So I've been having a massive problem with my computer: My games keep crashing. Whether it's after 2 minutes or 2 hours, most of them eventually crash. I've noticed that the "High-requirement" games such as Overwatch and The Witcher 3 are the ones that crash the most. Now I've tried a whole bunch of things: Increase fan speed, increased core voltage, cleaned out my computer of dust, uninstalled then reinstalled my graphics driver, removed my old anti-virus program, disabled "NVIDIA Streaming Service" service, even gave a good look at gpu and cpu temperatures during gameplay and none of these things seem to work.
I don't have any money to afford a new gpu if it's faulty, so I really hope to find any other solutions before I have to replace it with the money I don't have. At first I thought it was because of the room temperature, since it's been very warm in the summer, yet when I play games such as Overwatch on Medium-High quality, the temperature of my gpu and cpu are usually 50-65 degrees celsius, which I've heard is normal. I've done clean installations of my graphics/display drivers so I honestly don't think that's the issue. I heard that just installing the driver from the installation CD and stopping any future updates on the driver might work, but I highly doubt it. Here are my specifications:
MSI Twin Frozr NVIDIA GeForce GTX 660
Intel Core i5-4570 CPU @3.20GHz (4GPUs) (Also have Intel® HD Graphics 4600, but I think that's included with the processor, unsure)
2TB Hard Drive
HP 22" Monitor
System Model: H81M-S2PV
I'm on my last legs, I have absolutely no idea what to do. Unfortunately, I really have no idea what to doI'll bookmark this post and check every day for replies and respond ASAP with anymore information you need or any advice you have. Thank you.
