bbbrad Posted December 17, 2011 Posted December 17, 2011 It been a while since I've visit after learning to build here at occ. Today as I was on loading screen playing SC2 my computer crapped out and monitor went blank. So I went to force shutdown and wouldn't work. So I flipped the power switch. I went to power back on and video card was going crazy spinning at 100% and still no signal to monitor. Also I notice 3 red lights on the back of the video card. It seemed like everything else was normal. All fans were working I could hear hdd and DVD making noise. Psu was spinning and obviously delivering some type of power... All of this happened out of the blue after about 2 years with me changing nothing. Any help with fixing this would be great. I tried taking everything apart and cleaning dusting etc. And put it back together but still same problem. System is in sig Share this post Link to post Share on other sites More sharing options...
Speedway Posted December 17, 2011 Posted December 17, 2011 Does your motherboard have onboard video? If it does then remove the card and try that to see if you get a signal. If you do then the problem is most likely the GPU. No system in your sig though Share this post Link to post Share on other sites More sharing options...
Waco Posted December 17, 2011 Posted December 17, 2011 Did you ever clean out your gpu or CPU fans? This sounds heat related... Share this post Link to post Share on other sites More sharing options...
SpikeSoprano Posted December 17, 2011 Posted December 17, 2011 I had same problem when my 8800 gts died, Fan went to 100 % at start up but could not get video, as said nothing showing for your specs so not sure if this is same problem.

Locutus Posted December 17, 2011 Posted December 17, 2011 I had same problem when my 8800 gts died, Fan went to 100 % at start up but could not get video, as said nothing showing for your specs so not sure if this is same problem. I had a similar problem with an 8800 GS a while back. I wonder if OP could try to bake the GPU. Share this post Link to post Share on other sites More sharing options...

bbbrad Posted December 17, 2011 Posted December 17, 2011 I cleaned all the dust out of the system and did the best I could with the CPU without taking the cover off. I also reseated the CPU with new thermal compound. I'm not sure what baking a GPU means. I've also tried booting with an ancient video card from an old dell and still didn't get monitor signal(nvidia gforce 6series) As well as unplugging the drives and tried booting but no change.

Speedway Posted December 17, 2011 Posted December 17, 2011 try the other PCIe slot on your mobo, to make sure that the 1st slot isn't the problem Share this post Link to post Share on other sites More sharing options...
SpikeSoprano Posted December 17, 2011 Posted December 17, 2011 If you tried with a known good video card it seems that is not your problem, do you even get a screen to show you are booting into bios ?? Share this post Link to post Share on other sites More sharing options...
bbbrad Posted December 17, 2011 Posted December 17, 2011 I just tries the other pci slot same problem. I get no screen. Just says no signal on my monitor. Share this post Link to post Share on other sites More sharing options...
SpikeSoprano Posted December 17, 2011 Posted December 17, 2011 Go back to pc fix 101, unplug from back of pc, pull out your cmos battery to reset bios, leave out for 2 min. to be safe, put battery back in, replug system and see what happens, then pull out memory cards and reseat them, see what happens, leave origional video card in while doing this, if you have onboard video take out card before you start this. May take a bit but you are breaking down what problem could be. Share this post Link to post Share on other sites More sharing options...
Speedway Posted December 17, 2011 Posted December 17, 2011 have you tried clearing the bios on the mobo? Should be a 3pin with a jumper somewhere on the board edit: or like Spike sd the battery works too Share this post Link to post Share on other sites More sharing options...
