New system start-up problem.

By J_R_M ·
Hi There, I have just assembled a new PC and cannot get it to BOOT or POST. No display visible, monitor LED is still orange (no signal) and no beep code sound either. Just a blank screen and no signal evident. Fans all work and on-board LEDs are on. Graphics display says no VGA cable detected. (I've tried 2 monitors LCD & CRT...both work on other PC.) I have also cleared the Bios (jumper method) as a last resort.

SYSTEM SPECIFICATIONS:
Case & Power supply: Antec P193 + CP-850 PSU.
Motherboard: ASUS M4A79T Deluxe
Processor: AMD PHENOM II X4 955 BE (Box)
Graphics card: ASUS EAH4890 1GB
Memory: 4GB. Corsair TW3X4G1600C9DHX
HD Western digital RE3 WD5002ABYS
Optical (dvd, cd blu-ray): LG GGC-H20L
Floppy: Sony 1.4

I am at a loss to why it will not boot. The above specs are all quality parts. I've checked cables PSU etc. I suspect it may be the Processor is too new for the motherboard bios as mentioned in other forums. However, some have managed but most like me have not.

Some say to get a new BIOS chip with the updated driver etc. (since you can't boot and flash it anyway) I may even purchase a Diagnosic (P.O.S.T.) card.

Any clues please? All suggestions welcomed.
Many thanks in advance,
Jeff

Isolation test

by BizIntelligence In reply to New system start-up probl ...

You will need do a isolation test:

First of all, make sure all the cables from PSU and case (speaker, power, LEDS)are correctly connected to motherboard.

1 > disconnect HDD, Disaply Card, Floppy and optical drive. try now ...check for beeps
2 > with all above things disconnected try using one stick RAM (depends on RAM) at a time. try now...check for beeps
3 > with all above things disconnected at step 1 take the motherboard out of the case (put it on cardboard or anti-static bag) and then check for beeps.

If all of them fails then motherboard or CPU is faulty

Check CPU and RAM in other PC.

Cheers !

Before you do the Isolation test

First thing to try is loosening the Screws that hold the Motherboard to the Case. They will only need a full turn. Reconnect the Power and turn it on. If it powers up shut it down and retighten the screws. They only need to be firm.

Yes, I tried that before posting to this site neglected to mentioned it for brevity. Have ordered a Diagnostic POST card.
Will keep you all posted (no pun) on the results in a week's time.
Thanks for you reply.

Could be catch 22

by Jacky Howe In reply to RE Test

If this is your CPU Phenom IIX4 955 (HDZ955FBK4DGI),3.2GHz,125W,rev.C2,SocketAM3,Quad-Core

http://support.asus.com.tw/cpusupport/cpusupport.aspx?model=M4A79T%20Deluxe

If your motherboard BIOS version number is greater than the BIOS version listed above, then you will not need to flash your BIOS. However, if your BIOS version is smaller than the version listed above, then you will need to select and download the latest BIOS to update your system.

Re: Catch 22

by J_R_M In reply to Could be catch 22

Sure is catch 22...you're spot on.

The thing won't boot to get the BIOS version anyway.

I have ordered a POST card just to make sure it's not something else. If it is the BIOS I have three options..(A) get a new updated chip. (B) take the board to some one to flash/update it and (C) Buy/borrow another AM3 CPU of lower spec, flash the BIOS with the updated driver and replace CPU with the 955BE I have on hand.
Crazy eh?

Good thing I am patient and take this as a great learning experience.

Many thanks for your reply.
Cheers,
Jeff.

I don't know

by Jacky Howe In reply to Re: Catch 22

what you have access to in your area. It looks like you would have to travel a long way to a City. (B) and (C) would be the way to go if you can find someone to help out. Good luck in your adventures.

Thanks for your good wishes Jacky.

Yes, I'm a long way from most cities. Postal and courier service is good these days. Cheaper than driving etc.

Also make sure that

by OH Smeg In reply to New system start-up probl ...

You have plugged in the Supplementary 12 V DC Plugs to the M'Board. You need to connect the 24 Pin ATX and the 4 6 or 8 Pin 12 V DC plug tot he M'Board. :0

Also if the Video Card has a Power Plug on it this need to be plugged into the PS.

If none of the above make any difference remove and correctly fit the CPU.

Also according to ASUS this M'Board doesn't support this AMD CPU till BIOS Version 0902
see here on the ASUS Web Site CPU Support List for this M'Board.

You can get the new BIOS Code from here

Though you will need a different CPU to load it. If that is the case the easiest and best way to proceed is to buy a replacement BIOS Chip from a place like Bios Man here

http://www.biosman.com/

I have purchased numerous replacement BIOS Chips for Servers over the years from this company and never had an issue with them.

Re: Making sure....

by J_R_M In reply to Also make sure that

Thank you for your detailed reply...great stuff. I've already done most of what you've suggested. But your biosman.com link will prove very handy after I receive my P.O.S.T. diagnostic card next week. I will keep you and other repliers up to speed once diagnostic tests are completed.
Thanks again.

NEW BIOS Chip

by J_R_M In reply to Also make sure that

Hello again,

Got a new BIOS chip from Mr Lee online store in the Netherlands. Biosman does not carry the modern 8 pin BIOS.

See my final posting....Problem solved.
