Yeah I've been taking out the battery. And I just tried with 1 stick of the fast ram and got the same result.
So I put my Kingston Value Ram 1066 back in ... and it now boots normally etc. !
What does this mean?
I paid £250 for the good memory and I'd really like to use it!
2GB CellShock DDR3 PC3-12800 1600MHz (7-6-6-18) Dual Channel kit
The motherboard is an Asus P5E3 Deluxe Wifi
Before I updated the BIOS (was 301, now 903) it wouldn't even boot with this faster ram in - so I've made some progress.
BTW I checked the controller mode in the bios and it's IDE, not AHCI. The hard disk and DVD are SATA.
