System Restore (need to be in "normal mode") & Last Known Configuration don’t help.

I had Symantec Anti-virus w/Live Update, but that has not been performing well lately and I deleted it as Live Update was not actually Live Updating it. Any anti-virus software I dl, it refuses for some odd reason. What I do have installed is Malware Bytes & Wise Registry Cleaner 4.

I have seen most tech forums on the Web and none of them have been providing me a right answer, so I will take suggestions from here. Thanks to those that help me, I truly appreciate it. 🙂

Compaq presario 5000 desktop series my hard drive is 20GB SDRAM 128MB CPU intel Celeron 800MHz Bus speed 100MHz, windows 98 DC rom. HOW to speed it up windows 98. will Registry Cleaner work

I was wanting to clean out the junk files in my computer without purchasing a program to do it. This question is directed to a computer geek or someone with this knowledge. How do I delete or clean out the junk files in my computer for better performance? My computer is a couple years old and is a Compaq Presario SR1130NX and I use Windows XP. Thank you for whatever advice you send to me.

My computer is really messed up but it didn't come with any sort of disk…Its a Compaq. On the tower it says Compaq Presario SR1403WM. We bought it from a store. I think Best Buy or something but anyways it would be way out of warrenty by now. It has been years. I want to start it fresh (system restore wont cut it) and even if I did find a way to start fresh it didn't come with a windows XP disk to reinstall….My mom would have thrown the receipt away by now. HELP?

I use an Compaq Presario SR1103WM when I'm at my Dad's house. We've had it for about 2 or 3 years, and used it for everything from games to internet to whatever you can think of. However, it's outdated now, but I can't afford any major upgrades or to buy a new computer right now, so I'm trying to figure out how to run it better. The only specs I know are:

248 RAM (8mb is diverted to video memory) max is 1 GB
Intel Celeron(P) 325 2.56 GHz
40 GB HD

I have no clue about what the video card is, I've had it 3 years and still can't figure it out. Sorry the specs aren't very informative, but you could probably Google the rest if you need it. Right now it's on a dial-up connection, which I only use for instant messaging. Like I said, as of right now I can't really afford to upgrade it, but here in about a month I can. We're also getting Road Runner for it, which should speed up the internet connection a bit. Besides upgrading it, what else could I do to make it faster?
Also, I have deleted a lot of old software that I don't ever use anymore, and I just figured out how to clean the hard drive, so I did that for the first time in 3 years and it is sped up slightly.
