More Hard Drive Space needed

two things:

your RAM's its not fitted right or in right spot.

too small power supply, its to narrow in watts, should have 750 Watts at least.

HI,
chances are that you simply do not have the resources to run windows 7. These are the basic (recommended minimum), for windows 7

• 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor.
  
• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit).
  
• 16 GB available hard disk space (32-bit) or 20 GB (64-bit).
  
• DirectX 9 graphics device with WDDM 1.0 or higher driver
  
• 1 more GB of RAM & 15 GB more HDD space to run 7 in XP Mode.
  

These are the typical resources that come with your machine.

D510HI

• Processor Pentium M 1.73 GHz

• Ram Installed Size 512.0 MB
• Technology DDR2 SDRAM

• Hard Drive 40.0 GB

• OS Provided Microsoft Windows XP Professional

It would probably be advisable to go back to XP
Good luck

yes you can. it must be the same type but you can go any size. this link tells you the specs on your pc and the different hard drives that came with it. also shows the maximum memory that can be installed.

Yes, there is. Match the type of drive (Serial ATA or Parallel ATA) you get with what you have. Make sure your Satellite sees the drive in the BIOS. For drives larger than 120 GB, recommend operating systems Windows XP (Service Pack 2 or higher) or Vista. Older OS's have a 137 GB limitation (they only see the first 137 GB of the hard drive despite its size).

try reading the hard disk drive myths....it may explain more.

According to intel:

1.6 System Memory
The Desktop Boards provide the following memory features:
• Two DIMM sockets supporting one of the following10:
 2.5 V (only) 184-pin 200/266 MHz Double Data Rate (DDR) SDRAM DIMMs with goldplated
contacts, or
 3.3 V (only) 168-pin 133 MHz Single Data Rate (SDR) SDRAM DIMMs with gold-plated
contacts
• Unbuffered non-ECC DIMMs only
• Maximum total system memory: 2 GB; minimum total system memory: 64 MB
• Serial Presence Detect (SPD) DIMMs only
