Sometimes my monitor won't start with the PC (no signal)

[NeRObutBlanco]

Hello everyone!
Here's the problem;I always have my monitor on standby so when I start the PC the monitor follows by itself.Lately,sometimes (let's say 1 out of 5 times) my monitor won't start with the PC and when I turn it off and then on again it says "no signal" and returns to standby.I hear the beeps and boot sounds/music like always so the PC definately boots normally.What I do afterwards is I just turn thePC off via keyboard button,wait a while and then turn it back on and voila! no problems.
So,what could be doing this? Could it be the video/graphics card,or the monitor,or perhaps even a problem with Windows or the system.

My PC specs (yes,I know it's not exactly up to date):
MB: GIGABYTE H61M-DS2 rev 2.2
CPU: Intel Pentium G860 3.00 GB Dual Core
RAM: 4GB Kingston something DDR3
GPU: Nvidia GeForce GT 630 1GB
Monitor: Well.....a pretty old EIZO plasma...
OS: Vista Home version
By the way about voltage I really don't remember the model but I'm pretty sure it's 500W.Should probably check it though.

Thank you in advance.

The issue is almost certainly not with the monitor but with the PC, power supply, motherboard, maybe video card issues. Could be RAM.

Swap the monitor and test with a different one for a while see what happens.

See,the issue is that there is no other monitor available.Also,I'll need to try it many times before I actually deduct what the problem is since it happens at random and not that often.

Without testing with known good parts you won't be able to find out where the issue is. So either try a different monitor, try your monitor with another system, try a different video card, try a different power supply, try yours in another system, etc...

Think we can somehow test if the video card is dying? Like with a benchmark or something?

Yes, running a benchmark program can often show if the card is good or not, 3DMark is a good one to use. It's not a totally reliable test though, as the issue may not be with how the video chip runs but maybe the PCIe interface which may only cause issues at times during boot-up.

Sounds like it's worth a try.The PCI interface? Can you tell me more on that? I'm not exactly an expert.

PCIe, that's the connection the video card is in.
