Computer issue, gonna link you to my questions; maybe one of you can answer them because I'm confused as hell.

Right now I'm going to try to swap in a ancient pci graphics card and see if windows will boot / get any sort of video feed.

no video feed.

what 680i board do you have? my DFI 680i UT has died 3 times until i went with another board.

try removing the cmos battery to revert to defaults. i know in some BIOS you can set your video to only pci-e, etc. your pci card may not be able to enable itself.

another thing - even though you were overclocked 10-20% what were your voltages? I ended up frying my cpu from too much voltage and at first i got laggy-ness in games and then it would lock up, and then not even run at stock speeds.

try unplugging everything except what is required to boot the pc, unplug cd drive, floppies, all usb except keyboard, hard drives, sound card or any peripheral devices minus a video card (unless you have onboard video!)

Pretty sure it's an asus nvidia nforce 680i.

It was AI Overclocked setting(mostly just for CPU) and I swapped the CPUs with my parents computer(since they have a 6550 core 2 duo and i have a 6600. Works fine. Heat wasn't an issue like I said, I'm watercooled. I was at like 2.88 or 89 ghz from 2.4, which isn't even that much. I did try overclocking my ram to 4-4-4-12 but blue screen multipule times which didnt make sense because people have overclocked from 5-5-5-12/18 to that with stock voltages. I put 2.1v (max) and worked until first MW3 game then froze up and blue screened, then I reset everything in BIOS back to stock speeds and nothing.

I was going to wait till tomorrow to do this, but screw it ill just get everything set up now. Gonna take everything out of case, and set it on my wooden desk and see if it will boot

Recap:

PCI Video card - no video
PCI E GTX220 - no video
PCI E Radeon 9670 - no video
PCI E 8800 - no video

Tried different slots

Put 1 stick of ram in each slot, switched to other stick, repeated.

Pulled battery out over night - set jumpers to reset.

CPU works fine in other computer - along with RAM.

All 3 PCI E cards do NOT work on either computer.(really confused considering 2 of the PCI E cards came from working computers)

The PCI card WORKS in my parents computer but not on mine.

Either "Failing" PSU or Dead motherboard?

Does the MoBo get power when you turn the computer on? If so, if you have eliminated most of the typical issues it could be, then it will most likely be a less typical/known issue. My guess is if you can't post, but you know the CPU, ram, PSU and GPU are all functioning and the MoBo is sending power to everything (the GPU fan will be spinning along with then CPU heatsink fan), then your issue lies in the BIOs chip for the MoBo. If your BIOs chip is fried, the computer will never POST and therefore never boot or even display a screen.

Everything else works. I took my video card out (since its not a integrated motherboard) and it had a long pulsing noise like a beep

I had a similar problem with my asus p5n-d nvidia nforce 750i sli. First assumption is that it is most likely the video card. But i found that moving the card to the 2nd sli slot would bring back the video. Then after a while that one started getting flakey as well. Turns out that when you put a load on it, the board heats up and warps, breaking the contacts with the sli slots. It got worse and worse as time went on. I finally ditched the board and bought a new one and all problems were fixed.

Well I would suggest upgrading since everything you are using is outdated anyway, also you are using a Core 2 Duo CPU and a DFI MoBo. That CPU socket is most likely long dead (I am an AMD guy but I am sure it is still obsolete) and DFI doesn't even make MoBos anymore. Go grab yourself a whole new setup, wait for black Friday and go to town on Newegg. A MoBo, CPU, RAM combo will be real cheap then.

Also avoid buying HDDs right now as they are stupid expensive because of lack of materials due to the Thailand flooding.
