Hi, and welcome to the WTT forums
Sorry to hear about the BIOS problems…..
I did bios upgrade to v 3.17 please dont ask me why
1 I will have to ask you why you did this,? as its only necessary to flash (update) your BIOS if there is a serious problem that the updated BIOS is designed to fix, or an additional function that is very important to you is introduced by the new BIOS and you simply must have it…..otherwise a lot of experienced technicians would recommend that folks leave their BIOS well alone!
2 When you flash a BIOS, it can be a risky procedure…… if you get it wrong then your machine likely wont boot, as unfortunately you have found out
3 The BIOS that you updated to (V3.17) looks to be the BIOS for a different motherboard….. its confusing because your motherboard is a:
P5BW-LA
whilst the BIOS you updated to is for :
P5BW-LE (note the last character is E but on the one above its A ….
4 If you take your machine into a local computer repair shop they will probably recommend that the best repair is a new motherboard and this will be expensive……..
(the labour can be nearly 3 hours) + the cost of the new motherboard (and they are not cheap.)
5 If you contact HP they may say the same, but there is a chance they may re-progam the Eprom for you….(a thin chance but anything's possible) but do get a firm quotation before you agree to anything.
6 there is also a thin chance that a local competent computer technician will be able to either reprogram the Eprom or replace the BIOS chip on the motherboard, or has the skill and experience to make a crisis disc, find the original BIOS files (from HP) and undo what you have done……
Please be aware that the process in 6 above is technically quite challenging and time consuming, and generally its financially uneconomic to do it…..
7 You could try to do the work yourself if you like researching and trying to find the original BIOS files but see my remarks above about technically challenging and time consuming work.
If you want to try it yourself then you can make a start by going here:

8 The cost of new computers has fallen recently..would it be worth you considering buying a new one?
9 One final thought if you can get into the BIOS setup screen then you could try resetting BIOS to default /safe/conservative, saving the changes and seeing if the machine will reboot….. there is a 1% chance that it will….. but its worth a try!
Having considered all the above I'd recommend you contact HP or their accredited service agent in your locality, as a first step……..this is particularly important if the machine is covered by a service agreement
Sorry to be the bearer of bad news.
