p7805u CPU AND GPU overheating

ive had my p7805u for about 1 year now 6 months after i bought it it was overheating for no apparent reason i opened it up checked everything cleaned out dust still was overheating i put in some ic diamond still over heating so then one day i was mad taking it apart and i accidently broke off some of the screws to the motherboard heatsink yikes so then u guessed it the computer just started getting hotter and hotter i left it like that been holding it down with pencil sticks and it stays within safe range 79c-82c i was gonna get it fixed but no money and i dont want to send to gateway because they will just make me get a whole new motherboard thats my first problem...yesterday i was playing a game normally all of a sudden i start hearing my gpu fan it sounded like if it was hitting on something so i turn off the computer take it apart nothing there just some dust take that out turn it on and now it turns on but barely has power dosent keep my gpu temp down at all was playing crysis my temp raised to 111c on my gpu so im not playing any games i need someones help to tell me what i should do with this laptop i know for the gpu im pretty sure i need a new fan as for the cpu can anybody please tell me where i can take it to get the thing were the screws go to be soldered back into the motherboard so my heatsink is touching properly with my processor.


also even if i do get that fixed before i ever took it apart it was overheating it had no viruses nothing could there be something wrong with my processor that causes it to overheat because before i broke those things it still was overheating and it had icd7 so it has to be something else

 

Sounds like you shouldn't have been working inside of your laptop to begin with.
If you broke the screws off for the CPU your best bet is to use a center punch, drill them with a SMALL drill bit, then easy out them.

From your descriptions of your past screw ups, I'd urge you strongly to pay someone capable to do this..

This is much harder than removing a few screws and replacing them.

 

i dint break the screws i broke the thing that the screws goes in..what holds the screw its a little gray thing 4 of them are broken

 

is there any place i could go for this that u would go?? i was told i needed the gray things to be soldered back into the motherboard so that i can tighten the screws but when i get that fixed im also gonna order a new heatsink and all that to put everything new there

 

A picture is worth 1000 words....

 

il take one today off how it looks and il upload

 

Ditto!!! But just to ask, how in the world did you break them? I changed my CPU on my old 7805 and it seems the same on any comp., you would have to really torque down to break those tabs. Jus' sayin'!

 

like i said i was mad at the time not so experienced as i am now with it and i guess the screw was still on there and not completely loose and i pulled the heatsink and the things just came off with it

 

$125 on ebay to get it repaired.

there are the pictures dont laugh to hard guys

 

where can i get a cheap gpu fan for my laptop since its dead?

 

I guess the moral of the story is NEVER work on delicate electronic equipment when you're inexperienced AND pissed-off!!

I know that doesn't help you now, but all I can say is good-luck fixing it!

^^^^^^Hahahahahahahaha! Yes. Now, as for the screw issue, you could fix that with some longer screws and some nuts with some plastic washers. Did it with an XBox 360 about a year ago. Just have to tear it ALL the way down to just the mobo. As for the fan-not sure. May want to contact Gateway. Might not be too expensive. Of course keep an eye on eBay too. Need a better explaination on the screws, just let me know.

 

yes please explain the screws thing im gonna have a friends dad do it as im never touching my computer again lol

 

Why not? It's not like you're gonna break it! Something like this- Here. You'll just have to determine what size screws and MAKE SURE no metal to metal contact happens, which is where the plastic washers come in. Maybe even some rigid plastic tubing. Break off the old pieces completely and use the smallest diameter screws possible that you can work with. May have to glue the screws to the mobo cause I don't know how you're gonna get it back together if you put the heat sink on before reassembling.
Did you check the link that Ultimate Destruction posted? Might be the best and easiest in your case.

 

What the??!? KC, fixing the posts is incredibly easy. What happened to your 7805 happened to mine a few months ago. Overheating, combined with probably some bad solder joints, caused one of the GPU mounting posts to break off of my mainboard too.

Where abouts are you from? If you're in the MA/RI/NH/ME area and you still have the original mounting posts, let me know and I can fix it for you for the cost of a six pack (as in, you buy me a six pack of beer and I'll fix it for you).

If you want to try fixing the mounting posts yourself, you'll need the following:

- A BUTANE powered soldering iron (Radio Shack sells a Weller and their own branded one that'll do the trick). You don't want to use an electric one for two reasons:

1) An electric one can induce a current into the motherboard and can damage sensitive parts. In this case you'd have a better chance of hitting the lottery than it damaging the board since you're working on a grounding point, but it's better to be cautious than cause more damage.

2) A butane powered soldering iron can get hot enough to do the job correctly. A 15 watt iron isn't hot enough to do the job properly.

- Silver bearing solder (again, available from Radio Shack)
- A small bottle of butane (most convenience stores carry this).
- Gel super glue
- Pair of tweezers

First things first: Put the broken mounting post(s) back onto the motherboard back in the original holes they came from. Unless you do that they won't align properly, making the post sit at an angle (unless you prep the posts and holes by removing the old solder first). Once you know you got the posts back in the right holes, you can apply a SMALL amount of super glue to the bottom so they stay put while you solder them (let it dry for a few minutes). Notice I said a SMALL amount of super glue...

Here's the thing.. If you don't know what you're doing here, OMIT the superglue step and work on the posts one by one. Cyanoacetate (aka superglue) contains cyanide. If you only use a little bit at the very bottom of the post you'll be fine. If you use so much that it starts oozing out of the sides it'll probably burn once you touch the soldering iron to the parts, releasing the toxins into the air. The dose would probably be lower than what you'd get from eating a bag of Blue Diamond Almonds, but if you seriously have no idea how to properly apply the glue you're better off NOT using it.

Heat up the soldering iron. If you're using the radio shack branded butane soldering iron, set the fuel lever to about 1/3 of the way up from off. You won't want the tip so hot that it damages the surrounding electronics.

Put the tip of the soldering iron at the base of the mounting post and flow a little bit of the solder around the base (using the silver bearing solder). If you can't touch the base of the mounting post without touching one of the surrounding components, you can touch the top of the post with the soldering iron and gently press down. Be careful if you do that though since it'll take more heat to get the joint hot enough to melt the solder. Don't gob it on, if it isn't flowing easily then the joint isn't hot enough. It'll only take about five seconds of applying heat from the iron to flow the solder around the post. If the post starts lifting off while doing this, use the tweezers to hold it down while quickly reheating the base of the post again.

Repeat for any other broken posts.

In all, it'll take you about five minutes total to fix all four posts if you need to fix that many (not including system tear down and reassemble time).

If you don't feel like you're up to resoldering the posts and the post broke cleanly off (so there's a clear hole through the board where the post was), there is an alternative method that I've used on video cards that works great.

Go to Home Depot, Lowes, etc, and look in their hardware aisle for NYLON based screws and nuts. Pick up some fiber washers too. For each post you'll need one nylon screw, two nylon nuts, and two or three fiber washers.

Put one of the washers on the screw so it sits against the head of the screw. Thread the screw through the BACK of the board, place another fiber washer on the screw (so it sits against the top of the motherboard), thread a nylon nut onto the screw and gently tighten it so that it's now attached to the board. Put the heatsink back on and then use another nylon nut to attach the screw to the heatsink's mounting bracket. Trim any excess length of the screw with a pair of diagonal cutters (leave a little bit above the nylon nut at the top so it doesn't slip off). Done.

 

MA/RI/NH/ME dont know where that is seriously lol i live in puerto rico in florida at the momment for vacation

 

Great instructions and idea, but really, sounds like he IS NOT the one to be doing this. Lol!!! I wasn't sure if the mounts were soldered or plastic. Your solution is easier for sure.

Massachusetts, Rhode Island, New Hampshire, Maine all in Northeastern US. Just to let you know I messaged the guy on eBay with the link provided by Ultimate and he said that should be included in price. Save yourself the headache and send it off. Or try what Digidoc said and if you can't get it, then send it off.

 

found the somewhere to buy the gpu fan but its 70$!!! Laptop Parts for GATEWAY | P-78 series (P-7801u FX, P-7805u FX, P-7807u FX, P-7808u, P-7811 FX) cooling fan (sits on left side of motherboard, Sunon GB0507PGV1-A, 1.6w (Over 10,000 notebook parts) is it worth it or should i wait for ebay could anybody find something cheaper i dont even have 125 to send it out atm so i dont have the 70 to get the gpu fan fixed aahhhh

 

$70 is a rip. Won't the repair people on ebay include the fan in the $125?

 

i dont know would need to ask

 

Have you seen THIS?
. Look Here too. And maybe one will work.

 

That fan is used in a few laptops. Here's a few places that sell it, some as low as $10 shipped:

Sunon GB0507PGV1-A - Google Product Search

 

Forgot to mention earlier, if you don't feel comfortable soldering the posts back on, you could use some JB-Weld. The stuff is strong enough that its used to repair engine blocks, and it can be machined afterwards too. Just make sure that you:

a) LET IT DRY OVERNIGHT, PREFERABLY 48 HOURS CURE TIME.

and b) not as critical, but you should consider running a small grounding wire from one of the pegs of the heatsink to a good ground point. Epoxy can be capacitive. The chances of it developing a static charge are small, but it never hurts to be safe.

 

What's the status of this? Did you get the fan and/or send the laptop off for repair yet KC?

 

Wonder if I can send it with a QX9300 in it and tell them my P7808 won't boot anymore...............

 

Ha!!!!!!!!!! Still waiting to get that Quad working huh, Tanware? Check my sig. Had to leave the 7805. Loved it, but dying for a Quad.

 

Yeah, still grunging for a quad. Thing is I don't even generally stress out the P9600 but I do have the "I Wants". My P7805 just runs too good.

It runs cool, never crashs, more than ample power and 1920x1200. With the SSD all I have left is the CPU now to go after. That is besides eventually 8GB ram. I bnever seven se 2GB used so that is a non issue for now. Rarely though I'll see 100% cpu spikes like when editing photo's etc. So CPU is my next thing.

 

I loved mine. LOVED it!!!! Hated to let it go, but with the newer games, it ws starting to get worked. Not the P9600, but the GPU. Think I got it covered for a while now. Still got my money out of it. And, just so you all know, the 7805 is Waaaaaaaay more portable and a heck of a lot lighter than this M17x. But I still like what I have. Good luck with the quad, but don't think it's gonna happen.

 

I'm pretty sure it never will happen. I am not a gamer so there is still quite a bit of life left in this. Bad thing about gaming machines that it is almost a yearly update thing.

I am pretty sure I'll go with a x9100 soon. Again not that I need it but have the power available on tap when I eventually do.

 

sadly no i still have not got this laptop fixed just using it lightly till i have the money for a repair

 

Sometimes repair is the only real option................

 

ordered the gpu fan today and while i was at it a new power adapter and heatsink waiting for that to arrive to take it to a friend of my uncles that will fix the motherboard issue then i will be set also ordered a 320gb 7200rpm to put it in raid 0 next thing is the processor after i get the heating issue fixed i really love this laptop not letting it die

 

If I were you I would either get a 500GB 7200rpm drive or an SSD for performance because from what I've seen RAID 0 sucks.

 

That's quite a bold statement to make without any evidence. Where have you seen that? I'm running RAID 0 on my P-7811FX without any issues and a noticeable improvement in performance.

 

It doesn't suck there are just way better options. Primary SSD and secondary storage being the main one................

 

Yes the SSD would really be optimal solution, however, for me the RAID-0 has been a good option since I already had 2 HDDs available and didn't have the $$$ to spend on the SSD upgrade. Might consider changing to SSD next, though..
