My laptop, a Gateway NV57H, starts up fine, but after 10 minutes or so it becomes incredibly slow and everything is unresponsive. I used to get a bluescreen (kernel_inpage_error) after it being in this state for a while, but I researched it, ran a memory diagnostic, and found out one of my sticks of RAM was fried. Replaced both, doubling the capacity to its limit (8GB) and I still have the problem. When task manager is open during all of this, it shows that I'm only using 1.6 GB of the 8GB of RAM available, so I don't think that's the problem. I ran chkdsk and sfc /scannow from the command prompt, both said there were no errors found on the hard drive. I've ran malwarebytes from safemode a couple of times, it found some trojans and potentially unwanted programs and such that I quarantined and deleted. that didn't seem to fix the problem, and scans now come up clean. I'm running another now, just in case. The laptop runs fine in safe mode, no lag and no errors. I researched some other threads where people had similar problems and they said it was caused by having two antivirus software trying to run at the same time. I have kaspersky, but it's outdated. I turned off windows defender because it was trying to scan, and then started back up and the problem still wasn't fixed. Does anyone have any idea what the problem might be and how to fix it? Thanks!
