I have a laptop that had a motherboard replaced and ever since my computer freezes every now and then. It so random that it makes it difficult to pinpoint the issue. Sometimes it freezes up at login screen and sometimes we can work on it for hours and nothing would happen. First we thought it was a driver issue so we updated all the drivers from Dell website. Then we thought it could be one of the services so we did a clean boot but that didn't fix it. Then we did hardware diagnostics, chkdsk, sfc scannow to make sure it was nothing related to Hardware or Software. Finally we thought it was Windows updates so I uninstalled most of the updates after fresh install but that doesn't seem to have fix it either.
Checked event viewer and there's nothing suspicious that points to this issue
It's a Dell Latitude 3450 with 64-bit Windows 7 on it.
Can anyone help??
