AlienWare Aurora wont boot
I did some windows 7 home basic edition updates and it was done so it turned off.
I went to start it but it started to post, shut down and then restarted but did not post.
Nothing seen on monitor but fans turn on and lights come on.
I removed the MB battery for 5 minutes, removed all RAM and video card.
No beeps. I left it over night and it did beep twice but ended in the same condition.
Monitor works fine, I know one of the RAM sticks has an issue, video card is properly
seated. Any help would be good before this all goes in the trash. Thanks!

You don't say what model.
Here is a doc I made a while back.
-------------------------------------
Computer starts up fine sometimes, but sometimes not
---------------------------------------------------
- Maybe it won't start at all or stops before complete BIOS posting
This list is about core hardware & power problems.
- "Windows won't start" is not covered here. You must be booting to a bootable environment. Remember F8 for Windows SafeMode.
If you changed something, but it back the way it was.
- Must verify motherboard, PS and machine still works.
Remove anything non-essential (USB, extra slot cards & drives, etc.)
- One dedicated (known good) video card in main slot
- Maybe even install a lower-power but known-good video card.
Remove and re-attach all connectors, DIMMs, etc.
No CPU, MB, or GPU OverClocks should be activated. All stock speeds.
Be sure entire cooling system is working.
Check Power switch with Ohm-Meter or install temporary one.
Verify Power Supply wattage (large sticker).
If Power Supply has "Test Button" on back, make sure it tests good every time (like 10 in a row)
Test Power Supply with $25 digital Power Supply Tester
- Voltages and also "P.G." value between 100ms and 800ms
Try another known-good Power Supply (of equal or larger amperage)
As a last resort, you can try re-seating CPU but LGA and/or CPU failures is very rare.
- If you get this far and system still won't POST, you might have a MotherBoard failure.
Use good UPS (like APC), but also try directly into wall (at least once).
- Better to use UPS ... just make sure you are not having a "lack of pure sine-wave" problem
If not using a good UPS that stabilizes & monitors AC-power and quality, you should:
- Be sure wall AC Power is good and proper (by testing it).
- Be sure other high-amp machines (other desktops, TVs, AVRs, etc) work on this "leg" of the AC power
- Test machine on the other "120v leg" or another building.
