Any thoughts on my new computer problems
I have a desktop computer giving problems, following info.
The last board failed CPU and connections to the CPU by corrosion – I am near the sea.
I bought a new motherboard, new CPU, new 8 GB x 2 memory, new case, and new power supply. Old hard drive, old DVD drive. Genuine programs Windows 10 64 bit is up-to-date, MS Office and others. New WI-Fi keyboard and mouse. No video card fitted I am using on-board video. Motherboard and CPU have a one year guarantee as of 26 November 22.
Gigabyte Technology Co. Ltd. H61M-DS2 3.0 (Intel Core i3-2120 CPU @ 3.30GHz)
Problem. Computer will not allow ReadyBoost; the computer shuts itself down unexpectedly after three hours use and more often twice a day crashes with black and white squared raster over the monitor, sometimes with load noise sometimes quiet. It may shut down after a few minutes and has had red and white raster on the monitor.
New keyboard has three letters that now will not do upper case; all other keys will do upper case.
Intermittent vertical yellow line on monitor screen that is on for some uses of the computer other times not.
Checks.
All programs up to date, all drivers up to date. Windows memory test shows OK. Reliability Monitor shows shutdown as unexpected but no reasons. Going back weeks on the Reliability Monitor several programs affecting the shutdown so these were removed from the start-up sequence. The CD from a previous version of the board does not give a video driver for the newer version of the board. Cannot do a Western Digital test of the hard drive as the computer crashes in the long time needed to do a full scan. Quick tests claim the drive is good.
Choices
I reckon I have tried everything. What’s the best option just change the motherboard or dig deeper into the software as the source of the problem?
