Check to ensure you Video Card (and all other cards) are seated correctly in the slots. You may have knocked it loose when changing your drive.

Dell wont boot when pluged in it comes up for split second and shuts down green light on motherboard is lit



Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

Test all power and data leads that attach to your hard drive IDE,SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

if its a 40 pin flat ribbon type it will be the fist to fail
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be

faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty power lead can cause you problems

computers need power and data travel through every working device and to have an end to be able work properly


make sure ram modules and cmos batteries have dust free secure seatings and cmos battery has charge some motherboards cmos batteries are soldered in


motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail


check all power and data leads make sure they have secure dust free connections

cd/dvd floppy drives need to have current go through make sure these drives are working


check you CPU make sure its securely seated and has thermal grease

hope this helps

My hard drive clicks and the moniter turns off


Hi, you can isolate that problem to see what is the defective part;
1. Remove the hard disk connection from the board and its power then re-start the PC.
2. If the PC powers and initializes, then you can prove that the defective is the hard drive. If the same problem that it shuts down then. the next target is the power supply. If you change the power supply and it turns out success, then we have solved the problem, if not, next thing is,
3. Turn off PC, remove the battery/clear cmos, the memory and the processor for 20 minutes.
4, After 20 min re-install the battery, memory and processor. Without the hard drive when starting, lets see if it will boot without the O/S.

others, when you say the monitor turns off, does the CPU still working or not? Isolate also the monitor by powering it on and not attaching the communication cable to video port, lets see it the monitor itsel display by its internal video logo to be sure it is okay.

Moniter shuts down while playing wow while not in windows mode


Go to your computer's Control Panel, Power properties, and change the power scheme to Always On, where hard disk shutdown, monitor turn off and system suspend are all set to "never". This should help.

Problem for Acer Aspire 5315 PC Notebook. This notebook will power up but nothing is happening on the moniter and even on a external moniter. I cannot tell if it is even booting as the hard drive light or...


have it check with the service center, the problem is no in your hard drive, or ram. or even your monitor, it has something to do with your video card, and you'll need to take out all to cover to get access to it, so I suggest better bring it to a service center to avoid more damaged
