Hi, I've recently had some issues with my hp pavilion a1020n and am thinking of a mobo upgrade. I've read that I'm unable to upgrade the video card unless I completely change the mobo. I eventually would like to change my processor as well, but am not sure as to which mobo would fit the hp tower. here are the specs copied from hp: Hardware Base processor Pentium4 519 (P) 3.06 GHz: 533 MHz Front side bus Socket LGA775 Chipset Intel 915GV Motherboard Manufacturer: Asus Motherboard Name: PTGD-LA HP motherboard name: Goldfish3-GL8E Motherboard description * Motherboard manufacturer's name: ASUS PTGD-LA * HP/Compaq name: Goldfish3-GL8E CPU/Processor * Socket: LGA775 * Supports processor up to 3.4 GHz * Supports Intel Pentium 4 HT processors Front-side bus (FSB) * 800 MHz Chipset * Northbridge: Intel 915GV Graphics Memory and Controller Hub (MCH) * Southbridge: Intel ICH6 BIOS features * 4Mb FWH EEPROM * HP BIOS with enhanced ACPI, DMI, Green, and PnP Features Plus Form factor * Micro-ATX form factor, 9.6 in x 9.6 in Memory * Dual-channel memory architecture * 4 x 240-pin DIMM sockets support unbuffered non-ECC 4 GB 533/400 MHZ DDR2 memory modules * Maximum HP/Compaq approved memory is 4 GB* NOTE: *Actual available memory may be less Expansion slots * Three PCI * No AGP slot Video graphics * Integrated Serial ATA * 4 SATA connectors * Each connector supports 1 serial Ultra DMA 150 disk drive * Hot Swap function Onboard audio Realtek ALC880 8-channel High Definition Audio CODEC Onboard LAN * Realtek RTL8101L LAN PHY (Physical Layer Protocol) * 10/100 Mbps Fast Ethernet controller any help would be great! thanks so much!
