Turn off computer. Turn on computer and tap the F5 key once every second. A login in screen should pop up. Select safe mode with networking.
This should boot computer into safe mode. Run anti-virus software from there.
Hope this helps
There's no reason to flash your BIOS they rarely add enhancements to BIOS's usually just bug fixes. Plus it's dangerous to flash it unless you know exactly what you are doing if you half flash something then it's toast flash is either all or nothing.
Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htmTesting & replacing the PC's power supplyhttp://www.youtube.com/watch?v=hbNxhvm0czs One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the memory modules from their slots. Take the opportunity to clean the slots on the motherboards and the memory module connectors. Use compressed air to blow dust away and clean contacts with a soft cloth. Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components. Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r Allow the pins to dry. They will air dry in a matter of minutes. If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer. Check the memory module and memory slot contacts. They are either copper tin or gold. The colour will tell you which they are. Mixing tin and gold can result in corrosion that prevents proper contact. Look for any sign of physical damage to the memory module, memory slots or the motherboard. Reseat the memory modules. You should hear an audible click when they are in place. Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard. The hardware that you are trying to access is damaged or failing. The device drivers for the hardware are faulty or incompatible. Could be a problem with the Hard Drive or the Hard drives PCB http://www.onepcbsolution.com/http://www.youtube.com/watch?v=du0Qd_3wFWM There is a connection problem such as a bad cable for internal hard drives Test all power and data leads that attach to your hard drive SATA the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a secure dust free connections and are not faulty although very rare for sata lead to fail Make sure all leads that are attached to your drives dvd\cd and floppy (If Applicable) have secure connections and are not faulty. or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error
The beeps are possibly post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Make sure that your RAM modules and Cmos battery are securely seated on some motherboards Cmos batteries are soldered in. Open computer and reseat memory Sometimes when the computer is moved or over time a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it. Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer and then placing them back into the computer. Swap memory location If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer. If you have more than one stick of memory try removing all but one stick of memory and boot the computer. Remove the memory modules from their slots.

Try another computers memory Test all power and data leads that attach from motherboard to your hard drive IDE SATA make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty If its a flat 40 pin ide it will be the first to fail. Check the graphics card is seated properly with no dust in the socket you might have to remove it to check for dust reinstall it Restart your computer the found new hardware wizard should activate a computer needs power and data to travel through every working device and to its continue its cycle and to have and end to function Make sure all leads that are attached to your drives dvd\cd and floppy drive have secure make sure the connections and are not faulty or just replace them they could be faulty Computers need all Power and Data to travel to and through every working device and have an end to work properly so any faulty leads will end up with a computer error also check the keyboard for secure dust free connection ps2 and or usb
sounds like a bad power supply... get one from newegg.com they are easy to replace, it will only plug in to the place it is supposed to.... check wattage out put and get same or higher
You are having what is called a BSOD(Blue Screen Of Death). Usually it is software related but in your case if it's not booting up then you have a hardware malfunction. Check your motherboard for any missing cables. Chances are you will have to get a replacement for your motherboard. Have fun :)
Press CTRL + ALT + DEL - the Task Manager should appear. If it does then click File, New Task (Run) and type explorer then hit enter, it should return to normal. If the Task Manager doesn't appears or Explorer doesn't starts then the system is severely corrupted, you will have to reinstall Windows using the recovery cd.
try hooking it up to an external monitor through your vga jack and see if the sceen appears on the external monitor first. if so then its most likely a bad back light on your laptop screen or inverter
Have you checked your display settings in the control panel. Check the device manager also to see if any of the drivers are incorrect, but it sounds like the screensaver is starting up and it's a blank screen or something like that. What O/S are you running? WIndows and what version?
should be easy to pop it out unless it is soldered in, usesualy they are the cr2032 type button batteries, open case and look on the mobo . push back the little metal tab and it will pop up
To clarify with you did you actually do the system restore of the system back to the factory image or just to a restore point.
Also what games are you trying to play. If they are online games you may need to have your Active X settings adjusted for the game and installed the versions of JAVA that the game requires.
Let me know if you have any more problems or questions
have you checked device manager to see if your sound driver is installed to access device manager in xp you go to start run and type devmgmt.msc in vista and windows 7 go to start>start search>type device manager if you soundcard isnt installed it will appear as multimedia audio contoller then you will have to download the driver from emachines website Http://support.emachines.com
