DRIVER_IRQL_NOT_LESS_OR_EQUAL blue screen error randomly

hi

my computer has a list of problems. i have tried using malwarebytes anti malware but the computer crashes while scanning. I used chkdsk using the windows recovery console and it worked but it did not fix anything.i have also tried to system restore but the system restore function seems to hang and it won't get past next to start it. here are the list of problems

1. cannot boot into safe mode. goes straight to blue screen of death with no error. it just tels me to use chkdsk
2. computer randomly restarts and gives me the DRIVER_IRQL_NOT_LESS_OR_EQUAL blue screen error.
3. cannot use malwarebytes to scan because it leads to blue screen

i also could not get into task manager but fixed that before. the computer i am using is a DELL XPS 400. i'm thinking this is a virus problem or malware problem. another symptom i've been having is fan in power supply is making noise? could that be the problem? can youguys help me? thanks.

Moving to Am I Infected forum for you.

bump please

I had a similar problem in the past with my old pc. At first I managed to get it to boot by removing all cables from my hard drives, and re-fitting them. It booted fine. But it kept repeating over time ( always cured same way ). I did several things, I replaced the Hard Drive, I replaced the IDE Cable ( old pc ). And the problem repeated, but always curable with re-insertion of the wires. In the end I got a new pc, But in my own opinion, I think the motherboard was naffed.

Just thought I'd tell you what I did, and what to possibly look out for in the future.
