Last week there were a couple of times when the screen started to have little squares on it. Now when I try to boot up my pc it will either bring up my sign allowing me to sign on and then show the little squares, or simply beep at me in mutiple forms about three second apart.

Try booting into "safe mode" before you do any repairs on it.
Start your computer and hit F8 every second until the boot menu comes up. When it does select "Start in safe mode". If it starts up and you can see your desktop (it might look a little bloated), then you just need to update your video card driver because it somehow got corrupted.
First, boot into Safe Mode (Repeatedly tap the F8 key while the system is booting, before the windows logo appears) A Menu will pop up, press Boot Into Safe Mode. From there you can try a System Restore to a known good date.
System Restore - Click Start -> Control Panel -> On the top right, type "System Restore" without the quotes. Click on "Restore system files and settings from a restore point". You can choose the recommended restore or a specific date.
The other option is to boot into "Last Known Good Configuration". To do this, use the F8 trick again while booting, but instead of Safe Mode choose "Last Known Good Configuration".
Please note that either of these run a risk of some data being lost from the time the restore point was made. You "shouldn't" lose anything but just want to make you aware. If this helps, please give a positive rating.
First try to do monitor self test.Disconnected the blue cable VGA or white colour connector from monitor to the computer. Turn on the monitor and check if you are able to see colours or line on the monitor.Indicating self test monitor is working fine. If you are using Video card on computer connect monitor directly to onboard video and check. Good Luck.
An HP Laptop? Try pressing FN (lower left rows on keyb) and then F4 which forces the PC to switch video output from the LDC (Screen) To the VGA Out on back of PC, to Both!
Another possibility is that the VIDEO selections you have made are too acute for the screen and Windows cannot continue (nor can it tell you it can't) so press F8 key while booting, select 'Last known Good' and see if that flies. Last known good is the settings for your PC that worked last time you booted. If that does the same thing, then reboot using F8 again and select 'Safe mode'
This will force WIN to use only known good settings, and then you can fix the problem by START, RUN and typing 'compmgmt.msc', choosing 'Devices', clicking the little + by Display Adapters, highlighting yours and hitting the DEL key. This will remove it and its settings from the Registry (but not the HD) and force Windows to reinstall and reconfigure it
try to boot into safe mode, to do this restart the pc and as it boots hit F8 repeatedly, this will bring a sub menu up and choose safe mode, when in safe mode perform a system restore and take it back a week or so
I hope this hepls and please don't forget to rate us
HI, First thing you want to do is to start the PC and while its booting press F8 two or three times.
If you've done it properly a screen with couple of option will appear. Choose the LAST KNOWN GOOD CONFIGURATION.
The PC will then try to start Windows.
If it doesn't work try the same thing but this time choose the START WINDOWS IN SAFE MODE option.
If it still doesn't work you will have to reinstall your OS.
Hope it helps
Please let me know if you need anything
my advice is to uninstal Go back as sometimes it stops the boot process, but you may have a faulty drive, so first try starting in safe mode (Pressing F8 on boot up), select safe mode and if it boots into windows you know it's not a hardware problem, but a software one.
When you can get it to start, go directly into the bios. Once there find hardware monitor. (if your bios supports that). If so, here you can monitor cpu & motherboard tempture. Just let it sit. If its a heat issue you will be able to see it in the bios. Also lets see if the pc restarts by itself. If no restart takes place I would guess this is a software issue. Possible virus/worm. Pull the system memory & reseat. Reinstall windows.
