Computer won't boot?

Question

My computer was having issues such as being slow, bluescreens, extremely slow startups, and freezing. So my first option to fix it was the trial and error decision. What I did was I took my computer apart (GFX card, RAM, Fans, PSU) and I cleaned all of the dust and **** off of the fans. Then I put it back together and it turned on perfectly fine and such, but my monitor would stay black. There's a little light that turns blue when it has signal from the hard drive, and an orange light when there is no signal. When there is no signal, it would tell me on the monitor in words. If there is, it'd turn on. But when I ran my computer it would turn the monitor on but it would stay black and give the orange light and wouldn't work, so I unplugged everything and redid it and put my graphics card in a different way and it eventually booted up after I pushed my ram all the way in (I think it was what was causing the problems) and now it boots up fine, but it says my cmos time and date was missing or wrong or something and now when it boots up it goes to the "Windows is starting" screen and restarts. What could be the problem?

Answer 1

DO you still have the windows disc and the drivers? If yes try to install( and by install i mean format to zero your hdd, or buy a new hdd) the OS and the drivers one by one. Most likely you got a virus. An try to replace the CMOS battery too.are all the connetions inside the pc put together correctly? And also if your BiOS has the option, select the "test on startup". It tests almost everything before it reads the hdd( mostly hardware). If still not it might be, but that's the least possible, the nor/nand chip(bios) is corrupt( a virus or wrong settings), and in that case you shall replace the motherboard. Please keep me updated.

Answer 2

It look like the CMOS settings got erased and now Windows is trying to start up with the wrong hard disk settings. The new SATA hard disks can be configured in two modes, native, and enhanced or something like that. Simply choosing the mode the hard disk was installed to use sometimes can fix this problem.



You need to get into BIOS set up to do this. On most machines this means pressing DEL or F1 key when the computer is booting. Look for the setting SATA or ATA hard disk mode, or something like that and change it around, the reboot.

Answer 3

problem 1 - the RAM was not seated correctly - sounds like you fixed that one

Problem 2 - Replace the CMOS battery located on the system board - by sure you install it the correct way (pay attention to the polarity)

Problem 3 - Sounds like one of your windows start-up drivers is not loading correctly, try starting the computer in safe mode by pressing F8 before it says "Windows is starting", then uninstall any new software that you installed.
