Computer help asap
 

Just put my old mobo (which worked) into my kids computer, re-installing Vista and the computer keeps shutting off before I can get anywhere into the installation of Vista.

Help??

power supply?

Sounds like overheating, check the CPU heatsink. Clean off any thermal compound and re-apply, then make sure the heatsink is sat correctly and firmly attached to the CPU.

The computer was working fine with another mobo, I am actually thinking it maybe the mobo, as when it was in my computer, it would struggle to boot sometimes, in the morning, once it started to boot windows. It will sit on the BIOS screen for ages, but as soon as you start to install and use the IDE hard drive, it would shut down.

Tried a BIOS reset? Take the battery out for about 30 minutes and try again.

Easiest way to see where the problem lies is to unplug stuff one at a time, until the BIOS boots normally. This is probably what is causing the problem. In my experience, slow BIOS is normally the clock needs resetting, or dome IDE jumper setting (check you dont have multiple masters etc).
:woot:

Yeah, tried that, and with two items on the one IDE channel, really slow to post, one item (either hard drive or dvd) and is fine, soon as you start loading up the ide port, it shuts down.

Are you using cable select on the Ide channel? If so, turn it off, make the HDD the Primary master, and dvd/whatever else, the slave.
Apart from getting a new Ide cable, not too sure what else it could be...

Tried three IDE cables, even bought a SATA DVD drive, as soon as it loads up, poof, shut down, HD is set to Pri Master to.

Are you trying to install windows from a cd in the dvd drive at all?
Might be the dvd is pulling too much power, had this problem at work.
Try another power supply?
:)

tis a 500W supply, no fancy graphics, only a hd and dvd, so power draw isn't much, it allows it to spool up, but cuts when it starts to load the IDE, with an IDE DVD it barely got past the POST screen grrrr think I have convinced myself it it the mobo.

new mobo and problem gone.... thanks for you help guys!
