No Video signal, extremely frustrated

post #1 of 12
Thread Starter 
I was performing some routine maintinence on my pc, cleaning and whatnot. Starting it back up again, I suddenly cannot get a video signal whatsoever. I'm fairly sure the CPU is working, but then again, maybe not (the fan does go on).

So, I'm down to whether it is the mobo, cpu, or most likely, the video card. The video card was the only component I did NOT clean/do anything with because I felt it looked okay. So, now I'm starting to believe it's the mobo.

Anyway, the only two things that happened that I think could have possibly done anything were
1. When reseating the ram, I pushed EXTREMELY hard, and could have POSSIBLY cracked the mobo. However, I don't even think the thing would turn on if this happened.
2. when using compressed air on the mobo, I accidently sprayed sideways, causing the all too-familiar icy tetraflurothane i'm sure you've all been hit with at work/school to come out and spray on a part of the mobo near the pci-e slot. I'm not sure if the mobo would be in trouble from that, but there didn't appear to be any condensation, and it evaporated fairly quickly.

Any idea on whether this is a problem with static electricity, that my strength exceeds my intelligence, or a bad video card?

Thanks OCN.

Did you ground yourself before you went to town in your computer? Did you actually physically touch anything other than the ram? I would say the first thing I would do is take the mobo out and see if you cracked it, if you broke it then you know what the issue is.

PS. Your supposed to wait 24 hours to bump, not 24 minutes.

first... reseat the video card..

second.. take out ram and try to boot with only one..

third.. reset CMOS...

that dont work.. then turn the power supply off.. with the botton on the back.. and discharge all caps by pushing the power button..
this will take time.. but usually it works unless something is really broke..
wait 5 minites between pushing the power button.. and do it over like.. half an hour..

for the record... a PC can be completly submerged in water if its off.. and dryed before its turned back on..
and no.. the icy blast of compressed air liquid will not hurt it.. but breaking the board might when u pushed hard to seat the ram.. and unless u heard cracking.. i doubt the board is broke... but u could of broke some traces inside the board when it flexed..

Obviously I grounded myself and have a wrist strap, that's a pretty basic thing.

As I was cleaning, I did touch other components besides the ram, but those were the CPU fan and two case fans. I used compressed air on the rest (except for the ram, had to move it to get the air can into position properly.

As I took out the mobo, I saw no cracks whatsoever. As I said above, if it was cracked, I doubt it would post/boot (as it appeared it was doing, due to the time between when i turned it on and the caplock/numlock buttons flashing + when I put speakers in, I DO hear the vista startup sound.

what is said above ^^

seriously make sure that the graphics card is connected fully(you shouldnt have to apply excessive amounts of force though...) and that your monitor is actually connected completely. If your motherboard has onboard video, make sure its deactivated ...

Update: Thanks guys, so far, i've reset cmos etc, then i tried booting with one stick (I have 4 * 1 GB corsair, I mis-labled my system), then two, then three. All of those times, it seemed to work. Now I'm trying to boot with four and it just doesn't want to work. It's very strange... This stick was working before.

Bought the ram recently, should I try to RMA?

Do what is stated above and make sure your Video card is fully seated within the PCI-E/AGP Slot.

However I would like to point out that if your motherboard is sat correctly on motherboard risers it would be rather hard to crack your motherboard when inserting RAM. Thay are fairly durable.

Some people get very worked up by this but touching components is not a KILLER oh no kind of thing. Yes its best not to but if you do then life is not immediately over.

EDIT *

These things happen. It does not mean your RAM is at fault. However I would run Memtest on them.

first thing is to figure out if its the ram stick or the slot..

so put one of the known working ones into the slot that the one stick wont work in and see..

if it works.. then put the questionable one into the slot that is now open.. sometimes just sticks get a mood and seem to like one slot over another...



BTW... did u get ur video working yet?

Thanks guys.

Will run memtest on the three sticks that do let me boot.

Fourth one, no matter how many times I reseat it now, will not work. It's strange, but I have a feeling that either I may be seating it incorrectly (doubtful, but will take out mobo in the morning and try that) or the stick is dead (probably so, but not entirely sure why).

+ rep to all of you

Will update in the morning. Thanks
