I have been using my PC for around 6 years now, with no real issues, however a couple of months ago my computer began to randomly crash, with red lines appearing on the screen and the screen would sometimes turn black/grey/green as well, and I would have to turn it off.

After it started happening I tried many fixes, including removing all suspected viruses, uninstalling windows updates and installing newer ones (which I thought may have been the problem as it started to happen after an update, but it doesn't seem to be), and others which I unfortunately can't remember, however I have not attempted to fix anything within the actual computer as I hoped to avoid that, which it looks like I won't be able to.

Patterns with the problem: If I leave the computer alone for a long amount of time and then go back on it, there will be no red lines on start up, and it will take much longer to crash (5-6 hours), however if I go on it shortly after it crashing (<2 hours), there will be red lines on start up and it will crash in a much shorter time.

It'd be massively appreciated if you could give any fixes you may have :)

Sounds like a GPU or power supply issue. try taking out the video card and use the onboard. If it works correctly with onboard then put the video card back in and make sure you have the latest video drivers. It could be due to overheating either the video card or power supply. Here is a good quality 550w at a great price if want to test parts.
