What gpu do you have and what monitor?

This plus, if that doesn't resolve the issue, i'd try uninstalling the drivers for the card, removing it from the system then give it a good clean with compressed air, resit the card and install the latest drivers and see if that works.

Hi thanks for the fast response. I tried as you said and unplugged the PSU from everything but the motherboard and still there was no beep. I actually have a spare motherboard and Q6600 at home so in the morning i'll fetch it and plug it into the PSU and, if it beeps, then i'll know it's the motherboard and, if not then surely it must be the PSU?

Hi everyone, I have an i7860 OC'd @ 3.8ghz wiith a CoolIT A.L.C. liquid cooler, 8gb Corsair DDR3 1600mhz, 1tb HDD 7200rm, 2 x MIS GTX 470's in SLI and a Cooler Master 1100w psu. Over the last month the PC's been having an issue whereby when I first turn it on, after about 2 minutes the screen just goes black and the system becomes unresponsive. Once I restarted it, the machine ran perfectly fine. Anyway, Today, I packed the machine up and took it to my folks as i'm on dog sitting duty for the next week and when I arrived I connected it up to the television in the living room and, apart from the usual black screen crash, it worked fine. However, two hours ago, I started it up again and...nothing. It sounded like it was starting up as usual (except no beep from the motherboard). I could hear and feel all the cooling, gpu and psu fans spinning and the HDD platters but the screen just wouldn't come on at all or register that the PC was even connected. I tried taking the GPU, RAM and HDD out and resetting/connecting them. Tried putting only 1 stick of ram back in and one GPU but it still just does the same thing. I've used different power points and a different moniter but the computer just seems completely brain dead. If anyone has any suggestions, they would be greatly appreciated.
