MY CPU IS UNDERPOWERED HOW DO I FIX IT? - Microsoft Windows Vista Home Premium with Service Pack 1: Windows

most CPU are slow , you get what you pay for, just like slow cars are slow. T4200 core 2 is slow. and is OLD.
impacting performance doing what? PC can do 10,000- things, I can not guess what you do. or if online or offline slow.
NO OS told at all nor version, just the word OS. must we guess the topic?
old PCs are 32bit.
and 32bit OS
2 to the 32nd power is 4GIG. (do the math see?)_ calculators.

4GB of ram ,is 3.2GB to make that lame GPU chip use DDR aS VRAM
'as the GPU has no VRAM there, so STEALS it.
intel even uses that word in their data sheet (chipset g45)

chrome OS or Chrome browser ,what?
no version told

the sales add shows 3GB OF RAM That is round down from 3.2
and is 750MB below 4GB physical RAM seen in BIOS page 1.

the limits are Manifold
the old core2, CPU
the limits of GM45,. chip set.

see the limits on G45 (m = mobile) lost at intel now but is here
DDR2 only on your PC. 2 slots, 2x2 =4GB minus VRAM theft.
means 3.2GB;. some PC
some models then were sold with 1+2=3GB , to save costs.
2+2 is max, here, that is a hard cold fact of life G45.!!!

load Ubuntu on this old dog and be happy, as vista is NOT IT.

better is buy a used i3 or up ,far far far better PC.
any PC,
not this dog.
go i5-4xxx or higher, means gen4, for a longer supported future

Maybe timing is retarded?

Heather,
Before you make any physical changes to your current system read this and get back to me. Now.... just on a fundamental level once we identify what EXACTLY we need to accomplish what you NEED, futuristically it might here be suggested that you may have to purchase a higher wattage power supply. Based on my speculation of what you've provided tus far, your power supply is either going bad or its wattage is in the neighborhood of 185-300 Watts. It is here suggested when one is upgrading their system, it is a decent idea to upgrade the power supply as well. Keep the older one just in case. By the way, which fan are you striving to repair? If it's the cpu fan we'll probably replace that too. All of the previous is offered only if you have just a few budget constraints. Relative to creating a partition... are you speaking of your hard-drive? Kindly provide me with a System Information report. What operating system are you using, and what computer system do you own: Dell, Acer. Compaq, HP, etc.?
I await your response. And please don't worry... we'll get it done!

I suggest that you take it to a repair ship and have them hook a machine up to the computer in your car to do diagnostics so then you would know what exactly is going on so you could fix it once and for all.

Very likely. Check Performance in Task Manager. 100% CPU Utilization is common on older computers. This is a decision you must make on what your needs are.

If you're speaking of the Windows Experience Index, ignore it as it isn't a good indicator of performance or quality. I've got a 2 Gb 1256 GHz video card in an SLI configuration I can run full resolution at 120 fps. According to the Windows Experience Index my video card is 7.1 gaming rating but under Astro it only ranks 4.3 and thus regardless of how fast my 8 core machine is (4.8 Ghz) with 32 Gb 1600 RAM, my index rating ultimately is based on the lowest number.

this is operating system problem. Re install your o/s

Has this problem been resolved? My immediate suspicion is an underpowered peripheral--do you have some sort of expansion card or adapter in your Express Card slot? If you have something like a USB 3.0 adapter or TV tuner card, remove it or provide it with an external power supply.

try a new power supply first. There is a light on the board that comes on when the power supply is plugged in.

It is possible the power supply is now too small for the number of loads you now have.Not sure what your CPU is ,but I bet it is 80 watts just by itself. The minimum wattage requirement or the video card by itself is 300 watts.Add the drives,ram,fans and mobo and you way underpowered.
