My computer is a dell and it keeps killing programs and protocol errors keep appearing then there are many runtime errors. The dell is old but its been kicked alot. its a demention 2400 with 256 ram... the memory was upgraded, its not the original memory... its a maxtor... and it has 74.4 gb... i just repaired it, searched viruses, malware, adware, spyware... None could be found. the computer runs slower... but the hd lost most memory to dled stuff... yea... i have still half the memory... but it couldnt of been wiped out that much! so how can i make the computer faster and it stop them stupid protocol errors!
