This is almost certainly a bad power supply. (About 25% of pc problems I see with my repair business are power supply related). You can get one at any CompUSA, Bestbuy, etc. for under $30.00. Just simply install the new one the way the other came out. A 250 watt version should be fine, unless you've installed a video card then go with atleast 450 watts. Be careful removing/replacing the connectors so you don't bend any pins or crack the motherboard, but otherwise it's a very simple job (4 screws on back of pc holds it in!). Good Luck.

Pavilion s3620f has no video and won't boot


There could be many reasons for this. Open the case and make sure the components are plugged in tightly. Make sure the CPU Fan is spinning and is dust free.Reseat the RAM modules, make sure to clean the RAM slots before reseating the modules. If all this fails to give results, but a new power supply and try that, you do not have to install the power supply but can keep it outside and test it. If the MB is gone, then, look to see if she still has warranty, if not ebay may be a cheap answer for the same MB.

Any brand-new CD/DVD reader/writer with LightScribe *WILL* be compatible with your HP.
Check whether your "power" and "data" cables are the "old" style (white power connector and a 80-pin ribbon-cable) or the "new" style (thin SATA cables), before you buy a writer with the "wrong" (PATA versus SATA) interface.

Hp pavillion desktop will not power up. Blinking green light at power supply


Step 1 : Turn off the system by pressing the power button for 5 - 10 sec until the power LED is off. Removed all cables including the power cable (Exclude monitor cable and KeyBoard/Mouse).

Step 2 : Press power button for 5-10 sec again to drain fela power.

Step 3 : Reconnect the power cable at the back of the tower/computer and power on the system.

**If the same problem exists, Call HP tech Support (800-474-6836) because there is a high possibility that you have a bad Motherboard or Power Supply on the system.

Dvd/cd writer, and dvd rom drive does not work


Check if you have both cables attached to the CD/DVD drive. There are usually 2 that needs to be connected: the SATA or IDE (that ribbon-like connector that goes right to the motherboard), and the power supply (a connector that has 4 colored lines going to the power box). Make sure they are snug, and if necessary, try changing them with others that are known to work (there should be lots of spares). If the CD/DVD light blinks or powers on upon boot, it means power line is OK, but data cable connection is bad.
