Crashing and shutdown problems can be symptomatic of a variety of things to include hardware/software issues, overheating caused by a failed processor fan, bad memory (RAM), failing or underpowered power supply, CPU overheating, motherboard, video card, faulty or unsigned device drivers, CMOS battery going bad, BIOS and firmware problems, dirty hardware components, programs hanging or unresponsive in the background, and even malware.
Some rootkits can also trigger BSODs, shutdowns and various stop error/shutdown messages so it would also be wise to perform a scan for this type of malware. Download and scan with Sophos Anti-rootkit
, Panda AntiRootkit
or AVG Anti-Rootkit
Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
Note: Not all hidden components detected by ARKs are malicious. It is normal for a Firewall, some Anti-virus and Anti-malware software (ProcessGuard, Prevx1, AVG AS), sandboxes, virtual machines and Host based Intrusion Prevention Systems (HIPS) to hook into the OS kernal/SSDT in order to protect your system. You should not be alarmed if you see any hidden entries created by these software programs after performing a scan.
- Disconnect from the Internet or physically unplug you Internet cable connection.
- Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
- Temporarily disable your anti-virus and real-time anti-spyware protection.
- After starting the scan, do not use the computer until the scan has completed.
- When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.
