G73-JH A1 repaste problems

Some backstory first, scroll down a bit to read my problem...

Alright, so after months of ambient temperatures ranging from 65-70C, I decided to try repasting the GPU. I had tried using compressed air to clean the vents, using a notebook cooler, and turning my house's thermostat down.

My ambient temperature was about 66F, or about 18-19C, and my idle temps were still around 62-65C. When playing games, the fans would get really loud and the temps would soar up to 98C+.. occasionally getting over 105.

I read pretty much every repaste thread here and determined that I was capable of doing it myself. I have repaired electronics before and didn't think I'd have a problem. Well I didn't. Got that nasty speaker cable and keyboard up with no issues at all. Cleaned off the old paste with this:

Newegg.com - Arctic Silver ACN-60ML (2-PC-SET) Thermal material Remover & Surface Purifier - Thermal Compound / Grease

...and some coffee filters, and then repasted with a 5mm ball with IC Diamond 7.

Beginning of Problem...

I put everything back together, and the laptop booted fine. The screen flickered twice, but nothing major. Upon entering the GPU clock tool, I immediately noticed the default clocks were lower than they should be. 160MHz core clock and 700MHz memory clock. Huh. I opened GPU-Z and it indeed detected Ati Mobility 5800 series.. but the clocks were lowered for some reason. Odd but I set the clocks at 700/1000 and checked my ambient temperatures.. which hovered around 45-50C. Very nice. I played Guild Wars at max settings and resolution for a bit, and the temps got up to 62C, but no higher. Very nice.

So I turned off the laptop, took it upstairs, plugged it into the AC adapter and pressed the power button. Black screen. Nothing was displaying at all. No led backlighting on the sides either.

I took it back downstairs and tried the power button again, and it turned on, I opened the Bios and checked the vBios version and it said something like, 000.000.000.343.Not ..or something like that. Well that's not good.

I hit the power button again and it turned off.. then turned itself on by itself. It turned itself off and on several times and finally booted normally! The screen came on, everything appeared to work fine, clocks were at normal 700/1000. Then after 10 minutes or so.. the screen started to flicker black, more and more until it was completely black.

Now every time I turn it on, there's just a black screen, the LED backlighting isn't turning on either. Just blackness. I also can't boot the Bios anymore. I tried plugging it into an external monitor, but nothing displayed.

If anyone could help me with this, or let me know if I'm still under warranty and should contact ASUS or perhaps try something else. Please help me out!

 

Dump it in the trash can and buy new one?

All the headaches and stress I bet you've been gone through are not worth it.

 

Not an option I'm afraid. Buying a new one, that is. Don't have the money.

 

A repaste shouldn't void your warranty as long as you didn't damage anything while disassembling and reassembling. you should still be able to RMA it.

 

Well there's this yellow plastic-wrap stuff that surrounds the GPU, and as I was cleaning some of the liquid spilled under there. I removed the tape, cleaned and dried it and put it back on. I hope that's not a warranty seal. Haha..

Could that liquid have shorted out the GPU? I hadn't realized that it was wet under there the first time I booted it.

 

the liquid shouldn't cause any problems if it spills on electronics, i've had that happen to me several times and everything was fine...

gotta be another problem somewhere, try RMA
