Typically the problem your describing is found in the power supply.
You will need to replace the power supply with the same watt rating and compatibility as your PC.
Just to confirm that is the issue, I would disconnect all attached interface cards and drives from the motherboard..with the power supply being the only attached item.
Power up the PC, if it stays on.. the power supply is good.
You will then install each component one at a time and restart.
You will identify the bad component when the problem comes back.
Make sure to disconnect the power cord each time you remove and install each component. Never plug any component into the motherboard while the power supply is connect to power.

My dell moniter shows purple light at the power button instead of blue/orange.... and its not workin.. wat could be the problem

First of all you need to check you keyboard light it may be the issue with your CPU. So check you keyboard light and press Num lock key if it's getting on/off when you are pressing the key. If it's working or not. It must be blink when you press the num key. If it's constent or not getting on then check with you CPU first ....may be there is some issue with you CPU. Second you can remove the cable from CPU which is connecting to monitor to check ....when you remove it from cpu it will give you some message on the monitor screen that check you vga cable etc. If it give's such message then it will be for sure then you need to your CPU fixed up.
So please comment back with your troubleshooting details , hope it will help out you.
Thanks Sanjay Kumar

Error lost cpu rest

This error on the T6125 may be caused by either a hardware fault with the printer, alternatively the problem may be caused by some sort of external influence on the printer. Passable resolution to the problem include;

Hardware Fault

Locate the main logic board, check the CPU to ensure all pins are soldered correctly on the PCB. Check there is no solder over spill shorting any of the pins.
There may be a fault with the main logic board which may require replacement.

External Influence

1) External Print Server

One of the most common causes for the LOST CPU error is the use of external print servers connected to the Parallel Interface.
These printers are not reliable if connected to external print servers unless the printer parallel interface has been set Uni-Directional. To do this, you need to follow these instructions.
Set the printer to Offline.
Press the Enter and LF keys together for approx 3 - 4 seconds. The alarm will sound. (Tech Access On)
Press the Mode key: display will show Offline Normal.
Press any Arrow key until display shows Offline Config.
Press the Forms/1 key.
Press any Arrow key until display shows Config Parallel.
Press the CPI/2 key.
Press any Arrow key until display shows Parallel Bi-Dir.
Press the LPI/3 key.
Press any Arrow key until display shows Bi-Dir Off.
Press the Enter key and the interface will be set.
Press the Clear key.
Press the Enter and LF keys together for approx 3 - 4 seconds. The alarm will sound. (Tech Access Off)
On the external Print Server, you need to ensure that the unit is also set for Uni-directional working.

Electrical Interference

Check the area around the printer to ensure there is no external electrical interference eg Electric Motors, High Voltage Cables in near vicinity of the printer.

How do I fix my computer moniter?the screen is black

When you power up then after 12 seconds check the num lock led status on key board press num lock key then if num lock led is on and off then your cpu is working fine.
For that make sure vga adapter from monitor is connecxted to cpu is properly.Then when you power up the computer press F8 key then you can see some menu enter in "Enable vga mode " then go to display property and change screen resolution to 1024*768 then apply and check.
But if num lock led is constant then then you need to open cpu cabinet cover.
Then reconnect ram memory .Try it in different ram slot.Make sure motherboard is not ground with cabinet.REmove pci or other card if any.
Then check.
Pull cmos cell from motherboard for 10 minutes then connect again.
Also reconnect processor and it's fan then check.
Let me know if you need further assistance.
