Lenovo ideapad u310 - white screen at startup

SOURCE: How to uninstall Vista and load XP in Lenovo Y510 Ideapad

Several points:

1. Although you may prefer XP to Vista, it is probable that you are simply
more familiar with it. If you would give yourself some time to become
accustomed to Vista, you might find that you like it. I know I do.

2. You can't literally "uninstall" Vista, but if you want XP instead, you
simply do a clean installation of XP the normal way. That will format the
drive, removing whatever is on it.

3. Do you already have a copy of XP you want to install? Did it come with
your old computer? If so you need to be aware that OEM versions (such as
those that came preinstalled on computers) are permanently tied by their
license to the first computer they are installed on. If that's your
situation, your copy of XP is not available to be used on your new laptop.

4. Over and above the licensing issue in point 3, many OEM version of
Windows XP are BIOS-locked to the computer they came with, and you actually
won't be able to install it on a different one.

5. You should check with your vendor to be sure, but the warranty on your
new computer may be voided if you change operating systems.

6. Laptops often have special drivers they need for components within them.
Your new laptop undoubtedly came with all the drivers needed for Vista, but
it didn't come with the drivers needed for Windows XP. Finding and getting
the drivers you need may be a problem.

If I were in your shoes, I'd stick with Vista.

If you still want to uninstall:
The normal way to "uninstall" any operating system is to format
the hard drive and install a new OS of your choice.

After backing up any data you wish to transfer to the new OS
installation, simply boot from the WinXP Home installation CD. You'll
be offered the opportunity to delete, create, and format partitions as
part of the installation process. (You may need to re-arrange the order
of boot devices in the PC's BIOS to boot from the CD.)

Then the backed up data can be restored and applications re-installed.

You can even try a dual boot, where you have both Vista and XP on the same system. Click HERE for pictorial guide.

Your hard drive maybe failing. I would make a back up as soon as possible . Then I would do a dskchk, Here's how:

Double-click My Computer, and then right-click the hard disk that you want to check.

1. Click Properties, and then click Tools.
2. Under Error-checking, click Check Now. A dialog box that shows the Check disk options is displayed,
3. Use the following procedures:
• To repair errors, locate bad sectors, and recover readable information, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
Note If one or more of the files on the hard disk are open, you will receive the following message: The disk check could not be performed because the disk check utility needs exclusive access to some Windows files on the disk. These files can be accessed by restarting Windows. Do you want to schedule the disk check to occur the next time you restart the computer? Click Yes to schedule the disk check, and then restart your computer to start the disk check. Please don't forget to rate this solution.

probably itz either minor case of software corruption/improper ground/cpu fan..
or major case of faulty or defective main board/ram/daughter or addon card(s)..

..plz do check the following as in order:..
the Hardware part:..
1)a)in power on mode, open/unplug the data/vga cable of the monitor fromcabinet..see if raster or 'osd' is appearing on the monitor screen..ifso monitor is ok..else replace the monitor and see..[not applicable in case of laptop]..
b) in case of laptop try to get output from external display unit/monitor using vga port..if there's proper display in there..the problem is probably with either the 'lcd' or 'ccfl' or 'inverter circuit'..

2) if u hv a graphics card, replace with a standby or onboard and see..[not applicable in case of laptop]..

3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..

4)seeif the ram(s) is loose/faulty..open clean/remove carbon & or oxideformed on the teeth with an eraser n resit it..or replace with a standbyn see..

5) a) see if ur hdd is noisy or emitting any 'ticking'noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to breplaced..

6)remove/clean dust neatly..dust is non-uniform innature n may cause jam/short circuitry/excess resistance n manymore..resulting an increase in heat..

7) open the CPU Heat-Sinkwith fan out of the socket..put some "Heat Sink Compound" (available inlocal electronics chip level spare market) between the cpu/processor andthe CPU Heat Sink *** fan..resit/fit it tightly in position..

8)on main/mother board..see with a debug card for mb error..may bshort..look for defective capacitors(esp above1000mfd)/mosfets..gothrough the mb's south bridge n the circuit lie around atxconnector..the crystal clock generator (if cpu isn't heating up)..

9) [in case of desktop] the smps itself may b defective/faulty..check the outputs of smpsviz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg& grey~sb); -12v (blue); -5v(white); +3.3v(orange)..the 'oscillator and error amplifier ic', orpwm switching regulator circuit..look for defectiveprotector-transformer/resistance(esp 4.7k)/mosfet..
check the battery n adapter [main power], in case of laptops..

the Software part:..
1)hv a licensed and UPDATED antivirus installed (iprefer avg/kaspersky, remember, without updation a full version antivirusis useless)..

2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en..

b)'Error Reporting' right click onmy computer->properties->advanced->error reporting->disableerror reporting->(uncheck on the) 'but notify me when criticalerror occur'..

7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880

if u r bot a professional, always better to seek advise from ur system admin/vendor....
