PC Freezes on Internet

My Computer is freezing when I access the Internet, I am unable to raise Task
Manager and therefore have to shut off manually using the on/off button.

I have the following in my PC – AMD Athlon XP 2000+ 1.66Ghz processor, 512MB
RAM (2x256) Ram PC2700 DDR -184 pin 333Mhz DIMM (32x64), Motherboard – Jetway
V400DB/V400DBL, Seagate 60 GB hard disk, Virgin Broadband..
The problems started a week ago when I installed additional memory, I have
three memory slots, I purchased 512 memory upgrade (1x512) this was placed in
the first slot with the 2x256 placed in the second and third, Jetway
instructions do no say that all slots have to contain the same amount of RAM
and that the system will work as long as no more than 3GB of memory are
installed.

I have been unable to do a System Restore under three separate dates but
finally went into SAFE Mode to carry out this task which was successful.

I have reduced my RAM to the original but I am still having the same problems.
Any help would be appreciated.

The main thing with RAM is not the same amount in each slot, but the
same speed. If they are different speed, the slowest must go in the
first slot - then all RAM will run at that speed.

You might try running a ChkDsk /f at a command prompt. Files could have
gotten scrambled while you were having problems.

Sometimes we focus on what we think the problem is and don't think about
other possibilities. You can't hardly go wrong scanning your machine for
viruses and malware also.
