uhhhhmm.....someone with more knowledge should also post but... if it was me...
I would check to make sure that the PSU is hooked up correctly (not saying you're dumb or anything, but it's easy to overlook stuff =D )
Since you get no visual you wouldn't be able to see it, but listen for the RAM check beep.. you may need to reseat the ram (pop em out and back in)
With getting no display i would just pop the GPU out, make sure the contacts are clean and reseat it, again making sure that the power to it is good (if it needs an external power source)
i don't know if this would cause this issue or not, but since you intended to replace the GPU with an Nvidia card (you said the 9500) was your old GPU an ATI card? Did you remove the drivers?
again, someone with more knowledge should also definitely post =P
If I read the OP correctly then I think a CMOS reset wouldn't go amiss as trying to SLI a 9600GT with a 9500GT may have confused the mobo and/or the display driver.
how u do a CMOS reset then? cause i ain't got a scooby lol
well took the RAM out and put it back in again, same old results. CPU working, case fans working, everything looks like it's running smoothly but no load up.
Possible i took the hard dive out or somthin? or blow up the RAM like an fool lol
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?
