Gigabyte GTX 660TI Random Reboots?

[Shenahal]

Hello,

I recently purchased a Gigabyte GTX 660 TI and noticed that my computer now randomly reboots with no hint of a issue before hand (no freezing, stuttering, nothing).

The reason I do not think it is a temperature issue is because it has never rebooted while in a game, it happens usually when I am browsing or if i am just on my desktop doing nothing.

Motherboard: asus p8z68-v pro
RAM: 4GB x 2 ( corsair?)
CPU: Intel 2600k
Storage: 1 SSD + 2 HDD
PSU: OCZ 700W

This all started when I first installed the video card, my only concern is how random the reboots are.

For example: It will not reboot for 2 days, but than all of a sudden it will reboot 3 times in a row every time i get to the desktop then stop for a full day or more. It does not happen while i am doing anything specific it just happens.

It does not look like a defective video card because everything runs so smooth and great! My current guess is it is a fairly new card and the drivers are buggy?

Any help on this very frustrating issue would be much appreciated.


EDIT: Is it possible that the video card is pressed to close to a mother board heat since which causes random restarts?

I have a GA-X58-UD3R and GTX 660ti. I was having similar reboot problems, sometimes 2-3 times a day.

I would like to confirm that flashing motherboard with latest bios through @BIOS and updating video card with the latest drivers solved my problem as well. Not a single restart in over a week

I still did not solve mine, atm changing HDMI cable because i noticed LCD TV is losing signal sometimes for 1-2sec (once a day), also i downclocked the CPU and only after that i noticed black screen signal lost but no restarts

This may work for you...

I had similar issues with what you're describing. I have an AMD AthlonXP 2800+ system with an nVidia GEForce 6200 4x/8x AGP card installed. Similar issues arose with Windows XP Pro, Vista and recently after upgrading it with Windows 7 Professional Edition.

The BSOD screen gave nvdkllm.sys, dxgkrnl.sys and watchdog. sys errors. I couldn't get the OS stable and running for more than 20 minutes. Every time I open a program it gave me an BSOD! I removed and reinstalled nVidia drivers etc. and even reinstalled the OS itself several times.

Finally a solution! I found out exploring the BIOS settings that there is an "AGP Fast Write" setting. So I turned the sucker OFF and/or DISABLED it. On other BIOS settings it may fall under "Caching or Shadowing".

So far I have not had any BSOD video card related problems.

Windows 7 is not perfect, but it's running stable so far.

Let me know if this helps.

Hmmm so it seems there is more than one solution to this issue, for me a bios flash/update did not work but swapping the two cables that connect to the video card did, it has been i think a month now with no restarts.

BTW when i say swap the cables i do not mean the cables were defective and i used new ones. I used the same cables but swapped which sockets they were plugged into, when I first installed the video card I was under the impression that both sockets on the video card were the same so I did not matter which cable went into which socket...buuuut I guess I was wrong..

I fixed my restart problem, it was faulty HDMI cable 🙁
hard to track i did`t know bad hdmi cable can work fine but make PC unstable
