Lan Boot Issue

Specs: Windows 7 64-bit, i7 920/6gb dominator gt 1600
My computer sometimes gives me a long beep
and 3 short, if I move the ethernet to the other
connector on the mobo, it loads but it doesnt
load some startup programs. After a reboot
everything is 100%. 3-4month old rig, ive been
using it for alot of downloading overnight
recently (not p2p) if it matters at all.

"2x300gb velociraptors in raid0"

Nothing to do with your problem but what do you accomplish with a raid0 setup? You do realize that if you have a harddrive crash in a raid0 configuration you lose ALL your data.

I fail to understand why anyone with a large drive, over say 120gb would not partition it to have windows on it's own in say 60gb with the rest as either a single extended partition or multiple partitions for progs, data, music, movies etc

Why would anyone want a single 600gb partition? Defragging such a monster would take hours.

As for your actual problem, It is unlikely the beeps relate to the LAN port. They are more likely to relate to ram or graphics and to find out what they mean, determine what version of bios you have and then visit http://www.bioscentral.com/

As for the raid I keep partition images as backups so I won't
be losing much when the setup has issues. My case only has
2 hd bays and I wanted a little extra speed. I'll be changing
the case and switch to raid5 in good time.

The beeps refer to ram after 64k, but my ram is fine. I ran
memtest+ for 10 hours a few times without any errors. The
computer doesn't load and keeps beeping unless I remove the
ethernet. This happens everytime it has trouble booting. I
understand it shouldn't be related, but it is. I have tried
everything I can think of, and moving the ethernet is the only
thing that works everytime.

It seems that your LAN port, when something is connected before bootup, is somehow interfering with the voltage supplied to the ram slots.
I know very little about the circuit architecture of motherboards but I know a typical powersupply produces voltages @ +3.3, +5, +12, -12 and in older systems a -5V as well,

Now since the ram normally does not run at any of those voltages there must be some kind of voltage regulator on the motherboard that steps down the volts to the ram slots.

I would be looking in bios to see if there is any available adjustment you can make to ram voltage. If it is set at say 1.5V then up it to say 1.6 and see if it is more stable at that.

I presume the LAN port you are using is onboard rather than a PCI NIC. As a last resort if you have a PCI slot vacant would be to instal a separate network card and see if that alters the bootup issue.

Another possibility is a weak powersupply. Is OK once the system is booted but the extra load at startup when the LAN port is active, is enough to cause the glitch. If neither of these is the case then motherboard replacement becomes a more likely prospect. Good luck with it.

The lan has nothing to do with your system failing. Your system is unstable from either a hardware or software or both issue.

Use diag suite to see if hardware.

Most motherboards with two network controllers have one at 100MB and then a 1Gb. Is that where you are connecting to or from?

Look at your manual and also try booting without the LAN connection at all.
