Acer Aspire 6920G restarting

Hi..
Just to get some idea,advice
Own this 6920g almost 4 years..
Already make the biggest hardware upgrade..
CPU : T8300 to T9500
GPU : GS9500 to GT240M
(Already post in others thread about my upgrade)
Suddenly, after a month the laptop keep starting..
Expected the heat of CPU and gpu,so replacing with new thermal paste with copper shim but still restarting...
Because the laptop keep restarting make hard disk cannot boot and BSOD appeared.
Need to chkdsk on other laptop..

Can boot but restarting again and again...
The hard disk produce some overheat..
Try to boot with xp live CD...cannot detect HDD and laptop running longer, not restarting..

So, I excpeted the problem maybe come from HDD.
Any suggestion..?
Hope somebody can give some idea.
Thanks..

 

Does BIOS even detect the HDD?

 

when booting to bios,detectable..
boot until win vista appear for 2,3 minute..
then restarting again..
try boot with win xp live cd,hdd no detectable..
before this,using win xp live cd,i can recover my data fm c: before restoring to factory.
i expected maybe my hdd need to be replaced with new.

It's not the HDD looking at SMART attributes although I wouldn't put much trust in this drive in months to come.
All attributes look good but it's been working for over 18K hours

It may be a motherboard or HDD connector problem- the former would be expensive.

 

so..no solution..??
i'm doubt about mobo because it running with live cd succesful...keep runninng for 3,4 hrs..
when try to boot with hdd,installing/restore win..it will restaring in middle way..

btw,i will try booting my hdd fm ext usb..
myb hdd connector cause all the problem..

any result will inform u back.
anyway,thanks for the advice..

already boot with ext hdd.
however it still starting..
so,i try to boot windows installation dvd only,without hdd.
boot until windows appear...it restarting again..
i try couple of time..still the same problem.
so,myb the heat...???
i didn't do any overclocking on the hardware after upgrade the cpu ang gpu.
or need to put back the origin cpu and gpu 1st..??

what u mean the former would be expensive..??

I meant that a motherboard issue would be expensive as it would require a new mobo.

 

so..the problem myb mobo..??
but i still can boot with live cd.
the moment i boot with installation cd,thee problem occur.
before this,sometimes the laptop boot normally..
after i restart for finishing the win update or anything else,the laptop will restarting several time until it boot normally.
only 2,3 weeks ago the laptop cannot boot normally.
already invest for huge upgrade i made.

Do you still have the old parts (CPU and GPU)?

Could you test if it happens with those old parts installed too?

Just to be sure.

 

still have it.
will try it.
tq.

today try to replace with original cpu and gpu.
during removing the heatsink for cpu,gpu and mobo chipset..found that the heatsink didn't touch with mobo chipset.
so,replace the heatsink properly w/out changing the cpu,gpu.
try booting with ubuntu.
before,booting fail.
now,booting successful until ubuntu desktop.
but,the ubuntu only running about 2,3 min.


so,myb because of the heat of the mobo chipset that cause this problem..??
afraid the chipset will broken because of this problem..

any idea,advice or solution..??
