HP boots to BIOS screen then stopped working

Hewlett-packard / A6642p

Specs: Windows Vista
One evening after surfing the internet I
shutdown my desktop in a normal fashion.
The next day I turned it on and it got stuck at
the splash screen. That's it. It sits at the HP
(boot) splash screen with the F10=setup,
F11=system recovery, F9=diagnostics
Esc=boot menu options to choose from. But
none of them work. If you hit one of these
keys it will say that its running and then that's
it. It just sits there, running forever as far as I know but I turned it off after a few hours.

All the fans are running but nothing else boots up, no hard drive, no disk drives.
I did not recently modify this computer in any way whatsoever. The only thing I did do was install a trial version of ZoneAlarm Internet Security Suites to the PC after my Norton subscription had expired - 2 weeks prior to this incident.

I've tried the basic dust removal, cleanup on
the inside of case - no change. I have also
unplugged all external devices to see if one is
defective - no change.

I purchased this computer 14 months ago so it is out of warranty and I have yet to contact HP directly.

Any ideas on what to try next?

Hello, I just had a similar problem, a customer brought me a HP s7520 and as soon as you turn it on it froze at the HP INVENT Bios splash screen, now of coarse after swapping ram, hard drive, all pci devices, and cmos battery i figured at least one of the swaps would solve the problem but didnt, now the operating system work completely flawless but or coarse i would have to unplugg the desktop like several times before i could get pass the splash screen, and as soon as i was going to recommend to the customer that they needed a new motherboard i inspected the front panel that had a damaged usb post and memory card reader, i unplugged that and the problem got better but still existed, then i looked at the board one more time and found a very small wireless adapter that was obviously not in use, as soon as i pulled the plugg on that sucker i had no more problems, moral of the story is that computers can be funny like that sometimes its the less obvious and sometimes its something that you didnt even know was connected, first test the obvious hard ware and then start checkn odd ball components such us front/side/bottom ports and such and i am sure you will find your problem, sometimes if you can manage getting into bios try the diagnotic screen mode at start up, its the alternative screen you can pick for bios startup, rather then your manufacturer's screen splashing at startup its the screen that shows your ram count and devices bein loaded
