M7700/D900T every issue raised it's head at once

So I decided to clean clean my D900T today. Took out the 7950GTX and cleaned it and put on new thermal paste, screwed it in and one of the mobo standoff's snapped off. I have it sitting on a jar of carbon glue to keep the picture solid.
Next I cleaned the ram, blew the dust off each stick and socket and reinstalled them, now I'm getting constant BSOD's which were apparently linked to ram since I'm testing each stick individually now and this one works.
I then took out my hardrives and blew them off and then installed a few extra screws I found since I only had 5 holding the 2 drives in place, now I'm getting wierd errors like "this system is not authenticated" then immediate bsod and not booting up normally after that, I think that may be ram issue too though.
I didn't bother to touch the CPU (thank god) although I cleaned the fans next to it but at least they still work.
I need your guy's advice, especially Gophn since he's probably dealt with all these, what's the best way to reattach a standoff, solder or welding. I believe I got the other problems under control, worse comes to worse I have to re-format and/or RMA my ram back to Kingston, thank you lifetime warranty's.
This laptop has been more hastle then it's worth so once I build my new system I'll probly sell it on eBay for $800 ($500 for the card and $300 misc.)

 

You might get $600 for it on eBay.

 

that would be epic. although i did sell one i fixed the screen on for $400.

 

Your right, for some reason I was thinking of the M9750

 

To OP: I have the same problem with the standoff. All you have to do is buy "Loctite Super Glue Professional" (Blue bottle), and do the following:

Optional:
Toothpick
headset magnifying lens, or better. (Don't use magnifying glass in one hand. You need both hands for this project, unless u have very good eyesight)

1: Ground yourself.

2: Get plenty of lighting so you can work better. (Trust me. More lighting, the better.)

3: Figure out which standoff goes in each hole that was in before it was broken off (Do your best on this one.). You can tell it is the right one by looking at the solder joint that was broken off on the motherboard to what the standoff is. If it does not fit well, then switch it. This is important.

4: Once u figure out where the standoff goes where (it feels sturdy). Take off the standoff carefully in the position it was in. Use 1 DROP of super glue on the motherboard, and carefully put the standoff back in. You have about 15 seconds to do this before it dries. Position it well.

5: Add about 1-3 DROPS of glue around the standoff, take a toothpick, and cover the standoff and the motherboard completely. This will form a layer of glue between the standoff and the motherboard, making it stronger.

6: Wait 2 hours. (Trust me. The bottle says 15 minutes, but to fully cure will take 2 hours or more.)

7: ?????????

8: Profit!!!!

WARNING: I'm not responsible for what you do to this laptop. Using super glue is serious business, and if you glue the wrong one, your screwed. This is how I did mine after I broke 2 motherboards with the same problem.

Why the standoff broke?

Based on what I know (I have 11 yrs exp on PC's and 2yrs on motherboard repair), the standoff that is soldered to the board is a poor design. The heat of the video card melts the solder little, by little, including removing, and putting it back; causes stress on the motherboard, and the standoff.

Also, because the solder gets weaker. It also counts as why some people are getting BSOD. The connectors on the video card have small pins, and require constant contact to the motherboard. If there is not enough pressure between the card and the board, then some of the pins are not getting contact as well.

By reinforcing the standoff with super glue, it gives you a second chance to use the board again, and it fights off heat to some degree. Also, the age of the board and oxidation play an important factor to the standoff.

I hope it will serve some use to you, and to everyone that has a similar problem.

 

Thank you D_Smitt for the answer I was actually looking for. I got all the other issues fixed (apparently memory is pickier then I thought) and came up with a redneck fix for the video card. I layered a few pieces of electrical tape on the video card cover and screwed it on, the tape acts as a spacer pressing the card against the board. I also tried JB-Weld twice but to no avail, it would come off with the slightest of force and I waited 24 hours for it to dry each time. Next time I'm at Wal-Mart or other store that would sell that I'll buy it.

 

I just got the glue in the mail today and immediately took my laptop apart to find something rather amazing. The J-B Weld melted and reformed itself on the stand-off and was glued to the motherboard. I reinforced the stand-off and all the others there with the super glue, just in case, and now I'm waiting for it to completely dry, in about 24 hours, before i put the cover back on. I'm going to post this on Instructables with a link to this forum post.

 

You could also buy a used 7700 for spare parts as I did on ebay. Mine is 3 years old and still working good thanks to spare parts. I payed $4500.00 for it when it was new.
