New ram+processor, MOBO or VidCard dead

[acidcore]

I have a D865 PERL MOBO, 4x512 Kingston HyperX 184pin DDR400 ram w/hyperspread, 3.0Ghz 800Mhz FSB 478-Pin Pentium 4 Processor w/a prescott core, a 450w PSU, 36GB Raptor WD HD 10000rpm, 100GB WD HD 7200rpm, a dvd-r/rw 4x, a Digital Research 52x24x52 Internal CD-RW Drive, a GeForce4 TI4800 SE 128MB DDR AGP 8X w/ TV-Out & DVI, and a 15" MultiSync LCD flat panel monitor. Around 1-2 weeks ago my computer was running fine, I only had 2x512MB Kingston HyperX in it then and a Intel Pentium 4 2.4GHz 533MHz 478 pin CPU. I installed the new 3.0Ghz processor and my comp ran fine with it, then I installed the ram and a week later (which would have been yesterday), my computer will not output video to the monitor. The monitor has been tested and works. I have tried taking out the new ram and processor and replacing them with the old and still the same problem. I think I may have burned out the Vid card, but the fan that is on the vid card runs so I am not so sure. The PSU is tested and works as well.

I think it may be my MOBO though because today I took off the heat sink and turned the cpu on to see if the processor would get hot since it seemed like it wasn't starting on the boot. (This is not a very smart nor good thing to do, I do not recomment trying this). The processor was cool as could be. I also noticed that my case fan on the same side of the MOBO wasn't working, but the VideoCards fan which is right near the Case fan was running. The PSU powers up and turns on all the drives, and they all work fine. I cannot get any video output at all though and I thought it may have been the Vid Card, but now I think it may be the processor. Any thoughts? Thanks.

What brand is the PSU? it could be taxing the system. Is the monitor powered by the PSU as well or not? When you say it is tested, what do you mean? Just because it works doesn't always mean it is working properly. I have learnt this the hard way... sure the mobo could be gone but it would be good to rule out a few things first.

You are a braver man than I for running the CPU without H/S and fan.

Nevermind, I'm stupid.

I've come across Intel motherboards that don't work if Dual Channel mode is enabled. Have you tried running the system with just 1 stick of RAM yet? If the motherboard works with just 1 stick of RAM but doesn't when Dual Channel mode is enabled, RMA the motherboard to Intel.

I have tried the MOBO with a single stick and still the same results. No I don't believe the monitor is powered by the PSU. I believe the PSU is working properly though because it turns on all of the drives and some of the fans spin, but it just seems like the one side of the MOBO nothing works on it. Could this be a PSU problem? RMA the MOBO to Intel? Explain please. Thanks for the help.

The PSU could still be the problem even if the LEDs go on, the drives spin up and the fans run. What brand is the power supply?

Yes.

RMA = Return Merchandise Authorization. You call Intel and tell them the problem. If they feel the motherboard is defective they'll give you a RMA number and an address to mail the motherboard to.

Unfortunately the PSU was given to me w/o a box a year ago. I looked on the PSU itself and I believe it is an Extreme Power 550w 115VAC PSU. It just looks like some cheap off brand. Also lately my PSU has been making a loud buzzing noise every now and again when it was on. Maybe this is it dying? I tested it 5 mins ago and it still is making that noise. Thanks again.

If it is not the PSU any other ideas? I am going to buy a new PSU and try it since I can't get a spare one. I figure if that's not hte problem I can always return it. Thanks for all the help so far, I just wish I knew exactly what it was so I could just replace it lol. Thanks again.

On a side note I have just one more question. I thought my MOBO was dead b/c my processor and vid card both won't work when I turn my computer on. I also noticed that the MOBO was working for the other components in my computer. I was just wondering if it is indeed my PSU that is dead? Or could my MOBO be dead and still get these same results? I have narrowed it down to either the MOBO or the PSU and I would much rather just have to buy a PSU instead of a new MOBO. TIA.

It would be wise to get a new PSU anyway. With it being a generic PSU it could have taken out the MB or at the least part of it. And if your MB is less than 3 years old, it won't cost anything if you RMA it back to Intel. All you will have to do is call Intel and explain to them your problem. They might ask you what trouble shooting you may have done, and all you have to do is explain it to them. The least they could do is say no. But if your MB is less than 3 years old that isn't too likely to happen. Good luck.

Between an off-brand power supply and a Intel motherboard...I'd suspect the power supply as being the problem before I'd suspect the Intel motherboard.

Just curious...how many 4 pin power connectors does that 550 watt power supply have?

Cricket, I suspect you are right. I decided I am going to buy a new PSU because after talking with some other people they also feel that the PSU is probably the bad part. I am guessing a 350-450w PSU would be enough to power my specs which I have previously posted. Thank you for all of the help. You guys at PC Mech are great. I will get back to you on the 4-pin connector for the PSU. Thanks again.
