My PC Hangs or Re-start frequently

[Rajibchakma]

My PCs config is a Croe 2 Duo 6300 (1.86ghz) Combined with a Asus P5LD2-VM SE Mother board, 2 GB of DDR 2 RAM from Zion, a Asus 6200 TC GPU, 2x250 GB HDD, a Creative Sound Blaster 5.1. The problem with the Machine is that it hangs or re-starts authomatically whenever I run graphic extensive applications like Photoshop CS2 or Avid Liquid, This problem was there since the time I bought the machine 3 months ago. The Vendor says its the GPU over heating, ok, I changed the GPU, still there is no sing of any improvement, I noticed that the GPU temperature doesnot go beyond 68%, mother Board Temperature maximum at 33 to 44% and the CPU 34 to 45, whereas my other PC which has the Pentium D 3.4ghz with Asus P5LD2-VM Mother Board runs hotter twice than the Core 2 Duo with the CPU at 68% in full power still it doesnot behave like that. Where is the problem??? The CPU or Mother Board??? If I remove the Graphic Card the problem still remains.

check your RAM...

Restart in safe mode and see if the problem happens...

I think it is the RAM problem. Remove RAM, clean the slots and insert again. If problem persists, try changing RAM.

It can be other hardware connections also. Once i had the same problem, a few years back. I had sent the PC to my local engineer.

He said the problem was due to a loose connection in the mother board.

Check all the Add Ons to your Mother Board -

Ram
CPU
Lan Cards everything.
