First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

    They cut off half the problem. The machine powers up, I get no screen, no bios screen, no beeps, but the yellow Hard Disc light blinks twice in succession over and over. Fans power up, DVD rom blinks, I think it may be the CMOS board battery.

SOURCE: 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.

SOURCE: hp xw6200, 6 beeps, and red power button...failed start up.

6 long beeps indicates that there is a problem with the memory, take them out, clean the contacts and the DIMM slots and reseat them.
Hopefully this will resolve the problem, if not new memory may be required
kind regards

You need to have the Power Supply replaced on your Dell. Don't even think about repairing a power supply it caries dangerous voltages and you can get seriously injured. So just take the Dell to a Certified A + Technician Shop near where you live Local shops will often work with you if you do upgrades and repairs with them Good Luck! If you fel you can do this repair be sure to ground yourself so you dont short out your Motherboard components. and remove tyehb screws from the power supply and detach the power cables from the motherboard and hard drive and other drives optical drives CDRWs then replace and reconnect the new power supply dont buy the cheapest one getb a power supply rated higher than yoiur current one so that when you upgrade the system there is enough power there to run all the drives and devices. Good Luck Write me if you have questions I am a A+ Certified Technician with 14 years experience and I have a part time Computer Business. I had a Retail Computer Store and Repair business for over 8 years in St Petersburg ,Fl I do part-time repairs and upgrades now as well as new custom builds by request.

A couple of weeks ago, my HP Pavilion a706n was working completely fine. Soon enough, the first error appeared. I could use it for a good 5-10 minutes and it would shut off by itself. When I attempted to...


If you have cleaned out the dust with compressed air, then I suggest you look at the processor cooling. Is the fan running up to speed? Is the heat sink tightly in place on the processor? Feel the fins of the processor heat sink when you power it up and if they get hot your processor is most likely over heating and shutting down. If all is well at the processor, check the power supply fan to see if it is running and the only other suggestion is to try another power supply. Dust is your worst enemy in a computer.

Has there been a power surge meanwhile? If so, try unplugging the power cord, press the power button, reconnect power and try booting. Sometimes works.
