    Default Weird issue with Gigabyte EP45-DS4P

    I had overclocked the machine before this problem but i defaulted the clock speeds after this issue.

    About 2 weeks ago i encountered a weird reboot issue in which i turn on the machine and it kept turning off and on and off and on. I took out all the components including RAM, GPU and other PCI peripherals. The machine turned on with no problem but i ran into another problem. Everytime i turn on the machine, it doesn't display anything until i press reset until about 20 seconds after i press the power button. When i press the reset button, the display comes up with the standard detailing.

    One thing i've noticed is that when i press the power button initially, the PCI Express LED keeps blinking with an additional LED on my GPU blinking. The GPU led blinks three times but the motherboard LED indicating the PCI express remains on all the way into Windows.

    I opened up my Catalyst and it had decreased the bus speed to 1x; down from 16x.

    Going back to the initial problem, if i go into BIOS and somehow make the machine turn off like increasing the volts or decreasing the volts then sometimes it the LED doesn't show up anymore.

    There was one time i decreased the voltage and the system turned off and turned back on but when into the no display issue. So i had to reset it and go to BIOS and click Optimized defaults and then the machine turns off again, but this time round the LED didn't turn on at all on the mobo and the GPU read 16x in Windows. It's not always the case though.

    I don't think it's my GPU as i'm using it now and whenever the motherboard lets me run it at 16x then it's beautiful

    One other thing is that when the PCI Express runs at 1x then i run into weird trouble such as when i turn the machine off then it goes into that same no display issue. However when i actually make it run at 16x then i can turn the machine off and return it back on and it starts instantly but if i do it about 4 times then it goes into the same loop.

    Alot of people were recommending a different PSU but i changed my Corsair HX-620 to a Corsair HX-1000 and didn't fix up the problem.

    I tried taking the ram out and put individual ones in and same problem.

    What do i do? This **** is making me crazy especially when it makes my GPU bus speed run at 1x.

    GPU: ATI FireGL V8650 2GB
    RAM: Kingston HyperX 8GB
    CPU: Intel Q9550 2.8Ghz
    PSU: Corsair HX-1000

    Thanks guys.

    EDIT:

    I took a screen shot of the bus speed when it loads properly and when the LED blinks.

    Properly at 16x

    Re flash your BIOS to the latest version using Q Flash and load optimum defaults.

    Ok but before i do that, why would it be the BIOS? I mean could it have become corrupted some how? It was working great then all of a sudden this goes all crazy.

    Anything's possible. I suggested it because its the easiest place to start and doesnt cost you anything. Unless you have a spare PCI-e Video Card to throw in? I would also just for piece of mind run memtest 86+ v2.11 for serveral passes to rule out a memory issue. Just some suggestions to start with dude.
