I just upgraded from a Pentium 4 HT to a Pentium D Dual Core. I turn it on. There are no beeps. The power lights do not turn on. The fans work. The CD ejects and scans. Nothing gets to the monitors. Any ideas?

Check you memory and cards. Make sure they were not unseated while you were installing the new CPU.

hi,

thankyou for starting a new thread, do you have another monitor to try ?.
so we can rule out a faulty monitor.

cheers...xxx1

I am not at home right now, so I can't check the ram. I don't think they are loose, but I will check anyway. I don't have a separate monitor. I do have a dual monitor configuration. Should I try just hooking one up at first? What other posiblities could it be?

[Lord of the View]

Ok. I just got home. All for RAM cards are firmly in place. All cables to and from the hard drive is secure. I took the new CPU out and put the old CPU back in and it turned on perfectly.

Any ideas? It's a brand new CPU. They are both LGA775. The Abit site says that it should work. Is there anything I should do in BIOS before I install the new CPU? I haven't had to do that before.

With what you just stated I would believe you have a bad processor.

After further research, I have found that the chipsets are different. The old one is 925XE and the new one is 945G. I do not know what a chipset is so I do not know if this could cause the problem. If it does, how can I remedy this?

Do you know what kind of motherboard you have?

on ur MOBO look closely for a CMOS jumper... also states on ur MOBO installation book.. try switching the pins http://www.sysopt.co...000/09/batt.gif go there and see that black thing on the higher side of the blue box around the CMOS jumper u can take that off those pins and switching em to the bottom 2 instead of the top 2 and vice versa soo first switch em to the opposite of what they are now and then turn it on.. it should work. but after reset them if the Monitor doesnt turn on.. maybe thatll fix it

[Lord of the View]

It's an ABIT AA8XE. What does switching those jumpers do?

[XsNRG]

ir resets the BIOS and if it is on the wrong one the motherboard wont turn on..

[Lord of the View]

So even though the CPU and motherboard use different chipsets, I can reset the BIOS and it will work?

[XsNRG]

chipsets have nothing to do with ur problem so yes.. try messing with those jumpers

flashing your bios is going to have no affect on your situation if your motherboard does not suppot the cpu. It has nothing to do with jumping the cmos and everything to do with voltage regulation from the motherboard. Which cannot be fixed without getting a differen't motherboard. You can upgrade you bios to a higher revision by checking the site of you mobo manufacturer, but other then that you would be best advised to get a new motherboard

Well, I tried resetting the BIOS, with no change. I just put the old CPU back in. I'll get a new motherboard later. It's not a priority. Thanks for the help everyone.
