Hi all

Well nothing changed in the last 3 weeks.

Last night i put the pc into sleep mode.

This morning i hit the spacebar and it just restarts non stop,not even a logo on the screen just blank and keeps restarting every 1sec .

Cmos was reseated and the ram,power to the board was plugged out and in again.

Gtx680
Asus p8 board
8gb kingston hyperx
Ssd samsung
1tb samsung
 
Don't know if it's significant but I had an Asus P8H61 die on me last week, posts as far as Asus logo "hit Del for BIOS blah blah" and that's it :(

It's a LGA 1155 pcb, fortunately Takealot have a MSI alternative listed and it's on the way :)

Meant to add that it was also exhibiting problems booting for a couple of weeks prior ...

"Typically if it is a CPU failure the only way to check is by getting a 'spare' CPU to throw in the system. Not many people have a spare CPU floating around. Heck, with all the spare parts I have in my house I don't think I have anything newer than a Core2Duo available as a 'spare'. CPUs do not tend to die, so it is not something you generally keep on hand for repair work.

for the motherboard itself it is mostly a visual inspection. Look for bad caps, scratches, discoloration, buildup of any salts or other compounds, water damage, etc. If everything looks fine, then the next step is to 'bread board' the system. Plug in ONLY the power, CPU, CPU fan, RAM, and video cable (and video card if there is no onboard video). Remove anything and everything else from the system. No other cards, USB device, network, audio, nothing. Find the pin-outs for the front panel header (can be found in the repair manual on Dell's website) and use a screwdriver or paperclip to short the jumpers for the power button to turn it on. If it turns on and you get a keyboard error for fan failure warning then that is a good sign. If it does not turn on, and you know the other parts are good, then your motherboard is bad. Then start pluging in one or two things at a time and try booting it. When you plug something in and the system stops booting then you found the problem."

I had a similar problem and followed the advice above it turned out to be my reset button of all things.
 
Had it happen to me once. Turns out is was a crappy reset switch that got stuck and kept resseting the pc.
 
Oky found the problem but it doesnt make sense.

So i had a gtx 680 SOC in on a 550w(guessing the psu was to weak actually)
Replaced it quick with a spare r9 270 laying around it booted.

Is the gtx 680 still oky though?cause i dont have spare psu's to test.
 
Dont put a gaming PC into sleep mode, it causes all sorts of problems.

It seems unlikely that the gtx 680 is drawing that much more than the R9 270 when you're not gaming. Your problem could simply be corrupt nvidia drivers. The R9 working in the same slot with same psu in basic windows is cause for hope.

You've probably done all this, but have you:

- Uninstalled nvidia drivers completely while using R9, then rebooted with gtx 680 to windows with its basic vga driver? If okay then installed latest nvidia driver?
- Deleted swap file and after reboot recreated it. Swap and hibernation files have File Allocation Tables similar to hard drives and these can become corrupted during power loss, windows crashes etc.
- Done a basic check that windows install isn't corrupted?
- Done basic check that hard disk drives have no corruptions and/or bad sectors?

Any or all of the above could be responsible for the symptoms you experienced.

Voltage fluctuations could have damaged the card.

OP, do you have another system that you can test the card in? Based on your description (reboots before the logo screen) it doesn't sound like a driver issue to me - more likely hardware fault (PSU or Card).

I've also found that some equipment is more sensitive to under voltage than others.

True that. I somehow completely missed that OP didn't even get by BIOS checks.

Sadly i dont have a extra system or know anyone that has one :/

the system starts and 1sec later just dies and tries to boot again,over and over again? u have a 550w corsair,the card on GB website states it wants a 650w?

Check the plugs connecting the psu to the motherboard. There are two of them, one with 4-6 pins, the other with 12-14 pins. Check they are both seated correctly
 
Have you tried connecting the PC to another circuit in your house?

550w is enough as I am running a 500w with 950gtx
 
You can try unplugging non-essential hardware like DVD, extra HD etc then try boot your machine successively plugging things back in as you troubleshoot.
