Lately, I've been having issues with my PC. I'll be working on it and the screen will go black.

The PC tower continues to remain on, but my monitor says, "No Signal Found".

I'm confused by this. Does anyone know if this is a hardware issue or software issue? More importantly, if it is hardware, do you think it's the monitor, analog cable, or video card?

I thought it was dust initially, as it had a lot inside the PC tower, but I blew all the dust out. Things were fine for a while after that, and I thought I fixed the problem. Then it happened again.

I can tell you that if I reset my PC tower and wait a couple minutes before starting it, the signal goes through and I get picture back on the monitor.

So experts, what do you think is wrong with my PC?

i wouldn't say i'm a expert but it sounds like your videop card is goin out

[Burn]

Yeah. I'm leaning towards video card as well.

You're not bumping the cable when this happens?

Nope. I'll be playing a game or surfing the net and the screen will just go black. It's quite annoying. My PC is only a year or two old too.

From personal experience, video cards tend to be the most fragile parts of a PC.

Though mine never bothered to wink out like that, they just died when the computer was turned off and with a fault video card it wouldn't boot up until I took the busted buggers out each time.

I'd make sure that the monitor cable is fully seated and that it's not torqued in such a way that could damage any of the wires. Then I'd check to make sure that the Video card is fully seated in its slot. Next I'd look at the heat situation in your case; it is well ventilated or is it in a place such as a cubby where there's no where for the vented heat to go? Try taking the side off of the tower and see if that stops the problem. If it's still continuing Id suggest finding a new video card.

My tower sits on top of my desk, right next to my monitor. There is nothing behind it and a good foot and a half between it and the wall behind.

I did remove the cover and blow the accumulated dust off earlier. As for the cable, I've disconnected/reconnected it so many times trying to figure out the problem that I'm 100% sure it's connected correctly.

Seems like the majority so far are suggesting it's the video card. I can tell you that the one I have is stock, an nVIDIA GeForce 6100. What would the average price be to replace it with something of the same or better quality?

Umm... There is no 6100 graphics card. There is however a 6100 Nvidia GeForce Chipset which features onboard video. Are you plugging the monitor into an actual expansion slot graphics card or into your motherboard itself?

I need to know what slots you have for expansion. Everyone and their mother has PCI slots. Your computer should also either have an AGP slot or a PCIe slot as well.

For a minute I thought we were going to have a discussion about saying something really divisive in front of a crowd.

Okay, thanks for clearing that up. As for your other questions, I'm not sure. There is only one connecting spot for the PC to Monitor cable to hook up to (it's just below 4 USB ports and just above my modem port). The front of my PC says, "PCI Express slot available" though.
