Many thanks for your interest, my system is as follows:
GA-H55-S2H Rev. 1.1(According to my computer System Information, it is listed as BIOS version/date F6 7/6/2010)
Presently installed CPU is Intel i3-530 2.93Ghz
ATX 650 Watt PSU
2x2GB Patriot PSD32G133381 PC3 RAM modules (info on RAM module PS000811 26B PC3 10666 CL9)
500GB wd hdd
Nvidia Geforce GT630 graphics card
OS Windows 7 Ultimate
The CPU I am having difficulty upgrading to is Intel i5-750 2.66 ghz (info on cpu--SLBLC Malay 8m/09B L940B537)
I have to admit I feel a bit out of my depth when talking about compatible memory modules etc,(I had spoken to the local PC repair shop today about putting it into them to sort out, but being a tight scotsman I loathe to do that) anyway I thank you in advance for any assistance.
