Computer fails to POST.

Hi everyone,
I have a computer that i have been using for 1 year and had no problems with it whatsoever. i moved from europe to the US and brought the comp with me, but now it would not run.

When i turn it on, i can hear the sound of the fans running and the lights would turn on but the monitor gets no signal and the fans don't slow down- No POST, nothing on screen, can't get to bios.
I got a voltage converter to upgrade 110v to 230v, it didn't help.
I tried running it with the minimum parts, nothing worked. I took it to a technician and he charged me $40 and told me that it is definitley the motherboard. I just spent $120 on a new motherboard and i am facing the same problem!

So i figured it is either the PSU or the CPU now, can the CPU cause this? Is there a way i can check which part is faulty other than buying new ones? Any help is appreciated, i am on a tight budget and don't want to replace perfectly working parts


Thanks.

I would suspect the PSU before the CPU. Doesn't your PSU have a switch in the back for 110 and 220? Buy a new PSU.

that link opens the general forums, jsc maybe i am missing something?

I am using a http://www.thermaltake.com/product [...] /w0117.asp it does not have the switch in the back. i will try getting a new power supply and see how it goes. thanks people

if it is not the PSU then it might be the CPU.
stupid question, can the CPU be damaged passing through several x-ray screening belts ?

I have gotten an OCZ PSU

And it didnt seem to help with the problem, i also swapped out my 8800GT for a 8600GTS, still nothing would come up on the monitor even though my computer is running.

So i decided to go with a new Motherboard/CPU combo, can anyone recommend an AMD CPU/motherboard combo that does not break the wallet?
Will be used for moderate gaming, i was thinking Athlon ll x4 but open for suggestions
