Suddenly the power went out, the computer turned on, and there was no response at all
If the computer does not respond after a sudden power failure, you can check it by following the steps below: 1. Check the power connection: - Make sure that the power cord is connected to the power socket. You can use other equipment to check if the socket is charged. For desktop computers, check the power switch on the back of the host to ensure that it is in the "on" state. - Check whether the power cord is damaged or disconnected. Check whether the two ends of the power cord are firmly connected, loose or broken. 2. Checking the hardware connection: - Under the premise of cutting off the power supply, open the side cover of the mainframe box and remove the memory stick, replacing the position of the memory installation slot. - Find the battery of the main board, remove it, and discharge it for 15 to 20 seconds. You can also use the jumper-cap next to the battery to restore the default settings of the main board. 3. Checking with external equipment: - With the help of the USB flash drive PE system, restart the computer and use shortcuts such as ecs, F10, F11, or F12 to select the USB flash drive to start. Eliminate the reasons for sudden power failure, inability to identify the computer's main hard disk, or system errors that cause the system interface to not be able to enter normally. 4. System Recovery: - Many computers had a system backup and could choose to restore the factory system. Or he could connect to another computer and reinstall the system. If the above methods still do not solve the problem, it may be caused by a hardware failure. It is recommended to contact a professional technician for repair or replacement of related components.

Suddenly fainted, no response, breathing
A sudden fainting, no reaction, but breathing could be caused by a variety of reasons. 1. ** Reflex syncope **: - Vasovagal syncope was more common and could be triggered by emotional stress (such as pain, seeing blood) or body position change. Consecutive syncope was related to specific actions, such as coughing, urinating or defecating, after meals, after exercise, etc. Carotic syncope was often induced by non-mechanical stimulation factors, such as tight collar, shaving, etc. 2. ** Cardiogenic syncope **: - There were two types of syncope: Arrhythmic syncope and organic cardiovascular syncope. Arrhythmias were the most common cause of cardiac syncope. For example, it could be caused by conditions such as acute myocardiac arrest, heart valve disease, and cardiovascular disease. 3. ** Brain Syncope **: - Syncope occurs due to brain tissue starvation. Brain diseases mainly include severe cerebral stiffness, cervical vertebra disease, and temporary cerebral ischamic attack. 4. ** Low blood sugar attack **: - When the brain lacks sufficient supply of glucose, resulting in imbalance, there may be a sudden fainting episode. At this time, if the blood sugar is <2.8mmolL, the symptoms can be completely relieved after rapid replenishment of glucose. 5. ** Orthostatic Hypotension **: - It refers to syncope caused by excessive blood pressure drop in the upright position, including drug-induced, primary or secondary spontaneous nervous failure, and hypovolemia-induced orthostatic hemorrhage. 6. ** Temporary cerebral ischaemic attack **: - If the reticular structure of the brainstem was involved in a momentary cerebral ischaenia attack of the vertebrae and the basement system, fainting episodes could occur. 7. ** Adenosine-sensitive syncope **: - After detailed clinical and various examinations, the common cause of syncope was negative, but the syncope had a positive reaction to the adenosine-bound or ATP-bound test. The disease was mainly manifested as a sudden loss of consciousness. Generally, there was no obvious cause. Some patients even had an attack when they were quiet or lying down. Once such a situation occurred, the patient should be placed in a supine position immediately, with the head lowered and the feet raised, and the belt loosened to keep warm. Witnesses could also start from the lower limbs to perform a centric massage to promote blood flow to the brain. At the same time, they could press the patient's Hegu acupoint or Renzhong acupoint to wake the patient up through pain stimulation. Do not get up in a hurry after fainting patients wake up to avoid fainting again. If it is considered that the patient has an organic disease, after on-site treatment (such as supplying sugar to patients with low blood sugar, etc.), they should go to the hospital in time to treat the cause of fainting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
