i have a custom built pc:

Abit IC7-G
P4 3.0
Nvidia Geforce 6600 256mb
36GB Raptors
2GB Ram

my computer was running fine till last night (but felt weird as it gets "stuck" for a moment or two...)

this morning, turned on Ok, shut down Ok,

this afternoon, turn on, all sounds ok, but no beeps, no video, no HD LEDs blinking either.

tried the graphic cards on other systems, works,
tried a old pci (non AGP) graphics cards, no video...

totally clueless now, pls help. got a lot of stuff to do this week.

Pull everything out except CPU, RAM, Video card and Motherboard. Start with one stick of RAM, if it doesn't boot, try the other. If you do not get any beep codes or POST, it's either a dead motherboard or dead processor.

Just tried out as you said it.

Kept only MB, Video, CPU and RAM,
swapped each of the ram individually, No Good.

Tried the CPU from this on another P4 motherboard, No Good.
Tried other CPU on this motherboard, No Good.

what now?

please, be kind and don't say get a new system.

At least your CPU is dead, it's also likely that the motherboard is dead.

Just one thing... in my frantic state of mind, i was not thinking straight...

using P4 from an old board Asus P4T on IC7 and vice versa should not damage anything right?

hope i din't mess up 2 boards / cpu's

 

[DaiShan]

Under normal circumstances no.

Quick question ... are you using the same PSU for all your parts testing? If so, try a different power supply before buying new hardware.

If you're dropping the cpu into a completely different, known working system with a different PSU, then disregard.

well, something else to consider is that the P4T is an older RAMBUS based mainboard, and as such won't likely support later revisions of the P4, such as a 3.0. The later model 3.0 is likely a Prescott core that won't work on the P4T either, so unless you are sure one board supports a later CPU, you really haven't eliminated either component as the source of your trouble.
