Solved monitor stays black, tried new cables and even new monitor

March 24, 2012 at 08:38:26
Specs: Windows Vista
When I start my pc, everything sounds like it's working fine. All fans run, no strange noises. But nothing ever comes up on my monitor.
I bought new DVI and VGA cables, doesn't work....I bought a new monitor and this is what it does now:
It stays black with a sign in the upper left corner that flashes between Analog and Digital. It does that for a few seconds, then it goes completely black and the power button flashes, like it's in sleep mode.
I am very computer stupid...what can i do to fix this? My computer is an HP and the old monitor was also HP, the new monitor is Samsung.

Ur nvidia chipset has failed due to overheating. Very well known issue with ur computer. It is possible to fix ur mainboard by reflowing the northbridge but u may be better off replacing the computer.

It's not the cables & it's not the monitor. It's a shame you didn't post here 1st because we could have saved you from needelessly buying those items. The problem is that the tower isn't sending a video signal to the monitor. That could mean the video card is bad, the motherboard is bad, the CPU is bad, or the power supply is bad. You need to troubleshoot to pinpoint the problem. When you 1st power on the system, there should be a single beep, that is an indication that everything is working properly. If there is no beep or a series of beeps, that means there's a problem. Are you hearing any beeps at startup?

Here it is at HP:

A single beep generally means everything is OK. Do you or have you ever opened the case & cleared out the dust?

good thats the info we needed, this low single beep is a post beep indicating everything should be working properly, u seem to have an integrated video chipset,
so power would not be an issue can u try vga to vga cables not dvi to vga?
do u know someone who can give u an unused graphics card so u can test if u recieve video from a gfx card?
as far as iam concerned this seems to be a problem with the onboard video chipset

It just dawned on me to hook up my monitor to my laptop and it works perfect! Geez, I hope i didn't lose everything on my desktop, all that data that i need for work! i haven't tried to take off the case yet, i will try that though...and the only person i know that can help me with a graphics card is the Staples Store that sold me the computer and they are two hours away from me....

Thank you both so much for helping me! Is there anything else you think i can do on my own to fix this? If not, i will wait til i go to the city and bring my tower to them to fix it. It can be fixed without losing all my data right??

"I hope i didn't lose everything on my desktop, all that data that i need for work! " "It can be fixed without losing all my data right??"

probably yes, barring any damage to the hard drive. If this is your top priority, you should get the data first, then try and repair it and you should make this known if you take it to someone. If you could remove the hard drive, your laptop could be used to retrieve the data.

What are the chances that you can borrow a video card from someone? It could be either a standard PCI card or a PCI-express card. If not, maybe Best Buy or a PC repair shop would let you "borrow" a card for testing purposes? Or you could buy a card & return it if it doesn't fix the problem? Let us know if you need a recommendation for a video card.

depending on ur power supply but since this is an OEM machine so i thing the psu would be low powered so u should go for a low powered graphics card such as gt 240 or HD 5670 or even HD 4670, something in this range
