New CPU... can't boot up.

[Motiv38]

CPU Intel Core2Duo E7300 @ 2.66ghz
Mobo Dell 0WG864
RAM 1GB PNY DDR2 PC2-5300 + 2X2GB KINGSTON DDR2 PC2-5300
PSU Corsair VX550
Graphics XFX 9800GT

I first got some help here:

for my bottlenecked xfx9800gt.

I confirmed that my Celeron D was definitely the bottleneck, as I tried running CS:S windowed with the Performance tab up on the Windows Task Manager... it was at a constant 100%. So I went out and got an Intel Core2Duo E7300:

Popped out my old Celeron, in went the new processor. Screwed in the heatsink after putting on thermal paste etc. Plugged the power and monitor in, and the following happens:
1) The monitor will stay in sleep mode suggesting the computer isn't POSTing
2) The power supply fan will start and continue
3) The CPU fan will start and continue.
4) The computer will not boot.

The fan that the CPU came in doesn't fit in my case so I left on the old fan as the heatsink and fan connects with the front exhaust.

This is the new fan overtop the removed heatsink... The 4 screws it comes with do not match up to the motherboard. Along with that, the fan wouldn't match up with the front exhaust.

Edit: I'm aware the motherboard + harddrive is unplugged

That looks like a Dimension 5150/E510 case. Is that correct? I'm not 100% certain since I don't have my support manuals handy right now, but I'm fairly sure that the motherboard in that system isn't compatible with the Core 2 Duo/Quad processors.

You might try looking for a BIOS update on the dell support site, some older LGA775 boards won't work with newer CPUs without a BIOS update.

It is a Dimension E520.

My BIOS were updated a week before I bought my CPU. Went from 1.0.2 (I think) to 2.4.0

Blind hope question:
Would installing an older version (like 2.2.1 the urgent one that added CPU support) help any? Or am I just screwed with an incompatible CPU + mobo combo?

Please post your service tag ID# so we can determine whether compatability is the issue.

Edit: Google'ing shows that people are able to use Core2Duo processors on this motherboard... however, they all seem to be 65nm and none 45nm. Can anyone confirm? Is die size the limit on my motherboard?

Edit#2: K, it's all but confirmed that my CPU is incompatible with this motherboard... so now I'm in the market for a case + motherboard
