As soon as I got home, expecting to relax and enjoy my Friday while playing games on the PC, I unexpectedly encountered an unpleasant problem: As you can see in the video, I get some rainbow show at start, then the computer goes on to load normally and well, so far it works normal with the unpleasant stripes laying there though, I'll try recording another video while the PC is being used for more details. Ignore the video's tittle by the way, I recorded and uploaded that with the phone, before checking anything, I've already discarded the other two options. I've also removed the Graphics Card and cleaned it inside, it did have some dust but the problem remains... I'm also unsure if it could be the DVI to VGA adapter: Warning: Spoilers inside! Currently I don't own another one, so I can't be sure if the problem could be coming from the adapter itself (it's 5 years old now). Well, what do you think the problem is? Driver? Broken? Damaged? Meh... I just didn't want to spend money on new parts for now, but I'll have to buy a new motherboard and graphics card if this is indeed broken. Thanks in advance. EDIT: Here's the follow up video which starts from where the previous left off: I hadn't tried it yet when I started recording, apparently the monitor has problems detecting the proper display settings and vice-versa... Due to not detecting anything, the monitor ends up suspending itself after a while.
