PLease read my problem first and serious replies please only !!


Serious replies please !!!!!!

I am working on HP pavilion a000 desktop PC. OS: windows home edition

Problem : it shows HP invent welcome screen, it shows safe mode option screen and then all black screen. Nothing after that

Solution I tried already, please read it carefully before any reply
1) Hard disk is working okay, I have tried hard disk with another PC and its working fine
2) I have tried to remove all hardware one by one that includes CD-ROM , DVD ROM , card reader, RAM memories, All PCI cards and floppy drive. But even after removal still showing same problem
3) Only thing which I have?t tried is processor. Do you guys think I should try that one too.
4) Do you guys think if there is something wrong with motherboard and how can I check that.
Please note : booting is from Hard drive and its booting okay in another computer

Just curious to know what did I miss here. Please suggest me so we can fix this computer together.
Thanks in advance

How long have you had this machine?

The issue sounds like the usual dead motherboard, BIOS battery or CPU but as you know there are no diagnostics worth mentioning and why you swap those items to find out which one it is.

As always, do the use THE DEAD PC on google so we don't rediscuss how we start with almost nothing but cardboard, PSU and the speaker.

PS. Can't find a "a000" HP. Maybe you can supply a product link.

Replace the parts that don't work. In short, if the motherboard, cpu and speaker don't beep then you replace what you can and work up to the three parts that are needed for beeps.

Keep in mind that some wish there was a diagnostic to tell if it's the board or the CPU but today such a thing doesn't exist for a price less than that of a fine car.
