Check your manual for the location of the reset jumper, it will mean having to unplug the mains lead and then removing the battery then move the jumper next to the battery from pins 1-2 to 2-3 for about ten seconds or so before replacing it back onto pins 1-2, replace the battery, plug the mains back in power up and enter the BIOS and redo all the settings. whilst you have the side off and the rig powered down check that all plugs an connectors are good and keep your finger crossed.
Damn I am having a very similar problem. ONly thing is all i did was shot my PC down,came home few hours later and tried to boot up and got nothing on the monitor. Lights,fans working,light on mobo working,
but i cant hear the 2 raptor 10k rpm hard drives winding up. had them checked out of PC, was told they seem to be fine. was told by tech at best buy it was graphics card , well i spent some duckets on 2 new 275 gtx cards. Crapola same thing, no difference at all! I bet my old 8800gtx card is good, but i still have no clue whats wrong. So the original poster and i may have the same problem. help us out guys
i tried the ram thing. didnt work for me. i checked the power coming into my mobo and i got a reading of 12.15 volts DC across all pins. tried 2 different GPUs .unplugged all the pci cards and tried it. I have a green light on my mobo that i thought meant it was working properly. I'm at a total loss. Does anyone on here have any clues?
Did u check if u have a 12v atx connect on your mobo,had the same problem when i blew a psu,took it out,got a new one and it dident have a 12v atx connecter on it so i dident notice anything (i though id friend something) then i compaired the two and saw what i was missing so i cut it off the old psu and spliced it onto the new one and everything worked fine
your not all as thick as me but i thought id just share...
1) Did you plug in the power to the graphics card?
2) Did you plug into the right DVI output?
3) Did you connect your Hard drives correctly?
4) Did you put your RAM in the right slots?
5) Did you switch on your monitor power button?
