    Hi

    I am trying to upgrade my aspire 5520 cpu from Turion TL-56 to Turion TL-60. I have updated laptop's BIOS to the latest version (v.1.33). However, when the new cpu is present, the laptop does not boot. The power light goes on, the cpu fan goes on, but after a second the laptop switches off, switches on and does the same thing all over again. The screen stays blank.

    I tried taking out both RAM modules and booting, the same thing happens - nothing shows up on screen and the laptop keeps on looping between switching on and off.

    Is this a BIOS issue? Or is the new cpu just dead?

    Any advice will do :)

    Thanks!

    Edit - I also tried resetting CMOS by taking out battery and holding the power on button for 45sec, not sure if it worked, though.

    It seems that your new cpu might gets overheated...
    After few loops, touch the heat sink and cpu and check if there is a hude difference in their temp...
    As you can see in my signature it should work without problems...

    Cheers

    Okay, I will try to check that. I did use thermal paste, though - the heat should be transferred to the heat sink. What else could cause overheating?

    Out of interest - what BIOS version do you have?
