What would cause a Dell Inspiron 580 that powers on but display nothing on the screen?

Some types of memory will only work as matched pairs, try only using two sticks of the same type, Otherwise check your memory and graphics card are seated properly, remove the power cable to the monitor for a few minutes then plug in, check you haven't loosened the monitor cable. Do you get anything onscreen? if you get start up then check BIOS see what memory it reports & the graphics settings. Its most likely something loose or the memory.

Dear PC Experts, I have a computer HP Pavilion m9300t and have been using three years already. The problem occurs about 4 months ago. When I turned on my computer, it looks fine in the beginning. As I...

It's probably the graphics card. They are one of the most common items to go bad over time. You could try to open your computer and blow out the dust from the video card, the CPU, the Fans, the Power Supply, and any other area you see dust collecting. You'll want to unplug the unit and take it outside to do this. Also, if you have more than one port on the back that will take the monitor cable, try plugging the monitor into that to see if that works. (some machines have a video card in a PCI slot as well as a built in video port... if the PCI card is bad, the built in port could still work).

I have a standard hp desktop which world of warcraft can no longer run on it. ( inadequate memory per the patch update from WOW) I am going to purchase a used pavilion 523 desktp 80gb 512mb but was told...

System specifications for a Pavilion 523n desktop computer are;

1) Processor: AMD Athlon XP 2200+
1.8GigaHertz maximum operating frequency rate.
266MegaHertz Front Side Bus
(266MHz FSB)

WoW minimum system requirements:
Intel Pentium 4 at 1.3GHz, or AMD Athlon 1500+, at least.

Good to go.

2) Ram Memory:
512MB's of DDR Sdram ram memory.

WoW minimum system requirements:

Barely good to go IMHO.
You need 1GB, and 2GB will make it right.
The max is 2GB for the computer.

Graphics/Video Card:
WoW minimum system requirements indicate it doesn't take poddy for a graphics card to run it.
Maybe more for the Wrath of the Lich King, of course.

The motherboard used is made by FIC.
First International Computer { Inc }
The Model Number is AM35

The graphics (Video) expansion slot on the 523n's motherboard, is an AGP expansion slot.

It is an AGP 2X/4X slot.
Use a graphics card that is 4X or is 4X/8X compatible.




The difference is the technology that has evolved for the Accelerated Graphics Port through the years.
First there was 1X, then 2X, then 4X, finally 8X.
Graphics technology has moved on to the PCI Express expansion slot now.

The different AGP expansion slots are keyed differently from each other, for one.
For two they use different voltages.

An AGP 4X slot uses 1.5 Volts, whereas an AGP 8X slot uses .08 Volts.
A graphics (Video) card that is 4X/8X, will adjust when used in a AGP 4X slot.

(P.S., that Pavilion 523n uses a 200 Watt Power Supply. At least that's what the Maximum Wattage rating was, from the power supply manufacturer who sold it to HP.

Actual is more like 60 percent of what is stated.
120 Watts.
You really should go to 300 Watts, or 400 Watts.

(A computer ONLY uses the power it needs, and NO more.
Won't hurt the computer.
Also won't kill your electric bill when you're not gaming.
Gaming? Eh!)

It's an ATX (Form factor) power supply, but the case is shallow.
The ATX form factor relating to a Power Supply denotes the size, and shape of the power supply's case.
6 inches Long, 5.5 inches Wide, and 3-1/2 inches tall for ATX.

The one in the Pavilion 523n is 6 inches Wide, and 3-1/2 inches Tall, but it is only 4 inches Long.

When memory check starts, get a + then hangs

Computer unplugged from power, computer case open, observe Anti-Static precautions, then remove the ram memory module/s.

(Slang for ram memory module, is ram memory 'stick')

Use a pencil eraser, and clean the gold plated contact pins, on the bottom of the ram memory module.

Just rub the eraser on the contact pins.
(If the eraser on the end of the pencil is attached by a metal sleeve, refrain from letting the metal sleeve touch the contact pin/s)

When handling the ram memory module, refrain from touching the contact pins on the bottom.
You can handle the ram memory module anywhere else, as the body is coated with a see-through protective plastic.

Lay the module on a wood table, or other non-Static surface when cleaning.
Example of a DDR Sdram ram memory module as used in a Pavilion 523n,

Use air to remove the eraser dust.
(You can use a can of compressed air for computers, or air pressure from your mouth is sufficient)

Reinsert the ram memory module/s. Close the computer case, plug back into power. Wait 1 minute, turn the computer on.

[Anti-Static Precautions:

Your body carries Static electricity.
Static WILL fry out (Short Circuit) the hardware components inside a computer.

Working on a table, computer unplugged from power, computer case open, TOUCH the metal frame of the computer case (Unpainted surface) to relieve your body of Static.

Should you get up, and walk away in the middle of working on your computer, upon your return Touch the metal frame again ]

Opening your computer case.
Looking at the Back of the computer, there are two screws on the far right edge.
One above, one below.

Remove the two screws, slide the side panel back about 1 inch, tilt the side cover top to the outside, remove the side cover. (If memory serves)

Should you need guidance in removing, and reinstalling a ram memory module, hit me up in a Comment.

Have HP slimline series. Came back from a break.

Try another monitor on it to verify it is the video card that has gone bad. If it does not work with another monitor then that is the likely culprit.

Replaced power supply, monitor won't come on.

Could be that you need the disc to start up your new monitor to get it to reconize on your system - It is just like setting up a new mouse, they always come with a disc.. If you have another monitor hook it up and go to the manufactures website and download their driver. This should fix your problem

HP Pavilion 523n will not turn on

have you added any hardware recently or opened the case for any reason?  the power supply is often the first thing to go on computers.  if it is still under warranty, you might need to send it off.
if you want to try it yourself, i'd say open your case and make sure the power cable to the motherboard is connected securely (there should be a 20 pin connector and possibly a separate 4 pin connector).  of course, make sure the power chord is connected securly to the back of the computer.  make sure the psu is on 115 instead of 220 (unless you need 220).
good luck!

HP LCD monitor power button repeatedly blinking blue.

Alright let me be the first, let's check the simple things first. Did you try toggling the FN+F5 or FN+F6....if it is playing on the other monitor you already did that or it was toggled for dual monitor and that's why you're not getting any video.

My computer shut off and won't come back on

Most likely your CPU is overheating. Download speedfan from this link. Speedfan monitors the temperature of your CPU. Note the temperature when the PC shuts off on its own. Let me know if this is helpful.
