Old Bird Advice! Recurring problems!

There's something wrong with the system. Just reinstall the system directly with a verified system disk, so that you can automatically and smoothly solve the problem that the win7 system cannot be logged in. These are possible with a USB flash drive or hard disk, and the installation speed is very fast.

But the key is: to have good compatibility (compatible with IDE, ACHI, RAID mode installation) and can be automatically and permanently activated, can automatically install the machine hardware driver sequence of the system disk, which can be the whole process of automatic and smooth reinstallation of the system. Here's how:

1. U disk installation: ** A verified system installation disk file (ISO file), use ultraiso software to make a boot U disk to install the system, and use this good system U disk to guide the start machine, you can install the system smoothly;

exe "Finish stupid to the non-system partition of the computer and then run" to install the system. exe", directly press enter to confirm the restore operation, and confirm the automatic installation operation again. (Pay attention to back up the important data of the C drive before execution!)

3. **version tutorial: How to give you the detailed **version installation tutorial in this regard? Can't be attached to the grandson.

will be judged by the system as a violation. The address is in the ......... in the upper right corner of the Know pagesi xin zhong………Yes! Wangkaimeng!

Restart it as he said, then use 360 Security Guard to fully detect it, and then fix it. If that doesn't work, redo the system.

Nitrogen deficiency: The leaf color is light green, the basal leaves (old leaves) turn yellow and gradually develop upward, and are brown when dry. The plants are short, have few branches (tillers), and appear premature senescence. If the fruit tree is deficient in nitrogen, it is manifested as small fruit, few fruit, and hard peel.

Phosphorus deficiency: The leaves become smaller, dark green or gray-green, lack of luster, and often red or purple in color. For example, on the stems and leaves of crops such as corn and tomatoes, purple-red stripes or spots appear obviously.

The stems are short and thin, the basal leaves turn yellow, heading, flowering and maturation are delayed, and the seeds are small and not full. Corn ears are bald and pointed. Sweet potatoes and potato chunks become smaller.

Fruit trees drop flowers and fruits.

Potassium deficiency: the stem is easy to lodging, the leaf edge is yellowed, scorched, fragmented, necrotic spots appear in the vein, the whole leaf is sometimes cup-shaped or shrunken, and there are many brown roots. Grain crops and other crops with high sugar content require more potassium in the later stage of growth, such as cereals, potatoes, watermelons, grapes, etc.

Iron deficiency: the veins lose green, showing a clear reticulation, and in severe cases, the whole leaves (especially young leaves) are pale yellow, or even whitish. Fruit trees in the north, such as apples and pears, are prone to this symptom.

Iron-sensitive crops are peanuts, corn, sorghum, potatoes, vegetables (spinach, tomatoes, etc.).

Boron deficiency: It is first manifested at the apex and stops growing. The root system is underdeveloped.

The leaves are dark green, the leaves are small and thick, and the young leaves are deformed and shrivelled. The leaf veins are irregularly greened, the flowers are not well developed, the fruit ears are not fruitful, and the roots and berries are rotten and necrotic. For example, soybean bud blight, apple fruit shrinkage disease, celery stem crack disease, radish heart rot, etc. are all due to boron deficiency.

Zinc deficiency: leaves lose green, leaves grow in small clusters, spots appear on both sides of the leaf surface, plants are shortened, internodes are shortened, and the growth period is delayed. Such as tree leaf disease, corn white seedlings, etc.

Copper deficiency: new leaves lose green on the tips of young shoots, white curls between the leaves are twisted, necrotic spots appear on the leaves, and then wither and die. For example, cereal crops are clustered with white plants, and when they are serious, they do not head and do not bear fruit.

Copper deficiency in fruit trees is manifested by clustered leaves at the top of the leaves, and the leaves and fruits are discolored.

Manganese deficiency: In the early stage of manganese deficiency, small necrotic spots appear between the leaf veins, and dark green stripes appear on the leaf veins, which are rib-like. The loss of greenness is first manifested on the new leaves.

Molybdenum deficiency: It first appears on old leaves, and the interveins of the leaves lose their green to form yellow-green or orange-red leaf spots, the leaf margins are curled, and the leaves wither and even die. The leaves are bent upwards and wilted, the flower development is inhibited, and the seeds are not full.

The fertilizer efficiency of molybdenum fertilizer is mainly manifested in soybean and cruciferous crops, especially soybean and peanut.

Looking at your problem description, there is a flashlight scanning there to scan the system icon when reading and writing the hard disk, and you directly restarted the computer several times when the computer was running normally, so it personally feels like a problem with the hard disk.

1. It is a software problem, because an abnormal restart will cause the system files to be lost, which will make the computer slow down when in use. Workaround, reinstall the system.

2. It is a hardware problem (hard disk problem), if it will, it is recommended to scan the hard disk to see if there are any bad sectors, and if not, it will have to be replaced.

In the way of difficulty, let's reinstall the system first.

It is clear that the hard drive has been damaged.

In addition, it is better to emphasize that Jinshan Poison Bully is better to uninstall it immediately, and I don't want to talk about it.

Yours isn't win98, right?,And a flashlight?! ...

Just scan it with the driver software! This should be a NIC driver problem.

It means that there is a network but there is no connection, and the connection is good.
