Computer won't boot to BIOS, just black screen

[biro]

Hi
My computer is running windows 7 64 bit with a Foxconn G31MX Mobo.

When I boot everything seems to go fine, all the fans run and leds light up etc, but there are no beeps as I would expect and the screen is not receiving a signal.

I have tried a different monitor and replaced the mobo with a new identical one.

Any ideas what the issue is, I would have thought I would get to BIOS at least unless it was the mobo, which I have replaced.

Thanks in advance

What RAM do you have installed (specific model #)?

Is this a new build or is this a system that you've been using for a while?

Have you tried booting without any drives connected?

Check that your CPU power cable is fully seated.

Thanks, I will go through your check list tomorrow, but things I know already...

He has 2x • RM25664AA800.16FG - Rendition RM25664AA800.16FG 2GB PC2-6400 240-pin DDR2 SDRAM DIMM.

It is an old system that I upgraded, probably a year ago or more. The problem happened when my son brought me the base unit so I could upgrade his ram, as it turned out he was already at his max 4gb and I didn't have to do any more. It is possible he was a little too rough with it after being asked to do something, bless.

I am sure the cables are seated properly.

I will try rebooting without peripherals tomorrow.

Thanks again

I have had this problem many times, I'll try to help you out.


STEP 1-Turn off your PC and remove the power chord
STEP 2- Remove the CMOS battery for 60 seconds
STEP 3- Hold the pc power on button for 15 seconds.
STEP 4- Put back in the CMOS battery
STEP 5- Plug back in the main power to PSU
STEP 6- Enjoy

Incase you are not sure what the CMOS battery is

Sounds like a burned out Cpu/Motherboard to me.
My old computer died like this. I also had another computer which the same happened and I managed to explode the PSU.

Update: didn't see the date of OP, sorry if i bumped.

All I had to do was reset the clock to something close to now and all is well. The fact that the clock was so far out it messed up everything.

Thank you all for your advice

If that's the case do i recommend to replace the motherboard battery which keeps time when the pc is of power.It doesn't cost very much so not a reason not to do it.
After replacing it make sure the time and date in the bios are set right and the bios is set to optimal default values.

the steps RESET all clocks to normal(default) value which would have solved the issue and is the reason for a CMOS reset.

Awesome thank you

Since taking the battery out with those steps is it just as wise to replace it.
