Hey people,

please hear me out as i am not a computer guru and i will try and explain everything to the best of my ability

i can see on google that there have been several issues like this covered and of course i have logically followed steps people have suggested but have had no luck

my nephew has built a gaming PC, it was running fine and then for some reason he decided to reinstall windows, he done this successfully and then when it came to installing his MOBO drivers he noticed the disk was severely scratched, he then downloaded the drivers off the net and upon rebooting the PC now gets no video. Which is why this issue 'MAY' be different to others. There is also no power from the USB ports!

so....the spec of the PC is as follows (again im not a computer nerd)


- Asrock 970 extreme 3 mobo
- geforce GTX 760 graphic card
- avexir 2x 4GB DDR3 ram sticks (slots 1 & 3)
- 650W PC-650AUBA-M power supply
- corsair heatsink - water cooled??
- kingston 120GB SSD (for OS)
- 2TB 3.5" sata HD (not connected was used for storing games)
- i dont know the CPU as i didnt note it down (AMD though)

So its not hard to see that by google searching '970 extreme 3 no video' there are lots of issues like this plagued over the net but again im thinking this one may be different.


The things ive done are:

- ensured the 8 pin 12v connector is attached to the mobo
- removed the mobo and madesure the stand offs are all lined up correctly
- removed the CPU and checked for bent pins
- reinstalled the CPU ensuring correct orientation
- reinstalled the heatsink on the CPU with fresh compound using the 'pea method'
- obviously ive disconnected everything and reinstalled it all (plug wise so no loose plugs)
- reset the cmos by using the jumper and removing the battery for 5 mins
- tried booting using 1 ram stick (and swopped them around too)
- tried connecting it via DVI as opposed to the HDMI


i dont have a speaker so i cant check for beep codes that ive seen some people suggest

i might try reversing the reset switch when i get home as ive just read that this may cause an issue? although these plugs have an arrow pointing to the negative wire iirc to help with orientation?

i havent tried putting the ram sticks in different slots (they are in 1 and 3)


from my previous messing's with PCs (we're talking 5 years ago) id like to remove the HD and format it so that its basically like a new install but i havent tried this yet


any suggestions would be awesome and ive taken some pics and a quick vid also if theyre any help

Hi,

Is there no output to video at all, or does it show the BIOS splash screen and then go black?
As the motherboard doesn't have any video output (ports), you can't test if it's the graphics card drivers.
If you happen to have a graphics card that is the same brand (nVidia) then try this instead of the current one.

Hi there

There's no video output what so ever, no bios flash screen nothing

It looks like I'll have to try a different graphics card (although it's weird how it would suddenly die)

Swopped polarity of the reset sw and there was no change

Reformatted the HD & still no change :(

I know it sounds odd, but have you tried a different monitor?
Sometimes things like this help :p

Just to confirm, have you tried everything in the following checklist:

yup, well the only two things i havent done on that list is:

- try different ram slots (theyre in 1 and 3 atm, i could try booting with just one stick in slot 4)
- install speaker system, i have a button speaker that my nephew will give me when i see him next

other than that ive done everything, that is the inital list i followed.


i need to get my hands on another GC, as soon as i have one i can start going down that route.

It could still be the motherboard, as there seems to be bad problems with these boards. If the graphics card route doesn't work, return the board (depending on where you got it from), or RMA it to ASRock.
Sorry I can't be of any more help.
