Computer intermittently won't boot, no beep

[adams67]

Hi,

My computer won't start up. When I press the power button the lights all come on, the Hard Drives spin up the CPU fan starts spinning but the computer won't do its beep and nothing will come up on screen.

I can sometimes get it to work by trying over and over and over it will sometimes eventually beep.

This may take one attempt or dozens with no sucess.

I seem to have the greatest sucess at night time when it will usually start after no more than 5 attempts.

Once it is on there it has no problems, I can restart it as well (e.g. from the bios- save and restart)

I thought it was the powersuply so I replaced that, I think it might have started working better but I might be just crazy.

I don't get any beeps when I remove all the hard drives, the Video card, and the RAM

Or if I remove any one or two of these things, still no beep

I've tried reseating everything including all cables

I've taken out the CMOS battery and then put it back in.

This is what I'm using:
Antec TX1050B File Server Case
Antec ATX TruePower 650W
Asus P5B-Deluxe-WIFI 775, CORE2EE, P965, 1066FSB, PCIEI6, AUDIO, GbLAN
Intel ATX E6600 CORE 2 DUO /2.4GHz/4MB CACHE/1066FSB/LGA775
Zalman CNPS7700-Cu Cooler
Kingston DDR2 4096MB(4x1G)PC6400 800Mhz
Gecube Radeon X1950XTX 512MB Dual DVI GDDR4
Maxtor DiamondMax 320G SATAII (16MB cache)
Western Digital 500G SATAII 7200 rpm HDD(16Mb Cache)
Samsung 750G 7200RPM 32MB Cache SATA II

Thank you very very mcuh to anyone who can helpTV

Next time you try to boot up and it fails insert the windows OS disc and then reboot and see if it will boot from that without any problems. If it does then run the manufacturer's diagnostics on the hard drive as it may be failing.

Identify the make of your hard drive and then use one of the links below to get the manufacturers diagnostic for ISO CD. Burn the image file to a CD, boot the PC with the disc in the drive and run the diagnostics. You first need to set the CD drive to 1st in the boot order in the Bios setup.

If you do not have an image burner use this free software to make the CD.

Please provide the model number of your drive if it is Toshiba Fujitsu for further instructions, this does not run on Windows 7. I would suggest the use of the diagnostics from the Seagate link as this will work on all makes of drive and on any OS.

I don't have a CD rom drive, I'll try booting from a flash drive or something.

I can't even get into the BIOS though when it's having it's problems though

No CD drive, how did you install Windows and all your software?

CD drives are very cheap these days and come in handy especially under these circumstances.

Alternatively you could take the hard drive out and hook it up to another PC with a USB adapter and run the diagnostics from Windows.
