Un-Booting System there is power on the board but nothing seems to work as the screen does not display, the systems does not also send any beeping sign.

    I think it may be an overheating problem - which appears to be the norm for this make of computer;

    however, since i am abroad in northern Ghana - I can not guarantee getting to an HP repair workshop.... hence would also be grateful to hear if this problem might be able to be a straightforward one, eg: the computer just needs a rest and then may return normally later when switched on

    or whether to go through the long process, involving warrenty et al.

If the system is under warranty then call to nearby repair shop, as the steps given would cease the warranty.

1 Step:
You need to check out its Power unit (SMPS) placed at top in the CPU cabinet. May be it get worn out and need to replace.

2 Step: you can try is to Unplug the RAM (memory Stick) from the Slot and place it again after 10 min and then power on the machine.

Let me know the status after this to help you out. Don't vote till you get the solution.

Thanks,

    Overheating problem can be resolved, you can replace the Power supply unit and the cooling Fan of system, If you are able to install them yourself.

No signal on monitor, vga tested and ok


Did you check your monitor with other system or individually. If it works fine in these conditions then the issue belongs to your pc.
First of all, you have to confirm that is it the problem of VGA itself or the motherboard. For this, you have to see that does system beep when you start it because system with beeps having the error and the beep sound with continuous or 2-3 beeps relate with different issues. I am going to write down the beep conditions.

1 short beep Normal POST - system is ok 2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem 1 long, 1 short beep System board problem 1 long, 2 short beeps Display adapter problem (MDA, CGA) 1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 3 long beeps 3270 keyboard card

IF your systems turns on no beeps ...everything seems to work just no display on the screen then i guess would should try discharging your system - ie un plug the power cord take out the Motherboard ,ram , basically take everything apart leave it for a day and connect everything back again ti should work

Intellistation e pro acts as if booting, but doesn't


Its nothing but the port of your display cable in computer tower and the display card. If its inbuilt (on board) display card then the slot where the extention is linked. If you can then just open the tower and change the slot of the display card. 100% gurantee it would work.

Beep sound continus


I went to google and it seems like the beeps can be problems for different problems in the hardware, this is what one message says,  there are lots of computer beeping answers out there: 1 short beep is your BIOS saying "HELLO I'M OK" 

Standard Original IBM POST Error Codes 

1 short beep Normal POST - system is ok 
2 short beeps POST Error - error code shown on screen 
No beep Power supply or system board problem 
Continuous beep Power supply, system board, or keyboard problem 
Repeating short beeps Power supply or system board problem 
1 long, 1 short beep System board problem 
1 long, 2 short beeps Display adapter problem (MDA, CGA) 
1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 
3 long beeps keyboard card 

Each BIOS company has modified these codes over the years.

At POST I get 2 short beeps


it depends on the bios chip maker Here's some other beep codes:

for Award and Phoenix BIOS:

1 short beep: Normal
2 short beeps: CMOS error
1 long and 1 short beep: DRAM error
1 long and 2 short beeps: Video card error
1 long and 3 short beeps: Keyboard error
1 long and 9 short beeps: ROM error
Long continuous beeps: DRAM not installed correctly
Short continuous beeps: Bad power supply


AMI BIOS:

1 short beep: DRAM flash error
2 short beeps: DRAM ECC check error
3 short beeps: DRAM detect error
5 short beeps: CPU error
6 short beeps: Keyboard error
8 short beeps: Video card error
9 short beeps: ROM error
1 long and 3 short beeps: Bad DRAM
1 long and 8 short beeps: Video card error


Invoking Beep Codes

.

If the computer is actually functioning and the computer beeps continuously, then there is a problem with a voltage on the power supply being incorrect or the CPU overheating. IMMEDIATELY go into the BIOS and check CPU temperature, fan speed and voltages

**********************************************
BIOS Beep Codes

Annoying isn't it? You have built your computer you switch it on and then nothing happens except a few beeps from the PC speaker. Frustration sets in as you try to figure out what is wrong with it. If you didn't already know the computer has already told you the problem. It can't speak of course but it can direct you to the problem. Its all in the beeps. The BIOS can recognise when the problem occurs and sends a signal out to send a certain amount of beeps through the speaker. These beeps then tell you the location of the problem.

Unfortunately not all the BIOS' use the same codes as each other. Two of the main BIOS manufactures AMI and Award (now Phoenix) have different codes for there errors.

AMI BIOS

# of Beeps Error Description
1 Refresh Failure The memory refresh Circuitry is faulty
2 Parity Error Parity error in the Base (1st 64K) of memory
3 64K Base Memory Error Memory error in the base memory (1st 64K)
4 Timer Not Operational Timer 1 is not functioning (also caused by error in base memory)
5 Processor Error CPU error
6 8042 Gate A20 Failure Unable to switch to protected mode
7 Processor Exception Interrupt error The CPU on the CPU card generated an interrupt error
8 Display Memory Read/Write Error Video adapter is missing, incorrectly seated or has faulty memory
9 ROM checksum error The ROM checksum does not match that of the BIOS
10 Coms Shutdown Register Read/Write The shutdown register for coms RAM has failed
11 Cache Memory Bad The cache memory test has failed. Cache memory will be disabled. *** DO NOT enable it ***


With the first 3 beep codes, its well worth re-seating the memory just to make sure that it's in correctly. 8 Beeps is probably the most common in my experience. Can be caused by a badly seated Graphics card. If you have re-seated it then check with another Graphics card in the board.

Always check for loose components before sending the board back as this is the main cause of errors on the POST.



Award BIOS

Award states that they now only use one beep from there BIOS. This beep is one long beep and then two short beeps. This indicates a graphics card problem. Any other beeps should be treated as a RAM problem first and then the board sent in to be inspected.

The reason that the Award BIOS only uses the beep code for display problems is that it tries to display the error on-screen if at all possible. If the BIOS cannot initiate the display adapter then this causes the BIOS to make the beep code for a display error, which must be corrected before any other errors can be determined. Memory Test fails and hard disk failures etc will all be displayed on screen

IBM BIOS

The IBM BIOS works with Short and Long beeps as well as the Award BIOS. However the IBM one does still have codes to work from.

Beep Code Error
1 Short Beep Normal POST, System booted OK
2 Short Beeps POST Error - Code on Display
No Beep Power supply or Motherboard error
Continuous Beep Power supply or Motherboard error
Repeating short beeps Power supply or Motherboard error
1 short, 1 long beep System board error
1 long, 2 short beeps Display adapter error (MDA/CGA)
1 long, 3 short beeps Display adapter error (EGA/VGA)
3 long beeps 3270 keyboard card
Phoenix BIOS
The Phoenix BIOS works on a slightly more complicated manor than the others. It does display an error code for you and produce a series of beeps. This BIOS produces its beeps according to the hexadecimal code the error produces. The Phoenix BIOS has many different codes for its possible errors and so many different beep codes. Rather than list the entire section here, I have provided a link to the official PDF file containing the codes and how they are derived.

Phoenix BIOS Post Codes

System board errors should be looked at by a specialist, Again always try to re-seat components to ensure they are in correctly. If necessary take all components out except for the RAM CPU and graphics card, then try the system. Re-seating components is the number one fix for getting past the POST screen. One badly seated components can cause the entire system not to function. so pick out your bios and follow the steps above to diagnose .hope this helps
