I've been having issues with my video card...BSOD, etc. I decided to take out my card and clean the dust with compressed air. I put the card back in properly and put in all the screws and now I have no signal going to the monitor from either VGA or HDMI. I'd appreciate any help. My computer is a Gateway LX6810-01 with Windows 7 64 bit.

ok, 

 

the video card display out signal was working before,  blue screening, but functional. you took it out, cleaned it, re-installed and now it isn't sending signal to your monitor with either port..

 

now is a good time to do clean slate re-install which just might solve your blue screening problem. before you can do that, are you familiar with booting into BIOS and safe mode? have you done it before with this particular PC or any other one? if you decide to clean re-install, you will be doing both quite a bit

 

i looked up the PC bundle (nice PC by the way) , it says your display adapter is a gt 120 and you don't have a motherboard display adapter, meaning it is the video card or nothing else to use for display.

 

now would be a good time to upgrade with a gtx 750 or hd 7750 display adapter for around $100 if you want to really notice your  PC improve, your other hardware would be harmonious with one of  those.

 

if not that is ok, we can go with what you already have.

It won't display anything at all on the screen, no BIOS or anything. My monitor just says No Signal it's getting nothing from the card. I don't know what to do, I just took it out and put it back in to make sure I put it in right and it's still doing it.

ok, we have info, sad info, but still enough to go on..

 

shut down the PC, then...

 

power on, tapping the f8 key immediately and continuosly

 

any display then?

if so, choose "safe mode"

The Gateway logo won't even show, my monitor immediately says no signal every time I turn the computer on. Nothing appears on the screen at all. I'm getting really stressed :(

i really do not enjoy the prognosis of a failed component and all options need to be exhausted before that declaration...

 

is there another spare video card you can use for test? a really cheap one preferrably

 

i keep an old 9500 gt just for such purposes, just to be able to get video on a win7 machine that has no onboard video

No sadly I do not have another video card around to try that. It was working fine before I took out all the dust with the air. I made sure to ground myself before I did and everything. It's getting power and the fan is running.

if you can't get display in BIOS or safe mode, the card may be a goner, you have to start tapping the f2 or f8 key immediately on power up..

 

is your PC beeping or anything when it is powering up?

 

an easy fix may be a BIOS reset. it is easy to do and relatively harmless...ever did it before?

It does the one beep during power up that it's always done so that's normal. Not any other beeps happen. I've tried F8 and nothing ever pops up, just says on the blank no signal screen. No I haven't tried a BIOS reset, it's harmless?

yes, i had a topic similar to this about a year ago, and that solved the issue

 

a single beep is a good sign, by the way

Okay I suppose I can try that but wouldn't I have to see the BIOS on screen? How will we do that if nothing displays on my monitor?

there are different techniques for different PCs, i am looking it up now.

 

no, you don't have to have the system and OS up to do it

ok, got it..you ready?

 

http://www.wikihow.com/Reset-Your-BIOS..

 

 

it looks like the last procedure would be the simplest one

 

power down, unplug power source, open up the cabinet, locate the CMOS battery

 

remove CMOS battery,

 

press and hold power on button for a notable lapse of time  (30 seconds) to release any existing charge, reinsert CMOS battery,

 

power on and .....
