Hey,
I've never built a PC before.. but have upgraded and know the basics.

I had two cases/systems and took the best from both to make the best of both worlds.. (I got this done at a shop).. now I want to use all the leftovers to make a system.

I've never done a CPU/fan and I got some thermal tape, or paper? weird stuff.. did what it said on instructions, put it onto the CPU then the fan/heatsink ontop.
Hooked up all the PSU cables needed, one harddrive and then tried to boot.

The first screen came up then a few seconds later the power goes straight off. I tried getting into the BIOS setup but still after a few seconds it goes off.

What could this be?
I don't want to have to take this to a shop and pay for probably one little issue to be fixed..

Asus P532-E SLI-PLUS motherboard
Dual core processor
2gb RAM

If you need more info to help me please ask!

Thanks
David

Sounds the you fudged up on the thermal paste. I take it apart, clean off all the current paste with rubbing alcohol and then reapply. Get thermal paste that comes in a syringe, like Artic Silver.

Try it again. If its only on for a few seconds before it shuts off, it might not have time to heat up to shut off levels but its worth a try ($5). Also try resetting the CMOS using the jumpers on the mobo. Make sure your mobo is on stand-offs and not shorting out. Hope that might help, cant think of much else.

Thanks..

I can't believe a CPU gets that hot that quick..!
I've tried again with the tape but i'm looking into getting artic silver and some contact cleaner as I think the tape isn't up to scratch..


Also, another system question while i'm here. What does a long continious tone mean on boot?
