Usually when a computer 'freezes up', it is due to the Processor (CPU) overheating.

I assume when the Ram Memory modules were replaced, the computer was cleaned out on the inside?

Thermal Paste:

The top of a Processor, and the bottom of the finned Heatsink that sits on it; are not perfectly smooth.

A magnified view would detail, 'Ridges, Valleys, and Pitholes'.
When the Processor and Heatsink are mated together, there are now Air Pockets formed in-between them.

Air is now an Insulator, not a Conductor.
Thermal Paste fills the above imperfections, and is an Excellent conductor of heat.

You want to transfer the heat from the Processor, to the finned Heatsink; so the fins of the Heatsink can radiate the heat away.

(Air flow from the Processor fan, helps carry heat away from the fins of the Heatsink)

After time (age), and heat; the Thermal Paste dries up.
Looses it's thermal conductivity properties.

Processor overheats, and computer freezes up.

Let's look at the Specifications for the Pavilion Elite m9515y, and then I will show you a detailed view; of the top of the Processor,

AMD Phenom X4 9850 processor,

This is a GENERAL view of a Heatsink/Fan combo.
It is the finned Aluminum Heatsink I would like you to look at.

There are smaller views shown underneath the large Main view.
Click on the small view all the way to the Right.
This shows you the Bottom view of the Heatsink.
The area that sits on the Processor.

Secondly, an AMD Phenom X4 9850 runs -> HOT.
55 degrees Celsius to 61 degrees Celsius.
That is 131 degrees to 141.8 degrees Fahrenheit, respectively.

Replacing the Thermal Paste will be a reoccurring procedure.
Especially if the computer is dirty inside, and not cleaned on a regular basis as needed.

(Some areas have a high dust content. Cleaning the inside of the computer, is based on how fast the computer get's dirty inside)

1) Computer off, all cables are removed from the outside.
If you are NOT exactly sure where they all go, NOW is the time to make notes, and a drawing.

2) I lay a soft static free cloth on the table I'm working on.
(If I'm not using the workbench)
Helps prevent scratching the table, and computer.

Then after removing the Side Panel, I lay the computer on the table, opening of computer case - UP.
Makes it easier to work on the computer.

-> STOP <-
Now FOLLOW Anti-Static Procedures.

Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static, BEFORE reaching inside your computer.

Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.

IF, you leave your computer in the middle of working on it, be SURE to Touch the metal frame again, upon your return.

4) The Processor fan has a cable, (Wires), that comes from it, and plugs into the motherboard. This cable is unplugged from the motherboard.

The Phenom X4 9850 uses an AM2+ processor socket,

Looking at the Yellow retaining bracket, note the two TABS on either side. In the photo, the Left side, and Right side.
The Heatsink will have Clips, that clip to these Tabs.

Here is more detailed information,

Scroll down. Go to the bold subheading -
Step 4: Removing and installing the processor

Scroll down a little more, click on the + sign to the left of -
Remove and install a socket type processor

In the four views shown, look at the Top/Left view, and the Bottom/Right view.

Unfortunately there are many styles of these retaining clips.
Most have a lever on the side, that you pull up on, and this releases the U-shaped clip; from the processor socket's retaining tab.

Some have it where there is a flattened area for the top of the clip, that is pushed down on, and this brings the U-shaped clip down away, from the processor socket retaining tab.

Once BOTH clips are released, then the Fan/Heatsink combo can be lifted off of the Processor.

5) I use an old credit card to scrape off as much of the old Thermal Paste, as I can.
(It's PLASTIC, and stiff)

Scrape off the top of the Processor, and bottom of the Heatsink.
(After you scrape once, then use a cloth to wipe the credit card off, and proceed again)

After removing as much as I can with the plastic scraper, then I use Q-tips dipped in Isopropyl Alcohol. (Rubbing alcohol)
I find 91 percent and higher is best. 70 percent can be used.
IMHO 50 percent = NO

It is now 50 percent WATER, and 50 percent Alcohol.

Takes a LOT of alcohol soaked Q-tips! It usually turns into a gooey mess.

Isopropyl alcohol is EXTREMELY FLAMMABLE!
Use in a WELL ventilated area with NO sparks or flames present!

How clean? Clean enough to eat off of, bvi47.
(But don't! Ewwww! lol!)

Then PROPERLY apply fresh, new Thermal Paste,

Reinstall the Heatsink/Fan combo. Reconnect the Processor fan cable to motherboard.

While you are at it, remove the Ram Memory one more time, and reinstall.
Because Ram Memory gets bumped very easily, and the ONLY method to ENSURE that it is seated well, and properly; is to remove/reinstall.

You should check your monitors connection to the pc. If the connection is good, you will need to do one of two things:

1. Try using a monitor that you know works. If that monitor works on your pc then your other monitor needs replacing.

2. If you connect another good monitor to the pc and it does not work, you will need to replace your video card in your pc.

Good Luck

That more than likely means the video (graphics) card inside the computer is bad. The monitor seems to be ok if it is displaying No Input Signal. Isolate the problem by connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it t the computer. If the Borrowed Monitor displays the No Input Signal then your video card inside the computer is bad. If the Borrowed Monitor works and displays your desktop icons, then your original monitor is bad and the video card is ok.

No signal detected message on monitor, cpu and monitor are on

Good Day Jboone563!

You need to check if the VGA cable is properly fix to the monitor and video card. Loosen connection or no contacts is the reason for the "no signal" display on your monitor.

This means that there is no signal coming out from the video card, going in to your monitor. If by fixing the VGA connection did not fix it, try removing the video card from the motherboard and then reseat it properly to the motherboard slot.

If this do not resolve the problem, Jboone563, I'm sorry but you will need to replace the video card.

I have the VE278Q which is connected by display port, every time i turn off my computer and then turn it back on the monitor can't be found, I have to unplug the display port cable, unplug the monitor,...

when you say monitor can't be found did you mean the monitor has no reactions when you turn on your pc?

here are some test you may need to do to know which part is faulty
1. Turn on your computer, did it display the monitor's logo on screen? When it does monitor is good, when only blank screen it could be the vga cable or the video card.
2. See if the led indication lit. When it lit to steady green, it's good signal is coming in from the video card. It should be followed by screen display. If no display it could be the backlight inverter lamp busted or faulty inverter board. When lit green then turns red, no signal coming from the video card. Check vga cable if fix properly to both monitor and video card. Or may need to reseat properly connection of video card from the motherboard. If no led indication lamp, then monitor is dead. Check ac power cord for continuity using multitester. Check power supply section in the monitor, replaced bulged or blown capacitor with exact value, this components were the first to get affected when lcd monitor failed o turn on.
3. When computer was turned on got display and then monitor turns black, go check the vga cable, Fix the connection properly or may need to replace it with new one.
4. When no signal appears or display blank screen after logo, then check video card. First remedy is to disconnect it the reseat properly to the motherboard. If this have no effect change your video card.

go follow these steps and let me know which is closely to your problem so I can give you a good advise.

Monitor starts then goes off, no signal

I would check the LCD against another monitor. It does not have to be a LCD, a regular monitor will do.
This will tell you 2 things, 1. The Video card is good or bad, 2. The Cable is sendinf a good signal.
If when you startup the monitor, you see a display and then after a few seconds it display's a no signal message, this is consistant with a Bad cable or cable ends. or Bad VGA card from computer.
Hope this helps. Good luck..
P.S. If you have move the PC, you may want to open the unit, and re-seat the Card. If the card is not making a solid connect on the board, it will display these syptoms.

If not resolve let me know whether any beep/sound is coming out of your CPU box?

No display on monitor

Hi, sounds like a problem with your base unit, might be a lose graphics card, a stick of memory might need taken out and put back in. shouldnt be expensive to fix. as that will give you the fault that you describe with the monitor. as the base unit aint posting, and the signal aint being recieved, if you have basic knowledge you should try taking out the graphics card and refitting it, usually does the job :-) All the best, John
