OK, firstly I need some specs please - cpu type, motherboard make/model, video card & ram specs etc.
Also the fact that the board, fans & drives have power to them DOESN'T mean that the power supply is adequate. It probably is fine but let me know what it's power rating is anyway.
Secondly, can you explain what you meant when you said 'the hard drive doesnít boot up all the way until I unplug the Ide cable'.
By 'boot up' do you mean spin up? Are you unplugging the IDE cable while the system is still powered up?

Wear an anti-static band or discharge your static by touching a metal surface.
Disconnect the external power lead from the computer, then disconnect the main ATX power connector from the motherboard.
Remove then reinstall the AGP video card. Make sure that the video card is fully & evenly inserted into the slot. If there ia a plastic retention clip at the end of the slot, then this must be clipped into place.
Make sure you have the case/system speaker or buzzer connected to the motherboard
Remove all the ram modules then reinsert just one of the modules into ram slot 1.
Locate the jumper (JP1) nearest the cmos battery. Move the jumper cap so that it covers pins 2-3 & leave in place for about 30 seconds. Then replace the cap so that it covers pins 1-2.
Make sure you have no drive cabling at all connected to the board & no external devices except keyboard/monitor.
Reconnect the main 20 pin ATX power connector & the square 4 pin (ATX2 / ATX 12V) power connector to the motherboard.
Power the system on again & let me know what happens.
BTW, which model of motherboard do you have? From what I can tell, its probably the L4VXA2 or the L4VXAG if it has the Via P4X400 chipset.
Also, does your P4 support H/T or not?

On the top of the processor you should see a a model number. It will look something like this : SLxxx (where xxx will be a combination of 3 letters or numbers)
While the cpu is out of the socket, check that none of the pins are bent, then replace the cpu & heatsink/fan.
Remove the all the ram & the video card, so that only the processor+heatsink/fan, speaker etc are installed.
Looking through the manual for your motherboard (assuming I've got the right model), I couldn't find any reference to where the speaker connects. Can you please confirm whether your board has a built in buzzer or does it have a speaker connection?
If it does have an external (case) speaker connected, make sure you have connected it correctly.
Power the system on again. Obviously you can't connect the monitor as there's no video card but listen for beeps. There should be a lot of them!
Can you also confirm please -
(1) that your video card is AGP 3.0 & uses 1.5V?
(2) if your motherboard has a jumper next to the ram slots labelled JP2, that this is set to AUTO (pins 1-2 I believe)

I just very recently had a very similar problem with an upgrade to the pc I am working on right now. After installing the new motherboard, cpu and getting all the other components installed I couldnt get my pc to boot up. No beep, no bios, nothing. All the fans came on as well as the hd's, cd roms etc... but it just wouldnt start.
After an attempt to power it up failed, while holding down the power button I powered the cpu off, but on accident i hit the switch again powering it back up, and magicly it booted.
This CPU still has that problem, if I dissconnect it from the power source to make any internal modifications, when i go to plug it back in and boot it up it wont start, so i turn it off via the main power switch and then immediatly turn it back on and it works. I still cant explain it, but it gets the job done.
Now I seriously doubt that this same approach would apply in your case, but if all else fails it probly wont hurt.
And while im at it, if any of you experts could possibly explain why my pc does this, maybe give me a little insight i would appreciate it.

yer, interesting, um............you could try and make sure the motherboard isn't shorted but i'm out of ideas
Thanks for the suggestion Hammm, it's a good one but we've already eliminated that possibility by removing the board from the case completely!
The cpu identifier (SL7KC) is the Pentium 4 3.20E GHz, 800MHz FSB, (Prescott core) with H/T
This is unfortunate because your motherboard only supports Pentium 4's that use 533MHz FSB (max) and have the Northwood core.
In short, I'm not promising that both the motherboard & the cpu are in perfect working order (one or both could well be damaged) but either way, the two are not going to work together because they are incompatible. I suspect that this is reason for your problems! You need to return one or other of the components & get it replaced with a compatible one.

NEW MATSONIC MS9377C+ P4 SOCKET 478 MB LIKE ASUS P4S800
Support High Density Memory, Prescott CPU, 8 USB Ports

*It looks like it will support your cpu
*It has 5 PCI slots & AGP 8x
*It's got an SIS chipset (this is a personal thing but I don't like them)
*Its very limited in terms of upgradeability - it has no sata controllers, only 2 DIMM slots (2GHz max), no dual channel support, no pci-e
* Matsonics online support is extremely limited - driver/bios/manual downloads are available but their knowledge base/FAQ section is virtually non-existent.
It's your call but you should be able to find a better one even if you're on a tight budget.
