As the title says, what are the possible causes for this problem?
OS: Windows 7 Ultimate x64
PSU:Cooler Master
RS-700-AMBA-D3
Input Voltage 90~264V (auto range)
Output Capacity 700W
HDD: HD Sata 1TB WD Caviar Green 64mb CA
MOBO: s1366 intel core i7 BLKDX58SO
Memory: 2 Units Kingston 2gb DDR3
1 Unit Kingston 2gb (but smaller in size)
CPU-Z and GPU-Z
I think my rig is not that slow considering its specs but it takes 1.50~2.1 minutes during boot up. I already tried reformatting and reinstalling the OS before (4 months ago i guess) and this doesn't solve the problem.
Can this be a hardware problem? I just fixed the beeping sound in my pc today which was caused by RAM problem (dri nako napalit sa istorya ang ram. haha..

) so dli siguro ang ram ang cause why dugay mo boot or maybe sa Hard Disk naa prob?
