So i got a used custom built pc, it's got a tforce4u board in it and a little red light on d13 by the jcmos1 part of the board. No matter what i do once i turn the pc on, whether i try to load an OS, or look around the bios, it turns off at around 40 seconds. Also, when i recieved it in the mail it's heatsink was hanging off. any thoughts?, let me know if i left out any pertinent info.

When you reattached the heatsink, did you clean off the old thermal compound and add some new compound (very small amount)?

The suggestion made by Robert...is the normal suggestion that one can expect when talking about damaged/defective items recently purchased...if covered by a warranty.

OTOH, if the system was purchased "as is" and no warranty applies, it sounds to me like you have a lot of work on your hands. You need to find out, component by component (and this is not easy) what works...and then move on from there to figure out what doesn't work.

Just to get you started...

Can you actually get in the BIOS?

How much RAM installed?

How big a hard drive? Is the HD recognized properly in the BIOS?

Do you have an XP CD with a legal license? If not, what O/S were you attempting to install?

Have you checked all connections and seating for cards and RAM?

I can get into the bios, and look around unitl it turns off.

I have 2 x 512 sticks

1x160 gb IDE and 1x120 gb SATA

XP with legal license=yes!

I haven't checked ALL the connections and seating but i have checked some of them.

I will get some of the thermal Paste at a computer store tonight and try it this weekend.

Clean off the matching surfaces with rubbing alcohol and use a small drop of compound spread evenly and as thin as possible Hopefully it is shutting down from overheating and this will solve the problem. It's the most obvious, but be prepared to troubleshoot further as Hamluis stated
