Good luck with that. Why would you want a 23 year old CRT when there are Ultra HD flat widescreen monitors available. Even if you could find on in working order, it is likely to fail in the very near future.

Start your web browser,
find options, open options.
Find and open search.
On this page you will see
"Use the address bar for search and navigation"
and
"Add search bar in toolbar"
which puts a separate window next to the address bar with search written in it..
Choose which one you want to use
Go down to one click search engines.
You will see a number of search engines in a box usually ticked.
I use a search engine called Duckduckgo because it does not keep any data on me...
under the search engines box there is a line in blue "Find more search engines".
Click on the blue line and you will see a list of different search engines, click on one and a new page will open up and you follow instructions to install the search engine.

In she search engine box, if you do not want use one of engines just un-tick it

Hope this helps
Regards
Geoff

There are a number of reasons why a computer will bluescreen. You'll likely need to take the unit in to a qualified technician to get it fixed.

57-100 57-200, 57-300 or 400? there are 4 versions.
to what device? unstated and matters big time. BT head phones?
first is , it must have Bluetooth, most didn't then.
it was an option, then. (in fact many options)
most times its part of the wifi card inside.(and was)
or it did work before today (I lost)? means that?
then the HP Compaq driver is missing for it.
HP has it , if you download it.

the #1 cause of Bluetooth software driver failure is upgrading the unstated OS and there is no driver for that OS. (w7 to 10?)
what OS does your 57 run?
it came with windows 7, is that it?
the 57-100 PC has this driver.(Wild guess, no PC full P/N stated)
worse yet they offered 2 BT cards seen here(network drivers)
(what I do , lacking hwINFO32.exe is look at the card first.
see what is there. make and model. the pick the driver.

you lost the case to it, it was , or buy ***** motherboard?
- Compaq Presario SR5130NX !!! 12 years old I think. 2007
what are you doing , ?
why need any RS232 COM1 port or relic LPT 25pin port
can you tell why first? and this does not exist here.
(sure with add-in cards or USB dongles on any PC)

that PC is old, Compaq ran for many years and HP killed it 2013. ONLY HP.com support it today, ok?
I see you reading the mobo numbers top center
desktop OLD. and top CPU is.
Core 2 Duo E4x00 with Dual Core technology (Conroe) up to E4400
relic.
2GB max ram. total.
gma950. no intel support now.

why think this card mobo has COM1 port, there is none
nor LPT line printer port, for years.

HP ended support on the PC long ago.
all they have is , echo of past , light.

Firstly enter the bios screen and set your boot device from HD to USB. Insert your bootable USB drive and start the machine.

I am pretty sure you can't boot an OS from a USB. Burn the install media to a disc or put it on a spare partition. USB boot is for anti-virus or PC Diagnostic Tools.

That sounds like your hard drive may be dead...

Compaq Computers... | 42 views | 0 helpful votes


If you are more than just a beginner you can attach that drive to your PC and run a drive copy program that will create an exact image of your current drive. Once that is created then you can add the new drive to the computer make sure your system recognizes it and can boot from it. I have done this many times.

older Compaq day, wow.
the C57 has many numbers in suffix, 57 is not just one PC. ok.

or google that code.

so you did not tell the story, you push the power button
with main battery removed, (big bat out ,yah they SHORT)

3: bios hot keys dead.
4: Bios screens dead.?
5: windows login screen missing? if it is even windows at all?

On that model,there are a few things that can cause your problem.None are simple and the most common is the GPU (video chip) has lost contact due to over heating.
The cost of repairing it, if you could find someone willing ,Would be way more than one that old is worth.
