Guys, I bought a branded Compaq Presario way back in 2002. My configuration was this:- AMD ATHLON XP 1800+ @ 1.53 GHz VIA GA-7VKML MOTHERBOARD 128 MB DDR 266 MHz RAM SEAGATE 40 GB HDD I updated my configuration and added a GeForce FX 5200 128 MB RAM, Creative Soundblaster Live! 24 Bit, 5.1 Creative Inspire 5200, 400 WATT SMPS and an ASUS DVD Writer. Everything was working just right, but about a month ago, whenever I started my computer, I would hear 8 beeps and no display.I did my best to troubleshoot this thing, but it didn't work out. I gave it to a shop and they are saying that everything is working fine except the motherboard. I asked them to give an estimate, and they said that it will take time. I said okay and the first thing that came to my mind is ''upgrade''. So guys, I wanna upgrade to something cool. Here is what I think, I would upgrade too :- Intel Core 2 Duo E6600 (2.4 GHz, 4MB L2 Cache) Intel Original 965 Motherboard 1 GB DDR2 667 MHz Transcend RAM 300 GB SATA 2 HITACHI XFX GeForce 6800 GT 256 MB GRAPHICS CARD iball Cabinet Now here is the thing, I am still confused whether to go for the Intel Original Motherboard or a NVIDIA SLI based one and, I was planning to buy Geforce 7600 GT but since it doesn't support DirectX 10, i said to myself that I would wait, buy a mid range card for now and after a year, upgrade to GeForce 8800.One more thing, I have this standard keyboard and a ball mouse. Should I upgrade that too? I have heard that optical mouse and wireless keyboards causes problems. So what do you say guys? P.S. I would also be happy if you recommend a configuration of your choice based on (Processor, MB, RAM, HDD, GRAPHICS CARD, Cabinet, Keyboard, Mouse). My budget is around Rs. 35,000 to Rs.45,000, but would be happy to shell out under Rs. 40,000.
