I'm using quite of an old desktop rig. I recently replaced my 8500GT in favor of a GTS 450 ( both PALIT) which i bought last year... and my generic 550watts power supply with a newly bought FPS epsilon 700W. ISSUES: 1. Windows 7 freezes at the 'Starting Windows' logo screen. all the fans seem operational... the cpu, new video card, PSU.. 2. Windows 7 freezes even upon attempting to run Safe mode and that Repair option. Here are my specs. MSI P35 Neo3 motherboard Intel Core 2 Quad 6600 2.4ghz 5GB ram (2pcs 2gb, 1pc 1gb) 2pcs 3.5'' hdd The new hardware i attached to my desktop are: GTS 450 1024mb ddr5 FPS Epsilon 700W I'm not really very knowledgeable abt technical stuff so maybe you guys could help me.
