doesn't boot up - need 2nd opinion
« on: February 06, 2011, 08:43:14 PM »
My beloved desktop PC at home suddenly gave up. :(  There's a power. Monitor and all fans (processor, video card, chassis) are running. But it doesn't boot up. No response on my monitor. I bought it last 6/17/2009 and is now out of warranty.

I remove one by one to test but doesn't fixed the problem.

1. Try other monitor. - failed
2. I'm using 2 sticks of RAM (1gb & 2gb), tried each one. - failed
3. Remove my video card and tried the on-board video card. - failed
4. Return back my video card. - failed
5. Remove may hard disk then return it. - failed
6. Remove all power connectors then return it. - failed
7. Remove processor then return it. - failed
*** Can't remove the processor from its heat sink
8. Remove all parts, then remove all the dust, then assemble it again. - failed

I do not know exactly the problem, but my suspects are mainboard and processor.
Right now, it has power but cannot boot up. No keyboard lights.  :(

I'm using my laptop now here in office. Any advise before I sent it to the shop this Saturday where I bought it?

Why not?

Have you inspected the motherboard for any burst or leaking capacitors?

    If you mean Carnot because it is stuck to it, then this is most likey the corse, it happend to me and was due to the manufactures not put enougth (forgot name) cooling stuff between chip and heat sink. everything you said that is happening to your PC was also happeng to mine, the only difference is mine was under warranty still ::)

    I think you should change the CMOS (CR2032) battery. It could be dead by now.

    Why not?
    because there's a compound thingy (like a dried grey glue) that binds the two

    yes, so far I haven't seen any damage in capacitors :(

    1. I tried to replace CMOS battery but it still doesn't work.
    2. I tried again to remove the processor from the board. Upon removing the heat sink, the processor also removed - it was stuck-up with heat sink. This time I forcefully removed processor from its heat sink. Then return it back again. -- Successful and my desktop PC boot up in Windows.

    I'm happy now 'cause I didn't bring it to a tech shop -- means no expenses. Hehe. =) Thanks to all who shared their opinions and suggestions. =)

    I hope you cleaned it thoroughly and re-applied Thermal compound....
