well until no so long I was working in my office with a similar machine, there are a few things you can do;
this is your system; (taken from link)
Operating System
Windows 7 Home Premium 64-bit SP1
CPU Intel Core 2 Duo E7500 @ 2.93GHz: Wolfdale 45nm Technology
RAM 4.00GB Dual-Channel DDR3 @ 531MHz (7-7-7-20)
Motherboard Dell Inc. 018D1Y (CPU 1): 45 °C
Graphics DELL ST2210 (1920x1080@60Hz)
Intel G45/G43 Express Chipset (Dell)
Storage 931GB Seagate ST1000DM003-1ER162 ATA Device (SATA): 35 °C
Optical Drives PLDS DVD+-RW DH-16AAS ATA Device
Audio High Definition Audio Device
Looks like you own a Dell Inspiron 500 Series probably a Dell Inspiron 560 MT or 560S ??
According to sources on the internet while looking for your Dell Motherboard model no.018D1Y
- I found that it could be pushed to 4 x 240-pin DDR3 DIMM slots – Dual Channel DDR3 1333/1066 MHz non-ECC, un-buffered memory (Max 8GB)
- The Video PCIE slot is a 1 x PCIe 2.0 x16. which in itself should not be an issue because more recent v3.0 should be backwards compatible, but if a video card doesn't work on it, could be a bios or incompatibility.
- CPU supported on a LGA775 Die would be Support Intel Core 2 Quad, Core 2 Duo, Pentium Dual Core.
- Designed by Dell inc. 018D1Y to Support Operating Systems: Win 7/8, Vista/XP
- power supply that comes standard with the 500 series is 320w (important when picking a new video card)
Considering 8gb of DDR3 4x2gb will cost about 65$, say a GTX 1050TI/RX470 will run you in about 130$
those are basic upgrade you can do, now when it comes to upgrading the cpu (not that I was able to narrow exactly which dual core 2 quad it allowed yet,. but assuming best possible scenario a Q9560, that runs, used, 100-150$ easy.
a new cpu fan 30$ and your done... so total 65$+130$+150$ = 345$ no including taxes rebates etc.
you could upgrade the system to a brand new G4560+ Mobo +Ram + video card for ; 305$ and be in this millennium.
