Solved Help With Gateway SX855-UB10P desktop Mobo (PART 1)

June 6, 2014 at 19:45:41
Specs: Windows 7
Hello my first post here and hoping I can get some help. I had this computer as a backup for my laptop that I was having problems with. I understood that I could upgrade the processor to an i3 max 65 watts gen 2. Well got one one sale from Micro Center and my friend and myself though easy project well we popped it in and it spun up and then turned off, so we replaced the old processor and everything was fine.

Did some more research and called Gateway and they said that we need to upgrade the fan. We we got a new fan but found it wouldn't fit so we tried the old fan again someone else said it was fine started it up and same thing. So we once again replaced the old processor and now that doesn't work. This was a small business machine for me that's why I wanted to upgrade the processor so thinking it was the motherboard I bought a new Gigabyte Micro ATX when I got it I found that it didn't fit so I'm just going to buy a small new case and try to build basically a new machine, but if I could get the gateway working again I wanted to donate it to a local high school, so I was hoping someone might have any thoughts as to what could have possibly happen maybe it can still be salvaged and some poor kid could still get some use out of it. Thanks for your support and time!!

✔ Best Answer
I tried googling the model number you posted but came up empty (except for this post), could the model be SX2855-UB10P? The motherboard is most likely an Acer H61H2-AD.

Regardless, provided you unplugged the power cord & took the necessary precautions against ESD (electo-static discharge) when working within the case, my guess would be the problem has to do with the thermal paste between the CPU & heatsink. If you didn't use any, used too much, or reused the old, it can prevent the system from firing up. It's a shame you didn't find this site 1st because one of us could have talked you thru the CPU swap (or advised against it) & saved you some money.

Please explain in detail how you went about the swap & include the method used for applying thermal paste. The 2nd Gen i3 requires the vertical line method:

Thanks and you are sooooo right just wish I had of found you guys sooner to!! Well I had planed to make a donation to that high school anyway, and I believe you are right when I Googled I came up with the same board made by Acer, well I can't thank you enough for your help, let me try what you suggested and remove the past and reply.

Someone also said that maybe the bios should have been upgraded first before installing the i3, but I'm totally lost as to why when we replaced the old processor it fired up for a few seconds and then just died. Both processors do look a little messy with the thermo paste So I will definitely be trying what you suggested.This older Acer motherboard should accept this processor I call Gateway and read a few posts before I even considered it, PLEASE see the link below this is how I originally found you, and this guy was basically trying to do the same thing. Please check back still need you continued help. Thanks!!!!

Hi again Riider!! I'm now convinced that's the problem after looking at your link, just one other question. How do we remove the old past what should we use or what method should we use before we reapply. Thanks!!!!

Use a high quality rubbing alcohol (95%+ isopropel) on the surfaces, use an old plastic credit card as a scraper to help with the removal. Do NOT use any metal for a scraper or even microscopic scratches will make the thermal contact worse. Remove the CPU from the socket before starting and handle it by the edges.

You have to be a little bit crazy to keep you from going insane.

Too much paste will not damage anything. It will just make a mess & prevent the system from booting, plus it's difficult to clean up. Everything you need to know about removing the old paste & applying the new is in the 2nd link in response #1. If you don't want to use Arctic Silver, the cheap "heat sink grease" from Radio Shack will work just as well.

Thanks Rilder!!!!! can't BEGIN to thank you and the others for all the help, hay I found this stuff. Its made specifically to clean cup and I also found a non conductive thermo past, I read that that the conductive type and possibly damage the CPU or Motherboard if it gets into the wrong areas and I Just can't afford anymore screw ups on my part. Please see below. Thanks!!!!!
