new pc strange boot cycle

crowej

i am having a strange problem when i boot up my machine, it will get as far as loading personal settings on winXP the it will reboot again, it will do this about 5 times and eventually boot into windows. also if i try to shutdown the pc will shut down and all fans etc will go off but about a min later it will turn back on.

any idea's ?

my spec is:

win Xp media center edition 2005
AMD Athlon 64 X2 4400+ 2.2GHz Socket 939, 2MB cache
XFX GeForce 7800GTX 256MB GDDR3
Corsair TWINX2048-3200 DDR-DIMM 2048MB Kit w/two matched

Has it ever worked okay or is this a new config.

First place I'd start is the power settings in the Bios. I'd also try booting first time into safe mode. Is the PC stable in Windows after it's been through the reboot routine?

its a new config, the shutting down problem was there since i built it but i installed a new dvd rw drive over the weekend and thats when the powering up cycle started

I'd try different ID and cable combination on the drive to see if it sorts it.

That's an awesome machine!

The RAM should be in the orange slots, is it? It could be that simple.

thanks - i was wondering if anyone would comment

not sure i will check if the ram is in the orange slots

Its most likely ram. It sounds like the ram bus speeds are different

i moved the ram in to the orange slots on the board problem resolved and huge preformace increase
