I have toshiba satellite l645 I was going to bed and I put it into hibernation mode like I always do then the next day I get home I go to turn it on and it turns on but the screen stayed black. The power...

There are some problems which may cause that:
1. Memory defect.
2. South bridge defect.
3. Bios Defect.

Try this one to find out which one is your problem:
1. Remove your battery and plug the external monitor via VGA or HDMI port and turn your laptop on with the AC cord attached to the outlet. When you can see its welcome screen via external monitor then it has a problem in its LVDS driver. But when you see nothing then try the second step.
2. Unplug the Cmos battery located under the palm rest on the left side of the touch pad, wait for about 2 minutes and then you can try to turn it on. When nothing appears on the screen then the problems may cause by your south bridge defect. To know this problem just touch your south bridge while it is turned off, when it is warm then your south bridge is working but something wrong with its pin. When it is cold then your south bridge has a problem in it.

When you see the two above step yield nothing then better for you to bring it to a service centre.

Good luck

Dell XPS 600 just dies. Power shuts off with no messages.

This could be one of Three different things:

1) Your PC is overheating. Clean out the dust around the processor fan and intake vents. Make sure that your fan is working. Make sure that the North and South Bridge chips are not overheating either (the two other large chips on the motherboard)

2) Your Motherboard has defective Capacitors. Once your Capacitors start bulging or leaking, the board will need to be replaced.

3) Your Power supply is failing. Not dead yet, but enough of a pause in power distribution to cause the entire system to go down. Power supply can be replaced as well.

The south chipset bridge of my Asus k8n-vm motherbard heats up

85 to 95 is ok. Anything higher than100 is pushing it. If possible add a fan to the side of the system case (Best choice) or you can buy a south bridge fan. You're MB doesn't have holes in the MB to attach a chipset fan but you can still attach a cooler on to the chipset. Like this fan;
And you'll need this as well for a good bond;
