System Configuration: Desktop PC 2007
- AMD Athlon 64X Dual Core 4000+
- RAM 2 GB
- HDD 80 GB Samsung ATA, 160 GB dying Seagate SATA
- Windows 7 Home Basic 32-bit
- Office 2007 32-bit
- C-DAC ISM V6 Publisher multilingual application 32-bit which does not work with Office 64-bit
- Many other 32-bit applications which work on 64-bit system

System Configuration: Desktop PC 2013
- Intel Core i3
- RAM 8 GB
- HDD 1 TB Western Digital SATA
- Windows 7 Ultimate 64-bit
- Office 2010 64-bit
- C-DAC ISM V6 Publisher multilingual application needs to be upgraded to 64-bit by paying more
- Many other 32-bit applications which work on 64-bit system, and others that I do not know about as yet

Performance: Desktop PC 2013
- From time to time, becomes extremely slow; hence, yesterday I took screenshots
- Memory in use 86% meaning 7 out of 8 GB
- CPU in use 12%
- Applications running only two Mozilla Firefox and Picpick for capturing screenshots
- despite Daily Maintenance: Windows De-fragmentation and Quick Heal PC Optimization

What do I gain by -
- using a 64-bit hardware?
- using a 64-bit Operating System?

Conversely -
- what do I lose by using 32-bit OS with 64-bit CPU

If I had the choice, which one should I have opted for -
- 32-bit CPU and 32-bit OS? or,
- 64-bit CPU and 32-bit OS? or,
- 64-bit CPU and 64-bit PS?

Kindly advise.

If you could reason it out (your recommendation) it will be of additional help.

Thank you for your time.

If you install 32bit OS on the Performance: Desktop PC you gonna lose 4.3Gbs of ram because 32bit OS is capable of reading only 3.7Gbs of RAM. I'd stay with the 64bit no questions.

64 bit runs better on a 64bit processor, 32 bit will also run but will be a little less responsive. You will only be able to use 3.5gb of 8gb ram in 32bit win, whereas you will get full 8gb in 64bit win. Apps run better in 64bit architecture(personal experience). Games require more juice in x64 as compared to x86.

Thank you 1s3ct0wN and rounakr94 for your advice and I shall not replace 64-bit OS by 32-bit OS on a 64-bit hardware. However, I shall have to buy upgrade license for multilingual software to make it work on 64-bit.

This PC is barely 1 month old with 64-bit third generation Intel Core i3 + 64-bit Windows 7 Ultimate + 64-bit Office 2010. The PC began slowing down occasionally and then I started running Windows Derangement and Quick Heal PC Optimizer every day. Despite this problem persisted. Yesterday I took down some screenshots at the time of happening so. Only 2 applications were running at that time which are not at all graphics heavy. Those were Gmail on Firefox and PicPick for capturing those screenshots I spoke about. With this surprising 86% (7 GB out of 8 GB) were in use and 12% CPU.

Since I did not put 8 GB RAM for running Gmail and PicPick I don't understand what's going on despite daily defrag and optimization. Any explanation or solution?

Thanks again for your time.

2013 system: I guess by now that your hard drive has died? This is what your problem sounds like.
First thing is make a back-up of all your data ASAP, then get hard drive replaced under warranty if applicable. If not, buy a new hard drive, maybe SSD for the OS & a slow reliable HDD for your data.
