A7N8X-2800 Fried?

[plumbertom]

Well, I don't know what happened but I was checking out one of the forums and my computer when't into the blue screen mode and restarted. I got my desktop up then it went into the black screen mode and restarted. It went as far as the Asus logo and black screened again. Now I can't get anything. I shut the power off to the monitor and computer and plugged them back in and restarted. The only thing I get is the monitor says....No signal imput or cable is disconnected. Then the green light changes to amber. I will reset the computer and it doesn't do anything at all. I don't get anything on the monitor and the amber light just stays on. This system was very stable with no problems I have had it for a couple weeks now. I don't know if it is a video card thing or the CPU. The data light on the box doesn't do anything either when I restart so I'm thinking it is a CPU or Motherboard thing. Anyone have some suggestions I'm pretty much an amature.
Thanks for any help.

When you turn it on, do you hear anything like the sound of fans spinning up? If not, chances are that the power supply may have experianced a surge or fluctuation of some kind and flown south on you. You can nab a new 400 Watt AMD Approved power supply online from NewEgg.com or try a local computer shop or retailer (Office Max, Staples, Best Buy, Frys, etc.)

Once installed, I would try reseating the RAM and all your installed PCI & AGP cards. Also, there should be a jumper on the motherboard that'll clear the CMOS (check the manual of the board). After that, power up and see what happens. If that doesn't work, looks like either the motherboard or CPU went the way of the dodo. :(

Thanks for the reply Psycho.

I did check the fans last night and they are working (case and CPU}. I do have a generic power supply that I am going to replace with an AMD certified one. I'm going to reseat everything and clear the CMOS and see if that helps. Crossing my fingers now.

Here is my disaster-relief strategy when I run into problems such as this...and it's worked 95% of the time... :D

First, remove the CMOS battery...Stick that to the side until we're finished...You can also short the CMOS jumper ( in addition ) if that is one of your habits..just be sure to put the jumper back int he right position before you power things back on!

Remove all of the components in your system...memory, HD tray, graphics card, etc....

From scratch, install only the CPU, memory, and graphics card...No HD, sound card, etc. should be installed.

Once everything is installed, throw that battery back in...

With any luck, you'll post the BIOS and be able to navigate through the options...Just for grins, check the System Health tab to verify that all voltages and temperatures are within reason...You want to keep an eye on the CPU temp especially to make sure some thermal runaway isn't causing your black-screen....( Not sure if Asus has a built-in protection feature which might kill the power if this happens....could be what's happening )

Well...if that works, you know the drill....Throw everything else back in and count your good fortune...

If this doesn't work....post back here and let us know what happened.

Good luck!

:D

Well, its not looking good.

pulled it all out, reset CMOS according to the manual, did the jumper reset re-installed everything put battery back in fired it up. same thing. The monitor says "no signal imput" then goes into sleep mode. The motherboard led light is on fans running but no beep codes. I pulled everything out again. went thru the same procedure this time left the hard drive disconnected. Same result.:( What do you all think. Mother board?

I got this in a package from New egg. If I have to return it should I send proccessor, motherboard and memory back or do you think memory, proccessor still good. I don't want this to be a return festival that gets strung out for a few weeks. :)

Thanks for all quick replies:)

[pelly]

Well...that certainly doesn't sound good. If possible, do you have any other DDR you could try? ( it's a long shot since it was apparently working before )

If possible, could you borrow a friend's CPU to see if something cooked?

Hate to say it...but it looks as though the magic PFM dust escaped either your mobo or CPU...

:eek:

[gokickrocks]

im leaning towards the motherboard...many others have reported dead boards as well

[plumbertom]

I think I will get ahold of new egg and send the m/b and cpu back. I don't know anyone off hand that has some memory I could borrow that is DDR. What a bummer :( I hope I can get it back soon. I'm in a gaming league and my old computer is like playing in lego land, graphics wise. I was getting kinda spoiled with this rig :)

When this is all said and done I will repost on this thread to let you all know what happened. Thanks for all the advise. I posted here 3 times and had great feedback all 3 times! :)

Video card all the way. I've had a dead motherboard and all that would happen is a fan or two twitching, no power, etc. I've also dealt with dead and missteated vieo cards. Pop your card into a friend's rig or see if you can borrow one for your's. If it's a signal to monitor why would it be the motherboard?

[plumbertom]

I'll switch my card over to my old computer. But I'm still not getting any beep codes on the motherboard:confused:

[pelly]

LoL....Sounds easy enough eh? :D

Many times when no signal is present to display, it is because the BIOS is hung at a step prior to initializing the display aspect. Everything loads in a specific order....If it is a problem with the CPU, mem, or mobo...they typically will all result in nothing being posted.

Were the beep codes present with the absense of video...I'd say the graphics card might be cooked. However, the beep codes are one of the initial steps to diagnose events as the BIOS loads...If it hasn't even gotten to this step, it doesn't look good...

:cry:

[plumbertom]

well, not good

I'm running the card in my old computer right now and its working fine. Good for the card, bad for the mobo and cpu. At least I don't have to buy a new video card. :)

Make sure your PC speaker is connected to the correct slot on your motherboard..listen for the beeps..

Try swapping your CPU if you have an extra..

You also stated that your LED light is on..What color is your LED light..You should have 2 of em..One for the AGP and one for Power..

[plumbertom]

The led light on the mother board is green and its on the bottem left side of the board. The case power light is on and green. The data light is not blinking at all (the one on the case next to the case power light). it used when everything was working right. I don't have any extra cpu's to throw in right now. I can't use the one in this rig. speaker is connected too. It was working good before also. Well, got all my paperwork in order for the big phone call to newegg. I hope everything goes smooth. I have bought alot of stuff of them and this is the first time I have had equipment failure and had to return something.

[plumbertom]

You guys have been great. Let you all know tomorrow after work whats going on.:)

[scott123]

Wait a second...have you removed (unplugged) your hard drive and see if it POST's? Sometimes a bad hard drive can cause such an error.

[pelly]

Read my first post waaaay up at the top of this thread....must have missed it...

:nono: :D

I recently had a hard drive die, thanks for this bit of info for future reference.

[Firelord-OCHW]

I couldn't read anywhere have you tried it out of the case ie running just CPU, Mobo, RAM and Gfx (and psu obviously :p)

Just a thought as something could be shorting it out :)

Worth a last ditch effort??

[plumbertom]

Hey guys, called newegg form work and sending the whole deal back. cpu, board, memory. I'm switching the memory to 2 sticks of corsair 3500 512 xms.

Hey pelly, I couldnt find any thermal reset anywhere in the book. The Asus utility has a thermal shut down and temp monitoring tool that you can run, but it seems to be a software deal. I quick scanned the book a couple of times but I could have missed it. I would think they would have something like that unless clearing the CMOS does it.

Firelord, thats pretty much the only thing I didn't do but its to late now :)

[Riff]

Could have been the power supply or the CPU. I have the same setup that that you will be getting (A7N8X + 2800 + 2x 512 PC3500) and had similar problems. The fans would turn on but I wouldn't get any video and no POST report. I ended up ordering a second A7N8X and got a replacement 2800 chip. I paid a shop to install it and it worked (but with a 550W Antec TruePower PSU I bought instead of the 420W Austin that was being shipped w/ the newegg Chieftech cases), however, they also diagnosed my first A7N8X and said that it worked just fine with the same memory.

[plumbertom]

I had a "bust out" 400 watt (Duro) that came with the case that I used (I know, not a bright move. DOH!). I got to thinking about the power supply also, so I ordered a Enermax EG465P-VE(FC) with my return order just in case. Now it is the big wait. :(

[fasedww]

Make sure you have the cpu fan rpm monitor plugged into the motherboard or it won't boot either and then shut it off in the bios later if you don't want it on

[plumbertom]

Thanks for the info fast E.:)
