Thank you for the suggestions. I really appreciate it. Anyway, I found my receipt of my previous cpu hardwares. This are the hardwares:
Intel pentium dual core E5500 2.8Ghz/2mb L2 cache/800fbs/42nm lga775
Elite G31T-M7 S775/C2D/1333MHZ/DDR2 800/PCI-E/V/S/ LAN
KINGSTON 2GB DDR2 PC800 MEMORY
SEAGATE 500GB 7200RPM SATA
SONY DRU-870S 24X SATA BLACK DVDRW
COLTECH ALL-IN-1 INTERNAL CARD READER
INNO3D GFGT220 PCIE 1GB GDDR3 128BIT VGA DVI HDMI VIDEO CARD
BLADE 5020R RED BLACK TRANSPARENT SIDE PANEL W/ 80MM FAN
COOLERMASTER 460WATTS ATX REGULAR V2.3 POWER SUPPLY
WINDOWS 7 HOME BASIC
This hardware's was 4 years ago. And when I'm playing HoN this past few days my computer is freezing and I cant do anything but to switch it off. Now I want to upgrade some of it, so that my pc wont freeze anymore. I use my computer 4-5 hours a day. I think my budget will be lowered to 200-300$ because I will just buy certain parts that are needed. Thank you again!!
