I have been trying to build my own computer. I have it all assembled and have powered it up but that is as far as it goes. When I switch on the screen remains blank no Bios set-up.
The set-up is as follows
AMD Athlon 1.2Ghz CPU
MSI Ultra (MS6561) Ver. 10 Motherboard (built for AMD CPUs)
256Mb DDR Ram
ATI Raedon 128Mb AGP Graphics card
I have tried two hard drives, one, which I know the boot up sounds for, and it is working OK. I have also tried two keyboards and two floppy drives and also tried a PCI graphics card. When I use the Raedon graphics card the monitor stay on, when I use the AGP graphics card the monitor switches off.
The floppy drive light stays on permanently, the keyboard lights flash on as normal at switch on but then nothing. Everything is properly seated and plugged in. The CPU seems to be getting power as it heats up rapidly (without heat sink and fan for about 3 to 4 seconds then power was switched off and heat sink and fan replaced) I get no beeps as start up
There are no jumpers to be set on the Motherboard except for one set to clear the CMOS, which I have not touched.
When I was assembling the computer the case was earthed and was used to remove any static from me before and during handling the components.
Any one got any ideas what might be wrong? Any help at all would be greatly appreciated.
Thank you

well, for one thing, you have the floppy connection backwards if the light stays on, and the part about taking the cpu fan and heat sink off is a major no no, even for a second. burns up the cpu. i'd still recheck your bios settings, put the card that seems to work in there. after rechecking the manual for connections, voltage, memory jumpers, etc, and try again. you may have burned the cpu for those 4 seconds, so be prepared to put out for another one if that is part of it.

Thanks Win
Since posting last I have installed onto the motherboard a 'D-Bracket
Connector' which comes with the board. This a USB Bracket integrating
four LEDs and allows users to identify system problems through 16
various combinations of LED signals. When I switch on the computer
the signal given by the LEDs alternates between 1)Memory Detection
Test and 2) Early Chipset Initalisation. For the Memory Detection
Test signal the manual quotes 'Testing onboard memory size. The D-LED
will hang if the memory module is damaged or not properly installed.
Does this mean that the 256Mb DDRam and the CPU are both faulty? I
have already removed and replaced the memory so I am sure that it is
seated properly. I have already removed anything which was not
essential with the same result - Nothing.
The Clear CMOS Jumper is still set in the Keep CMOS position which it
was when I took delivery of the board.

Again Thanks

if you can get a hold of a friend that has a spare that he/she's willing to help you test it with, try another cpu before buying one yourself, saves some money. other than that, it could be a DOA (dead on arrival) motherboard.

Hi,
I've got a problem with my computer that has been running OK for some months prior to this.

The computer turns on sometimes but then occasionally completely loses power and I have to manually switch the button on the back of the case on/off a few times before it will start up again. Sometimes the power will stay on, sometimes the same thing will happen again. If that's not bad enough when the power does work the system cannot detect the HDD (not even in BIOS)though I get one beep and the LED on the MOBO reads correctly. Now strangely again sometimes it will boot up fine and load up windows with no problems and work for some days before the problems start all over again.

specs are:

Win98
Athlon 1.3mhz
512mb pc133 sdram
40gb Fujitsu HDD
Soundblaster live soundcard
Geforce II mx 64mb graphics card
Network card
300w PSU

I built the system myself and as I said it had been running fine for months before the problems started.

Any help gratefully received.

Cheers

Zig

Sorry I posted this, it should have been a new thread which I will now do.

Apologies
