I recently updated my motherboard, processor and memory - for the interested:
ASUS P5L-VM 1394
Intel Core 2 Duo E6400 (2.1GHz)
1GB Stick Corsair DDR2 RAM
Formatted the PC and it all worked flawlessly - very smooth, even with the integrated GPU. I then ordered a new graphics card - eVGA NVIDIA 7900 GTX - here is where the problem starts...
I am a little ashamed to admit this - it was a completely stupid thing to do...not to mention costly!
I turned the pc off and pulled the tower out. I opened the side and got on my back armed with my shiny new graphics card. As I started to plug the card in the PC suddenly powers up and then down again, at which point my heart sinks and I realise what I have done...
Dont ask why but I had forgotten to unplug the power from the back of the PSU - I KNOW ITS A ROOKIE MISTAKE!!! - and now I have a lifeless PC... :(:(:(
Anyways, the power button didn't work and I frantically tried to get it up and running again to no avail...so I decided to order a new motherboard which came today. I have just installed it and connected everything up and guess what? Nothing :(:(
Now I am £100 lighter and have absolutely no idea what is wrong with my PC. I thought it had to be the mobo as there was no power going anywhere, it would still start up and freeze if the proc and/or memory were dead right??
So now comes the question... How can i get my PC back up and running cheaply?? What should I start looking at? It is a brand new abit AB9 mobo so I can almost guarantee there is nothing wrong with it. I have a 400W PSU with a 20-pin connector....Could this be a problem? The mobo has a 24-pin connector and the manual says you might not be able to boot with a 20-pin although it will work...
Could the PSU have been damaged? Or am I looking at...*takes deep breath*...a new processor and/or memory stick?
Can anyone help?
Appologies for the long post....thanks guys!
