HP Pavilion a6042n won't boot past Blue HP invent screen

[cholernik]

I had this problem with a station at my work.  I unplugged the one thing that was hooked up via USB (speakers) and windows started normally.   I would highly suggest trying this before reinstalling windows or messing with BIOS--if you're even able try any of those options.

I had the same problem, got to the HP invent screen and then nothing, after several reboots....lot of beeps, more reboots and it booted. But after power down, same problem from the start.

Problem started after unplugging and replugging the main power cord. For some reason the BIOS did a reset and the PC tried to boot from the external drive. Unplugging the external USB drive and removing the external drive from the BIOS boot sector solved the problem. So my advice is to unplug everything (external drives, sd cards, USB sticks, etc.) except for keyboard, mouse and monitor and see if this solves the boot problem.

I have a Pavillion P6310Y that won't boot past the splash screen and also will not go into setup, bios, safe mode, recovery or anything else. I even sent for the recovery disks from HP and it won't boot up from those either. I can only hear the fans running but nothing else. Any ideas? I even went so far as to pull the CMOS battery for ten minutes and replace it and still nothing. Of course the warranty expired in November and now it's February.

Thanks,

Julie

Finally I fixed the problem of not able to pass the Blu Screen - one of my memory chips was loose!!

No problems since the fix.

Thanks to all for the help.

I have the same problem with my H8-12601. I have keyboard, mouse, printer and scanner plugged into my USB devices. If I unplug the printer the PC will boot. I shut off my automatic windows update to prevent coming in after Microsoft "Black Tuesday" updates to a dead computer. I've also experienced the scanner being intermittant if there are too many things on the USB. If I had to guess, the 5V USB on the power supply is weak and being swamped by the load of the peripherals. The 5V USB is typically derived from 5V standby, a critical voltage for the boot sequence. I may look though the BIOS for a setting on this, for now the fix is to unplug unused USB devices to boot and hope it doesn't get worse over time.

i Had the same problem with my HP pavilion a6604f. i changed to numorous hard drives still didn't fix it. What did fix it was when i unplugged all of the card readers and usb plugs from the motherboard.it booted right up try to unplug the wires coming from the front of the tower for the card reader.the plugs are plugged in the motherboard maybe 3 or 4 wires.
