Re the missing 64MB of RAM - that would imply you have onboard graphics and have allocated 64MB of system memory to their use. Hence the System RAM now becomes 192MB.
Testing your RAM is easy enough. There is a free RAM diagnostic called Memtest86 which you can download from here Memtest86
Use it to create a bootable floppy disk. When you reboot with that floppy in the drive it will automatically run a memory test. Let it run at least overnight, unless errors come up right away, and then examine the error count.
(If you have no floppy drive there is an iso image available to create a bootable CD.)
What are you using to see the temperatures?
The new power supply you installed - was it identical to the old one?
Check on the manufacturers website for updated drivers for the motherboard (esp all the onboard devices) and install them.
Is there a model number for the PC?
Soltek QBIC, Pentium 4 3.0GHz, 512MB RAM, 200GB SATA HDD, ATI Radeon 9600XT 256MB, Netgear 54Mb/s WAP, ridiculously expensive Satellite Broadband
Windows XP Home SP2, Trend Micro Internet Security, Firefox, Thunderbird, AdAwareSE, Spybot S&D, SpywareBlaster, A-squared Free, Ewido Security Suite.
