I want to upgrade the processor and add second hard drive to pavilion a6152n

to upgrade the hard drive space capacity of your pc you need to buy another hard disk drive and add it to your computer....

The cpu is non- upgradable as it is soldered to the motherboard.

The maximum upgrade would be a 3.4 Ghz CPU, you would not see any difference in day to day use.
Your max memory is 4GB, if you are using 1GB or less, you would see a big difference upgrading to the max.
A hard drive upgrade may also see some benefits.
Some info for you here ...

The Dimension 5150 has a BTX case, which is nearly impossible to upgrade. The motherboard is NOT interchangeable (with a few exceptions, but none of which are true upgrades).

If you have a PCI Express slot, you can upgrade the video card but do not get a card that requires an additional power cable directly from the power supply. This is because the stock power supply is very weak and doesn't have outputs for additional cards. If the card requires no additional power, you should be fine.

You can upgrade your processor with the P4 [Prescott] 5xx or 6xx Series Processors with HT. The 5150 does not support core 2 duo processors. Depending on what you currently have, this may or may not be worthwhile. Also note that higher power processors run at higher temps, which sometimes causes a noticeable increase in fan noise.

The hard drive is easily upgradeable. Just buy any standard sized SATA hard drive. Your computer case supports two drives, so you could keep your current drive and just add a second drive. Remember to buy a SATA cable with the new drive because new drives usually don't come with them.

Overall, if you're looking to get outstanding performance, get a new computer. BTX computers are not gaming computers. You'll end up dumping money into this thing just to get a lousy increase in performance.

No you do not need to upgrade the cpu after upgrading the memory. The best processor is likely the one in it, however it may support other processors in the same family (ie, if it supports the i7 processor it may support any i7 processor, 1ghz or 2ghz, or if it's an amd turion 64 x2 tl-56 it should support the tl-58 and others. Be sure to purchase a new cpu from somewhere that does offer returns if it doesn't work.)

Thanks,

Instead of buying a new computer, you can go with installing memory and hard drives. it will be cheaper.

insteading of changing the motherbard for making it fast try upgrading the memory cards it add extra memory stcks in the computer to make it faster...

Techguru2009: When you upgrade your motherboard, basically you have a new computer. You need to know how your hard/cd drives are connected. Either IDE or SATA. IDE is legacy hardware 80 pin and SATA is the new Thing small connecter. Next is your RAM. There is Dimm, DDR1, DDR2. Find out what your old system was using, or just buy new memory cards, DDR2 is not that expensive. Ask for the manual first read and check what is required, take a list of what your old computer has. I can also help you install everything via chat.

If you are a gaming person, then a new one, if not and the processor is around 1.6ghz or above the i would upgrade.
