Ok going on 10 days trying to get this PC I'm building together to work. Here are the specs

Intel Pentium 4 Socket 775 processor 651 3.4ghz
ATI 9800 PRO AGP 8X
2X512mb Crucial PC-3200 400 DDR
500gb SATA Seagate 7200.10
Cool master heat sink (up to 3.8ghz)
A-Power Pure Black 580W SATA Dual Fan ATX Supply

And so far tried both these motherboards with no luck

Foxconn 661M08-FX-6LS SiS 661FX (built in graphics)
Foxconn 865PE7MC-S (no graphics)

Powers up with both motherboards but no graphics (with AGP and On-board)
heat sinks spin on both motherboard and video card.

Lights on motherboard work. hard drive spins up. everything seems fine but nothing ever comes up on the screen. tried different ram also (crucial 1gb PC-2700 333 DDR which work fine in my fathers dell pcs) both motherboards say they use 333/400DDR but nothing also cleared CMOS and still nothing:confused:.

Going to try another AGP card but not sure if thats it cause the on-board graphics showed nothing but a blank screen as well. Does this sound like a bad processor? no beeps come from the motherboards also to indicate something is wrong and nothing smells like its burning.

My 478 build was a piece of cake but this 775 is being a PITA. might just sell it all and get a pre-built even tho I don't wanna.

Anyone have any suggestions?

Thanks.

Welcome to the Forums ions :)

Don't overlook your ATX12V cable, which is the secondary power cable that has two yellow wires and two black wires in a square plug. The motherboard will have a separate receptacle for it, and it usually powers the CPU, so check to be sure it's plugged in.

If that isn't the issue, maybe try benchtesting the motherboard and the bare essential components (RAM, CPU/heatsink, video, NOTHING ELSE) with the motherboard on a non-conductive surface such as cardboard, outside of the case.

Thanks. ATX12V was plugged in and still nothing. Will try what you suggested.

Well found something on the motherboard without graphics. Seems like one of the 775 socket "pins" is bent. Could be before or after I first installed the cpu. gonna try the motherboard with on-board tomorrow cause I don't have a spare VGA cable laying around (just have DVI)

Could I have messed the processor up by installing it into a motherboard with a single bent "pin"?

The processor should be OK. Good luck with the other board :)

Cpu should be fine, also if you are very careful you can often times fix the bent pin

Well neither motherboard works now cause my girlfriends dog decided it needed to throw up on my damn motherboard as I've got it on a piece of card board trying to trouble shoot.

Thinking of just getting a bare bones pc set up since I have the ram,OS,hard drive,video card and processor already and selling or giving away the rest.

what do you guys think of this

MSI Bare Bones at Newegg.com

Thanks again guys.
