Random shutdowns.....

Hi,
i experience random shutdowns mostly when surfing the internet while watching videos, or when i am downloading files via torrents. After the first shutdown occurs, the PC den shuts down in a few minutes even when not doing anything.... However this doesn't happen if the pc is in idle mode or while i am playing games before the first shutdown... In event viewer i get an error of event id 6008 which doesn't specify anything in general.
my system specs r as follows -

Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 4600+ (2 CPUs), ~2.4GHz
System Manufacturer: MICRO-STAR INTERNATIONAL CO.,LTD
System Model: MS-7501
Memory : 2GB single channel
HDD : 320 GB
PSU : 450 watts
OS : windows 7 sp1 32 bit

formatting the PC didnt solve the problem
checked the temperature of the whole RIG. that was normal.

Regards,
Rodent

Please provide us with your Event Viewer administrative logs by following these steps:

1. Click Start Menu
2. Type eventvwr into Search programs and files (do not hit enter)
3. Right click eventvwr.exe and click Run as administrator
4. Expand Custom Views
5. Click Administrative Events
6. Right click Administrative Events
7. Save all Events in Custom View As...
8. Save them in a folder where you will remember which folder and save as Errors.evtx
9. When asked, save the display information in English.
10. Go to where you saved Errors.evtx
11. Create a new folder by right clicking in a blank area within the folder Errors.evtx is saved in. You could also click New Folder at the top of the directory under the directory path box.
12. Name the new folder Errors.
13. Place Errors.evtx and the LocaleMetaData folder into the new Errors folder.
14. Right click the Errors folder -> send to -> compressed (zipped) folder
15. Upload the .zip file here.

First thing to do in these situations is check hardware:

• If you are overclocking any hardware, please stop.
  
  
• Monitor temperatures during the following tests.
  
  Use the following programs to monitor the temperatures.​
  • Real Temp is a good CPU temperature monitor.
  • Speccy - System Information - Free Download will monitor all hardware temperatures.
  • HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools can be inaccurate for CPU temperatures, but is a good program for GPU temperature monitoring.
  • 
    Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory. Let the memory test run for at least seven passes; the more the better.
    
    
  • Run http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html to determine any hardware problems. Run all three tests for a few hours each. If you get errors, stop the test and post back here.
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
  If you swap any memory components, follow these steps for ESD safety:
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
  Once these steps have been followed, it is safe to remove and replace components within your computer.
