Help.
My daughters Sony P4 3ghz HT Vaio desktop has always had problems - mainly motherboard related but recently one of her two screens starting intermittently blanking out for a second or so. As it is now out of warranty I decided to try and salvage the good bits and put together a box that could last her for the next year or so.
So I took the following existing bits out of the Sony Vaio
- Pentium 4 cpu 3ghz hyper threading
- 1.5 gb of RAM (2 x Kingmax 512mb DDR-400 and 2xProMOS 256mb DDR-400)
- Sapphire Radeon 9600 Atlantis 256gb vid card
- Hard drives and DVD drives
- Dell 1905 lcd screens
And added them to the following new components
- Antec Sonata II case (with Antec 450 p/s)
- Intel D965PERL mobo - and when that didn't work (see below)
- ASUS P4P800-E DELUXE Socket 478 mobo
- new 200gb hard drive
Problem is that on both the Intel and the ASUS mobo, the PC powers up but nothing happens - the screen remains blank, no sound is emitted (e.g. no beeps under POST) and nothing happens. There is a momentary lighting of the lights on the keyboard (connected by PS2 or whatever that old non-USB connector is called) and the DVD drive will ight up and open/close but no boot screen etc.
I did a quick search here and tried the following - none made any difference
- swapped out the cpu for another (older) 478 P4 I have in another Vaio
- tried a total of 4 different vid cards (and verified that 2 were working on other PC's)
- tried removing then replacing all the components
- tried various combinations of memory (1,2 and 4)
- removed all other non-essential components and disconnectednon-essential cables (including IDE, floppy, etc.). Leaving only the following in an attempt to reach the initial boot screen: the motherboard, CPU, RAM, power supply, and graphics card.
What am I missing? Is there some kind of compatability issue with Sony VAIO P4 cpu's - am I screwing up in some other way.
I'd really appreciate any guidance or pointers - I'm dead frustrated right now.
Many Thanks - and happy new year.
