Hi guys

I bought the parts needed to build a complete new system from here a few weeks ago, everything was fine, the build went well and the system had been running fine untill this morning.
When i turn on the computer everything powers up ,well the fans do anyway, but the graphics card lights (2 little red diodes on the back of the card) continually blink and nothing appears on my screen, The lights blink in a series of 4 flashes (if that info helps?) that continues untill i power off and neither of the dvd drives will open.
I'm thinking it could be a psu problem, but i dont see how this has happened, the rig has been working fine for nearly a month now, with no major changes to devices or drivers etc.
I've tried re-seating the gfx card, using a different 6-pin PCI-E cable from the psu, disconnecting all devices and trying to boot with just the gfx card, and ram, but still get nothing.

There have been no changes to any of the drivers, devices attached, system configiration or anything else recently, the computer was fine last night when i shutdown as normal, but this morning its having problems
Any help would be much appreciated.

Thanks

Do you have another PSU you could try? Even just a crappy old one to see if it boots. Take out the graphics card and leave just 1 stick of memory in and see if it boots. You didn't have lightning last night did you?
 
I do have a crappy old psu, but, it doesnt have the right connector for the psu to the mobo, tryin to find a mate with a spare now though.
I've already tried using just single sticks of ram but no joy there, will try again when/if i find another psu.
Nope, no lightning last night.
