Nothing on the monitor, the computer powers up and e machine f2 comes up on the screen then goes blank


hello bradprice258

I am assuming you have an LCD monitor

when the computer turns on look carefully at the front face of you computer case, there are two small LED lights. one is power and one is hard disk activity.

look at the one for hard disk activity. watch it for a few mintues, if it is activly blinking and then turns off or becomes a random blink then it means the possibility is a faulty monitor. LCD monitors do that once they age or get hit by power surges or black outs.

if both lights in front of the case go out as you loose display then the problem is with Po itself. could be bad power supply of main board.

hope this has been of help.
please do leave comment if this has helped.

Older Dell 8200 will not power on. When plugged in the power light blinks amber, and it will not respond to the power switch. If I swap out the cpu for an extra celeron I have lying around the fans power...


To better troubleshoot your issue take a look at the 4 diagnostic lights on the back of your PC, they will give you more information and possible solutions. HERE is the link to what the lights mean on your model PC.
Diagnostic Codes Your computer is equipped with four diagnostic lights, which are labeled "A," "B," "C," and "D" on the back of the computer. Each of the four lights can be yellow, green, or off as shown in the following table. When the computer is turned on or restarted and it is functioning normally, the lights flash during POST. After the computer starts, the lights remain green to signify normal computer operation.
If a malfunction is detected and the computer fails to start, the lights display a code that identifies the problem. Write down the diagnostic code displayed and look it up in the following table.

I have a hp a350 cpu.the problem is that the light of led has gone red,as before in working condition it was green. It can't start.the power to hardisk is also not coming.please tell a sollution.


As you say has become red and no power to the hard disk.
First check the power cable for any loose connections and check if it give power to the cpu and the fan placed on processor starts working as you start the power. If fan it starts and with in few seconds stops then your power supply/SMPS is weak or damage. So replace it for proper working of your computer. And if after power on all fines but red led on monitor and no power to hard disk Try to replace the hard disk power cables because they are not working because of it no operating system is detected and led of monitor is red. After replacing hard disk cables hard disk starts working and still no display or red led on monitor check the vga cable for loose connection or replace it.If you are using vga display from graphic card try to get display first from onboard vga slot.After it your problem will disappear and your pc run smooth and fine.

Started blinking on off after standby. Restarted cpu it worked fine di the same thing after standby again now it lashes on/off even when the cpu is off


1 •Click on the Windows Start menu and go to Control Panel.
•Step 2
Click the "Power Options" choice located inside Windows Control Panel. The choices are listed in alphabetical order. A photo example of this
button is located within this article.
•Step 3
Power Options Properties Dialog Box in Microsoft WindowsClick on the first drop down box, which displays "portable" or "desktop" types of
power scheme choices. Select the one that best suits your computer use even if it is not a desktop or laptop. Doing this will not adversely affect
your computer.
•Step 4
Turn off monitor time options example menuClick on the "Turn Off Monitor" options and select your desired time limit from the drop down box.
You can feel free to select "never" for this choice and any of the others. One column displays "Running on Batteries" while the other displays
"plugged in options." Your selections can be different for each. Make your choices according to your use and preferences of your own
computer. A photo example is shown within this article.
•Step 5
Turn off Hard disks exampleClick the "Turn off Hard Disks" choice if you would like to change the timing of that.
•Step 6
System Standby choicesClick on "System Standby" and make any changes to the time limits as needed. This is optional. It may be best to select
"never" or at least a few hours for this choice.
•Step 7
System HibernateClick "System Hibernates" if you wish to have your computer hibernate (or "sleep") after a certain length of time. This again is
entirely optional and not required. When you are finished, click "OK" to save all of your choices. This is very important.

2 light is lit on front of cpu


That's not a problem. One light(Green one) is for power and another (Red one) is for Hard Disk. Red one will blink continuously, if hard disk is being accessed.

I have sys which contain main board marrcury(p1865d7).now i will run visual studio2008 but not properly run so plz give suggetion @ processor & ram


According to Microsoft: Minimum: 1.6 GHz CPU, 384 MB RAM, 1024x768 display, 5400 RPM hard disk Recommended: 2.2 GHz or higher CPU, 1024 MB or more RAM, 1280x1024 display, 7200 RPM or higher hard disk
I know that Visual Studio 2008 runs fairly slowly on a 2.4GHz laptop with 1GB RAM, so I can't imagine that it would run all that well on a 1.6GHz machine.

Computer will reboot on Virus/Spyware scan at random. I have: 1. Installed clean XP SP2 parallel system and booted that one. Same problem. 2. Memory Test at boot time is OK. 3. Air circulation from Power...


The weak airflow from the power supply unit (PSU) is suspect. Virus / Malware scanning is a disk and processor intensive operation - resulting in greater load on both. Increased load translates to heat. Check to be sure that the processor (CPU) fan is running, too. An overheating PSU and CPU can cause all types of problems.

Are you using a genuine XP install disk/image or a disk of questionable origin? Use of bogus OS disks is "asking for trouble".

If your system BIOS or set up (accessed during boot) allows, try to located the page that displays component temperatures and fan speeds. Check this immediately after rebooting from a an unplanned shut down - if unable to locate this set up page, download HWMonitor at:

http://www.cpuid.com/hwmonitor.php

It is a free program - choose the 32 or 64 bit version. Note fan RPM and CPU core temps to help determine where heat is coming from - or which fans aren't operating correctly.

Yellow blinking light and no power


You did not specify the brand but I assume it's a Dell and no beeps are heard, no CPU fan is turning on, only blinking yellow light. This brand usually experiences this problem.
  1. First, check the power supply. Disconnect connectors from the board and make a jumper wire for the green wire to any black wire. If the PS fan does not spin then it's busted, else proceed below.
  2. Reconnect connectors except the one with 4 wires, 2 yellow and 2 black, then switch on. If CPU fan turns on then you have a bad processor.
  3. If the fan is still not turning on then check the USB port pins for short circuit.. disconnect it from the board and switch on.
  4. Do the same with other hardware connected to the board.
PS: The metallic casing of computers must be connected to the common ground of the power utility to protect it from stray currents that result to damage of sensitive components such as processors, memory and hard disks.

No display and wont boot


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Power supply is easier and cheaper to replace.

Power lite blinking


The power light stays on when you start a computer. If it is the hard disk that works, it blinks once in a while. There may be a misconnection of the wires in the front panel of your desktop. You can check by seeing to it that the wires match those in the mainboard of your computer. Consult your computer mainboard manual for the location of the corresponding terminals for your front wires (e.g. hard disk wire into the corresponding hard disk terminal in the mainboard).
