PC won't display anyhting after rebuild

jonislost · 26 Nov 2009 at 08:41

Just got some new components for my PC: CPU, HDD, and extra ram. So I thought I'd take the time to just completely strip it back, tidy up the cabling, and install the new components. Now everything is back together and when I switch it on nothing displays on screen, although every device seems to power on (all fans inc graphics are spinning up)

Things I have tried (and haven't worked...):

- Running via One stick of known working RAM
- Running with no RAM at all (no error beep occured :S)
- Running with one stick of ram and one known HDD and DVD
- Running an alternative graphics card in the same slot (only one PCI-e 16 lane avail)
- Reset CMOS

Does anybody else have any ideas?

Companents:

Gigabyte GA-P35C-DS3R
4GB 6400 RAM
8800GT 512mb (also tried 7600GT256mb)
1TB WD
Q8300 CPU (with stock fan)

Reset CMOS?

+ Have you installed both 4pin and 24 pin atx connectors?

Try a different PCi lane.

Yes both are plugged in and I've only got one PCI-e lane availible and I haven't got any other type of graphic card other than PCI-e to test it unfortunatly.

My thinking is that its the PCI-E slot for whatever reason, seeing as two cards fail to work

Yes, i see.. I just checked the spec

Have you checked the monitor and the monitor cable on another system, to eliminate them?

Yeah just tried and it works fine

It was all working before I decided to fit a new CPU. I cant thing of any physical trauma I expelled onto it

Have you tried reverting back to the old CPU?

My thinking is that it maybe the PCI slot, or the NB.. either which the Mobo may have gone.

Try making sure that your hard drive is plugged in. Previously mine was out about 2mm's. Took me ages to find it, plugged it in. Booted straight up.
