I wonder if you can help me.
I have a Packard Bell UTOW – DV11 which powers up for a few seconds and then turns itself off.
It is acting like the CPU is powering the computer down to protect itself. Though the Chip is stone cold after this brief power up.
I have tried changing the PSU in case it was sending too much power to the chip and it still had the same fault.
I have disconnected the 4 pin power supply to the CPU and the computer will then stay powered up indicating to me there is something going on in the CPU area.
I have powered up with only the MB connected and still faulty.
I have cleaned the heat sink and fan.
The paste on the heat sink is good.
The power button is not stuck.
The spec is: -
* Intel® Core 2 Quad Q8200 processor
* 2.33GHz, 1333MHz FSB, 4MB Cache
* Genuine Windows Vista® Home Premium
* 4GB DDR2 667MHz memory
* 640GB SATA hard drive (7200rpm)
* NVIDIA® GeForce® 7100 onboard graphics
* Dual Layer DVD Rewriter
* 18-in-1 media card reader
* 6x USB ports (2x front, 4x rear)
The unit has an MCP73PVT-PM Motherboard.
I have been advised it is the MB that is at fault, but would like a second opinion, as a MB fix is expensive. The like for like is about £100 and I can not seem to find a suitable generic replacement. If you know where I can find a replacement Motherboard or better still if you know what is going on please tell me.
I appreciate your time to read this.
