  1. Can anybody help me with this one because i pulling my hair out,I bought a pc from palicomp of which they are not responding to my mails at all,it's a amd dual core 6000+ with 2gb ddr ram 320 sata hard drive with a ecs mobo(geforce6100sm-m in a xblade case 450w power .
    I'm running windows xp with all the updates and security updates but when i go on the net after about 2-15 mins the pc just shuts down dead,then i just hit the power button and it strikes up ok then i go on the net and it's fine for a few mins and then it go's again then i start the thing again and it fine for a bit longer.It only does this when on the net,i've played games for hours no proble,i've done a virus check with avast antivirus with full updates,i've done a system error check with tuneup utilities nothing.

    please can anybody help!!!!!!!!!!

    fair bet to say either your PSU is bad or you are over heating.
    Check out your CPU temps and replace your PSU with a quality one.

    It's time to remove the HSF (CPU heatsink and fan) Clean of the old thermal compound and apply a small amount of new compound. Do you have all the power plugs in the motherboard. Does the dual core AMD's have a 4-post power plug like the Intel's do?

    Is that yellow and black wire bundle near the CPU heatsink connected to the motherboard?

    The Event viewer?....control panel> administrative tools> event viewer> system,..(double clicking) when needed.

    Double click on error then you'll see a microsoft link in the Event property box

    You said your heatsink and fan are on "a little wonkey". Do you mean loose/shakey/not down flat and tight? If so you must reseat that entire assembly to get it to work right. Yes, and you should take a peek @ the condition of the thermal paste on your cpu while you are at it. Good Luck.

    I know it sounds strange but if there was a problem with the processor temp surely it would happen anytime and not just when i'm on the net.?
