My computer doesnt function right

Don't know this exact server. But my guess it is either a heat issue or a power supply issue. Turn it on with the cover off. Check the CPU fan(s). If your CPU is getting too hot the system might be shutting down power to save it. If everything seems cool it might be the power supply I have seen it when the power supply fan goes out on the power supply and the caps inside start to sizzle. Voltage ramps up and fail.
Hope this helps.
Also, Something that has tripped me in the past. Make sure the power button is not stuck. I had a server that the power button stuck down and it would turn itself off. Took me 2 CPU fans and a power supply to figure that out. LOL

From your description I would say they hard drive is failing and would suggest that you buy a new one and transfer all your data over to it or go to a pc place and have them do it.

If the system appears to power on, but you do not see anything on the screen, there are several methods to determine the problem at hand.

Make sure the cooling system is fucntional.. a bad CPU fan has been known to make the computer power on, but halt and do nothing to protect the CPU. Some CPU fan's have speed sensors, and other do not, some motherboards require the speed sensor to be functional, or resistance in the line.

Some mainboards will function enough to power the system up, but go no further due to onboad componant failures such as bad / broken SMR, SMC, or capacitor. If you are sure the mainboard works, and the monitor is known to function, proceed with the following troubleshooting tips.

1) Remove everything but the memory, GPU, CPU, and HDD, see if boot is successful, if not Step 2)

2) Replace the Power supply, under powered PSU's can make a system unresponsive / fail to make it to POST, if fails step 3)

3) Replace Memory, if fails, 4)

4) Replace GPU.. if fails, 5)

5) Replace CPU, a non-funtional CPU will alow everything to power up, but will not allow POST in some machines.

6) Replace Motherboard, if fails, start at step 1)

Once again , bad ram will prevent your computer from booting , make sure you are using a known good ram module.

hi, how is the heatsink compound between cpu? also check the bios, make sure it is set right, bus speed, ect. you can download it if you know the brand of mainboard. and the power supply could be on its way out. contact me for more help,if this info does not help. does it just die when on for a while? or when under load? isthe cpu fan woking ok? you can download speed fan free to see. good luck hope this helps,good luck!

i think there was a problem of virus, open in safe mode when its open then restore it for last known or when you start your computer press the F8 button then last known configuration if your porblem doesnt solve then reinstalled your windows

I habe exactly the same problem. I habe the P45 Neo3 Board with E8400 CPU and 4GB Dominator RAM(1066MHz). No signal aber reboot. A Bios-Reset helps vor a Moment, but after Restart, i habe no signal.

First It is not your monitor problem the problem is in your CPU

Open the Cabinet (CPU) door Took out RAM (Random Access Memory) after 5 miniuts Connect it

Thank U

Hi have you cleaned the heatsink? Also replace the paste on the CPU, also you could try installing an extra fan on the case to increase air flow. Also check that your RAM is seated properly and any other chip and card on your board is firmly plugged in. If all this fails replace your CPU. Regards mistyman

It sounds like your struggles may have damaged the motherboard. See other issues in this forum with this motherboard - partcularly with bowing of the board. Too much bowing can cause internal traces in the PCB to break. Only way to tell now is have it professionally looked at.
