Motherboard (EPOX EP-8K7A) or CPU failure? No POST screen.

All I get is a black screen on the monitor when I turn the system on. No POST no nuthin`.
Running XP Home W/SP2, been fine for a couple years now.
512 MB RAM, 1 20GB hard drive, 1 60GB hard drive, w/ three 20GB partitions.
VGA card. 1 CDROM, I CDRW,1 31/2 floppy, 450 watt power supply. Here`s what I have done up to this point.
Changed to a known good monitor.
Tried a different PS2 mouse, the Logitech cordless has locked up two or three times, recently.
Reset CMOS, no help, installed new CMOS battery.
I haven`t tried a Video card ,yet.
All the fans run. The LED`s light This EP 8K7A Mo Bo has a pilot LED and two trouble shooting LED banks They read "FF" If I remember they should show several different displays when this runs a normal boot up.
At present the only devices connected to the MoBo are the keyboard, mouse and monitor. Any suggestions as to what else to try? I haven`t been to the EPOX WEB Site, yet. I`m running on my spare computer now and already miss MY XP, This is M.E.
One other thing, I tried to boot using my XP Disk, no joy, I`m sure my boot sequence was set to boot from CD When I tried it.
Thanks, ahead of time!
I forgot to mention I use AVG anti virus and it downloads every morning at7:08 and scans for virus at 8:00. Everything was OK then.

Does the monitor power up past standby?
Not just sure what you`re asking. I turn all my devices on from a switched bar if receptacles and the monitor indicates by it`s LED`s that it`s receiving power.

Do all the Leds come when you power up? Hard drive, optical drives
Yes they do with the exception of the 3 1/2 floppy.
I`ll try another Floppy drive If you say so. I did have it disconnected but I hooked it back up.

Do you normally hear a BIOS beep on start up. No.

As for hearing the hard drives, the CPU fan makes enough noise I can`t hear them but they`re both warm and vibrating like they are turning.

I put a PCI video card in and took the AGP card out.Same results Still a black screen.

 

Thanks Pete.

Hi Moore,

Suggest investigating the RAM. Pull and reseat the stick(s). If you have more than one, just try one at a time. Try it/them in different slots. You can try cleaning the connectors with a soft pencil eraser.

After those, try resetting the CMOS again.

Check the motherboard for any swollen or leaky capacitors (the cylinders standing off the board).

Thanks,mattman,
I tried all the advice no results. after reading Daaanii`s thread below, I`m going to remove the MOBO and try it again away from any chance of grounds and see what happens.If that doesn`t straighten anything out I`ll have to see what procedure I have to go through to install my XP on a new MOBO or on this one I`m running here and now. That will be a whole new thread. I`m not sure of the appropriate forum. I assume XP?
Thanks again to all hands, I`ll report back if it comes to life.

Hoo Boy I`ll bet I can use that!
I`ve been looking but hadn`t found the instructions I thought I needed. Thanks

I'm NOT gonna say it's definately the mother board but I've ran 2 different Epox boards and both failed sooner than you've been running yours.

 

Thanks for the heads up Jaylach.
I`m going to order a new ASUS board,I got one on advice from this board earlier this year and it installed on this computer I`m using now, smooth as silk. I`m going to start a new thread on this in this forum, I`ve got some questions on what to order.

I like Asus! But remember that I am NOT saying your Epox board is dead, only my experience with them.

 

My Epox 8KHA+ has been running strong for a couple of years. You should see different LED sequences before the FF (which means the board is fine) while booting up. If you cannot see any bad capacitors I would tend to believe the CPU has gone bad. Another possibility is the hard drive IDE cable or 4-pin molex power connector is loose or bad.

 

Thanks, Pete,
Stick with me, you might get me educated, yet!

 

Gulp!

That`s not my definition of light reading! I came out of there concerned that my disk purchased from Newegg was an "OEM" disk, and won`t let me change motherboards. I made this computer that crashed from some new,some used parts. The CD came with the COA glued to the shrink wrap and I put it on the front of the computer.
The C drive is one 20Gig hard drive with only the OS on it,The D,E,F,are all 20 gig partitions on a 60 gig, drive, with text, media , and photos saved on them.
Am I in trouble?

I`ll wait and see what happens.
I may have pulled a forums etiquette "boo boo" by posting anew. no harm intended if I did.

Moore,
One thing to keep in mind is that cpu failure, IMHO, is extremely rare as long as they are kept from overheating. But, heck, in my experience, any failure of any PC component is quite rare.

If you are not able to isolate the offending component before you rebuild with your Asus, you could encounter the same problem in the new setup. I suggest you pick up one of those cheap power supply testers.

My friend rebuilt his rig after his PSU destructed and left a nasty burn on his mainboard. Amazingly he was able to replace the PSU and keep running. But eventually it seems to have caught up with him as he is now encountering multiple hardware failures with his other components. He keeps replacing one and finds that another is failing as well. Guess nothing was immune from the PSU "flash out ". Oh the joy of PC maintenance/repair.
