No monitor signal problem, computer still boots.

post #1 of 10
Thread Starter 
Hi, not sure if this is the right place to ask.

I've just built a new computer, and it worked for around 1 day, but I turned the computer off and manually set my RAM to a higher speed (the speed it's supposed to be at, it was at a lower speed than advertised). Everything seemed to be working fine, then I noticed my RAM was in single channel mode, so I turned the computer off, unplugged everything and put my RAM into the recommended slots the motherboard manual suggests. I then tried to boot up, and I had no monitor signal, I've tried basically every fix google can throw at me.

- I've changed the RAM slots back to its original state
- Tried one stick at a time in all slots
- Reset the CMOS by the jumper and the battery
- Pressed the memok light 'till it starts to flash then wait for it to go through the sequence but it just goes back to its original state
Probably some other things too, but I can't remember it all.

Was putting the RAM at the speeds listed on the sticks the cause? And is there a fix I haven't tried yet, or do I have to get a replacement?

Thanks.

Some monitors require you set the source for the display.
I know it seems like a no-brainer, but it's not the first time.

Good luck.

Re-seat the card, check the BIOS make sure your display priority is set to PCI-E and not onboard, even if the board doesn't have it, check anyway. Check your cables at both the monitor and your card, especially if you're using adapters. (I know these are simple things, but, we all know Occam's Razor.)

First In my old desktop, I use onboard card

Second, I dont know how "check the BIOS make sure your display priority is set to PCI-E and not onboard, even if the board doesn't have it". But yesterday, when I built my new rig, I open my old desktop but juat take a look and dont touch anything inside the desktop. So im pretty sure all display are in their place

I have unplug and and plug in the cable between the monitor and desktop 6 times. still no signal

How can I set the ram to the correct timings without the monitor to see my bios, is there any way? I've tried the jumper and mobo battery to reset cmos, don't know if it's related to that. I also got an error code while stress testing on prime95, something to do with rounding to 4.9xxxxxxx when it was expected to be lower than 4 or something along those lines, can anybody shed some light on that error code and whether it's related?

I've taken everything out, and reseated the graphics card, and it worked! but now I have a bigger problem...

I turned the computer off for the first time after it booted up, and then I tried to reboot it later on, and it keeps restarting after about 5 seconds from pressing the power on button, and there's no signal to the monitor again.
