I need of major computer help

[Rehont]

I know there are a few computer buffs that surf the bg forums *cough sonomaa *. Anyway ... about a week ago I had a power surge that took down my computer. When I hit the switch after the surge, all fans would kick on but nothing would appear on the monitor. No bios beeps or memory check beeps or nothing. I replaced the video card, power supply and motherboard ... and still having the same problem. The only thing I can think of to replace now is either the processor or the memory .. seeing as those are the only 2 I havent tried yet. I took all the memory out and tried booting it up to no avail. Any suggestions?

Old specs

Video Card - GeForce 6800 Ultra PCI-E (replaced with a Radon something PCI that a friend had for me just to see if it was indeed my video card)
Motherboard - Gigabyte LGA775 Intel 945 PL (replaced today with a Neo2 from MSI LGA775. Used the same processor from the Gigabyte)
Processor - Pentium 4 D 3.4 gig

I have no idea what I am doing wrong .. all the wires are ran correctly accoroding to the owners manual.

*edit* yeah I know I worded the title wrong ... too frustrated to care about it right now

The problem with power surges and running no protection means every part in your computer can possibly suffer damage.

The power supply is usually the component which bears the brunt, but you've already replaced that.

It's hard to say which of the two pieces left may be damaged; could be the CPU, could be the memory or it could be both. Do you have a secondary PC or a friends PC with your memory spec connections you could test the memory in?

If I was to gamble between the two, i'd day the CPU is damaged simpy since you didn't a warning beep error for faulty memory, which your motherboard won't even get round to testing with a faulty CPU.

sounds more like the proc at this point, think about it this way, you would get beeps if it was the ram you'd get 3 or so depending on the mobo saying "hey guy theres no ram here" yet you get nothing, it could still be both but the fact that you get nothing when you remove the ram says its probably the processor

after you replaced the mobo do you still get power to the fans when you hit the power button?

also buy a surge protector, they are cheap, or even better buy a UPS more expensive, but better as you wont lose data since there should be enough battery so you can save/turn off everything

What killg said, it would still try to boot and complain if it was the RAM, you have replaced everything else so you can safetly assume you CPU is screwed (Doesn't mean you ram isn't screwed as well)

still boggles my mind that people won't spend 10 dollars on a surge protector.

What people have said, try to test the last two components on another PC and see which works, most likely it's the CPU but you never know. Best thing to fix is your brain for leaving hundreds of dollars of PC equipment at risk for not springing a few bucks worth of protection.

Thanks for the advice (and uneeded sarcasm from one). I DO have a surge protector which is why I am frustrated at my system completely crashing. Dont jump to conclusions. I do have a back up system .. the one I am currently using but its a SDR mobo .. not a DDR2 and its a different socket/chipset as well ... so cant overly test the processor either. I had narrowed it down to the processor but I wanted some advice from people who had more experience than what I had. Thanks again

*To Gannon* I agree I need a battery back up as well .. its on my list of things to get. And yes .. after I got the new mobo in and wired up .. all the lights and fans came on including the processor fan but no Bios beeps or memory checks
