WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the memory modules from their slots. Take the opportunity to clean the slots on the motherboards and the memory module connectors. Use compressed air to blow dust away and clean contacts with a soft cloth. Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components. Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r Allow the pins to dry. They will air dry in a matter of minutes. If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer. Check the memory module and memory slot contacts. They are either copper tin or gold. The colour will tell you which they are. Mixing tin and gold can result in corrosion that prevents proper contact. Look for any sign of physical damage to the memory module, memory slots or the motherboard. Reseat the memory modules. You should hear an audible click when they are in place. Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard. The hardware that you are trying to access is damaged or failing.


The device drivers for the hardware are faulty or incompatible. Could be a problem with the Hard Drive or the Hard drives PCB http://www.onepcbsolution.com/ There is a connection problem such as a bad cable for internal hard drives
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your MOTHERBOARD TO THE 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 flat 40pin ide this will be the first to fail Make sure all leads that are attached to your drives dvd\cd and floppy (If Applicable) have secure connections and are not faulty. or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error

Hope this helps.

SOURCE: my HP a250n boots up to the windows logo, then

Sounds like your windows installation was corrupted. Try booting into safe mode from BIOS. If that doesn't work you will need to re-install Windows.

Check you are fitting the same specification of RAM into the expansion slots as you have in the others. To make doubly sure fit the same make and size, this will swerve any compatibility problems.

I have a a1630n and suddenly when I turn it on, the fans run fast and screen stays black. No beep. let it sit over night and on the first boot up the screen will go to the windows xp logo and than go...


Alot of problems with the HP.

First thing is make sure when you changed the battery you would need to check the jumper that allows you reset the BIOS and let you use the computer.

The other is the fan speeds it normally should go a little high not so high but in your case the CMOS battery that was installed could cause some things not to work especially if it supports PCI-E. The motherboard in your system must have a dual video connector. One is on the board and one is on the PCI-E. Make sure the monitor is plugged into the right port. It should work after that. If not remove the PCI-E card and see if it works with the onboard connector.

My 2 speed jandy pool pump is over heating


you may either have a bad start/run capacitor for the high speed side or bad supply voltage feeding the high speed side. If there are no loud bearing noises, it should just be either of those two problems.
