REGARDS BoB
 
Try booting with just one stick of RAM installed. Also have you made sure the CPU power connector is installed? If it's not posting then I suspect the issue is either power or memory. Your other PC is running an E4500? That's a great chip by the way :) Old but good. Anyway....
 
i was going to say check that you've hooked up the 6 pin PCI-e connector but if u've tried the card in another pc im assuming you've remembered this...

got another monitor or tv to try?
any beep codes on startup?

edit- as above check the cpu connector i've forgotten that 1 before too!
 
Random I know but you did you stand offs right? They are the brass coloured 'legs' that go between the mobo and the mobo tray on in the case. Have you tried reseting the cmos? To do that you just remove the 'watch style' battery for a minute or so.

Is the pc powering up? or just the PSU?

Are there any leds on the mb that you can see powering on does the dvd drive open close?

CPU fan / grfx fan start up or other case fans?
 
the gfx is in the correct slot yes ive taken the battery out and placed back in and the brass stand offs on correctly,

on the mobo it does power up and the led lights are on display work fine , all fans work and power up fine no loss of power at all
 
is the grfx card definitely in the slot? pci-e cards can look like they are in but have slid down next to / but not in the slot.
 
Can you test any parts on another pc.

ie, PSU and GPU.

Can you confirm the 8 pin for cpu power is connected as well as the 24 pin ATX connector :)
 
have you tried running the graphics from the motherboard only and taken the grfx card out?

Click to expand...

His mobo doesn't have onboard graphics.

This might sound silly but have you tried plugging the monitor cable in after turning it on? (I had something a bit like this happen on my cousin's PC)

Does your case have a speaker btw? Starting to look like if you have one it would be nice to know what kind of post beeps you are getting.
