Computer Will Not Turn On

Ok, here's the deal:

I had to update my motherboard back in May, along with my video card and chasis. Everything was well and good until one day in July, my roommate was playing LotR: BfME and all of the sudden it just froze. Nothing happened whatsoever, I tried everything. So, I resorted to a hard reboot. Next thing I know it won't boot up. Nothing happens on the screen.

So, I took the compy back to the shop that I had worked with before to get the new mobo and such, and after some testing they claimed that my mobo (socket 478) went bad, so they got a new one under warrenty. Next thing I know I get a call from them claiming that it was not the mobo, it was my processor. Evidently a bad chip, though I have been using it for the past three years (P4 3.0ghz, 800fsb, HT).

So, because I really had a hard time finding an affordable chip for the 478 socket, I found a deal on newegg that gave me an AMD mobo and chip combo. So, I just got it and replaced it tonight. I hooked everything up correctly, and hooked the external parts up. Nothing on the screen happens, though all the lights and fans work fine.

I tested my monitor by hooking it into an old laptop, works perfectly.

I do not get a POST beep until I just have CPU, RAM, and IDE1 (CD / DVD drives) hooked in, yet still nothing on the screen when I turn it on (the new mobo has onboard video, I have tested with both my video card and this). The beep is just a regular one beep.

Any ideas?

Thanks in advance!

First thing, clear cmos, either by jumpers if you know which ones or by simply pulling plug on power supply and removing m-b- battery for a few minutes, i guess your ram may not be compatable with your new board, and possibly your power supply. ide 1 or primary is for your hard drive, secondary is for dvd-cd rom. ed

 

Tried both of those suggestions, and still not much to go on. I did get it to beep a few times in one configuration, but nothing on the monitor no matter what. Could it be a power supply issue? It's running over 200 watts...

I think you need to borrow another power supply, just use cpu, ram and power supply, with onboard video . This will get you into bios[post] if them parts are compatable. You dont need the hard drive or cd rom hooked up to see if it post's. ed

 

Additionally many newer mobo's have a second power connection (4 pin I think). I ran into a similar problem and it took me a bit to figure out there was a second power connection.

Odd are that is not the problem tho - but it is always good to explore all options.

Good Luck !
