Hi,
I am troubleshooting a system of a friend. It is an low-end-system with an AMD A8-6600 APU, 4GB of RAM, an AsRock motherboard and a kingston ssd.
From time to time when you try to boot it the monitor doesnt receive a video signal (dvi). This is resolved after a forced reboot most of the time. The video signal is also occasionally lost while using the computer at no particular time.
CPU and GPU stress tests both resulted in BSODs, CPU was IRQL_NOT_LESS_OR_EQUAL and GPU BUGCODE_USB_DRIVER. I also randomly got an PAGE_FAULT_IN_NONPAGED AREA win32k.sys and a BSOD regarding atikmdag.sys.
I ran chkdsk /f, sfc /scannow, cleared the registry of useless entries, updated all drivers, removed weird or unneccessary software and checked for malware. Temperatures also seem to be fine and there is plenty of thermal paste left.
I am thankful for any ideas regarding my problem :-)
