first problem is i can't go in bios settings via f10. i can access bios menu by pressing <Esc> at boot up. but pressing F10 result to a blinking cursor at the top left of the monitor, and the system hangs then.
second problem is because of the above issue, i tried to upgrade to version 1.23 using HPQFlash but the flashing stop at
"Block 512 of 1024" and the system hangs.
My PC was purchase second hand. The model is HP Compaq dc7900 convertible minitower. I have search the internet for answers, but i have not found a solution to this.
Please help. Thank you.

the f10 key only works during startup, and if the previous flash stoped halfway you may now have a corupted bios.
try the flash from a USB Key (computers usb 2.0 port only, no addin usb card!!)
it is not recomended to flash within windows, use the DOS/USB Key method, or from within the Bios itself
Latest ME Firmware, download and read directions or you will brick the system!!!
ME Firmware Update and Utilities (bios must be updated first!)
NOTE: The Intel Active Management Technology (AMT) 5.2 ME firmware image is
only intended for the following:
-HP Compaq dc7900 PC
-HP Compaq 8000 Elite PC
-HP Compaq 8000f Elite USDT PC
-HP Compaq 8080 Elite CMT PC
-HP Compaq 6080 Pro
-HP Compaq 6000 Pro PC configurations
This SoftPaq does NOT include a system BIOS image. However, it is recommended
that the system BIOS be updated to the latest version before upgrading the ME
When the ME firmware is updated to this new image, it CANNOT be re-flashed to
an older ME AMT 5.0, 5.1, or 5.2 firmware version.
Several methods for updating the ME firmware may be chosen. Included in this
package are the following methods:
- The DOS utility updates the Intel ME firmware for the local machine in a DOS
environment, and also verifies that the firmware has been updated.
- The Microsoft Windows utility updates the Intel ME firmware of the local
machine in a Microsoft Windows environment, and also verifies that the firmware
has been updated.
Fix and enhancements:
- Adds CyberTrust Root Certificate hashes (GTE CyberTrust Global Root, Baltimore CyberTrust Root and Cybertrust Global Root) to AMT 5.2 firmware.
- Increases maximum Kerberos HTTP redirection ticket size to 10K (was 4K).

If you install the latest bios (1.23) it allready has the latest microcode included, there is no reasion to try installing the older (look at the dates!!) microcode update.
second the Bios utilities are not relevant, when all the user is doing is updating their bios locally.
while the help on this forum is appreciated, please try not just cut and past as this can cause problems for the person who posted the original request
last, my previous post had the bios and Me firmware SPxxxx updates so posting them again is not required

Thanks for your quick response.
i tried just now the DOS method with sp47156.exe, like before it does not flash, it completes the "Transferring System ROM...100%" but "Flashing System ROM...0%" remains as is.
I don't know if my thinking is right, since this PC was purchased second hand, it is possible to lock down BIOS so it can't

only thing i can think of is to reset cmos, and try again using the sp bios link i gave you
remove pwr cord, press pwr button for 10 sec
remove cmos battery, then press cmos reset button on MB if you have one for 5 sec
power back on, verify you can enter bios, then power off and reinstall cmos battery.
power on reset time date, and reboot
now try bios update.

I did the cmos reset procedure you gave and here are the result:
1. After cmos reset it did go boot up menu but pressing F10 its not responding.
2. I have to pull the AC cord to reboot again and it has to done multiple times until bios completes
auto configuration. I have to press F1 to save.
3. After about 5 reboots, pressing F10 goes to booting W7, date is weard 2029.
I have to try flashing again as instructed and i'll report the result.

again, F10 only works during startup, and the window for this keypress is very short (about 2/3 seconds max)
try powering on the system, then keep tapping the F10 key quickly as soon as the monitor light changes color, or comes on (or just do the tapping from power on)
also some usb keyboards have issues with entering the bios on startup due to the cheap usb controller board used on the keyboard if possible use a ps2 keyboard/mouse or a logitech usb kbd/mouse
