Pc Boot Problem
Posted 19 July 2004 - 09:34 PM
I tried to replace a CD device with a new one.
After replacement my computer woun't boot !
I come back to initial cfg but the same thing !
The computer try to boot after pressing power push button but it's stop before appearing any message on sceen moitor.And no debug beep !
This time power led is liting intermitently ( like in stand-by mode)The fan , harddisk and CD are powerd !( I can efect manualy CD).
Also i can stop computer by pressing pwr push button.
I tested power source (ATX) on other computer that is booting OK !
So i conlude that power supply is OK !.
What anything else could be ?

I suspect with your jumper settings...Mind you one thing. Both HDD and CD-ROM are primary disks by default as a new one....Later we could change as our wishes...
now your HDd may be primary. So change the jumper of CD-ROM to secondary or just remove it. Now try yourself...i hope it will work no properly....

for a PC with an IBM ROM BIOS chip, no beeps is the sign of a bad power supply or system board failure
For a PC with a Phoenix ROM Bios chip, no beep is the sign of a CPU register test failure.
The alternative would be to figure out the system manufacturer, and see if there is any technical info on their website that could help.

I think some slutions.
1.Did u see HDD on the BIOS Table?
2.Did you try boot with Win98 startup discet?
3.Did u try HDD another machine? May be Its failed.

check if the motherboard is not grounding somewhere with the chasis.
also inportant thing to check is the onboard battery i have come across cases where the battery gets shorted and could result in such problems, so you can try replacing the cmos battery it could solve problem.
the best way to trouble shoot hardware problems is as follows
1. remove all device such as hdd, cdroms, dvds , check for display if there is beep and display good connect other device in priorty of hdd, fdd, cdrom, any other addition peripherals
if this dosent gives display, remove memory from slot , clean the contacts with isopropyl if nessesary and reseat properly
if it has a display adapter which is not onboard remove clean contacts and reseat.
if you suspect a power supply problem , check for voltages on the yellow black, red black pairs for 12 v and 5 v respectively.
next to check is the power-on button in case of atx power supply, disconnect the soft poweron button, there is a 2 pin jumper on the mainboard known as atx power on short it with a metal screwdrives , this is akin to pressing the soft poweron button, the will isolate the problem of powerswitch if any.
sometimes there is also a problem of bios seating if it is socket based, a slight push on the chip will reaseat it properly.
IMP: keep the power supply off when you add remove components, and touch your bare hand to some metal part on the chasis or metal surface before touching static sensitive parts as it helps in dissipating the static present on our hands which could damage sensitve electronic components.
HOPE THIS HELPS

There are many possiblilites. Some of them are as follows
1) While you are connecting the other hardware divice you might have phyc\sically damaged the Hard drive pins or the harddrive cable first check for the hardrive cable.
2) the boot sector might have been corrupted. Just try to boot with a win98 bootable media type fdisk /mbr or if you are using win2000 then use the repair option in the cd
3) the bios might have been corrupted. Try this this works out some time but i stronlgly recommend to be very careful while doing this. Remove the bios and try to short the pins with a screwdriver and then put it back. Once i have succeded doing this.

Unfortunately you right !
My PC motherboard is dead.
Hope you will never have same problem.

If there is no Physical damage to your mbd may be your Bios has corrupted , you can try reprogramming it in any TEST& Repair centre , where they have BIOS CHIP writers.
Asus MBD had few issues like you mentioned . Asus has agreed to replace these MBD from field ( I remember it was some MOSFET problem they replaced with new version of MOSFET which in turn control the POST )

Disconnect all CD cabels.
Try to boot with only HDD.

If that doesnt work reseat the processor and memory (Have seen issues like this before in work where this was the fix) and reseat all IDE/SATA Cables on the system and check jumper settings
If all else fails you could sub in some know good parts to eliminate parts down to a single point of failure.
Hopes this helps

Remove the data cable from the mother board.and remove the powre cable fome both hdd and cdrom. and take the ram out and check there is beep or not
of there is a beep put the ram back. and if the display comes than check tha cable and install it once again

are you sure that the cable's conneting correct?
Could you rebuild the old hardware?
