Computer freezes

Hi Team,

I have FX 8 core AMD processor , mb support 32 RAM, at the moment i have 16GB RAM on it... Initially after the computer is started CPU goes 100% and then when i start my VM's , GNS3 applications it works fine with 8 to 10 % of CPU utilisation also less memory utilisation...

But for some reason when i try to run some exe file, start the browser for internet or without any activity ( No VM's or No GNS3 running { High processor. memory consuming apps ) the screen stops responding , no activity...Please help me on this subject,.. how to fix this.. as i am planning to get ESX server on this machine at the moment i have windows 7... not sure if the heat sink is an issue/Heating is an issue,.... Processor looks very cool or cabinet itself is cool not heating up..........................

If heating/sink an issue how do i fix it... ? help..... :)

Hello Nobus,

Looks like it happens intermittently, I have rebooted it only happens when i turn off the screen and leave for any kind of Download and such. And when i try to switch On the screen my CPU makes sounds as if it has to do some huge task ...... And its kind of Annoying i suspect the something to do with Graphic PU/No Signal to Screen... but now it happens very rare...

At the service center they tested with a different PS and it worked .. so my initial issue is fixed Tower never gets hanged now.... But its the Screen now.... ...

Any Help appreciated.

ok let me put it again.

#1 No activity on screen / Mouse or Keyboard screen activity hangs stops responding
#2 No display / Monitor going in Save mode ( When left without any activity or input from keyboard or Mouse for certain period for downloads to complete or left by itself....

Issue #1 looks like it got fixed after PS was changed to Cooler Master "Thunder".
Issue #2 Appeared only after the Issue #1 was fixed my suspect even if Issue #2 was existing it never got a chance to show itself since issue #1 was always on top of everything.

So when i say CPU makes sound, its the sound from CPU tower ( Whatever we call that rectangular box), It makes lot of sound when the Video signal to monitor goes in "Monitor in Safe mode " & Then next message i see will be " no Signal from CPU or something like "

Note : I run resource consuming Apps on the System there will be no sound.. ** It only appears when the system is in Issue #2.. So i suspect Mother board could be an issue...

Thanks
Irfan
