GPU all of a suddont stopped sending image to moniter, please enter

gidday,

about 2 months ago i baged into my computer with my chair that has wheels and my screen turned off i tried restarting and nothing happend so i pulled everything out and re assebeled my pc and when i turned my power back on it was fixed , the same thing happened to me now ive tried everything but no luck gpu is a 8800gt less then a year old and montire is a 3 month old lg 22" lcd works fine if i boot it up i can hear it logging into windows but haqve no image on the monitor.
anyone have an idea the cause of this or the solution??

thanks in advanced
cheers

 

1st thing would be to beg or borrow a 2nd monitor and connect it to your pc and power both up to rule whether or not your monitor just died.
2nd thing to try would be to disconnect/clean/reconnect monitor cable and power up pc to see if get display
3rd would be to borrow a replacement power cable and test
4th, If still get no display on replacement monitor then power down your pc, remove your grfx card, clean it's connectors, remount it (making sure seats well and all power connectors are properly hooked up). Power up pc and see if get display.
5th, If your MOBO has onboard grfx, enable them (sometimes can do by jumpers on MOBO (check your MOBO's manual) (as you probably can't see BIOS either?)
After that gets beyond my ken if can't see anything on a monitor (like bios, ...)

thanks for the reply,

1. i tried another monitor and the same thing happens
2. cleaned all connections and reconnected like 10 times and nothing
3. changed power supplys and same thing
4. i totaly removed all power cables pci cards hard drives and reconnected everything and nothing
5. dosnlt look like there is an onboard gfx card

its so wierd i have my speakers on and can hear it logging in and out of windows but no picture i dont understand how a little bump into the pc can cause this. i dont think the grfx card burnt out its not possible.

if anyone else has any ideas i would be greatfull, dont want to have to take the computer to a shop.
