fits but will not work, have i got to use a 24pin,i was told a 20 will work,i hoe u can help

Hi davids38,

I really recommend getting a 24-pin adapter Power Supply Unit (PSU). I had this problem once and did purchase a 24-pin adapter for my 20-pin PSU but my computer wasn't stable (random reboots and lock up). I purchased a 24-pin PSU and my computer worked fine ever since. Hope this helps.

Crash and reboots randomly

Carefully wriggle wires on the back of the PC, one at a time. A card (like video) could be loose. Also, make sure the heatsink/fan is clean, and running. It might be time to reinstall your operating system (I bet it is microsft). If you have another HD, you could install windows on it in your sys, and see what happens.

Constant reboots, replaced most parts

check the capacitors on the motherboard near the cpu and ram. They're the little round cylinders found all over the board. If the tops are bulging out or there is a brownish goo coming out of any of them, this is your problem. Normally the top will be perfectly flat, but if the capacitor has failed it will do what i mentioned above. Sometimes, if it hasn't failed completely, it will cause the motherboard to reboot randomly. I would definitely replace the motherboard if you find this and it should fix your problem. While you're at it, buy another motherboard and CPU and build yourself another entire computer because all those other parts you replaced are still probably good.

Restart problem

Hi mewada,

If the system is rebooting itself, it may not be an issue with the drivers - there may be a hardware issue or an improperly seated CPU fan or other peripheral.

I'm not sure from your problem description whether you're able to get into Windows at all - does it just randomly reboot, or does it Blue Screen and never let you in at all?

If you're able to get into Windows and it reboots now and then, try installing the proper CPU drivers. For many games and some other applications, dual-core AMD CPUs require a specific driver. There's also a dual-core optimizer you may want to try. Check at the top of this list.,,30_182_871_13118,00.html

Otherwise, please be more descript as to when the system reboots and (if you know) what you think you might be doing when it reboots. Faulty memory (RAM) modules and CPUs are the main causes of systems rebooting (other things are generally at fault for freezing up or blue screens).
