Computer wont turn on after upgrade

I upgraded my t8100 processor to a t9800 and now my computer will not turn on. I have a d9843cl laptop with a p473 socket. After I installed my processor and put everything back together and I plugged my computer in it lit up. When I go to turn it on my computer lights up, the fan starts to spin and I can hear my optical drive turn on. My screen remains blank this entire time. after about 5 seconds or so my computer restarts and freezes. If my computer is just running of battery power my computer starts to turn on then just turns off.

I thought this might be a voltage issue but the processors are meant to run off the same voltage. I would really appreciate any help you can give me.

 

Did you update the BIOS prior to upgrade? If you haven't, put the original cpu and update the BIOS and try, check for any loose connections as well.

 

My laptop isnt officially supported for windows 7 on HP's web site. I have a dual boot system of windows 7 professional 64 bit and windows xp 32 bit and it worked perfectly. I never had to update my bios for this dual boot system. HP only offers Bios compatable with windows vista 64 bit for my laptop. Were would I find it?

 

That depends on who manufactured it. Usually, there is a site dedicated to just your model in question along with all the bioses, drivers, and anything else needed for you laptop to run properly.

 

It looks like you didn't applied the thermal paste properly. It seems to react like an overheated cpu would do

 

That is very strange because I applied thermal paste to the CPU and the chip next to the cpu

Is there a proper and improper way to do it?

 

Of course you'd need to check on the BIOS for a processor upgrade. You can probably use the Vista updater from within 7 without much issue. I imagine the laptop was sold with Vista and no other OS, so you're not seeing tools for other OSes.

There absolutely are proper and improper ways to apply thermal paste. You're going to have to do it at least twice to install the latest BIOS and then put the new chip back in, so you'll get some practice.
There are an abundance of threads on this board, other boards, and the internet at large on how to apply thermal paste, so search and read up.

 

the gpu usually need lot of thermal paste but the cpu not

a single dot in the middle of the chip is usually enough
I usually use a credit card or a prepaid phone card to spread it in order to make it as flat as possible
to know if the heatsink is well in contact with the cpu after reinstalling the heatsink, the heatsink should not move when you push it

 

What? No. It's not a question of quantity at all. It's a question of thickness and gap-filling. More is not better. More paste --> less heat transfer.

What?

 

I appreciate the quick replies guys.

If memory serves me right, I already had the F59A bios update installed on my system so I dont think that is the issue. I think I am going to have to take my computer apart, scrape off all the thermal compound and re-apply it correctly. I will also check, double check, and triple check that all connections and screws are in the right spot.

 

I know about the heat transfer and the thickness but what is more important a burnt gpu or a slightly overheating gpu

And I know it will move a little bit because the thermal paste is half liquid half solid but as it's not supposed to have a lot of it, it should be barely noticeable for the cpu

If you have another way to do that that's fine for me, share we are here for that

In fact there are probably as much ways than there are computer on earth
(if your cpu has 1, 2, 4 cores, if you are left handed or right handed, if you have big fingers, if you have parkinson, if your grandma want to use your computer right away etc...)

 

Please keep posting your ideas and suggestions. I will post back with updates as to how my laptop is doing

 

the answers quite simple.. u have a 965 series chipset which can't take 1066MHz FSB processors like T9800 even if u have same socket. .. T9500 is max u can go. return the T9800 and get something else.. thread closed..

 

I though about this but in this case the cpu is not supposed to down speed?
Ok I didn't read well. I get it

 

I can't believe I overlooked that... Oh well you live and learn I guess
