my computer keeps restarting itself randomly it mostly does it when im running a scan with avg why would it do that?

Please click here to download and install the HijackThis installer.

Run it and select Do a system scan and save a logfile.

The log will be saved in Notepad. Copy and paste the log in your next post.

Do not fix anything

Your computer could be over heating but if happening when you run AVG it's probably bad RAM.

You also might have a virus, use another virus scan like Housecall.

If determined that you don't have a virus then try replacing each stick of RAM with a known good one.

Make sure your Fan's air hole isn't blocked. If it is modern computers just shutdown to prevent fires.

it keeps shuting down now thats why its taking me so long to do this stuff. One time that it shut down a blue screen came up saying it was checking the disc something

[Phantom010]

You should consider overheating as it looks like a most probable culprit. Clean up the dust and perhaps use a portable fan directed at your components to see if it increases your up time.

Could you please show me a few of your latest minidump files? They are located in C:\WINDOWS\Minidump. Zip them and attach them to your next post.

[alycia317]

well this computer has done this befor and right after it started I had 2 hard drives go out on me I took it to the shop and he put this one in and it just keeps shuting down im prety sure my fans are fine

[Phantom010]

It could be the Power Supply.

[alycia317]

what do i need to check for the power suply?

[alycia317]

could the computer restarting make my hard drives go out

[Phantom010]

Power Supply

The symptoms
Just about any intermittent problem can be caused by a faulty power supply. I normally look there first when the symptoms are a little weird. Common power-related symptoms include:

• Any power-on or system startup failures or lockups
• Spontaneous rebooting or intermittent lockups during normal operation
• Intermittent parity check or other memory-type errors
• HDD and fan simultaneously failing to spin (no +12V)
• Overheating due to fan failure
• Small brownouts that cause the system to restart
• Electric shocks that are felt when the case is touched

There are also some obvious clues that should lead you to suspect a faulty power supply. These include:

• A system that is completely dead (nothing happens when the system is turned on)
• Smoke
• Circuit breakers popping when the PC is turned on

Power Supply

Measure the output voltages
One of the simplest tests you can perform on a power supply is to measure the output voltages. This will show whether the supply is operating correctly and if the supplied voltage is within the proper tolerance range. Note that you must check the output voltages while the supply is under a load, which means that it will be installed and running in the PC.

Caution: Power supplies can be dangerous
I do not recommend that any inexperienced person open the cover of a power supply. Even when unplugged, a supply should be considered dangerous. Capacitors can maintain a line voltage charge for a considerable period of time. Shorting one by mistake feels just like being electrocuted by 120 volts from a receptacle. If you are unsure or uncomfortable with working around high voltage,don’t!

Use the right equipment
Most of the experienced technicians I know use good quality DMMs (digital multimeters, see Figure A). These can range in price from just under $100 to well over $300. The price normally reflects the number of special features built into the meter. This type of meter is preferable to the older analog VOM (volt-ohm meter) because the DMM injects only 1.5 volts into a circuit when conducting continuity tests, while a VOM typically injects 9 volts, which is enough to damage a PC’s sensitive electronic components.
