Kexian's right.

It's OK. Click Start >> Run >> C: > the operating system in the C drive, if you fill in D: Delete the previous operating system in which you said.

That is: multi(0)disk(0)rdisk(0)partition(2) winnt="microsoft windows 2000 advanced server" /fastdetect

If it's an XP system, you're okay.

Click Start >> >> msconfig >

Put the default=multi(0)disk(0)rdisk(0)partition(2) winnt inside

My system is an XP, a 2000

My default boot is win2000

In"My computer"Right-click > > Advanced > Boot > Recovery Settings >> Select what you want in the default operating system, and then remove the tick from the small square next to it.

Do you know how to modify boot? That file is in the root directory of the C drive. is hidden. Go online to find out how to change this.

Now that you've reinstalled your system, why not try trying out a different software, at least that way you can tell if it's a problem with your system or 360.

If you don't install 360, the problem will no longer appear, then just change to security software.

If you don't install 360, the problem is with the system or hardware, so at least one possibility can be ruled out.

Then, try to install a different system, such as the original XP, or simply change to Win7, if the problem no longer appears, then it is sure that it is a problem with the system, otherwise, the hardware is more likely to go wrong.

Step by step, step by step, identify the problem, and then think about how to solve it.

That's why 360 has a conflict with your certificate, or you should change to an antivirus Rising software. Kaba, you go and try it all!!

The memory is indeed a little small,But it should be installed360It's no problem.,It may be that there are too many things to open when you install it.,The weather has been hot recently.,Desktops are old and dead.,Notebooks may be more problematic.,It is recommended that the software that can be greened in the future try to use the green version.。

Right-click on my computer, select Properties, select Advanced, select the settings above the performance, then select Advanced, select the change at the bottom, change the 2 values in the custom to 2048, and then click on the settings next to it, and then confirm all the way to the end. That should be fine.
