NO Post, Comp hangs at the HP welcome screen

October 19, 2011 at 09:30:32
Specs: windows vista
I have an HP Slimline 3713w that hangs on the HP welcome screen. NO Post, NO Beeps. My client told me the last thing done was transfer of pics from camera to PC. I have done the following:

Removed the connector from the multi-card reader device.

Removed hard drive, cd drive, pulled memory sticks. I did get a beep from the motherboard. (MB should be ok).

Replaced one of the memory sticks (still hangs at hp welcome screen)Tried each stick in each RAM socket

Reset Clear CMOS jumpers (no help)Also did a long reset leaving jumpers in clear position for 24 hrs.

reset clear bios password (No Help) knew it was a long shot but thought it might trigger me to get into bios.

Created a bootable thumb drive. Placed the files unzipped from HP's sp37379 on thumb drive as well as the self extracting sp37379.exe trying to flash the bios. Still hangs at the hp welcome screen.

This computer has a M2n61-ar motherboard but I cannot find the bios chip manufacturer from hp website or searching the web. I tried to read the chip itself but there is some sort of black marker across the top and down the side of the chip . I can only make out part of the writing.

I also wanted to note there is a ROM RECOVERY jumpers next to the bios chip, but cannot find any thing on the web about how to set the jumpers. I did pull the jumper from the original location and did,nt have any effect on the cpu starting.

Any ideas on what to try next?

New PSU?

My son's Packard Bell desktop PC had the same symptoms (no post beep, halted at splash-screen).

I fitted a new PSU and now it works fine. I didn't change anything else, just the PSU.

Hello Pip22,

Thanks for the reply, just got in and wanted to reply to your message.

I'm getting power to the CPU fan but will check the Power Supply in the morning. The power angle did make me think I should try and replace the CMOS battery as well. I checked the CMOS with a volt meter and was getting a 3.1v reading so I assumed it was fine and probably is, but you never know with these things!

Will reply in the morning with the results...Thanks Again

Pip22,

Just finished testing the power supply w/voltmeter, fan runs on power supply after shorting out pins 15 and 16, all the pins are putting out the proper voltage. Also replaced the cmos battery, still no luck.

I did not test the PSU under load as I have everything unhooked and just want to be able to get into bios to reset default settings.

Any other suggestions will be appreciated!

Thanks in advance to all who reply

PJG

If you can get into the BIOS, make sure the CD/DVD drive is first and try a Windows start up repair. If it boots to the repair, then hardware is probably OK and this should fix it.
If it can boot off CD, but repair cannot complete, run Memtest86 to test the memory, and hard drive utility from the hard drive mfg's website to test the hard drive.
OH! ** I just looked back and noticed you apparently cannot even get into the BIOS, so you probably cannot boot to CD either.....
Try it with the hard drive fully unplugged, if the drive is bad, sometimes it will prevent you from getting into the BIOS.
Try different memory.
Try a different power supply anyway (borrow from a confirmed working system).
If video card, try removing and use onboard video or a different card.

You have to be a little bit crazy to keep you from going insane.

Hey Fingers,

Appreciate the response. I've had the hard drive disconnected from the start, Just connected the cd-rom and created a bootable disk and put the bios files on it. Still no luck...

I've tested the power supply w a voltmeter and it is putting out the correct voltage on each connector. So I assumed it was OK. But you and PIP both have come up with the PS possibly being an issue. I am going to take the power supply unit and the memory chips down to Best Buy and have them test and check the status of the mem and ps. will post results late tonight or in morning.

Just tried flashing the bios again, this time from the cd rom. No luck.

I am afraid the bios may need to be re-programmed but if no one seems to know what bios chip is in this machine I'm not sure if it can be done. HP was zero help, kept wanting me to pay for tech support when all I needed was the damn part type and number. Asus, the manufacturer of the motherboard didn't even have this motherboard in their database. Aaarrrgg, the frustration!!
